The Center for Genetic Improvement of Livestock (CGIL)
This Center was formed on July 1, 1992 through the support of the COEP. Research in the Center includes:
- Characterization of the callipyge trait in sheep. Animals carrying one copy of the callipyge gene have about 8% more muscle, 8% less fat and 2% less bone than flock mates not carrying the gene. Interestingly, this increase in muscle mass is almost exclusively in the hind limb and the loin of the animal. These improvements in muscle mass significantly affect retail yield and the percentage of carcass weight found within the high-priced lamb cuts.
- Identification of a genetic marker for the callipyge gene. A genetic marker for this locus has been identified by Dr. Noelle Cockett, a researcher within the Center. A genetic test using these markers is about 97% accurate in determining an animal's genotype for the heavy muscling gene. Development of a commercially available genetic marker test is ongoing.
- Embryo cloning of callipyge animals. Once superior callipyge animals are identified using the Center's genetic markers, they will be rapidly multiplied using embryo cloning techniques, as directed by Dr. Ken White. Combining genetic technologies of genetic markers and embryo cloning will allow the Center to provide Utah sheep producers with animals that produce meat more efficiently and have desirable carcass characteristics.
Director of the CGIL is Noelle E. Cockett of the ADVS Department.
Co-principal Investigator is Kenneth L. White.
