Abstract The objective of this work was to estimate the frequency of favorable genotypes in the gene markers CAPN1 316, CAPN1 4751, CAPN3, and CAST c.2832 in Brazilian Brahman cattle. A total of 108 DNA samples from purebred Brahman cattle were analyzed to genotype the animals for each marker through polymerase chain reaction and direct Sanger sequencing. These samples were originated from 54 bulls and 54 cows used as semen and oocyte donors, respectively. The genotype frequencies, known to be associated with meat tenderness, were 48% AA in CAST and 14% GG in CAPN3. CAST has been used in the selection of animals with a meat tenderness phenotype across various cattle breeds, including Brahman cattle from other countries. The CC genotype, which is favorable in CAPN1 316 and CAPN1 4751, was not identified in the analyzed samples. The highest prevalence of the AA genotype in CAST observed in bulls and cows used in purebred breeding programs in Brazil indicates that this marker can be used to guide mating strategies in order to increase the frequency of this genotype and enhance meat tenderness.
The Charolais sheep is a world‐renowned breed of meat sheep, known for its large frame, heavy muscling, and rapid growth. A novel breed, the Chao Mu meat sheep, has been developed by utilizing the Charolais sheep as the paternal line. This advancement has significantly contributed to the genetic enhancement and breedin...

The study aimed to evaluate the association of SLCO2B1 gene polymorphisms with live weight in Manych Merino rams. Genotyping was performed using whole-genome sequencing (NovaSeq 6000) of 30 clinically healthy nine-month-old rams, randomly selected from three unrelated lines (relatedness coefficient ≤0.5). Mapping to th...
