Patent ID: 8003318

Claim:
A method for identifying a bovine animal having a higher average daily gain (ADG), a higher final weight (FW), a higher dry matter intake (DMI), a higher metabolic mid-weight (MMW), a higher slaughter weight (SW), and a higher loin muscle area (LMA), as compared to a general population of bovine animals, comprising the steps of: (a) obtaining a biological sample from said bovine animal, wherein the sample comprises nucleic acids comprising the bovine growth hormone receptor (GHR) gene; (b) detecting in said nucleic acids the presence of a single nucleotide polymorphism (SNP) in the GHR gene, wherein the SNP is a G in both alleles of the GHR gene at the position corresponding to position 300 of SEQ ID NO: 1; and (c) correlating the G in both alleles of the GHR gene to higher ADG, FW, DMI, MMW, SW, and LMA, thereby identifying said bovine animal.
