Nutrition is of fundamental importance in reproductive function of female beef cattle. Nutrition
determines live weight (LW) and body condition score (BCs) and both were found more than …

Background Thousands of years of natural and artificial selection have resulted in
indigenous cattle breeds that are well-adapted to the environmental challenges of their local …

A current challenge in genetic improvement of cattle is to identify genomic selection
strategies that could work across breeds. Breed differences, scarcity of data, and lack of …

Age at puberty in beef heifers can influence economic efficiency of beef production through
effects on both age at first calving (2 vs. 3+ years of age) and the time of conception of …

The fertility of young bulls impacts on reproduction rates, farm profit and the rate of genetic
progress in beef herds. Cattle researchers and industry therefore routinely collect data on …

Understanding the genetic architecture of beef cattle growth cannot be limited simply to the
genome-wide association study (GWAS) for body weight at any specific ages, but should be …

Nelore heifers usually begin their reproductive life at⩾ 24 months of age mainly due to
suboptimal nutritional conditions and genetics. This study aimed to determine the effect of …

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 …

The identification of biological processes related to the regulation of complex traits is a
difficult task. Commonly, complex traits are regulated through a multitude of genes …

Background An important goal of Zebu breeding programs is to improve reproductive
performance. A major problem faced with the genetic improvement of reproductive traits is …
