An investigation was undertaken to study the effects of feeding mango seed kernel (MSK) whose annual production in the country is about 14 million tons and about 15 lakh tons in Bihar, on growth performance, carcass quality and cost of feeding in broiler. A total of 200 chicks were randomly distributed into 5 groups of 40 chicks each. Each dietary treatment was replicated twice. Five diets in which MSK replaced 0, 2.5, 5, 7.5 and 10% levels of rice polish were fed ad libidum to starter broilers (0–4 weeks). The body weight gain, feed conversion efficiency, performance index and feed intake of birds were simillar in all the dietary treatments.The feed cost/kg weight gain (Rs.) of broilers was found minimum in the group fed with 10% of MSK. The MSK inclusion had no significant (P>0.05) influence on the dressed weight, eviscerated weight and ready to cook chicken weight and also no significant (P>0.05) effect on weight of liver, gizzard, heart and spleen was observed. Net profit per bird was 45.29, 45.34, 46.01, 47.05 and 47.43 percent, respectively of input for all five treatments, respectively.Thus, it can be concluded that MSK can be included in the ration of broilers upto 10% without affecting their performance.
