In this study, feeding strategies which is one of the most important factors affecting milk yield and composition have been compiled and suggestions have been developed for dairy fram managers. Colostrum produced after the birth of dairy cattle is a sufficient nutritional source alone for strengthening the immune system of calves. After the first three days after the milk dry matter returns to normal milk levels and additional feeds are needed for healthy calve perfromences. Milk is an indispensable element of nutrition for people besides the feeding of calves. Therefore, herds are formed with high milk yield breeds and feeding manipulations, which are the most important factors affecting both milk yield and milk composition, need to be systematically regulated. Milk yield and composition ration roughage amount and quality, roughage / concentrate ratio, total mixture ration particle size, the amount and type of fat, protein source, carbohydrate source, such as many factors affect alone or interactively. The most affected milk components are milk fat and protein. The lactose and mineral content of milk are the most difficult milk components to be changed by feeding. There is a positive correlation between the milk components and the dry matter of the milk. The fat content of the milk increased with the addition of roughage and preserved fat used in the ration. The protein content of the milk, on the other hand, was increased by the addition of the protein source to the ration as resistant to rumen destruction or rumen degradable, considering the physiological status of the animal.
