Evaluation the quality of Raw Cow’s Milk, in the Dairy Farm of College of Animal production Science and Technology

Abstract

The current research was conducted to study the quality of cow’s raw milk produced in the dairy farm of the College of Animal Production Science and Technology. A total of 30 samples of raw milk were collected from bulk milk of dairy farm from morning and evening milking and were then subjected to laboratory tests, including physicochemical (specific density, fat, lactose sugar,proteins, solids nonfat ash) and microbiological (Total bacterial count, total count of, total count of E.coli, total count of coliform, total count of Staphylococcus aureus) analyses. The results showed that no significant variations in the physicochemical and microbiological quality of the milk. The chemical composition of the raw milk samples was within the normal range. The microbiological contents showed presence of harmful bacteria mainly E.coli, coliforms, and Staphylococcus aureus therefore no significant differences were observed in the bacterial counts between the morning and evening milk. Its concluded that the raw cow’s milk of the College dairy farm microbiologically contaminated with many pathogenic bacteria which indicated bad hygienic conditions during milking.
