Effects Of Different Levels Of Dietary Methionine On The Carcass Characteristics Of Finisher Cockerels

Abstract

The experiment was conducted to determine the effect of different levels of dietary methionine on carcass characteristics of finisher cockerels. 500 day old cockerels were reared together initially for 7 weeks and at 8 weeks of age, they were assigned to 8 dietary groups or different methionine levels. Weights of the birds were taken at the beginning and end of the experiment. In the 16th week, the birds were slaughtered to determine various carcass measurements. Results indicated that daily weight gain was significantly (P < 0.05) affected by dietary treatments. The daily weight gain increased with increasing level or dietary methionine until it was optimised at 0.37% level. The dressing percentage and most other cut up parts (Drumstick, Thigh, Neck, Back, Breast, Wing) were significantly (P < 0.05) different. Although significant differences were observed for most organs (expect spleen), gut and comb measured, these were not however consistent with dietary treatments.
