Abstract
Eighty 4-weeks old broiler chicks (Anak 2000 strain) were used in a 28 days feeding trial to determine the effects of replacement of soya bean meal (SBM) by bambara nut sievate (BNS) on the carcass and organ characteristics of fin- isher broiler chicks. BNS replaced soya bean meal by weight for weight at levels 0%, 5%, 10% and 15% for treatments 1,2, 3 and 4; respectively which were replicated four times in a completely randomized design. Feed and potable water were supplied ad libitum to the birds. Also, ap- propriate medication, sanitation and other stan- dard management practices were strictly adopt- ed. At the 28th day, one bird was randomly picked from each replicate, starved of food for 24 hours and then slaughtered and eviscerated for carcass and organ evaluation. Weights were measured with digital weighing scale. Results of analysis of variance of carcass parameters showed significant (P 0.05) in the values above but only varied with birds on 10% and 15% BNS. Other carcass parameters were simi- lar (P > 0.05) in value between treatments. The liver, heart, gizzard and intestine significantly varied (P < 0.05) between their treatments. How- ever, kidney values did not differ significantly. From the results, it appeared that 5% BNS in- clusion is optimal for carcass and organ char- acteristics of finisher broilers.
Highlights
High cost of feed is a recurring limitation to monogastric animal production in Nigeria which has been rated at 70 - 80 percent of total cost of production [1]
Reference [2] has further blamed this nutritional adversity on geometric increase in the Nigeria human population without a commensurate increase in livestock production, over-dependence on imported livestock products, ignorance, inadequate technical skills, diseases and parasitism, environmental stress and high cost of ingredients
The fight to reduce the cost of poultry production becomes critically urgent in order to salvage Nigerians from the scourge of sub-optimal animal protein intake and malnutrition
Summary
High cost of feed is a recurring limitation to monogastric animal production in Nigeria which has been rated at 70 - 80 percent of total cost of production [1]. The cost of poultry production is so high that the products are so dear and unaffordable by consumers predisposing Nigerians to abject animal protein malnutrition. Soya bean meal is widely used as source of protein for poultry because of its ability to produce indispensable amino acids, high digestibility and low toxic substances. References [7] and [2] have defined bambara nut sievate as a by-product from the processing of bambara nut into its flour for human use They further stated that BNS has no direct food use by man and are carelessly disposed within and around the processing plants and constitute environmental pollutants. This study is done to determine the effect of replacing soya bean meal by bambara nut sievate on the carcass and organ characteristics of finisher broiler
