Genome-wide association studies (GWAS) are employed to identify genomic regions and candidate genes associated with several traits. The aim of this study was to perform a GWAS to identify causative variants and genes associated with milk yield, frame, and udder conformation traits in Gir dairy cattle. Body conformation traits were classified as "frame," and "udder" traits for this study. …
The Gyr breed and its crosses are unquestionably a consolidated genetic material, being the base along with the other zebu breeds, for the support of the cattle raising of tropical and subtropical countries like Brazil, Colombia, Mexico, Peru, Venezuela. The productive and reproductive potentials of the animals are expressed only to the extent that their environmental conditions allow. Th…
In general, Brazilian beef herds need to improve their indexes of efficiency and the final product (meat) quality. Moreover, nowadays, there is a worldwide concern about the animal production sustainability, which could be improved selecting animals with decreased enteric methane emission to the atmosphere. With the evolution of the complete genome sequencing and the decreasing sequencing…

Inbreeding in dairy cattle increases homozygosity, favoring the expression of deleterious recessive alleles and resulting in the phenomenon of inbreeding depression, which can compromise the productive and reproductive performance of animals, affecting important characteristics of economic interest to breeders. This research aims to estimate the inbreeding coefficients of Holstein and Jer…
The objective of this study is to estimate the genetic parameters, correlations, and trends of morphometric and dynamic traits in the Mangalarga horse breed. Various databases will be analyzed, including a file of scores and measurements from the definitive registry, containing 1,346,049 scores for morphometric and dynamic traits, obtained between 1977 and 2019, and belonging to 65,101 an…
Research into meat and carcass quality in Nelore cattle is still limited and challenging, as these traits are polygenic and difficult to measure. Several candidate genes, such as DGAT1, CAPN5, TG and MADH3, have previously been associated with meat quality in taurine breeds. Identifying these genes and estimating their allelic (fa) and genotypic (fg) frequencies in the Nelore breed will p…
The high production and export of beef cattle in Brazil resulted in an increasing number of feedlot-finished animals within the national territory and allowed the country to occupy a prominent position in the meat market worldwide. However, the high cost of feed still represents one of the biggest expenses in feedlots. Feed efficiency is directly related to the increase in meat production…
Babesiosis is a disease caused by the tick Rhipicephalus microplus that has a serious impact on the beef cattle industry in Brazil. Knowing the association of your incidence and feed efficiency, a relevant parameter for bull selection, it can be of great importance to improve the indices of production. However, the effect of the association of these two parameters has not yet been verifie…

As características reprodutivas são de extrema importância como objetivo de seleção, no entanto, não tem sido considerada amplamente em programas de melhoramento genético. Em parte por tratar-se de características categóricas, que não apresentam expressão fenotípica contínua. Entre estas podem ser citadas probabilidade de prenhez aos 14 meses, probabilidade de reconcepção e habilidade de …
