Influence of Lactation Order and Lactation Stage on Physico- Chemical Properties of Pantja Goat Milk

Goat is a versatile animal having short generation interval with lower investment cost and higher prolificacy. The present study was carried out at Goat farm, LPM, GBPUAT, Pantnagar. During the entire study the fresh milk samples of Pantja goats were taken according to lactation order and stage viz., 1st (Upto 30 days), 2nd (31 to 60 days) and 3rd (above 61 days) stage of lactation were analyzed for physico-chemical properties. The values of milk composition were significantly affected by lactation order and stage of lactation and their interaction. The color of Pantja goat milk was perfectly white in all the lactation order and lactation stages. The specific gravity and boiling point of milk increased significantly from 1st to 3rd lactation order and with advancement of lactation stage. The milk composition; fat, protein, total solids, solids not fat, total ash and chemical properties viz. titratable acidity of milk was increased significantly in advanced lactation order and stage of lactation except, pH, water and carbohydrate which showed a declining trend.
