Abstract: 368 backcross progeny from crosses between two Bos taurus breeds (Limousin and Jersey) used to study the effects of IGF1 genotypes on meat weight, tenderness and muscle hypertrophy. The results revealed that single nucleotide polymorphisms (SNPs) in the IGF1 gene were associated with carcass weight and meat weight but not tenderness as measured by shear force. Interestingly, the IGF1 SNPs were not associated with meat percentage or fibre diameter, suggesting the gene affects growth in general rather than muscle hypertrophy specifically.
