ASSESSMENT OF CARCASS CHARACTERISTICS AND ORGAN WEIGHTS OF FINISHED BROILER CHICKENS FED UREA PLUS METHIONINE TREATED AND FERMENTED SORGHUM BEER RESIDUE

Résumé

The carcass yield and Organ weights of finished broiler chickens fed urea plus methionine supplemented and re- fermented sorghum beer Residue (RSBR) were investigated after a 4-week finisher period. At the end of the finisher phase, three birds from each pen were selected for carcass analysis. The dressing
percentage of birds on 50% RSBR diet was significantly higher (P < 0.05) than those on control and other diets. The breast weight percentage for birds on the control was observed to be highest significantly (P<0.05) while that for birds on 100% RSBR diet to be the lowest significantly (P<0.05). The thigh percentage of birds on control and 50% RSBR diets were similar but significantly (P<0.05) higher than those of birds on other diets. Heart and gizzard percentages of birds on 100% RSBR diet were significantly higher (P < 0.05) than those on control and other diets. This study indicates that up to 75% RSBR can adequately support carcass yield and organ weights without detrimental effect on finisher broiler chickens.
