Casein (CSN) gene variants and parity affect the milk protein traits in crossbred (Bos taurus x Bos indicus) cows in sub-tropical climate
Genotypes at four casein (CSN) loci—A26181G of CSN1S1, C6227T of CSN1S2, A8101C of CSN2, and A13104C of CSN3—along with non-genetic factors were studied for their effects on various milk protein traits in 100 crossbred cows with major inheritance of Holstein Frisian ( Bos taurus ) and Tharparkar ( B...

Zusammenfassung: | Genotypes at four casein (CSN) loci—A26181G of CSN1S1, C6227T of CSN1S2, A8101C of CSN2, and A13104C of CSN3—along with non-genetic factors were studied for their effects on various milk protein traits in 100 crossbred cows with major inheritance of Holstein Frisian (
Bos taurus
) and Tharparkar (
Bos indicus
). Results demonstrated the presence of all CSN genotypes with a predominance of heterozygotes. At CSN2 (A8101C; His67Pro) locus, the A2 allele, desirable for human health, was present in 62% as heterozygous and 29% in homozygous condition. Among non-genetic factors, parity of the cows had a significant influence on the milk protein traits in these crossbreds. The genotypes at CSN1S1, CSN2, and CSN3 loci were found to influence (
