N. Sultana, M.M. Rashid and S.M.J. Hossain    

Abstract: The study has been conducted to compare the productive and reproductive performances of indigenous and crossbred cows. Fifty small diary farms were taken covering 8 Thanas of Jessore and a random sample of 75 cows. Statistical analysis showed significant differences (P<0.01) within the age at puberty, service per conception, calving interval, milk yield and lactation length of different types of dairy cows. In case of gestation length, there were no significant (P>0.05) differences. Shortest age of puberty (6.42 days) and highest service per conception (2.43) were found for Friesian cross. There was no difference in the gestation length (278 days) of the four crosses. The highest value (278 days) was observed in indigenous cow. Friesian cross were observed to have the lowest calving interval (414 days). The highest daily milk yield (7.2 liter) were observed in Friesian cross. Considering above parameters except service per conception, Friesian cross cows were more profitable, acceptable and highest producers than others.
