Abstract

A total of 601 lactation records of 205 Holstein Friesian and Sahiwal crossbred cows, which comprised of HF purebred, HF 62.5% and HF 50–62.5% from 1st to 4th parity over a period of 9 years from 1998 to 2006 maintained at Military Farm, Jammu Cantonment (J&K, India) were used to study the effect of genetic and non-genetic factors on production traits The overall averages for lactation length (LL), total lactation milk yield (TLMY) and milk yield per day of lactation length (MYDL) were estimated as 299 days, 2957.80 kg and 9.88 kg respectively.
