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 $1.55{\pm}0.06$ to $1.78{\pm}0.09kg$ with and over all mean of $1.66{\pm}0.031kg$. 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 $1.70{\pm}0.032$ and $1.61{\pm}0.03kg$ respectively. The birth weight was found to be the highest in 8 year age group that was $1.82{\pm}0.016kg$ and the lowest in one year group $(1.55{\pm}0.02kg)$.
