‘Stress reduces the resistance of cows, causing the likelihood of infections to increase. And the number of stress moments is quite high actually; cows are like people with autism, they do not handle changes well.’ Speaking is Arnout Dekker, a practicing veterinarian with years of experience who now works at Phibro, the supplier of OmniGen, the product that offers proven support to the immune system of, among others, dairy cows, and thus maintains a high resistance level. In turn this results in fewer cases of disease and reduced use of antibiotics.
