Bovine AMH Testing

A biomarker selection tool for replacement heifer management for dairy and beef producers

Anti-Müllerian Hormone (AMH) is a protein hormone produced by granulosa cells in growing ovarian follicles. AMH can be measured any time in the estrous cycle and is a direct measure of ovarian reserve and has a high correlation to Antral Follicle Count (AFC). Declining AMH levels have been correlated to decline in fertility/fecundity in several species. In human IVF clinics, AMH levels are used to predict the size of a woman’s ovarian reserve and her likelihood of producing viable eggs upon ovarian stimulation. AMH testing has been used very successfully in human IVF clinics. Similarly, bovine AMH levels can be used to select a dairy or beef cattle herd with greater fertility/fecundity.

In dairy and beef cattle, measuring AMH will:

– Enable the selection of the best heifers that will produce the highest number of transferable embryos

– Identify high producing embryo transfer donors for AI programs

– Identify cows with higher AI pregnancy rates

– Monitor the reproductive performance of cows

– Identify cows with higher first-conception service rates and fewer service requirements


The Ansh Labs Bovine AMH test has been validated in the following breeds:

Bos taurus: Jersey, Hereford, Holstein, Angus, Red Angus, Black Angus

Bos indicus: Brahman, Gyr, Nelore

Bubalus bubalis: Murrah

Mixed: Beefmaster, Brangus, Holstein-Jersey, Braford, Bonsmara, Wagyu
