Abstract: The objective of the present study was to investigate the effect of raw and differently processed (cooked, dehulled and toasted) kidney bean meal on the performance of broiler chicken. Histological examinations of internal organs were also conducted in a feeding trial that lasted for 56 days. Two hundred and twenty–five day old broiler chicks (Anak strain) were used for the study. There were five treatment groups of three replicates of 15 birds per treatment. Raw and processed kidney bean meal was used to replace 50% protein supplied by soybean in the control diet. Data collected was used to evaluate feed intake, weight gain and efficiency of feed utilization. The weights of liver, pancreas, kidney, heart and lungs were also recorded and tissue samples of each collected for histological examination. Food intake was unaffected by the dietary treatments. Significant (p<0.05) differences were obtained in Average Daily Gain (ADG) and efficiency of feed utilization (FCE). ADG in birds fed cooked kidney bean was significantly (p<0.05) higher than those fed toasted. ADG was depressed in birds fed raw and dehulled meals. Feed Conversion Efficiency (FCE) followed the same trend as ADG. The relative weight of the pancreas was significantly (p<0.05) increased, as a result of acinar hypertrophy. The kidney had severe congestion of glomeruli and distention of the capillary vessels with numerous thrombi in birds fed soaked and decorticated kidney bean meals. The weight of the liver was significantly (p<0.05) reduced in birds fed soaked and decorticated beans and it was characterized by marked coagulative necrosis and degeneration of the hepatocytes. The structural alterations were attributed to high concentration of residual anti-nutritional factors in the processed seeds. In conclusion, cooked kidney bean meal can be used to replace 50% protein supplied by soybean meal in broiler starter and finisher diets without any adverse effect on the performance and the intestinal organs.
