Abstract:
The main aim of this study was to evaluate and compare the physico-chemical properties and proximate composition of milk samples obtained from different species mainly buffalo, cow, sheep and goat of north coastal area of Andhra Pradesh. The composition of milk may vary from place to place in species which depends upon several factors. The objective was to explore the variability of the nutritional characteristics of the original milk. The samples were analyzed for physico-chemical properties such as pH, specific gravity and titratable acidity, proximate composition like fat, protein, carbohydrate, ash and total solids. It was observed from the results that among all the species buffalo and goat milk showed higher levels of all the constituents than that of cow and sheep milk. Buffaloe milk showed higher specific gravity, titratable acidity, ash, and protein content than cow milk, but had a lower lactose level than goat and cow milk. All the tested parameters were similar in buffalo and goat milk except lactose which was higher in goat milk.
