Abstract: Feeding trial was conducted using 150 birds of day-old Anak broiler chicks, to assess the effect of substituting raw sword bean meal for soybean meal in broiler finisher diets. 30 and 10 birds respectively constitutes a treatment and a replicate in a completely randomized design. Five experimental diets were used. Diet one was soybean based (control), while the test feedstuff quantitatively replaced 22.42, 44.84, 67.76 and 89.69% of soybean in diets 2, 3, 4 and 5, respectively. Feed intake of birds significantly (p>0.05) decreased as the quantity of raw sword bean increased in the diets. Weight gain followed the same pattern while feed-to-gain ratio significantly (p<0.05) increased as the quantity of raw sword meal increased in the diet. Mortality for birds fed diets 4 and 5 were 6.7 and 10%, respectively. The gross margin value favoured the control diet (N170.69) as opposed to the test diets with N169.69; N116.64; -N16.69 and -N61.88 for diets 2, 3, 4 and 5, respectively. Mean weight of organ showed significant (p<0.05) different for all the parameters measured with the exception of kidney and spleen. For the weight of cut-part, there were no significant (p>0.05) differences among treatment groups except for breast-cut and back-cut where diets 1 and 2 (24.03, 24.02) performed better than the others. The blood constituents showed significant difference (p<0.05) for all the parameters measured only with the exception of white blood cell. The PCV values fall within the normal range for all the treatment means. The RBC, MCH, MCHC, MCV values were abnormal starting from treatment 3 with the exception of MCHC starting from treatment 2. Serum albumin, creatinine, urea and alkaline phosphatase were higher in the test diets than in the control diet with the exception of treatment 2 where the value for alkaline phosphatase and albumin were lower than the control diet. The control diet had higher globulin value than the test diets. Liver, kidney and spleen were affected histopathologically. Raw sword bean meal cannot replace soybean meal quantitatively even at 5% dietary level of inclusion.
