Antral Follicular Count Is A Tool That May Allow The Selection Of More Precocious Bradford Heifers At Weaning, R. Santa Cruz, R. A. Cushman, C. Viñoles
Roman L. Hruska U.S. Meat Animal Research Center: Reports
Although antral follicle count is a repeatable parameter across life that is positively associated with fertility, its use at weaning as a tool to discard less fertile heifers has not been extensively evaluated. The hypotheses of this work are: 1) maximum antral follicle count (MAFC) is repeatable between weaning and pre breeding evaluations, allowing selection of more fertile heifers at an early age, 2) heifers with high MAFC have growth and development parameters linked to an earlier puberty and pregnancy, 3) MAFC has a positive correlation with AMH concentrations, so that both could be used inter changeably. In this study, …
