Performance of broiler chicken under floor system of management fed with different processed feed

摘要

An experiment was carried out to find out the performance of broiler chicken fed with different processed feed under floor system of management. Trials were conducted covering all the four major seasons. In each trial 60 day old vencob chicks belonging to the same hatch were used. They were subjected to control-feed with broiler mash (C) T_1-fed with UV rays irradiated mash in the intensity of 80W/cm~2 at 253.7 nm for five minutes and T_2-fed with UV rays irradiated mash processed in microwave power of 1200 W at 2450 MHZ for five minutes. The body weight gain was significantly (P<0.05) higher in T_1 and T_2 higher than control in irrespective of season. Feed efficiency was significantly (P<0.05) lower in control group than T_1 and T_2 during coldand hot season whereas during northeast monsoon and southwest monsoon only numerical variation was observed. The mortality was significantly (P<0.01) higher in control group during hot and northeast monsoon. The UV rays irradiated mash fed group given higher yield to 73.2 per cent of eviscerated yield. The cost of production per kg of meat in T_1 was Rs.30.96 and T_2 Rs.30.99 as against 34.24 in control group. The BEFI was similar in T_1 and T_2.
