Abstract
The expansion of the dairy herd, along with enhanced fertility in dairy cows, and increased adoption of sexed semen technologies, has resulted in a growing number of beef cattle originating from the dairy sector. Breeding programs in dairy cows have been primarily focused on improving fertility and milk production, with limited attention given to progeny intended for beef production. To establish a sustainable dairy and beef sector, enhancing the performance and efficiency of beef calves from dairy herds is crucial. This thesis aims to assess how current breeding strategies in Irish dairy farming impact downstream beef merit. The thesis will investigate genetic and phenotypic trends for various traits in both dairy and beef cattle. The relationship between traits in dairy breeding objectives, such as cow liveweight and carcass traits, will be evaluated to help direct future breeding objectives. The findings will inform future dairy breeding strategies to ensure environmental and economic sustainability across dairy and beef systems.
