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 …

Background Birth weight (BW) is an economically important trait in beef cattle, and is
associated with growth-and stature-related traits and calving difficulty. One region of the …

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 …

A total of 22 quantitative trait loci (QTL) were detected on 19 chromosomes for direct and
maternal calving traits in cattle using a genome-wide association study. Calving …

In this study, a 3-trait linear model was used to obtain genetic parameters for direct and
maternal components of calving ease (CE), gestation length (GEST), and birth weight (BWT) …

Simple Summary Hanwoo cattle is considered one of the most economically important
species and sources of nutrition for Koreans. Thus, both the reproductive performance and …

Cow milk yield is a critical component for the growth of the calves in the preweaning period.
The genetic correlation between direct weaning weight and milk yield traits may cause a …

Background Body weight (BW) at different ages are of increasing importance in dairy cattle
breeding schemes, because of their strong correlation with energy efficiency traits, and their …

With regard to potential applications of genomic selection in small numbered breeds, we
evaluated genomic models and focused on potential candidate gene annotations for weight …

The aim of this paper was to estimate the genetic relationships among calving ease (CE),
calf survival (CS), and gestation length (GL) to assess the possibility of including this …
