Abstract

The objective of the research work to study the physico-chemical properties of Sangamneri goat milk namely fat, protein, lactose, total ash, titratable acidity, pH and total solids. During the entire study the fresh goat milk samples of Sangamnari goats were analyzed for chemical properties such as fat, protein, lactose, total ash, titratable acidity, pH and total solids also the minor content viz. Fe, Cu, Mn, and Zn of  Sangamneri goat milk in summer, rainy and winter seasons, respectively. The data were statistically analyzed by using completely Randomized Design (CRD) with three treatment and six replications. There was significant variation (P<0.05) was observed among the season of milking as regard iron, manganese, copper and zinc content of Sangamneri goat milk.


There was no significant (<0.005) among the seasons of milking in respect of protein, total ash, titratable acidity, pH and total solids. Whereas, significant variation P(<0.005) was observed among the season of milking as regard fat, lactose, iron, manganese, copper and zinc content  of sangamneri goat  milk. The  overall mean values of chemical composition of milk were 5.24 per cent fat, 3.62 per cent protein, 4.06 per cent lactose, 0.76 per cent total ash, 0.128 per cent titratable acidity, 6.42 pH and 13.62 per cent total solids of Sangamneri goat milk. The mean values of fat, lactose content of Sangamneri goat milk significantly increased from summer to winter season.
