The present study was carried out on 300 nos of One day old chicks of Srinidhi birds maintained semi intensive in lamphou pasna village of Chandel district of Manipur. The body weight was recorded upto20th weeks of age and body weight gain were recorded in weekly interval. The mean value of body weight at 0,4^th,8^th,12^th ,16^th and 20^th week of age were   37.10\(\pm\) 0.86g,412.50±3.06g,1045.25±6.82g ,1508.65±8.65g and 2031.75±11.20g 2875.35±12.08 respectively as the growth rate in scavenging system of rearing, were recorded as 38.12\(\pm\)0.59g 65.35\(\pm\)0.79 , 378.30 ± 2.78g, 910.87 ± 6.45g, 1277.73 ± 8.20gand1894.12 ± 16.40g and 2578\(\pm\)16.25 respectively, in Srinidhi birds under free range condition .The average age at first egg lay was observed to be 170.85 \(\pm\)2.40 and 178.65 \(\pm\) 2.43 cumulative  egg production upto 40  week of age  was recordedas108.75\(\pm\)1.70 eggs per bird  per year but only 92.67±1.68 eggs per year per bird under scavenging system. likewise. The average egg weight during this period was found to be 55.19±1.35g and survivability rate of the birds under the farm management system was recorded as 97.85% under semi intensive management system of rearing whereas in scavenging syatem record was found as 50.08 ±1.23g and 〖96.76〗^ survibality.
