Biological functions and adaptive nutrition for dairy cows

Different nutritional factors affect reproduction, growth, lactation, immunity and adaptation to thermal stresses. Such relationships should provide useful tools to adapt nutritional regimens to meet a specific production target and/or solve a specific production problem. Experiments have shown that the heifers that are adequately fed show an earlier oestrus cycle than those with poor nutrition. Other experiments have shown that the level of nutrition also affects the age of sexual maturity o
