Since domestication, significant genetic improvement has been achieved for many traits of
commercial importance in cattle, including adaptation, appearance and production. In …

Age at first calving (AFC) plays an important role in the economic efficiency of beef cattle
production. This trait can be affected by a combination of genetic and environmental factors …

We compared the outcome of mating programs based on different evaluation models that
included nonadditive genetic effects (dominance and heterozygosity) in addition to additive …

Despite the importance of fertility in humans and livestock, there has been little success
dissecting the genetic basis of fertility. Our hypothesis was that genes differentially …

We performed a genome‐wide mapping for the age at first calving (AFC) with the goal of
annotating candidate genes that regulate fertility in Nellore cattle. Phenotypic data from 762 …

Simple Summary Runs of homozygosity (ROH) are continuous homozygous regions that
generally exist in the DNA sequence of diploid organisms. Identifications of ROH leading to …

Zebu animals (Bos indicus) are known to take longer to reach puberty compared with taurine
animals (Bos taurus), limiting the supply of animals for harvest or breeding and impacting …

Holstein Friesian cow training sets were created according to disease incidences. The
different datasets were used to investigate the impact of random forest (RF) and genomic …

Background Reproduction is a key feature of the sustainability of a species and thus
represents an important component in livestock genetic improvement programs. Most …

Reproductive traits, such as the number of teats and litter size, are essential for animal
breeding programs due to the importance of the production chain, since they influence the …
