Corms such as wild cocoyam [Colocasia esculenta] have potential to replace maize as a cheaper energy source in poultry rations. A feeding trial was conducted to evaluate the effects of graded levels of fermented wild cocoyam [Colocasia esculenta (L.) Schott] corm (FWCC), as substitutes for maize in the diets of broilers at the starter phase. One hundred and twenty unsexed day-old Hybro broiler chicks were randomly distributed to four dietary treatments in a Completely Randomized Design (CRD). There were 3 replicates per dietary treatment with 10 birds per replicate. Diet 1 without FWCC served as the control. Diets 2, 3 and 4 contained 10, 20 and 30% FWCC. Each of the diets represented a treatment. The experimental diets and clean drinking water were supplied ad libitum for 4 weeks (28 days) representing the starter phase of the broiler production. Result of the performance revealed significant (p<0.05) differences in feed intake, weight gain and feed conversion ratio. The economic analysis also showed that cost (Naira58.52) of a kilogram feed was highest (p<0.05) for the control and least (Naira53.10) for 30% FWCC. The least cost (Naira101.24) of feed per kilogram weight gain (p<0.05) was obtained for birds fed 30% FWCC compared to (Naira105.53) for the control. It was concluded that maize can economically be substituted with 30% FWCC in broiler starter diets.
诸如野生芋艿([芋属植物(Colocasia esculenta)])的球茎有潜力替代玉米,成为家禽日粮中更廉价的能量来源。进行了一项饲养试验,以评估分级水平的发酵野生芋艿([芋属植物(Colocasia esculenta (L.) Schott)])球茎(FWCC)作为肉仔鸡育雏期日粮中玉米替代品的效果。120只未区分性别的1日龄海波罗肉仔鸡雏鸡被完全随机设计(CRD)随机分配到四种日粮处理组。每个日粮处理组有3个重复,每个重复10只鸡。不含FWCC的日粮1作为对照。日粮2、3和4分别含有10%、20%和30%的FWCC。每种日粮代表一种处理。实验日粮和清洁饮水自由采食4周(28天),这代表肉仔鸡生产的育雏期。性能结果显示,采食量、体重增加和饲料转化率存在显著(p<0.05)差异。经济分析还表明,每千克饲料成本(58.52奈拉)对照最高(p<0.05),30%FWCC最低(53.10奈拉)。与对照组(105.53奈拉)相比,饲喂30%FWCC的鸡每千克体重增加的饲料成本最低(101.24奈拉)(p<0.05)。得出的结论是,在肉仔鸡育雏期日粮中,玉米可以经济地被30%的FWCC替代。
