A Comparative study on the productive and reproductive performances of crossbreed cattle on commercial dairy farms in Karnaphuli Upazila, Chattogram, Bangladesh

Abstract

The study was conducted to evaluate and compare some productive and reproductive performances of different crossbreed cattle reared in the different dairy farms of Karnaphuli upazila, Chattogram. A total of 107 cows belonging to different breeds such as Holstein Friesian cross (HF cross), Jersey cross, Sahiwal cross, Sindhi cross, Brahman cross, Haryana, and Gir were selected, and their information regarding productive parameters like body weight, birth weight and daily milk yield and other reproductive parameters like parity, days open, service per conception were collected from the farms. Results showed that the mean daily milk yield of HF cross, Jersey cross, and Sahiwal cross were 12.57±0.13, 12.37±0.88, 07.67±0.33, respectively, and in second to third parity, it was the highest. According to the farm, the overall mean body weight was 398.84±7.20. Based on breed, the mean birth weight of HF cross, Jersey cross, Sahiwal cross and Brahman cross were 28.28±0.31, 29.00±1.00, 28.66±0.67 and 30.00±0.00, respectively. Based on breed, the mean days open of HF cross, Jersey cross, Sahiwal cross and Haryana were 75.00±2.04, 82.50±14.36, 60.00±0.00 and 90.00±0.00, respectively and based on parity, the first parity showed the highest (82.50±5.12). Based on breed, the mean service per conception of HF cross, Jersey cross, Sahiwal cross and Brahman cross were 2.53±0.53, 2.75±0.25, 2.33±0.33 and 2.50±0.50, respectively, and in the case of parity in first, second, third and fourth parity were 2.50±0.13, 2.57±0.07, 2.46±0.09 and 2.33±0.67 respectively. Therefore, it could be concluded that Holstein Friesian crossbred cows are more suitable for profitable dairy farming in Bangladesh.
