Abstract A study was conducted to see the effect of dietary incorporation of alkali (1.5% NaOH, w/w) processed solvent extracted karanj cake (SKC) supplemented with methionine on serum haemato-biochemical profile, humoral immune response and skeletal status of broiler chickens during 0 to 8 weeks of age. Incorporation of alkali treated SKC with or without methionine supplementation did not significantly influence the serum concentration of a hemoglobin, glucose, protein, albumin, globulin and uric acid or the activities of enzymes such as AST, ALT or LDH. However, alkaline phosphatase (ALP) activity increased significantly (P<0.05) in the birds fed alkali treated SKC diet as compared to that of either reference diet or alkali treated SKC incorporated diet supplemented with methionine. The feeding of alkali processed karanj cake replacing 12.5 per cent protein of soybean meal had no significant influence on antibody production as measured on 5th day of sheep RBC inoculation. However, the persistency of antibody production decreased significantly. On the contrary, supplementation of 0.2 per cent methionine to the same diet alleviated the depression in antibody production. Incorporation of alkali treated SKC replacing soybean meal nitrogen at (12.5%) level, with or without methionine supplementation, had no influence on the serum concentrations of Ca and P, bone ash, leg score and bone breaking strength.
