Abstract

The experiment was conducted to find out the effect of birth weight and milk yield on kid mortality in Black Bengal goats from birth to 90 days of age. The results indicated that birth weight of kids and milk yield of does had strong relationship with mortality during the pre-weaning period. Birth weight and milk yield had significant (P<0.05) effect on survivability for all the stages of growth up to 90 and 60 days of age, respectively. The kid survivability were highest and lowest having milk yield of does found to be 400-600 and 80-200 g day‾1, respectively. On the contrary it was also evident that survivability of kids increased from 39.8 to 90.0% with the increase of birth weight from 0.5-0.8 to 2.0-3.0 kg groups, respectively. The same trend of increased survival rate was observed when milk of does increased from 80-200 to 400-600 g day‾1 with corresponding in survival rate from 47.5 to 70.5%. It was concluded that birth weight of kids and milk yield of dam had a pronounced positive effect on kid mortality.
