ABSTRACT

The study was conducted at dairy and cattle improvement farm, Hathazari, Chittagong for a period of one year. A total of 82 dairy cows were selected during the period from June 03-July 04 and their information regarding milk production upto 180 days, productive and other reproductive parameters were recorded from farm record book. Average milk production (459.09 ± 138.09 liter), calving interval (634.59 ± 223.92 days), age at puberty (1205.02 ± 313.80 days), service per conception (1.88 ± 1.09), gestation length (273.08 ± 7.48 days) and birth weight of fetuses (18.78 ± 34 kg) were observed. The minimum and maximum value of these results was also observed. The highest milk production (487.54 ± 109.73 liter) was found in the cows with parity number 4-8 and the second highest (456.84 ± 169.58 liter) was found with the parity number 2 and the lowest milk production (445.79 ± 86.64 liter) was found with the parity number 3. The average production of milk was observed (473.44 ± 134.15 liter) in the cows required interval between 370-590 days and 444.74 ± 142.11 liter found in the cows required 591-1365 days. When the range of age at puberty was 1186-2270 days and 665-1185 days the average production of milk was 468.56 ± 161.92 liter and 450.50 ± 113.56 liter was observed, respectively. Comparatively more milk production was found (461.52 ± 151.89 liter) in cows required less number of services per conception was 1-2 than the cows required more number of services per conception was 3-6 and their milk production was 452.84 ± 96.60 liter. There was no any significance difference of production of milk among the different variables.
