This experiment was conducted to study the effect of citrus waste (CW) and cocktail enzyme supplementation on performance of broilers. Three-hundred-day-old broiler birds were divided into eight groups having four replicates of eight birds. Birds of control (T1) were fed a standard ration to meet their requirements; diets of the treatment groups T2, T3 and T4 were supplemented with citrus waste at 2.5%, 5% and 7.5%, respectively. Diet of group T5 was same as T1 but also contained cocktail of enzymes. Diet of groups T6 to T8 were similar to those of groups T2- T4, but were additionally supplemented with cocktail of enzyme at 100g/100kg of the feed. During starter phase, the group fed 5% citrus waste without addition of enzyme showed best response (P<0.05) with respect to various growth parameters. During grower and finisher phase final body weight, body weight gain and feed conversion ratio (FCR) was best (P<0.05) in the group where no CW was added followed by 5% CW supplemented group. Feed intake reduced with increased level of CW in the diet. For overall period of 42 days, the growth performance of broilers was best in groups fed no CW, the 5% CW supplemented group was best amongst different citrus waste supplemented groups. It was concluded that 5% citrus waste can be supplemented in broiler starter ration.
