Abstract

An experiment was conducted to evaluate the optimum inclusion level of 30 minutes
steam-treated Castor bean cake on the performance of broilers the steam-treated Castor
bean cake was used to replace GNC at graded levels of 25, 50, 75 and 100% Birds on
100% and 75% replacement died on the 1st and 2nd weeks, respectively. Birds on 50%
replacement survived while those on 25% replacement compared favourably with the
control. Result of the biochemical profile shows that there are no significant differences
in total protein, triglyceride and cholesterol across treatments. Results of haematological
parameters show that platelet count was significantly (P< 0.05) higher in the control
group and those on 25% inclusion which is higher than 50% inclusion level. Basophils
were significantly (P> 0.05) higher in the 25% inclusion group than 50% inclusion and
control while eosinophils, white blood cell count were significantly higher (P> 0.05) in
the 50% inclusion group compared to the others. There were no significant differences
in the packed cell volume, neutrophils, lymphocytes and monocytes across the
treatments. 25% inclusion level gave a better performance than 50% and has no adverse
effect on the health status of the birds. It was concluded that 30 minutes steam-boiled
CBC can replace GNC up to 50% level in broiler diets, without adverse effect on their
performance.
