Factors affecting milk yield per day of age at second calving in Friesian X Sahiwal crossbreds



Factors affecting milk yield per day of age at second calving in Friesian X Sahiwal crossbreds



Indian Journal of Dairy Science 41(2): 230-231



Records of age at 1st calving, 1st lactation yield and 1st calving interval of 878 Friesian (F) X Sahiwal cows with levels of inheritance of 1/2, 5/8 and 3/4 F resp. were analysed. Adjusted mean milk yield/day of age at 2nd calving was 1.98, 1.90 and 1.97 kg for 1/2, 5/8 and 3/4 F cows resp., and was significantly influenced by farm, period (1974-78 and 1979-83) and month of calving, but not by level of crossbreeding.
