HERITABILITY AND REPEATABILITY ESTIMATES OF FIRST SERVICE CONCEPTION AND FIRST CYCLE CALVING IN ANGUS CATTLE
Described as the ability of an individual to conceive and remain pregnant, fertility remains one of the largest economic impacts on cattle producers. Infertility and(or) sub-fertility in the cow herd can result in financial losses due to a reduction in calf crop, lower quality calves, and increased breeding and replacement costs. Improving reproductive efficiency via altered management and selection could prove useful for cattle managers to minimize these costs while increasing genetic gain and income. However, historically the investigation of fertility traits has been minimal due to the binary ...
