Heifer conception rate (HCR) is defined as the percentage of inseminated heifers that
become pregnant at each service. The genome-wide association analyses in this study …

Age at puberty is an important component of reproductive performance in beef cattle
production systems. Brahman cattle are typically late-pubertal relative to Bos taurus cattle …

The aim of this study was to identify SNP markers that associate with variation in beef heifer
reproduction and performance of their calves. A genome-wide association study was …

A genome-wide association study (GWAS) of the daughter pregnancy rate (DPR), cow
conception rate (CCR), and heifer conception rate (HCR) using 1,001,374–1,194,736 first …

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 …

Fertility plays a key role in the success of calf production, but there is evidence that
reproductive efficiency in beef cattle has decreased during the past half-century worldwide …

Reproduction efficiency is a major factor in the profitability of the beef cattle industry.
Genomic selection (GS) is a promising tool that may improve the predictive accuracy and …

Background Beef cattle breeding programs in Brazil have placed greater emphasis on the
genomic study of reproductive traits of males and females due to their economic importance …

Background Achieving rapid genetic progress while maintaining adequate genetic diversity
is one of the main challenges facing the dairy industry. The increase in inbreeding can be …

Harsh tropical environments impose serious challenges on poorly adapted species. In beef
cattle, tropical adaptation in the form of temperature and disease resistance, coupled with …
