Abstract

Present study was performed to assess the effect of the source and season on some physicochemical and microbiological properties of cow’s raw milk. A total of 120 samples of cow’s milk were collected from different sources (40 samples from each dairy farms, collection centres and groceries) during the summer and autumn season. Samples were subjected to physicochemical analysis by Lactoskan. The fat, protein, lactose, total solids, pH, added water and total bacteria count (TBC) were estimated. A total of 48 swab samples were collected from different farms (24 samples from each milkers hands, and milk utensils) during the summer and autumn season and were subjected to total bacterial count. General linear model was used to estimate the effect of source and season. The protein, lactose and added water were significantly affected by the source of milk collection while the milk fat, protein, lactose, total solids and TBC were significantly affected by season. In addition, a significant interaction between source and season was obtained on milk fat, protein, lactose and total solids.
