1. Causes Feed Nutrition Level: Dairy cows consume too much or too little energy during the perinatal period, which will cause postpartum estrus but also lead to a reduction in the fertility rate. When dairy cows are fed a diet containing low levels of protein, their fecundity will decline, while higher levels of protein, i.e. […]
Over-feeding density limits feeding space and rest space, which hurts rumination time. By ensuring that dairy cows maintain adequate nutritional intake to meet their needs, we can safeguard health and improve milk production. Therefore, the precise formulation and a high-quality diet are indispensable. Unfortunately, dairy cows do not always get the most nutritional value of […]
