【 摘 要 】

Black Bengal goats are mainly reared by economically weak farmers under extensive /semi-intensive systems. Thisbreed is very famous for excellent quality meat and high valued skin. At present, phenomenon of gradual shrinkageof grazing land is forcing farmers to adopt goat rearing by intensive management system (IMS). Therefore,assessment of production performance of goats under IMS would help to devise better management for higherprofits. Goats managed under IMS revealed that from birth, body weight of animals increased linearly up to 2 ½years of age, thereafter, body weight did not show any significant changes. Body weight was stabilized between 2-3years of age. From birth to 3 months age body weight enhanced by 164%, subsequently by 152% from 3 to 6 monthsage, then by 14 and 28% in next 3 months intervals, which warranted targeting better management during 6-12months of age to achieve more body mass production. Seasons non-significantly (P>0.05) influenced growth rate(g/day), highest in summer (30.78±5.30) and lowest in rainy (24.15±2.10). Male kids had higher (P<0.01) growthrate (29.72±2.62) than females kids (24.73±2.95). Reproduction showed higher proportions of female birth (60.17%)as compared to male (39.83%). Goats had reproductive efficiency of 50.98% singles, 43.14% twins and 5.88%triplets under IMS. The in-house production environment of IMS was stressful being THI 86-90 in summer andrainy seasons, and 77-80 in winter seasons. The flooring hygiene (1-4 scale) of goat houses in IMS ranged from3.18±0.08 to 3.72±0.06 in wooden to concrete floors. It was recommended that targeting for higher growth ratesduring 6-12 months of age and increase in proportions of multiple births might enhance productivity andprofitability of Black Bengal goat farming under IMS.
