Simple Summary Cow–calf production is the foundation of the US beef industry. However,
infertility and sub-fertility limit its sustainability. In this review, we discuss the progress made …

This study estimated the heritabilities (h2) and genetic and phenotypic correlations between
reproductive traits, including calving interval (CI), age at first calving (AFC), gestation length …

Simple Summary Calving interval data by the National Association of Hungarian Holstein
Friesian Breeders in Hungary were processed. According to our results the relatively low …

Reducing age at first calving (AFC) has been a challenge in beef herds. There is anecdotal
evidence that herd owners choose to calve heifers older because of the perceived …

Background Conducting genome-wide association studies (GWAS) for reproductive traits in
Hanwoo cattle, including age at first calving (AFC), calving interval (CI), gestation length …

Age at first calving (AFC) represents the nonproductive period of∼ 2 yr in Holstein cows,
and thus, it has a relevant effect on the cost of rearing replacements in the dairy herd. In the …

Objective This study aims to investigate the genetic structure and characteristics of the
Angus cattle population in Hungary. The survey was performed with the assistance of the …

Simple Summary An important element of livestock breeding is the selection that leads to the
consolidation and improvement of the traits with utility value. The use of single-nucleotide …

Angus HeiferSELECT is a genomic tool designed to inform the selection of replacement
heifers by providing genomic estimated breeding values (GEBV) for traits related to cow-calf …

This study aimed to examine the age at first calving (AFC) in Hungarian Angus herds. This
study was conducted on the basis of data from 2955 registered cows, classified into five …
