Descripción

The study was conducted to evaluate the effect of including whole cassava root scrapings (WCS) in diets of broilers on performance and the metabolizability of dry matter, crude protein, and gross energy and on nitrogenous bala nce. Four hundred female and 100 male broilers from Ross strain were used in the performance and metabolism studies, respecti vely. In both studies, broilers were allotted in completely randomized bloc k design with five treatments and four replicates. The experimental unit was represented for twenty bi rds per box for performance study and five birds per metabolic cage for metabolism study. The treatmen ts consisted of diets containing 0, 5, 10, 15, and 20% WCS inclusion. Up to 5.1% WCS can be included in the diet of broilers from 1 to 21 without compromising feed conversion and productive efficiency index. Dry matter, crude protein, and gross energy metabolizability and the nitrogen balance of the diets are not influenced by the inclusion of whole cassava root scrapings up to 20% in diets of broilers from 1 to 21 days of age.
