Impact of age at first calving on performance traits in Irish beef herds.

Journal of animal science - 3 Jan 2023

Twomey Alan J, Cromie Andrew R

Abstract excerpt

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 consequences of calving heifers at 24 mo of age compared to 36 mo on performance traits in beef herds. The objective of this study was to estimate the association of calving heifers at younger ages on subsequent performance traits, calving...
