Factors Affecting Yield and Composition of Milk
نویسنده
چکیده
The variation in composition and daily yield of milk is a regular phenomenon in all milking animals. Broadly, the factors which are responsible for such variations can be divided into (1) Physiological, which will be governed by the genetical make up and (2) Environmental, such as age, number of previous lactations, pregnancy, nutrition status, etc. The dairyman has hardly got any control over the physiological factors but he has some control over the environmental factors. A thorough understanding of the factors that change the environment of the dairy cattle can be used to take advantage of some of the changes in milk composition and yield that occur during a normal lactation.
