TWO-STAGE COOKING AS A METHOD OF IMPROVING THE NUTRITIVE VALUE OF JACKBEAN (Canavalia ensiformis) FOR BROILERS

Abstract

A 4 - week feeding trial was conducted to determine the effect of 2-stage cooking on the 1988; Wyss and Bickel, 1988). The best known nutritive value of jackbean (Canavalia ensiformis) for broilers. Two-stage cooking is one of the practices employed in the village for preparing toxic foodstuffs for human consumption. Jack Beans were cooked for 40 minutes at the end of which the cooking water was thrown out. Fresh water was added and it was valuable as a protein and energy supplement cooking continued thereafter for another 40 minutes. The two-stage cooked jackbeans were dried, ground and included in a broiler finisher diet at 0,10,15 and 20% levels, respectively, and each diet fed to 30 broiler chickens for 4 weeks. There were no significant (P <0.05) differences in feed intake, growth rate and feed conversion ration among the four experimental groups.
