Check out our last results with the Bull 4MID® Kits to evaluate sperm quality and fertility in Holstein bulls! These results were presented in Gramado (Brazil) during the last CBRA Meeting in May 2019.

In this large study, the proAKAP4 concentration was shown to be a pertinent new sperm parameter to predict bull fertility in a field setting of more of 190000 IA. 

These results will be published soon!
