EFFECT OF MAIZE REPLACEMENT WITH VARYING LEVELS OF ROASTED CASSAVA SIEVATE ON PERFORMANCE, CARCASS TRAITS AND ECONOMICS OF PRODUCTION OF BROILER CHICKEN

Abstract

Nigeria is the world's largest producer of cassava. There is a growing interest in exploring the use of cassava by-products, such as cassava sievate, as alternative feed ingredients. This experiment was conducted to examine the growth performance, carcass traits and economics of production of broiler chickens fed maize replaced with varying roasted cassava sievate. One-hundred-day-old chicks were used to experiment for six (6) weeks. The birds were fed 0% 10% 20% 30% and 40% levels of maize replaced with roasted cassava sievate meal. The experiment showed that roasted cassava sievate meal influenced the growth performance of broiler chicken. Also, the experimental diet influenced feed intake in broilers. Results showed that maize replaced with roasted cassava sievate diet has a significant effect on liveshrunk, defeathered and dressed carcass weights of the birds. The breast muscle percentage of the birds was influenced by the inclusion of cassava sievate in the broiler diet. The result also showed that percent broiler primal parts was not significantly different among the treatment groups. Diest did not exert any significant difference in the percentage of liver, pluck, gizzard and heart of experimental birds. Price per kg feed reduced with increased levels of replacement. However no significant difference in price per kg bird produced. There was no mortality throughout the experimental period, which suggested that roasted cassava sievate meal has no deleterious effect on the experimental birds.
