Association of leptin genotypes with beef cattle characteristics

A single nucleotide polymorphism (C/T) in bovine leptin, resulting in an arginine to cysteine amino acid substitution (p.Arg25Cys), has previously been shown to have an impact on carcass characteristics. Given the significant energetic relationship between fat and animal efficiency, further evaluation of this SNP across larger animal populations is warranted. Of the total number of 136 similar to 286 genotyped cattle in this study, 92 similar to 112 and 53 similar to 189 were analysed for backfat and body weight measurements, respectively. Results showed a significant positive relationship (P similar to
