Abstract:
ICAR Research Complex for NEH Region, Tripura centre is maintaining a Black Bengal goat farm to cater the need of farmers and institute research. The data collected for 5 years regarding pre-weaning growth performance of kids and analysed. The birth rate of Black Bengal kids were recorded in institute goat farm, averaging 1.61 kids per doe and the prolificacy rate was 146.54%. The percentage of single birth was recorded as 27.87%, multiple births as 72.13.7% out of which 57.54% was twin, 13.43% was triplet and 1.16% was quadruplet. The overall birth and weaning weights of Black Bengal kids were 1.11 ± 0.06 kg and 4.82 ± 0.20 kg, respectively and pre-weaning average daily gain was 41.22 ± 3.15 gm. In the study it was found that the birth weight of male and female kids was 1.12±0.07 kg and 1.07±0.04kg, respectively. Even though male kids recorded 4.46% higher body weight than female kids but, no significant difference was observed. Birth weight, weaning weight and pre-weaning daily gain of single, twin, triplet and quadruplets born kids were 1.14 ± 0.10 kg, 5.69 ± 0.44 kg and 50.56 ± 4.51 gm, 1.11 ± 0.05 kg, 5.38 ± 0.24 kg and 47.44 ± 3.53 gm, 1.09 ± 0.12 kg, 5.19 ± 0.37 kg and 45.55 ± 4.02 gm, 1.05± 0.11 kg, 4.87 ± 0.37 kg and 42.44± 5.02 gm, respectively. The birth weight, weaning weight and average daily gain of single birth were higher than that of twin, triplet and quadruplets born kids without significant difference among the births.
