Abstract: The present invention provides compositions and methods for genotyping bovines including dairy cows and beef cattle More particularly, the invention is directed to single nucleotide polymorphisms in Stearoyl-CoA-Desaturase 5 (SCD5) Sterol regulatory element-binding protein-1 (SREBP1). SREBP cleavage-activating protein (SCAP), Insulin induced protein 1 (INS1G1). Insulin induced protein 2 (INS1G2) and Signal recognition particle receptor (SRPR) associated with fatty acid composition of bovine meat and milk.

Abstract: The present invention provides for selection of livestock animals, including bovines, whose genotypes based in the STAT6 gene are correlated with phenotypes reflecting desirable carcass and feedlot traits. These phenotypes include back fat (BFAT), calculated yield grade (CALCYG), cutability (CUT), hot carcass weight (HCW), dry matter intake (DMI), days on feed (DOF), back fat rate (BFAT RATE) and average daily gain (ADG), based on the knowledge of the STAT6 genotypes. The predictive value is based in part on the discovery that certain single nucleotide polymorphisms (SNPs) within the STAT6 gene are linked to phenotypes of economically these important carcass and feedlot traits. Also provided are SNPs within the STAT6 gene useful in reliably distinguishing between a Bos taurus and a Bos indicus bovine.

Abstract: A mouse cDNA is illustrated by FIG. 3 (SEQ ID NO:1) which, when knocked out or prevented from expression, results in high growth. This mouse cDNA is highly homologous to genes of other species, such as human and cattle.

Abstract: This invention pertains to the discovery of a gene, reduced expression of which results in a high growth (hg) phenotype. This invention pertains to knockout animals displaying such a high growth phenotype and to methods of screening for agents that modulate a high growth phenotype.
