HISTORICAL: We became interested in purebred cattle following our purchase of Yankee Creek Ranch in 1978. After researching the various beef breeds, we chose Simmental. Through the use of Simmental bulls, the weaning weights of our commercial cattle increased significantly and the half blood cows were the best replacements. We then began to focus on fullblood Simmental and then on polled fullblood Simmental. Even though we didn’t participate in shows, we were caught up in the large framed, show type animals that were typical of the French and Swiss bloodlines. We ended up with a herd of 300 registered fullblood Simmental in the mid 80’s.
We became interested in the Fleckvieh breed in the mid 1980’s. The change was precipitated by two events. First, we experienced an unusual drought. We did not have sufficient stored water in our lake to properly irrigate our pastures and hay fields, See the picture of our lake in the About Us section. The snow pack that provides the water to the irrigation districts that irrigate the lower part of the ranch was lacking. During this time period, we observed that the commercial herd and the fullblood Simmental herd experienced a noticeable weight loss. At that time, we were experimenting with a few full Fleckvieh females that ran with the Simmental herd. In the short grass conditions, the contrast between the Fleckvieh cows and the Simmental and commercial cows was startling; the Fleckvieh cows didn’t show the loss of condition that the rest of the herd did. The Fleckvieh calves maintained their normal growth rate. This precipitated our decision to cull all the French and Swiss fullblood Simmental genetics and focus on German and Austrian genetics that are identified in North America as Fleckvieh.
Another reason we culled the Simmental cattle was that the market in the western United States for anything that had Simmental genetics started deteriorating. The market for traditional Simmental commercial and breeder bulls essentially disappeared. Commercial bull buyers wouldn’t look at a Simmental bull because of calving difficulties and it took too long to finish for slaughter. The trademark of the Simmental breed, a spotted color pattern, was the kiss of death at a bull sale or to a buyer at the ranch. Most of the remaining Simmental breeders in the West have moved to red or black Angus Simmental cattle. We have recently observed a resurgence of interest in the Fleckvieh breed in the west.
We noticed early on and continue to observe that Fleckvieh cattle are more fertile, calve easier, live longer, are more moderate in frame, are more muscled, have more capacity, and are an easier keeping animal than were the Swiss and French strains of Simmental cattle. The calving difficulty we and others experienced using Simmental disappeared when we switched to Fleckvieh.
The genetic foundation of our herd comes from Helga 103D and GB Cameo 101C, both of whom were purchased from Nick Berjian in 1982; HFC Miss Tino Unipolled 748J, purchased from Soderglen Farms at the dispersal sale in 1983; and two Wellhouse Kestrel x Cherry's Heidi daughters purchased from Little Pipestone Ranch in 1985. Both of these produced their last calf at 17 years of age. Along the way we purchased other foundation animals as well as bred quite a number of our own. Each of these females, and their progeny have formed the backbone of our Fleckvieh herd.

PRODUCTIVITY: We strive to produce large capacity females that will breed a year after birth, have their first calf at 2 and calf each year thereafter for approximately 15 years. They have to get by eating only grass. Fertility is a primary goal.

BREEDING BULLS: In addition to striving to produce the few bulls that will advance the breed, we want to produce easy calving bulls that the commercial and purebred industry needs to maximize the production of red meat. These bulls need to be fertile, have natural fleshing, have as rapid a growth rate to a year as reasonably possible, and have a moderate mature frame size and weight.
There is a tendency among many seed stock producers to over feed bull calves in an almost competitive race to produce the bull with the biggest weaning and biggest yearling weight. We have not engaged in this race because over fat bulls have lower fertility as well as hoof and leg problems. Who wants a bull that weighed 1600 pounds at a year but can’t breed a cow when you get him home. The research on this issue is addressed in an article written by Heather Smith-Thomas appearing in the September 2005 issue of Western Cowman, titled “Fat & Fertile?” Click here to view the entire article.
The herd bulls we have selected to use for natural breeding in the YCR herd are a great source of pride. Click here to view our bulls. While many breeders utilize bulls that are generally available through the use of an AI program, we believe that our efforts should be focused upon producing a product that is not commonly available that, in turn, can be used by a wide variety of seed stock producers and commercial producers.
Our use of walking herd bulls demonstrates our commitment to being a breeder of seed stock instead of a manufacturer of cattle. Our herd bulls provide continuity as well as enable us to breed for conformity and a consistent product in furtherance of our Serial Breeding© program. This enables us to produce separate herds of 1/2, 3/4, 7/8, and even 15/16th full sisters.
We continue to focus our efforts toward breeding the great ones through this process.

DUAL PURPOSE: While originally bred as a dual purpose breed in Germany and Austria, we focus on the genetics that will produce meat instead of high milk production. Even the low milk production Fleckvieh female, if there is such a thing, often produces more than sufficient milk to raise a calf.
(Updated 2004)

CONSISTENCY: There are considerable variations in Fleckvieh genetics. While this provides a useful and a very broad genetic base, some of these genetics produce great variations in the progeny by size, muscle pattern, structure, color, and some with the characteristics found in French and Swiss Simmental genetics. To attempt to eliminate these often unpredictable variations, we have developed and will continue to develop separate breeding herds sired by the same bull. We call this our Serial Breeding© program. Like bred females will be bred to a second bull to produce another breeding herd, and so on. Some of the results are seen in the pictures below.

COLOR PATTERN: Yankee Creek Ranch is the source for solid colored Full Fleckvieh Fullblood genetics in North America. We have had a solid color breeding program in place longer than any other breeder known to us.
Because a broken color pattern is a disadvantage at sale time, we focus on the use of herdsires that are expected to maintain a solid red color pattern with as much pigmentation on the head as is possible. The facial pigmentation is not only a desirable cosmetic feature but also helps reduce the frequency of eye cancer.
Our “red factor” program is not based upon Angus genetics that many breeders in North America utilized to obtain a solid color pattern. We decided to use the genetics already existing in this breed instead of introducing the genetics of another breed. This maintains the highest amount of heterosis possible when our breeding bulls are crossed on the commercial commercial herds in North America than if a crossbred Angus x Simmental bull will give.
We started the search for our “red factor” animals many years ago with the purchase of many females that had a lot of pigmentation on the head. Then we added Lucy and Sybil together with herdsires such as Natural and Missouri. A few years ago we began to use Neutron, a solid colored son resulting from a mating of Natural and Sybil. Painter was added in 2004 and Rojo in 2005.
Some breeders question whether it is appropriate for a seedstock producer to include color as a consideration when formulating a breeding program. I conclude it is appropriate to do so. To access an article discussing this subject in greater detail than appears above, click here.
(Updated December 23, 2008)
There are an increasing number of breeders who are using Fullblood Fleckvieh genetics to produce solid colored cattle. We have developed a cross that reliably produces solid colored offspring which are also polled.
When Nitro is breed to females sired by Enterprise, a high percentage of solid colored cattle result. Endor is solid colored and when bred to females sired by Nitro, a high percentage of solid colored offspring result. There are a number of generations of solid colored cattle in these pedigrees. Both Rojo and Painter have produced some solid colored cattle. In 2012 we will be test breed some solid colored yearling polled bulls to assorted females. Hopefully these bull calves will turn out to be homozygous polled and non-dilutors.
We have previously communicated that Fullblood Fleckvieh genetics can be used to produce cattle with solid colored bodies and heads without the use of Angus genetics. A German bred Fleckvieh bull named Neff was solid colored. Take a look at his photo appearing in an article in the April 2002 issue of Simmental Country. Click here. Neff genetics came to Canada in the early 1970’s and to the USA thereafter. The article provides a glimpse of some of the history of the early imports. Some of Neff’s offspring are identified in the article. Neff appears in the pedigree of Virginia’s Rojo, one of our principal herdsires.
On a similar subject, the commercial herds in North America are turning black in ever increasing numbers. A representative of the Angus Association authored an article that was published in the July 14, 2012 issue of Drovers captioned “Trends in hide color.” He writes that black hided cattle made up 64% of fed cattle in 2010 which is double the percentage in 2005. He predicts that by 2015 black hides will reach or exceed 75%. He also notes that 60% of the bulls turned out today are Angus. Here is the link to the article. http://www.cattlenetwork.com/drovers/markets/Trends-in-hide-color-125028789.html
The continued use of Angus genetics in the commercial herds will even further narrow the genetic base of these herds in North America to the detriment of the production of quality red meat. An infusion of genetics of the genetics of other breeds, that do not have any Black Angus genetics is required. This opens an additional door for the use of solid colored Fleckvieh genetics that will maintain color consistency as well as will add hybred vigor when used on the Angus based cattle. Otherwise, the carcass weights and rib eye size on the black cattle will continue to decrease. The author of this article has the chutzpah to write that breeding for black hided cattle “should continue to support the production of more USDA Choice and Prime-grading cattle,” implying that only Angus genetics have these characteristics. The author overlooked the outstanding genetics of the Fleckvieh breed and what the use of these genetics will add.
Seedstock producers should take the above into consideration when mapping out their future breeding program.

POLLED: Yankee Creek Ranch is THE SOURCE FOR POLLED FULL FLECKVIEH FULLBLOOD GENETICS.
We are the oldest existing Polled Full Fleckvieh Fullblood breeder in North America with the largest polled herd.
We started breeding PFFF genetics in the mid 80’s. Shortly thereafter, we began to focus our breeding program on the development of these genetics. We have now achieved our goal of producing PFFF cattle that are every bit as good and often better than the best horned cattle. It has been time consuming and expensive to accomplish this goal but we persevered because we believed it was necessary for the beef industry to do so.
The worldwide interest in polled genetics continues to gain importance because of the time needed, expense incurred, and the economic losses resulting from dehorning. There is also an ever increasing interest in animal rights, especially in the EU where a veterinarian is required in some member countries to remove horns. Recently, two events have been reported demonstrating the clout of PETA to change longtime practices in North America. The chicken industry in Canada was pressured by PETA to switch to a more humane way of slaughtering fowl and is expected to follow up in the USA. See Businessweek, July 7, 2008 issue at page 17. The wool industry was pressured by PETA to stop the practice of mulesing by putting pressure on the retailers selling products made from wool. See Businessweek, July 14, 2008 issue at page 40. Animal rights activists are expected to increase their activities in North America and this movement will impact manual dehorning practices and perhaps even result in changes of the age old practice of demonstrating ownership by hot iron branding. As a result, having polled cattle has become even more important.
There are but a few genetic lines in the Polled Fleckvieh breed because they must all trace back to a mutation resulting from the breeding of horned Full Fleckvieh Fullblood animals. The original mutation animals have been continually bred to a variety of horned genetics that have significantly expanded the number of bloodlines available to discriminating breeders.
The definition of Polled Full Fleckvieh Fullblood that we use and will continue to use has three requirements. All of the animals in our herd meet these requirements.
- The animal must be a fullblood. This means all of the genetics in the pedigree must be from original Fleckvieh genetics.
- There cannot be any genetics from another breed or grade animal.The genetics in the fullblood animal must trace back only to animals originating from Austria and Germany
- The polled feature must originate only from a mutation and not from another breed or grade animal.
There are a large number of polled lines worldwide that aren’t Full Fleckvieh Fullblood animals. Many of these trace the polled characteristic to another breed, usually Angus. In some instances, the origin of the polled genetics cannot be identified. We have not incorporated animals with the polled trait originating from Angus, other non fullblood animals or unknown animals into our herd. None of the polled animals in our herd trace back to another breed or a grade animal and none have genetics originating from another country.
It has been common knowledge to breeders of Fleckvieh and Simmental cattle since at least the late 80’s that the polled characteristics of a German bred bull named Pirol come from an Angus. There are many polled lines worldwide that have Pirol in the background. In addition to some lines in the Germany, Austria and other countries in the EU, Pirol is one of the most heavily used bulls in South Africa. He ranks 33rd out of the 100 most heavily used bulls. Animals with Pirol in the pedigree, no matter how far back, cannot be classified as Polled Full Fleckvieh Fullbloods because the polled trait didn’t begin from a mutation.
There are also a number of polled lines worldwide where genetics originating from a country other than Austria or Germany are found. These lines have, for example, genetics that come from Switzerland, France, Canada and the USA preventing the animal in question from being classified as a Full Fleckvieh Fullblood based upon our definition of this term. A polled animal commonly found in some pedigrees is Polaris. Polaris was bred in Canada from non Fleckvieh ancestors. While Polaris was a mutation, the sire and dam of Polaris were both French breeding. Another common defect to be found in a lot of pedigrees which disqualifies the animal from being classified as PFFF is that, while Full Fleckvieh Fullblood genetics can be found in the most recent generations, there are French or Swiss genetics found in the background, sometimes as far back for North American breeding as 10 or more generations. Breeders can guard against acquiring an animal with this defect by a pedigree search on the various websites as well as by inquiring of older breeders who have "been there."
When we started breeding PFFF genetics, we bred our first polled female, Miss Tino Unipolled, to Siegfried, a foundation horned FFF bull imported into North America. We crossed the polled females that resulted to other horned genetics to develop not only outcross genetics to our own herd but to increase the performance of the resulting offspring.
The origin and development of our polled herd is outlined below. The largest percentage of animals in our herd are descendants of HFC748J, Miss Tino Unipolled, our foundation polled female. You can click on her name and the names of the other animals named below to view the individual page for the animal. To diversify our genetic base, we added new genetics imported from Germany in 2001 with the addition of Lucy, a polled female out of an Emperor sired female. We have also used Exodus and Brandberg. We purchased Iron Maiden, an older polled female in 2007, from the EDC Pol Magnum 1B line.
Unfortunately, many of the calves that are bred to be polled don’t turn out because of quality or they grow horns. We strictly cull all of the calves that don’t turn out. We have also slaughtered any number of outstanding appearing polled bulls at almost a year because they grew horns or didn’t have performance, conformation, or color that was acceptable to our standards. I sometimes think our standards are too high. We will continue to test breed yearling polled bulls to determine if our newly developed genetics make an improvement. We often put up pictures of the new prospects in the News section or as examples of one of the produce of one of our existing herdsires or donors.
Genetic mutations occur in approximately 1 out of 25,000 calves resulting from horned animals. Polled breeders should be especially vigilant before dehorning and, if there is a doubt, the animal should not be dehorned. It is through the identification of new polled mutations that we can increase the diversity of the available polled genetics to the benefit of the breed.
There appears to be confusion about the process to follow for the breeding of polled Fleckvieh, how the polled traits develop, as well as the percentage of polled offspring that are expected to result from various horned, homozygous polled, and heterozygous polled crossings. There is also confusion about the significance of the scurred gene, as well as whether even a homozygous smooth polled animal may produce a scurred animal, and the scurrs turn into horns. This and more is explained in the attached article first appearing in the August 1998 issue of Simmental Country, titled The Inheritance of Polledness. Click here to read the entire article.
However, there are some items addressed in the article that bear mentioning:
CHANGES: It is our view the most reliable time to inspect an animal for the polled characteristic should be after one year of age. Observations or representations made by a breeder regarding the condition of the animal at a time prior to a year should be viewed with caution because there is a substantial risk that the condition will change. A smooth polled animal at 7 months of age, for example, can grow scurrs and the scurrs can develop into horns in the months and years thereafter. The shape of the skull between the ears is a feature that can aid in predicting the outcome. The flatter the head between the ears, the more likely the animal will develop scurrs or horns. The more peaked or rounded the skull is, the more likely that the animal will continue to be smooth polled or the scurrs won’t grow large. It has been our experience that bull calves are more likely to change than heifers.
ALTERATION: Never modify, remove, or attempt to alter any scurrs or other growth where horns would normally appear on an animal that is not horned. The size and shape of scurrs is important to polled breeders. When any growth has been removed or altered, the animal must be classified as horned and the classification remain until the animal produces a polled offspring when bred to a horned animal. Genetic testing may be available to demonstrate the animal is polled, even after any growth may have been removed.
The definitions of Horned, Polled, scurred and smooth polled adopted by the American Simmental Association in Rule II, Standards for Registration, Section I are inaccurate. As examples, the ASA definition of scurrs does not permit the scurrs to become attached. Scurrs often develop into an attached growth that may resemble a horn but the animal will continue to carry the scurred gene. Smooth polled animals are defined by the ASA as an animal that will never develop scurrs. However, a smooth polled animal will often develop scurrs at a later point. To the extent that the ASA definitions are different than those we have adopted, our definitions apply to animals produced and described by us.
We will continue to emphasize the polled characteristics in our breeding program. Because of the limited variety of quality polled genetics as of the time of the writing of this section, we will continue to breed the occasional horned bull to a polled female and a polled bull to a horned female because of the quality and greater genetic diversity available with horned Fleckvieh.
Some of the breeding goals we set decades ago for our polled herd have been achieved. We have produced performance polled cattle. We have produced calving ease polled cattle. We have produced a variety of polled genetics in our herd that enable us and other polled breeders to cross with them. We have yet to eliminate the scurred genes which may be impossible to accomplish, especially during the time remaining in our lives where we will continue to be engaged as a seedstock producer. We have gotten a good start on one of the remaining goals we established a few years ago which was to produce polled cattle that were also solid colored with as little white on the head as possible. It now appears that this will take several more generations of breeding than we formerly believed before this will be a reliable characteristic.

GENETIC PURITY: All of the animals in our herd are Full Fleckvieh Fullblood genetics. We focus on maintaining genetic purity in our herd in order to maintain the advantages of these genetics. By maintaining this advantage, we are producing animals for a purchaser that will create a greater degree of hybrid vigor than will exist when a purebred, or bred up animal would be used. From our experience, the commercial cow resulting from crossing a Full Fleckvieh Fullblood bull on a female of another breed is better than we have seen from using a purebred or fullblood Simmental. The Fleckvieh commercial cross is the best commercial replacement cow we have seen.
There have been various definitions of the Fleckvieh breed in North America. Some define the breed as Full Fleckvieh Fullblood. Some say 100% Fleckvieh or 100% Full Fleckvieh Fullblood. These have various meanings to various breeders. The definition we use when we say Fleckvieh combines all of these but goes a step farther. Our definition of Fleckvieh requires that all of the animals in the pedigree can be traced only to German or Austrian Fleckvieh genetics. Also, there cannot be any genetics, no matter how remote to the animal, from another breed or grade animal. This cannot be a head in the sand inquiry, but must be a due diligence inquiry. If any reader can identify any animal that we have or use in our herd that does not satisfy this definition, please let us know. Click here to view a recent article entitled "What is a breed?" found in the July 2006 issue of BEEF. See also the description of a Simmental found at the American Simmental Association and the article published by Oklahoma State University, Department of Animal Science, entitled "Breeds of Livestock." www.ansi.okstate.edu/breeds/
Many commercial and seedstock breeders have responded to the unprecedented success of the Angus Breed’s Certified Angus Beef® promotions. As a result, the herds and breeds that weren’t black, such as the Simmental breed, incorporated black Angus genetics in their animals to such an extent that heterosis has been lost. James Gosey, Beef Specialist at the University of Nebraska, Lincoln, wrote that "[t]he extrapolation of logic regarding color has led many beef producers to first make their cattle black, then to work on making their cattle genetically superior in regard to production, carcass merit and reproduction. Producers should not be criticized for this decision, they are simply responding to a market reality. By this response many commercial herds have been drained of nearly all of the hybrid vigor that was once there in their crossbred cows and calves.” Click here to view the article. In the same vein, in an article entitled “Where did all the Breeds go?” Dr. Joe Paschal wrote that a “grading up program reduces hybrid vigor, which is most useful in improving cow adaptability, longevity, fertility, milk production and calf survivability. In effect, the upgrading process reduces productivity of the commercial cow…” Click here to view the article.
Crossbreeding by the use of straight bred bulls on commercial herds increased the productivity of the herd by at least 20%. The use of bulls with a high percentage of genetics in common with the commercial herd won’t anywhere approach this percentage. See “Hybrid vigor making a comeback?” Drover’s March 17, 2008. Click here to view the article.
Clint Peck's article in Beef entiltled, "Guarding Heterosis" supports the concept of using outcross genetics to gain the benefit of heterosis. Click here to view the article. Outcross genetics don’t include genetics that aren’t straight bred animals. The use of fullblood Fleckvieh bulls on the black cattle in the USA will significantly increase the production of these animals and increase the adaptability, longevity, fertility, milk production and calf survivability far more than the use of a black purebred or composite bulls will.
The version of the history of the Fleckvieh breed that is contained in many of the more popular versions is incorrect. The Fleckvieh breed did not originate in Switzerland and then migrate to the other European Countries. The Fleckvieh breed originated in Germany. Starting in the 5th. century, the breed spread from there & Austria and then to other countries, including Switzerland and France.
A newly available, well researched, and authoritative treatise has been published entitled CATTLE BREEDS, AN ENCYCLOPEDIA, authored by Marlene Felius. Rather than do a cut and paste from the pertinent sections of this book, readers are encouraged to purchase this book and learn. It can be found on the internet, including Amazon.com, click here for more information.
This research in this book disproves the popularized version and supports the origin of the Fleckvieh breed being in Germany. The animals that were produced in France and Switzerland, and other European Countries became known as Simmental. Because the early imports into North America came mostly from Switzerland and France, that name continued to be used in North America. However, the advantages of the Fleckvieh animals became recognized, this breed was perpetuated. The Simmental animals were bred mostly to Angus genetics to eliminate the uneconomical genetics of the French and Swiss Simmental cattle and, as a result, Simmental cattle in North America have become recognizeable as predominately black hided cattle.
In other words, the origin of the breed was not in Switzerland, it was in Germany spread from there to other countries.
The Canadian breed magazine Simmental Country, August 2002 issue contained a guest editorial written by Wesley Combs. Mr. Combs was involved in the selection of the early imports from Germany into Canada in the 1970’s. His article deals with the Neff influence but is instructive on the history of the beginning of the Fleckvieh breed in North America. Click here for the article and photos.
TERMINAL AND MATERNAL: There are two extremes. The usual bell curve applies. The terminal cross animal usually has a larger but acceptable birthweight, optimum growth within the frame size desired, as well as a higher yielding carcass that will probably grade average. The maternal type has a lower birth weight, better calving ease, and moderate but acceptable growth characteristics. These two extremes can be identified in the various Fleckvieh genetics. We take these differences into account when planning our long term breeding program, as well as the individual breeding each year. There is a place for each extreme in the breed and for commercial applications.
“Better than 50% of the fed cattle are coming up light in the muscle department,” according to research contained in a February 2005 article in Beef, authored by Wes Ishmael. Click here to view the entire article (.pdf format). The average rib eye in commercial herds is 12.3 square inches. To produce a low percentage of YG 4 steer carcases, with a rib eye average of 14.1, the rib eye of the bull needs to have a yearling ultrasound scan of at lease 15.9 square inches. Only 3% of Angus sires qualify. Only 9% of Simmental sires qualify. We have two Fleckvien herdsires that were ultra sound measured at a year. As you might expect, being sired by Natural, Neutron has a 16.2 square inch rib eye. Evan 440L has a 15.9 square inch rib eye. Both will sire bulls that will add muscle to your calf crop and put money in your account at sale time.
VISUAL APPRAISAL or EPD: We view the Expected Progeny difference figures as but one factor to consider in the breeding or selection process. It is our opinion that a visual evaluation is more important than the epd figures. Breeders should pay more attention to the suggestions outlined in the books and lectures of Jan Bonsma.
An article appearing in the May 2005 issue of the Western Cowman, authored by Heather Smith-Thomas, titled “Computer Cows” May Crash, generally reflects our view of the proper use to be made of the epd figures. Click here to access the article. In sum, the epd figures are only one factor to use in the breeding process.
In the market place of the world, with genetics coming from a number of countries, EPD, EBV and other graphic evaluations are a more important consideration than they otherwise should be. It is not practical or often possible to do a personal inspection or even have someone whose judgment you rely upon make an independent inspection and report to you. Photographs generally don’t disclose many of the traits we look for when making a visual appraisal.
The EPD figures produced and published over the past several years by the American Simmental Association and the Canadian Simmental Association have been inaccurate. In short, the epd for Angus cattle being used to upgrade the purebred Simmentals were incorporated essentially at par from the Angus epd figures into the ASA database while imported cattle were started at zero or some other arbitrarily selected number. This enhanced the Angus genetics and disparaged the Fleckvieh genetics. In 2005, a process was initiated to utilize information from the performance records of other breeds and countries of origin for imported genetics. The results show improvements in the SA influenced genetics but appeared to ignore information on the imported genetics from other countries.
Breeders may wish to refer to the South African Breedplan EBV numbers and compare the SA figures with the ASA figures for commonly used sires. By comparison, you can make your own evaluation of the ranking of these animals as well as get an evaluation of the sires not used in SA. Click here to view the SA figures.
GENETIC TESTING: Starting in the 1980’s, researchers made considerable discoveries in the genetic testing of beef animals with the focus being on the improvement of the carcass, particularly in marbling or quality grade as well as tenderness. Click here to read the article titled “Working Towards a Consistently Tender Steak” written by David Elstein, ARS, appearing originally in the February 2005 issue of Agricultural Research.
The use of these tests should enable the producers to identify genetics that will produce beef cattle that will be move appreciated by the consumer.
When we first wrote this section of our website in 2003, we opined that “[i]t is likely that order buyers, feed lots, and packers in the future will require that their purchases be produced by animals with favorable [genetic testing] results.” See the article titled “Fat Disposition Associated Production Efficiencies & Carcass Value.” The article concludes that the
|
Knowledge generated out of all this research is that different genotypes have phenotypic traits that can be managed to extract the most economic value available to individual animals. Armed with this knowledge feed lot management can be tailored to optimize each genotype of cattle within feedlot groups, all the while maximizing production efficiency.
|
Because cattle with optimal marbling genetics shouldn’t require as many days on feed, producing seedstock with optimal marbling genetics has a real economic value. Click here to read the entire article.
The results of genetic testing have been utilized by the most progressive seedstock producers and are now being utilized by producers of commercial cattle. Click here to read an article reprinted with the permission of DROVERS, May 2007.
There are at present at least three vendors of these tools to beef producers. MMI Genomics, Igenity and GeneSTAR, marketed in North America through Bovigen, seem to provide comparable services. Their programs are explained on their respective websites. We started with GeneSTAR and continue to utilize this program to develop herdsires as well as females to utilize in a transplanting program. We expect that the research will continue in this area that will result in improvements in the existing testing and additional tests so that all producers can breed a better and more consistent product.
(Updated on 9/15/07)
In early 2009 we learned that Pfizer acquired Bovigen and the GeneSTAR program. Much information is provided on its website so there is no need to repeat it here. Here is the link: http://www.pfizeranimalgenetics.com/pdf/US%20Detailer%203-6-09%20FINAL.pdf
In sum, Pfizer now tests for a panel of 56 DNA markers to predict an animal’s genetic potential for feed efficiency, marbling and tenderness. It is called MVP for Molecular Value Prediction. Because of the increased number of markers, the star system previously utilized became unworkable. However, the test results for a particular animal are now expressed in numbers and are compared to the entire population of all breeds. There is no breed specific comparison for Fleckvieh. Pfizer requires that a minimum of 500 test animals from one breed be available to make an inbreed comparison and there are presently not enough animals for the Fleckvieh breed for a statistically significant sampling.
(Updated on 6/22/09)
In the ever changing environment of genetic testing, we read with great interest an article appearing in BEEF by Alison Van Eenennaam titled “Do DNA Tests Work?” Click here to read the full article (this link is currently unavailable). Two highlighted portions of the text caught my eye, causing me to study the entire article. “The predictive value of a DNA test decreases when markers are incorrectly associated with the trait of interest in a given breed or animal.” And, more significantly, “[a] criticism of the currently available tests is that their ability to predict genetic merit is limited.”
We were previously a strong proponent of genetic testing as the foregoing section of this website demonstrates. We justified the expenditure because what little information the test results provided were better than nothing and were a valuable tool to us in selecting animals for future breeding. However, we became disillusioned with the concept some time ago because of the ever increasing number of upgrades and the resulting upgrade cost to the producer.
The Eenenaam article conclusions have further solidified my decision not to engage in any further genetic testing until there is significant improvement in the protocol and verification methods. To use an historical quotation, “the game is not worth the candle.” We will leave the out of date test results that appear on some of the animals on our website but will not be adding more until we become convinced that the game is worth the candle.

TEMPERAMENT: The Fleckvieh breed is very docile from our experience.
Temperament is a very important factor for a breeder of seedstock to consider when developing a breeding program. Not only are ill tempered cattle dangerous to humans, but they don’t grade well, are difficult to keep in good flesh, and are prone to illness and injury. Accordingly, there is a sound economic reason to produce gentle cattle.
The temperament of a particular animal or group of animals is based upon he-editary and environmental factors. Breeders can control both by the proper selection of a bull and by regulating how the herd is handled. Environmental considerations are well known as they bear on temperament. If your cows are roughly treated, by the use of an electric prod, run on horseback, beat while in a crowding alley, or chased with dogs, they are going to be wild and unpredictable around humans. A badly treated and wild cow will teach her calf to act the same way. It may take a little longer to move a gentle animal the direction you want the animal to go but the wait is well worth it.
Temperament is also greatly influenced by genetics and there is a high degree of heritability. Some bloodlines that are in use in North America and elsewhere that are predisposed to being ill tempered have been identified in communications between breeders that have had the experiences.
When I first wrote the various sections of this part of our website, I didn’t include temperament as a breeding goal. We didn’t have ill tempered cattle in our Fleckvieh herd so I didn’t recognize that this was a problem. However, the issue has now surfaced in various discussion groups, I think in part prompted by the influx of different genetic lines imported from South Africa into North America. The only information the importers of SA embryos and semen had was what was disclosed through the marketing efforts of the exporters and, in turn, the NA importers. Now that a bank of experience has developed and is being shared, the issue of temperament has risen to a higher level of recognition.
What follows is an incomplete list that has been assembled by our own experience and the communicated experiences of others. Anecdotal information is subjective and often demonstrated to be incorrect but it does bear mentioning.
- Bar 5 Big Deutsche: The offspring of this bull have been described as wild and unpredictable.
- Siegfried: There is no consensus on this bull. Some assert that the offspring of Siegfried, such as 809G and Image, produce wild offspring. Others state that they don’t have any such problems and the cattle are generally docile. We have used Siegfried and have not noticed that his offspring are ill tempered and, indeed, are quite docile.
- Bold: There does not appear to be a dissenting vote on the ill tempered nature of Bold offspring and that the trait stays with the cattle where he may be a ways back in the pedigree.
- Canadian Neff: Some of these offspring are rank but not enough to make this a genetic trait for this line according to the information provided.
- While the subject of some dispute, there are some lines of SA animals that are prone to being ill tempered according to a few breeders with a little experience. However, I don’t think anyone in NA knows enough about these genetics to form a reliable opinion on this trait.
If you have identified other bloodlines or particular sires that have a mean streak, or disagree with what is written here, please let me know.
Finally, I would be remiss unless I reminded breeders that it is the gentle animal that gets you. Never put yourself in harms way. Always have an escape route.
Since writing the above, an article titled “Methods to Evaluate Temperament in Beef Cattle” authored by Reinaldo F. Cooke, appeared in the October issue of the OREGON BEEF PRODUCER. This article is well worth reading and can be accessed by clicking here.
