Data on body weights at birth, 3, 6, 9 and 12 months of age, of 3465 kids of Sirohi breed born from 1447 does and 59 bucks, spread over a period of seven years (2006–2012) were collected. Flocks were maintained under All India Co-ordinated Research Project on Goats in Nathdwara, Railmagra and Devegarh clusters of Rajasamand, Bhadsoda cluster of Chittorgarh and Vallabhnagar cluster of Udaipur districts of Rajasthan. The least squares means for body weights at birth, 3, 6, 9 and 12 months of age were estimated as 2.10±0.06, 13.29±0.43, 16.94±0.65, 20.00±0.87 and 24.87±1.11 kg respectively. The effects of sire, cluster, year of birth, type of birth and sex of kid were significant (P<0.05) on body weights from birth to yearling age. Season of birth had significant (P<0.05) effect on 3, 6, 9 and 12 months body weight. The weight of doe at kidding had positive and significant (P<0.01) effect on birth, 3 and 12 months body weights. Utilization of the information for formulating breeding plan will be helpful in bringing about further genetic improvement of this breed.
