ABSTRACT A feeding trial with Blighia sapida seed meal, BSSM detoxified traditionally by soaking and boiling and chemically treated with glycine and riboflavin was carried out. 120 day old cockerel chicks were fed the graded levels of 15, 17.5, 20 and 22.5% detoxified BSSM in diets and their blood composition was studied. Results showed that WBC, PCV, RBC AND Hb were high on diet containing low level of BSSM while the reverse was the case with increase in level of the tested feedstuff in diets. Similarly, bilirubin excretion was low on diet containing low levels of BSSM. It is concluded that including detoxified BSSM in the diets above 15% level may be harmful to the fed livestock. Further research using similar treatment will be conducted to step up dietary inclusion of BSSM.
