Excellent reproductive performance in both males and females is fundamental to profitable
dairy and beef production systems. In this review we undertook a meta-analysis of genetic …

Fertility is a complex trait in beef production systems and genetic evaluation procedures,
which is partly due to the numerous measures used to assess reproduction. Beyond beef …

In the present study, records on 115,291 heifers distributed in 113 herds were used to
investigate the association between age at the first calving (AFC) and lactation performance …

Due primarily to a lack of phenotypic data, little research has been undertaken on the
genetics of reproductive performance in beef cattle. The objective of this study was to …

Bovine and buffalo are important livestock species that have contributed to human lives for
more than 1000 years. Improving fertility is very important to reduce the cost of production. In …

This study was carried out to estimate the heritability and genetic correlations between
adjusted weights at 210 (W210) and 450 (W450) days of age, scrotal circumference …

Some dairy cattle breeders believe that dairy cows with high pin bones will have poorer
fertility. The aim of this study was to examine this claim by investigating the relationships …

Simple Summary Reproductive performance of beef cows affects the profitability of beef
production systems. Heritability of fertility traits is generally low, which means that there is a …

Measures of heifer fertility are economically relevant traits for beef production systems and
knowledge of candidate genes could be incorporated into future genomic selection …

The aim of this paper was to estimate direct and maternal genetic parameters for calving
ease (CE), birth weight (BrW), weaning weight (WW), and calving interval (CI) to assess the …
