Abstract
Anti-Mullerian hormone (AMH) is considered a biomarker of ovarian follicular reserve and fertility in humans and farm animals. A study was carried out to evaluate the peripheral AMH concentration in high and low fertile crossbred cows. Vrindavani crossbred cows (n=60) at the institutional dairy farm were used for the study. The age-specific decline in AMH concentration was evident, with the highest concentration at 4-6 years (134.8±17.74 pg/mL) corresponding to second to third parity. Retrospective assessment of fertility using 217 lactation records in crossbred cows revealed that circulatory AMH was higher by 69 pg/mL in the high fertile cows than those of low fertile cows. It was concluded that the serum AMH concentration was influenced by age and parity. Further, serum AMH concentrations were found to be higher in the group of cows that had superior fertility records in comparison to the group with low-performing animals.
