Plasma anti-Müllerian hormone as a predictive endocrine marker to select (Holstein) and (Nelore) calves for embryo production

This study evaluated the association between plasma anti-Müllerian hormone (AMH) concentrations and in vitro embryo production (IVEP) in Bos indicus (Nelore; Experiment 1) and Bos taurus (Holstein; Experiment 2) calves superstimulated or not with 140 mg of porcine follicle-stimulating hormone (pFSH; four decreasing doses twice daily). Oocytes were recovered from calves aged 2 to 4 mo after receiving gonadotropin stimulation (Nelore: n=15; Holstein: n=12) or not (Nelore: n=15; Holstein: n=12). Cycling heifers formed a positive control group [n=15 for Nelore (aged 18 to 24 mo); n=10 for Holstein (aged 14 to 16 mo)].
