ABSTRACT
In the dairy industry milk is the most valuable product. The market value of milk depends on the amount of yield and content of fat in milk. Breed or genetic factors are mostly correlated with the production rate and fat content in milk. For example, Jersey breed cattle have the highest fat and protein percentage in milk than other breeds. However, the quality of milk also depends on other dietary factors such as crude fiber and crude protein content of the diet. Fermentation of crude fiber in the rumen produces large amounts of acetic acid and butyric acid which act as a derivative of milk fat. Milk protein concentration depends on the crude protein level in the diet. In this study milk and feed samples were collected from eight dairy farms at Chattogram Metropolitan Area to investigate the dietary effect on milk composition. The highest fat, SNF percentage, and protein percentage of the milk sample were found in the case of the Munna dairy farm in which the crude fiber level and crude protein level of the feed sample were higher than other dairy farms. The lowest fat, SNF percentage, and protein percentage of the milk sample were found in the case of the Moinuddin dairy farm in which the crude fiber level of the feed sample was lowest but the level of crude protein in the feed sample was near to Munna dairy farm. A better amount of crude protein in the feed sample was found in the case of the Moinuddin dairy farm. However, due to mastitis and a poor management system, the protein content of milk on this farm was poor.
