Rearing black soldier fly is an efficient way to dispose of organic waste by converting them into protein-rich feed to substitute animal- and plant-based sources in animal feeds. The objective of this study was to determine the optimal inclusion level of black soldier fly larvae meal (BSFLM) as a substitute for soybean meal (SBM) in broiler diets and evaluate the impact on growth and carcass characteristics. Five isonitrogenous diets (D) (20% crude protein, CP) and isocaloric (3,200 Kcal/kg) were formulated such that BSFLM substituted SBM at 0% (control, D1), 25% (D2), 50% (D3), 75% (D4), and 100% (D5) on a protein basis. A total of 270 broilers (Cobb 500) were randomly assigned to the five treatments in triplicate per diet. BSFLM displayed higher fat content (44.84 ± 0.08%). Average daily feed intake (ADFI) decreased with an increase in BSFLM in the diets (p = 0.004). However, overall weight (OW) was high (1,296.97 ± 46.19 g) on 100% substitution of SBM with BSFLM (D5). Breast fat content averaged 6.06 ± 0.97 g for D1 and 15.30 ± 0.5 g for D5. This study has demonstrated that BSFLM can partially or wholly replace conventional SBM in the diet of broiler chicken.

饲喂黑水虻幼虫粉的肉鸡的生长性能和胴体特征:粪便污泥废物管理的产品

饲养黑水虻是处理有机废物的有效方法,可以将有机废物转化为富含蛋白质的饲料,以替代动物饲料中的动物和植物来源。本研究的目的是确定黑水虻幼虫粉 (BSFLM) 作为肉鸡日粮中豆粕 (SBM) 替代品的最佳添加水平,并评估其对生长和胴体特性的影响。配制五种等氮日粮 (D)(20% 粗蛋白,CP)和等热量日粮(3,200 Kcal/kg),其中 BSFLM 替代 SBM 为 0%(对照,D1)、25%(D2)、50%(D3)、以蛋白质计,75% (D4) 和 100% (D5)。总共 270 只肉鸡 (Cobb 500) 被随机分配到五个处理组,每个日粮一式三份。BSFLM 显示出较高的脂肪含量(44.84 ± 0.08%)。p = 0.004)。然而,用 BSFLM (D5) 100% 替代 SBM 时,总重量 (OW) 较高 (1,296.97 ± 46.19 g)。D1 的乳房脂肪含量平均为 6.06 ± 0.97 g,D5 的平均乳房脂肪含量为 15.30 ± 0.5 g。这项研究表明,BSFLM 可以部分或全部替代肉鸡日粮中的传统 SBM。
