During the grazing season the cows receive a high energy content ration in the barn. In the winter time the ration contains even levels of protein and energy.For us, it is important to have cows with good longevity and a good health index. We do not prefer cows with a very high milk yield, because these types of animals often need a lot of maize in their diet, which is an extra cost as we need to purchase it in. We prefer cows with a low lactation curve,” he added.
