[Nutrition of dairy cows in late pregnancy during the housing period and its relationship to health and milk yields].

The relationship between the plane of nutrition in dry cows and heifers during late pregnancy on the one hand and health and milk production on the other is discussed. It is concluded from findings reported in the literature as well as from personal observations that when the animals are in normal condition, a plane of nutrition in excess of that required for maintenance plus from 5 to 10 kg. of milk will not enhance the milk yield but will increase the risk of milk fever, acetonaemia, digestive disorders, laminitis, udder problems and reproductive failure.
