Use Of Anti-Mullerian Hormone To Select For Fertility In Beef Heifers, Hannah Newberry
Animal Science Undergraduate Honors Theses
ABSTRACT
A study was conducted to determine whether concentration of serum Anti-Mullerian Hormone (AMH) at weaning and/or breeding could predict subsequent fertility in beef heifers. Frequency distribution was used to assign serum AMH concentration measured at weaning, breeding, and the change from weaning to breeding, into quartiles. Comparison of heifers based on serum AMH quartiles at weaning failed (P ³ 0.35) to detect any effect of AMH on subsequent heifer cyclicity at breeding, estrous response after synchronization, artificial insemination (AI) pregnancy rate, overall breeding season pregnancy rate, or estimated estrous cycle of the breeding season when conception occurred. Based on …
