Effects of replacement of soya bean meal by bambara nut sievate on the carcass and organ parameters of finisher broiler chicks

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) difference in the final live weight, carcass weight and dressed weight. Birds on 10% BNS and 5% BNS were not statistically different (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

Nutritional Evaluation of Different Processing Methods of Bambaranut (<i>Vigna subterranean</i> (L.) Verdc.) on Performance of Broiler Chickens

“…[21] have reported increase in nitrogen-free extract of bambaranut as a result of soaking in water. The values of NFE reported in this work are slightly lower than values (60.89) reported by [22] on roasted bambaranut; the variation can be attributed to cultivars of bambaranut. The different processing methods reduced the calcium content of differently processed bambaranut as reported by [17].…”

“…Slight decrease in ash content in cooked (2.50%) and roasted bambaranut (2.55%) were attributed to leaching and volatization while the slight increase in salt-treated bambaranut is attributed to increase in Na+ and Clions while the ash content of sprouted bambaranut remain fairly constant. Several authors have reported an increase in the ash content of bambaranut [21,22].…”

“…Livestock production in Nigeria is faced with a lot of problems, one of which is high feed cost. According to Ekenyem [1], feed cost represents about 70-80% of the total cost of production. The increase in the prices of conventional feedstuffs like soya meal, fishmeal and maize which are highly used in the production of animal feed, flour milling, oil industries as well as human consumption is as a result of the competition between humans and animals for grains and upward increase in human population.…”
