Abstract:
A study was conducted to assess the influence of parity on milk composition of Jersey X Red Sindhi crossbred cows maintained at Post Graduate Research Institute in Animal Sciences, Kattupakkam. Animals with consecutive parities were grouped together. Animals with parity 1 and 2 were classified as group I; 3 and 4 as group II; and 5 and 6 as group III. Milk samples were collected at weekly interval for the period of six month from December 2015 to May 2016. The milk composition viz., fat, solid not fat, total solid, protein and lactose content of milk were analyzed manually. All parameters of milk except lactose, showed highly significant (p< 0.01) difference between parity group.
