A total 131 dairy cows of two genetic groups as IG (117 heads) and HF (14 heads) were selected randomly. The study found that the average milk yield per day of HF and IG cows were 7.64±1.74 and 1.75±0.07 liters/day, respectively. The milk yield was found significantly (p<0.01) higher in HF cows than of IG cows. The lactation period of HF was significantly (p<0.05) higher than of IG cows. Age at first calving of IG cows was significantly (p<0.01) 4 months higher than HF cows. The number of service per conception was almost similar for HF and IG cows. Higher significant difference was found in Post-partum oestrus (p<0.05), dry period (p<0.01), calving intervals (p<0.01) of IG than HF cows. The gestation length of HF and IG cows was significantly indifferent. Above biological studies mentioned better productive and reproductive performance of HF cows than IG cows.</p><p><em>Bang. J.
