Abstract:
Composition of milk is greatly influenced by seasonal variation. Major variation is observed in fat composition. Pakistan is blessed with high genetic potential animals like Nilli Ravi and Sahiwal cow. Milk is highly nutritive food having macro and micronutrients which are necessary for the growth and development of humans. India is largest milk producing country in the world while Pakistan stands on 4th. The aim of this study was to evaluate the composition of milk of different breed of cow and buffalo and effect of seasonal variation on composition of milk. Samples from both morning and evening milking were collected in sterilized glass bottles from dairy farm of university of Agriculture, Faisalabad and evaluated for 6 months. During transportation, samples were kept in ice box at 4°C. Proximate analyses like crude protein, fat, lactose, moisture and ash content was done to check fluctuation in composition of milk. Additionally, some physicochemical analysis like total solids, solids not fat, specific gravity, pH and acidity was also done. At the end, all the data obtained was subjected to statisticalanalysis to check the level of significance by applying LSD with two-way ANOVA. It was concluded from the results of the current investigation that effect of seasonal variation and milking time on composition of milk was significant. Fat percentage in milk was highest in January and moisture content was highest in June as compared to other months. Total solids, protein and lactose contents were maximum in winter and minimum in summer season. Effect of season was highly significant on total solid, solid non-fat, acidity, lactose, fat, protein, pH and moisture while ash was significantly affected by season and Specific gravity was non-significantly affected by season. The total solid, solid non-fat, pH, moisture, lactose, fat and protein content of milk were highly significant by breed while ash was significantly affected by breed but acidity and specific gravity were non-significantly affected by breed.
