Replacement value of cassava peels for maize in the diets of broiler finisher chickens

Abstract

A study was conducted to investigate the effects of replacing maize (MZ) with cassava peels (CSP) on the performance characteristics of broiler finisher. Five diets were formulated where MZ was replaced with CSP. The diets were diet 1 (100% MZ : 0% CSP), diet 2 (75% MZ : 25% CSP), diet 3 (50% MZ : 50% CSP) diet 4 (25% MZ : 75% CSP) and diet 5 (0% MZ : 100% CSP). Diet 1 served as control treatment. A total of 150 birds were used for the experiment. Thirty birds were assigned to each treatment and each treatment replicated three times with ten birds per replicate. The  birds ( arbor acre strain) were fed ad libitum for 28 days. Data on feed consumption, daily weight gain, feed conversion ratio, nutrient retention, water intake and cost benefit ratio were recorded. Results showed that average feed intake (AFI) and body weight gain (BWG) were significantly higher (P<0.05) for birds fed diet 3. Feed conversion rat io (FCR), nutrient retention and cost of feed consumed/bird decreased as CSP level  increased. Water intake showed no significant difference (P>0.05) among birds for all treatments. The cost per kilogram live weight gain was lower (P<0.5) for birds fed diet 3. Cost-benefit ratio showed a reduction of  20.6% in the cost of production of birds fed diet 3 over that of control group. Average mortality of 6.67 % was recorded for birds fed diets 1, 3 and 5. It was concluded that CSP can replace MZ without any adverse effects on the performance characteristics of finisher broilers.
