  • Abstract:

The perennial scarcity of feed ingredients and high cost of finished feeds for livestock have led to a continuous search for alternative feed resources. Therefore, twenty eight 7- 8 weeks old fryer rabbits were used to investigate the replacement value of groundnut cake by raw, hot water and alkali treated cocoa bean meal (CBM) on growth performance, nutrient digestibility, biochemical and haematological parameters as well as gross cost-profit margin analysis. Seven isonitrogenous diets containing 17% crude protein were formulated. Diet 1 was the control, while 2-7 contained 25 and 50% each of the raw, hot water and alkali treated CBM as replacement for groundnut cake. The results showed that daily weight gain was significantly (P<0.05) inferior (8.7g) in the 50% raw CBM diet compare to other treatments. Feed intake and protein efficiency were significantly (P<0.05) superior in the control and 25% alkali treated rations compared to other diets. The crude fiber, ether extract and ash were significantly (P<0.05) least digested (66.1, 62.5, 64.7% respectively) in the raw and at 50% replacement level than 0% or 25% level of other processing methods. Total protein, albumin, glucose and red blood cells did not differ (P>0.05) significantly across the treatment means, but haematocrit, RBC and WBC were significantly (P<0.05) depressed in the raw CBM diets. The cost of production was cheaper in all treatment diets compared to the control. It is inferred from the study that fryer rabbits could be successfully reared with 25% replacement of ground nut cake by hot water or alkali treated cocoa bean meal without detrimental effect to the production parameters and health status, should feed ingredients scarcity persist in the future.
