The objective of this experiment was to investigates effects of inclusion of black soldier fly larvae (BSFL) on growth performance, relative organ weight, and meat quality of broiler chickens. A total of 180 1-d-old broiler chickens were randomly allotted to 1 of 3 dietary treatments with 5 replicates. Each replicate consisted of 12 birds. Experimental diets were formulated to contain full-fat BSFL at inclusion levels of 0 %, 1 %, and 2 %. These diets were provided on an ad libitum basis for 5 wk. Results indicated that birds fed diet containing 1 % BSFL had greater (P < 0.05) feed efficiency than those fed diets containing 2 % BSFL. However, BW gain and feed intake of broiler chickens were not affected by increasing inclusion levels of BSFL in diets. Increasing inclusion levels of BSFL in diets showed a quadratic relationship (P < 0.05) with relative thymus weight. For meat color, values for redness (a*) and yellowness (b*) were decreased (linear, P < 0.05) as BSFL inclusion level of diets increased. Thiobarbituric acid reactive substance decreased (quadratic, P < 0.05) with increasing inclusion levels of BSFL in diets. Melanin concentrations in breast meat and liver characteristics were not affected by increasing inclusion levels of BSFL in diets. Increasing concentrations of BSFL in diets increased myristic acid concentrations (linear, P < 0.01) and eicosapentaenoic acid concentrations (linear, P < 0.05) in breast meat. These results suggest that dietary supplementation of BSFL has positive effects on immune organ weight, breast meat quality, and fatty acid compositions in breast meat. Therefore, BSFL can be used as a feed ingredient for broiler chickens. Also, we suggest that dietary supplementation of 1 % BSFL improves the performance and health of broiler chickens.
本实验的目的是研究添加黑水虻幼虫（BSFL）对肉鸡生长性能、相对器官重量和肉质的影响。总共180只1日龄肉鸡被随机分配到3种日粮处理中的1种，每种处理有5个重复。每个重复包含12只鸡。实验日粮的配方中全脂BSFL的添加水平分别为0%、1%和2%。这些日粮以自由采食的方式提供5周。结果表明，饲喂含1% BSFL日粮的鸡比饲喂含2% BSFL日粮的鸡具有更高（P < 0.05）的饲料效率。然而，日粮中BSFL添加水平的增加对肉鸡的体重增加和采食量没有影响。日粮中BSFL添加水平的增加与相对胸腺重量呈二次关系（P < 0.05）。对于肉色，随着日粮中BSFL添加水平的增加，红色度（a*）和黄色度（b*）值呈线性下降（P < 0.05）。随着日粮中BSFL添加水平的增加，硫代巴比妥酸反应物质呈二次下降（P < 0.05）。日粮中BSFL添加水平的增加对胸肉中的黑色素浓度和肝脏特征没有影响。日粮中BSFL浓度的增加使胸肉中的肉豆蔻酸浓度呈线性增加（P < 0.01），二十碳五烯酸浓度呈线性增加（P < 0.05）。这些结果表明，日粮中添加BSFL对免疫器官重量、胸肉品质和胸肉脂肪酸组成具有积极影响。因此，BSFL可作为肉鸡的饲料原料。此外，我们建议日粮中添加1%的BSFL可提高肉鸡的性能和健康水平。
