Effects of Crude Protein Levels and Binders on Feed Buoyancy

Orire AM and Emine GI

The research determined the effects of crude protein levels and selected natural binders (Cassava, Corn, Rice and Yam) on feed floatability. Eight (8) diets each were prepared at 30%, 35%, 40%, 45% crude protein level. Four parts each of the diets were incorporated with raw and gelatinized binders at appropriate inclusion levels. The results obtained were significantly different (p<0.05) for inclusion levels of crude protein and pellets floatability. Cassava binder gave the best floatability percentage of 100% for all crude protein levels which floated for 60 minutes while the raw binder incorporated pellets performed poorly except for yam binder that gave 70% floatation rate at 40% crude protein levels. Thus, while considering the right polysacharides as binder for on-farm floating feed, Cassava binder is recommended.
