Genetic polymorphism of the kappa-casein gene in Brazilian cattle
“Genetic polymorphism of the kappa-casein gene in Brazilian cattle”, vol. 7, pp. 623-630, 2008.,
Frequencies of κ-casein gene alleles were determined in 1316 animals from the Brazilian Bos indicus genetic groups (Sindhi cows, Gyr sires, Gyr cows, Guzerat sires, Guzerat cows, Nellore sires, and Gyr x Holstein crossbreds) by means of polymerase chain reaction-restriction fragment length polymorphism analysis using two independent restriction nucleases (Hinf I and HaeIII). The genotyping of κ-casein alleles (A and B) is of practical importance, since the B allele is found to correlate with commercially valuable parameters of cheese yielding efficiency.
