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 …

Beef cattle breeds consist of three major genetic subdivisions. The taurine group is adapted
to temperate environments, and the zebu and Sanga groups are both adapted to tropical …

Recent reports identified DGAT1 (EC 2.3. 1.20) harboring a lysine to alanine substitution
(K232A) as a candidate gene with a strong effect on milk production traits. Our objective was …

Aberdeen Angus beef cattle from the Brazilian herd were studied genetically using
restriction fragment length polymorphism (RFLP) of the kappa-casein-HinfI (CSN3-HinfI) …

The objective of this study was to determine the allele and genotype frequencies of genetic
variants in five milk protein genes and estimate the effect of these variants on milk yield in …

The objective of this study was to investigate the effects of bovine GH1, CAPN1 and CAST
gene polymorphisms on carcass and meat traits in Nellore and Nellore x Bos taurus beef …

Point mutations in exon IV of the bovine κ-casein (CSN3) gene determine two allelic
variants, A and B. These variants were distinguished by polymerase chain reaction and …

Background Improvement of efficiency and economic returns is an important goal in dairy
farming, as in any agricultural enterprise. The primary goal of dairy industry has been to …

The objectives of the present study were to estimate the allele and genotype frequencies of
the GH1/Alu I and POU1F1/Hinf I polymorphisms in beef cattle belonging to different genetic …

Four cattle breeds (Gyr, Nellore, Guzerat and Holstein) were analyzed by amplification of
genomic DNA using microsatellite loci to evaluate the genetic diversity within and among …
