Evaluation of Rearing System on Body Condition Score and Mortality Rate of Black Bengal Goats

Abstract

The aim of the study was to compare the body condition score of Black Bengal goats reared under different rearing system and mortality rate between semi-intensive and intensive system under field condition. A total of 100 farmers were interrogated for fulfilling the parameters relevant to the purpose of current study. Age-wise classification of BBG were done into four groups, i.e., 1-3 month, 4-6 month, 7-12 month and 13-24 month of age to evaluate the body condition score among three rearing system. The present study found no substantial difference in the age group among 1-3 month, 4-6 month, 7-12 month of age managed under different system of rearing. However, a significant (p<0.05) difference was found in the age group of 13-24 month between semi-intensive and intensive system of rearing. It was observed that goats managed under intensive system was higher in body condition score by 6.81 % when compared to semi-intensive system of rearing. With subject to mortality rate, the average no. of goats died per year was comparatively higher in semi-intensive (1.20±0.10) than intensive (1.04±0.09) system of rearing under field condition. However, the mortality rate showed no significant (p<0.05) difference between the two system of rearing under field condition. From the current findings, it may be reported that the intensive system of rearing is better in terms of body condition score as well as minimizes the mortality rate of Black Bengal goat.
