Feeding high-yielding dairy cows is a sensitive process that requires special care. During the last 15–20 days before calving, the appetite of pregnant dairy cows decreases significantly. Due to calving stress, their appetite remains low and they lose weight rapidly. As milk yield rises quickly while feed intake remains low, the animals cannot meet their energy requirements and begin to lose body condition. Rapid weight loss leads to metabolic problems such as uterine diseases. The feed used for high-yielding dairy cows must not only have the right energy and protein balance but also be highly digestible and palatable. If cows are not fed with a balanced ration containing adequate levels of energy, protein, vitamins, and minerals after calving, they do not show estrus. Ovarian cysts and uterine diseases increase, and conception rates decline. Cows must have access to quality, clean, and fresh water at all times. Restricting water to fixed times reduces feed intake and causes rumen acidosis, which in turn leads to lameness.
