Abstract

The study was conducted using the data collected from Buffalo Breeding and Development Farm, Bagerhat . Data covered the period from 1986 to 2000. Three hundred and thirty seven buffalo calves and sixty one buffalo cows of three genetic groups were considered for analysis of two traits, birth weight and gestation period, respectively . The genetic groups considered in the study were pure Nili, indigenous, 50% Nili 50% indigenous and 75% Nili 25% indigenous. Data were analyzed by Statistical Package for Social Sciences (SPSS) computer program. From the study, it was found that 75% Nili calves had greater birth weight (34.10 ± 2.74 kg) compared to pure Nili (33.20 ± 0.32 kg) and 50% Nili crosses (30.67 ± 3.86 kg). The gestation length of indigenous group was lower (303.04 + 2.17 days) compared to Nili buffalo cows (309.43 ± 4.36 days). The effect of genetic groups on birth weight was significant (P<0.001) and that was insignificant (P>0.05) for gestation period.
