Abstract: The study was aimed to understand the production performances of Jamuna basin lambs at different ages from some selected areas of Sherpur district. For this purpose, growth performance data on 360 lambs were collected from October 2018 to September 2019. Statistical analyses were done using SPSS-v-20 version computer software. The means of body weight of Jamuna basin lambs were 1.46±0.01, 3.58±0.05, 6.65±0.10, 9.84±0.25, 14.74±0.74 and 17.00±0.63 kg, respectively at birth, one, three, six, nine and twelve months of age. Sex had significant effect (p<0.05) at six month of age. Body weight and average daily gains were higher in male than female lambs at different ages. Litter size had highly significant effect (p<0.001) on birth weight and weight at one month of age. Single born lamb had higher birth weight and average daily gain than twins and triplets. A significant (p<0.05) effect was found on the weight at three months of age due to seasonal influence. Average Daily Gain (ADG) from one, three, six, nine and twelve month was found 119.33±2.25 & 119.00±2.20, 73.89±2.17 & 71.67±2.45, 54.67±4.03 & 54.83±4.67, 54.59±2.30 & 52.59±3.60 and 51.34±3.59 & 46.27±4.11 g/day, respectively in location wise. Mortality was relatively higher within 3 month of age. The improvement in litter size, body weight and survival represent potentially significant economic advantage of Jamuna basin lamb. In conclusion, sex, litter size, body weight, season, location and flock size used in the study are important source of variation for growth traits in Jamuna basin lamb.
