1400 records of Mandya sheep Maintained at Livestock Research and Information Centre (Sheep), KVAFSU, Nagamangala, Mandya (Dst), Karnataka for seven years (2010-2016) were analyzed to estimate the effect of non-genetic factors viz., season of birth, year of birth, sex of lamb and parity of dam on birth and weaning weights. The overall mean of birth weight and weaning weight were 2.07 ? 0.01 kg and 10.13 ? 0.05 kg, respectively. The year of birth of lamb had significant effect on weaning weight and non-significant effect on birth weight. The season of birth of lamb, sex of the lamb and parity of dam were also significantly effects the birth weight and weaning weight of lambs.
