By: Al Kuck, Vice President, Beef Programs DNA marker technology has been advancing rapidly since the first markers were discovered in 1989. GeneSTAR ® was first introduced in 2000 as a single marker test for marbling. In 2004 GeneSTAR Born: introduced three more marbling and Yrlg. three Frame: tenderness markers, Birth Weight: in 2006 four feed efficiency markers Mature were Frame: incorporated. Rankings 205 Days: were expressed as stars which indicated Scrotal: the presence or absence 365 Days: of the desirable gene. In this Beef Genetic Tattoo: Management Guide Mature: you will find Molecular Value Predictions Calving Ease (MVPs) Rating: listed under Owned each By: bull. It is the next logical iteration of genetic marker These Molecular Value Predictions are a significant improvement over the star system previously used by GeneSTAR. It is a more powerful tool because it provides direct information on the expectations when using a sire. It will be most valuable on animals that do not have a progeny proof or with relatively little progeny performance data. In our listings within the Beef Genetic Management Guide, we are also providing “percentile rankings” which indicate how the animal ranks within the respective breed. As an example, an animal in the 10th percentile would be better than 90% of the breed. selection. These predictions for feed efficiency, marbling and tenderness include the original 11 validated markers plus an additional 45 markers. The development of GeneSTAR MVPs followed a four step process: 1. Discovery - identify panels of markers that are significantly correlated with one or more cattle groups with data for commercially important traits. 2. Statistical methods - incorporate individual markers into larger marker panels to develop the MVP values. 3. Evaluation - each marker panel is evaluated in separate cattle groups to see if it predicts the trait as well as it does in the original discovery population. 4. Third Party Validation - the National Beef Cattle Evaluation Consortium acts as a third-party agency to validate DNA marker technology Trait Definition Units Feed Efficiency2 Marbling3 Feed Efficiency Marbling Tenderness 1.03 -0.2 -0.38 100% 100% 30% Difference between an animal’s actual and expected feed intake based on its body weight and growth rate Degree of intramuscular fatness in the longissimus dorsi (ribeye) muscle lbs./day Marbling Score 0 – 9 MVP Range* Min: -3.17 Max: 2.38 Min: -1.00 Max: 1.11 While these new GeneSTAR MPVs are a much more useful tool, it is only the beginning of much bigger programs to come from Pfizer Animal Genetics. Cattle producers will have access to a new suite of traits in 2010. This will come with the first commercial genomic predictions based on the high density BovineSNP50 chip. This chip will look at 50,000 individual SNP markers scattered throughout the cattle genome to predict a wide variety of traits. This very large panel of markers will yield much higher levels of accuracy of prediction. Validation studies are now underway and we would expect to have the test available in early 2010. The information will continue to be delivered using the MVP platform. Some of these will enhance the reliability of traditional EPD traits that we are all familiar with. Other MPVs will be for traits that are expensive and difficult to measure, and likely beyond the scope of most breeders to measure, yet are economically important. Average % Reliability 30% 26% We believe this new technology will be useful for producers in both the commercial and seedstock arenas. The commercial producer can identify his top production cows, and they can be bred with female-sorted semen to provide future replacements. The remainder can be bred to malesorted semen to provide a higher percentage of steers, taking advantage of the price differential. The seedstock producer can put top ranking animals into flushing programs, or breed top cows to male or female-sorted semen, depending on the needs of his customers. The remainder can be utilized as recipients or bred to a male-sorted terminal sire. Tenderness Force required to shear a cooked steak after postmortem aging W-B Shear Force (lbs.)
