Abstract | The rubber seed meal (RSM) that obtained from rubber seed tree is a rich source of protein. However, it also contains high levels of hydrogen cyanide that cause hindrances in the utilization of RSM as animal feed. The present study was conducted to explore the potential of detoxified RSM in broilers by replacing it with conventional protein feed stuffs. A 42-d experiment was carried out to investigate the effect of differently processed (detoxified) RSM on the haematological and serum biochemical indices of broiler chicken. Five diets were formulated using differently detoxified RSM consisting of soaked, boiled, toasted and fermented RSM as well as the corn-soybean based control diet. Three hundred, 1- day old Arbor acre broilers were randomly distributed into five dietary treatments with six replicates of 10 birds each in a completely randomized design. After 42 days, three birds per replicate were randomly selected for haematological and serum biochemical evaluation. Results showed that boiling and fermentation were very efficient in lowering the level of cyanide in the seed followed by toasting and lowest in soaking method. Results of haematological evaluation showed a significantly higher (P<0.05) haemoglobin level, mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) in boiled and fermented RSM fed groups than other RSM fed groups. While serum biochemistry revealed that birds fed control, boiled and fermented RSM diets have higher (P<0.05) concentration in total protein and albumin but with reduced (P<0.05) concentration of creatinine, uric acid and cholesterol than those fed soaked and toasted RSM diets. In conclusion, results showed that incorporation of boiled and/or fermented RSM have better effects on the blood biochemical indices and haematology of the broilers.
