This study was conducted to determine the level of mango seed kernel meal (20%, 30%, 40%) that can substitute corn in broiler ration and to determine the profit above feed medicine and stock cost using mango seed kernel meal in the ration of broilers. The 75 broiler (14 days old) chicks were distributed at random into five treatments employing Randomized Complete Block Design in three blocks from December 10, 2010 to January 17, 2011 at the Poultry Project of Don Mariano Marcos Memorial State University, North La Union Campus, Sapilang, Bacnotan, La Union. The results of the study revealed that 20% level mango seed kernel meal as substitute to corn in a formulated ration performed the best in terms of final weight, gain in weight, feed consumption, feed conversion ratio and profit above feed and stock cost.en-USThesis
