Reproductive and Productive performances of Black Bengal Goats reared by the NGO Beneficiaries under semi intensive system in Bangladesh

Abstract

The present study was carried out to investigate the reproductive and productive performances of Black Bengal goats reared by moderate and ultra-poor households at three different districts of Bangladesh during March, 2008 to June 2009. Two-stage stratified sampling procedures were applied for selection of farmers to conduct field base experiment. A total of 12 households from moderate poor and 12 from ultra- poor were selected purposively from selected NGO beneficiaries. Three separate ultra poor households were also selected for rearing of bucks for breeding of the does of the study areas. As a whole, 81 goats rearing households from 3 districts came under the study. The average (mean±SE) age at puberty, services per conception, gestation period, age at first kidding, post partum heat period and kidding interval were found to be 234.16±6.54 days, 1.22±0.25 numbers, 145.61±2.17 days, 361.83±11.29 days, 67.00±4.97days and 252.45±3.57days, respectively. The effect of herd size on age at first kidding was significant at P<0.05, whereas on age at puberty and kidding interval it was found significant at P<0.01. The average weight at puberty, weight of kids, weaning weight, litter size, milk yield/day, milk yield/lactation and lactation period were found to be 10.01±0.19kg, 0.93±0.03kg, 4.82±0.53kg, 1.68±0.001 numbers, 75.20±15.22 ml, 5.18±1.11 liters and 69.83±10.09 days, respectively. Body weight of goats at puberty and weaning weight of kids found to be significant among groups at p<0.05 whereas milk yield/day found to be significant at p<0.01. Thus, it could be recommend that the body weight at puberty, weaning weight, milk yield/day, age at first kidding, age at puberty and kidding interval of Black Bengal Goat have significant impact on rearing.
