Abstract:
In order to optimize production strategies, ensure high quality products, and satisfy consumer demands throughout the year, it is essential to understand how seasons affect milk production and composition. The aim of present study is to find out how spring and summer season affect the milk production, composition and physico-chemical properties of Jersey crossbreds. Our result shows that the mean values of fat, protein, TS, SNF, lactose, freezing point, density, pH and specific gravity in spring were 4.997, 3.237, 13.095, 8.095, 4.472, -0.524, 28.975, 6.610 and 1.031, respectively, and in summer were 4.862, 3.145, 12.872, 8.008, 4.379, -0.516, 28.902, 6.581 and 1.031, respectively. The analysis of variance shows season has highly significant (p<0.01) effect on test day milk yield.
