Abstract:

The study was carried out to investigate productive and reproductive performances of crossbreds and indigenous dairy cows. A total of 200 dairy cows belonging to 10 farms of Sylhet district were selected randomly of which 50 cows were Holstein Friesian cross, 50 cows were Sahiwal cross, 50 cows were Sindhi cross and 50 were indigenous breed. The highest average milk yields day -1 cow -1 and total lactation yield cow -1 was observed in Holstein Friesian cross (9.82±2.92; 2899.13±1280.52 liter) followed by Sahiwal cross (6.13±2.85, 1773.60±1107.68 liter), Sindhi cross (4.35±1.12; 1127.24±342.32 liter) and indigenous cows (2.41±0.72; 541.42±144.71 liter). The lactation period (days) of crossbreds dairy cows was significantly (p<0.01) higher than native indigenous cows. The postpartum heat period and calving to first service were highest in Sindhi cross and indigenous cows. The age at first calving (months) was almost similar in different crossbred cows but significantly (p<0.01) higher in indigenous cows. Considering all the parameters studied, Holstein Friesian cross showed better performance followed by Sahiwal cross, Sindhi cross and indigenous cows.
