Abstract

A study was carried out on the reproductive and calf growth performance of Kedah-Kelantan (KK) and Australian Brahman (BR) in a commercial beef cattle farm (Darabif). Records from dam, calf, body weight, rainfall and livestock return were analysed. There was no significant difference in age at firet calving between breeds (P < 0.01). A breed difference was only found in the first 3 calving intervale (P < 0.01) but not in the 4th calving interval (P < 0.05). Birth weight, weaning weight and ADG showed a highly significant difference between breeds (P < 0.01) (BR > KK). Within breeds, sex difference was not significant in all the parameters (P < 0.05). Year effect between breeds was highly significant in all the calf growth parameters (P < 0.01). There was a highly significant difference between the sexes in birth weight and ADG (P < 0.01) from year to year while weaning weight and days to weaning indicated no significant difference (P < 0.05). The means of age at first calving and calving intervals of KK ve BR were 1,023 + 143 days (n = 50) vs 1,077 + 189 days (n = 38), 338 days - 365 days vs 368 days - 426 days. The least square means of birth weight, weaning weight and ADG of KK vs BR were 18.1 kg vs 31.3 kg, 103.7 kg vs 153.1 kg and 0.42 ve 0.59 kg. The figures for both these sets were comparable and in most cases better than those of previous studies. There was no apparent seasonal trend between % calving (r < 0.22) and mortality (r < 0.09). (preweaning and total mortality) with rainfall. Mean % calving for the past 6 years was KK - 77%, BR - 68% (KK > BR). Mortality % of KK and BR were low (< 5%).
