Abstract
The data 1241 birth, weights of Teddy goats maintained at Livestock Production Research Institute, Bahadurnagar, Okara, Pakistan, during 1975-1990 were used for this study. The mean birth weight during study period ranged from 1.55 0.06 to 1.78 0.09 kg with and over all mean of 1.66 0.031 kg. It was found that year of birth, type of birth, sex of kid and age of dam had significant (p < 0.01) effects on birth weight while the effect of season was found to be non-significant. It was inferred that single born kids were significantly heavier than twins and twins were heavier than triplets. The mean values of birth weight for male and female kids were 1.70 0.032 and 1.61 0.03 kg respectively. The birth weight was found to be the highest in 8 year age group that was 1.82 0.016 kg and the lowest in one year group (1.55 0.02 kg).
