MANAGEMENT AND PERFORMANCE OF AVAILABLE CATTLE UNDER EXTENSIVE FARMING SYSTEM AT HATIL, MUKTAGACHA, MYMENSINGH, BANGLADESH

Abstract

The present study was conducted to find out the present status of available cattle in Bangladesh. Their rearing system, productive and reproductive performance. Data was collected from thirty local cows and heifers were taken under this study from 17 farmers. Age , number of calving, conception ratio, gestation period, post partum heat period, milk production, birth weight of calves, age at first calving. So considering the age at first parturition of cross(HF),cross(Shahi) and desi were 3.71±0.75 years, 3.66±1.15 years and 3.54±3.54 years respectively, average daily milk yield of cross(HF),cross(Shahi) and desi were 4 ± 1.41 L,2.66±1.15 L and 1.64±o.65 L respectively, number of calving of cross(HF),cross(Shahi) and desi were 2.714±1.112, 2.667±2.082, 2.88±1.727 repectively, conception ratio of cross(HF),cross(Shahi) and desi were 1.285±0.487, 2.5±0.707, 1.478±0.926 respectively, calf weight of cross(HF),cross(Shahi) and desi were 23.571±4.157, 25±5, 18.6±2.244 respectively , parameters indigenous cows rearing under rural condition was a profitable practice in selected areas minimizing effect of climate stress and thrives well in hot and humid temperature maintaining phenotypic and productive performance of Bangladesh.
