Impact of stage of lactation on chemical composition of red Sindhi cow milk

Abstract

The current study was carried on “Impact of stage of lactation on composition of Red Sindhi cow milk” on 20 healthy cows (Red Sindhi cow) selected from dairy farm of Agriculture college Dhule, Dhule. Cows were housed in barn under similar management conditions. Clean milk sanitary precautions were undertaken to produce clean milk by dry full hand method of milking. In different stage of lactation viz. 1st (Between 07 and 30 days), 2nd (Between 31 and 60 days), 3rd (Between 61 and 150 days) and 4th (Between 151 and 270 days) representative samples of 200 ml milk were collected. Fresh milk samples which collected in different lactation stages were analysed for fat, lactose, protein, ash and total solid (T.S.). It was found that stage of lactation had significant impact on fat, protein, ash and total solid (T.S.) while non-significant impact on lactose content of cow milk.
