Abstract
In the current investigation efforts were made to study significance of feeding mushroom waste at graded levels on performance of broilers. The control group (T0) fed diet without mushroom waste and the dietary treatment groups i.e. T1, T2 and T3 fed diets with mushroom waste at graded levels of 2 %, 4% and 6%. Broilers fed diets with mushroom waste at 2 % level attained higher live weight and gain in body weight than the broilers fed diets with 4 or 6% mushroom waste and the birds fed control diet. The percent enhancement in gain in body weight in treatment groups T1, T2 and T3 relative to control was 12, 6.62 and 5.76 %, respectively. Feed intake was increased marginally in all treatment groups in comparison to control and the percent increase was by 4 to 9 % in mushroom fed birds over control. The dietary treatment groups improved FCR in groups T1, T2 and T3 by 2.85, 1.71 and 1.71, respectively. There was reduction in mortality due to addition of mushroom waste at elevated levels of 4 or 6 % in broilers. The broilers fed diets with mushroom waste demonstrated better nutrient retention and slightly increased antibody titres against Ranikhet disease. The dressing yield and other carcass quality parameters were comparable among different experimental groups. The feed cost was reduced on inclusion of mushroom waste at graded levels relative to control. The addition of mushroom waste to broiler diets was found to be cost-effective. In conclusion, the results of the present experiment suggested that feeding of mushroom waste to broilers at 26 % proved beneficial to improve growth, nutrient retention and net profit in broiler production. Furthermore, feeding mushroom waste at a level of 2% was comparatively more beneficial to improve production performance of broiler chickens.
