University research has shown that the stronger the intensity of a cow’s estrous (heat), the better chance she has of holding her pregnancy.

These findings could help New Zealand dairy farmers improve the fertility of their herd by having a heat detection plan in place to ensure animals are put up for AI when their estrous intensity is at its strongest.

Join Rosanna Dickson as she chats with Dr Ky Pohler from Texas A&M University about his findings and how New Zealand farmers can ensure they are mating their cows at the right time.
