在Scopus进行的文献检索中,总共确定了23项研究,用于荟萃分析的ScienceDirect和GoogleScholar数据库。所使用的标准包括2015年至2023年发表的研究,以及报告昆虫粉在家禽饮食中的影响的研究。活重数据(LW),car体重量(CW),水分,肉类pH值,亮度(L*),发红(a*),黄色(b*),最接近的成分(蛋白质,肉仔鸡的脂肪和灰分含量)和剪切力采用OpenMEE软件,和数据使用随机效应模型进行汇总。进行了亚组分析和荟萃回归,以确定饮食昆虫膳食对肉类方面的反应和异质性来源的影响,分别,使用以下主持人(昆虫物种,剂量水平,屠宰时的喂养时间和年龄)。结果表明,膳食昆虫粉不影响LW,CW,肉L*,pH值,剪切力,水分,脂肪和灰分含量。相比之下,饮食中的昆虫粉增加了肉的a*(标准化平均差(SMD)=1.03;95%置信区间(CI)=0.484-1.578;p≤0.001),b*(SMD=1.117;95%CI=0.334-1.90;p=0.005),和肉蛋白质含量(SMD=0.365;95%CI=0.031-0.7;p=0.032)。亚组分析表明,≤10%的昆虫粉剂量和屠宰≤35天的年龄改善了LW,CW和肉L*。此外,肉a*,蛋白质和灰分含量也受昆虫种类的影响,屠宰时的剂量水平和年龄。总之,≤10%的隐虫或黄粉虫可以包含在肉鸡饮食中,而不会损害LW,CW,肉类pH值,颜色,剪切力,水分,肉仔鸡的脂肪和灰分含量。因此,研究表明,昆虫餐作为家禽日粮中的替代蛋白质来源具有广阔的前景。
A total of 23 studies were identified in a literature search performed in the Scopus, Science Direct and Google Scholar databases for meta-analysis. The criteria used include studies that were published from 2015 to 2023 and those reporting the effects of insect meal utilisation in poultry diets. Data on live weight (LW), carcass weight (CW), moisture, meat pH, lightness (L*), redness (a*), yellowness (b*), proximate composition (protein, fat and ash content) and shear force in broilers were subjected to OpenMEE software, and data were pooled using a random-effect model. Subgroup analysis and meta-regression were performed to ascertain the influence of dietary insect meals on the response of meat aspects and the source of heterogeneity, respectively, using the following moderators (insect species, dosage level, feeding duration and age at slaughter). The results indicated that dietary insect meal did not affect LW, CW, meat L*, pH, shear force, moisture, fat and ash content. In contrast, dietary insect meal increased the a* of the meat (standardised mean differences (SMDs) = 1.03; 95% confidence intervals (CIs) = 0.484-1.578; p ≤ 0.001), b* (SMD = 1.117; 95% CI = 0.334-1.90; p = 0.005), and meat protein content (SMD = 0.365; 95% CI = 0.031-0.7; p = 0.032). The subgroup analysis showed that insect meal dosage of ≤10% and age at slaughtered ≤35 days had improved the LW, CW and meat L*. In addition, the meat a*, protein and ash content were also influenced by insect species, dosage levels and age at slaughter. In conclusion, ≤10% of either Hermetia illucens or Tenebrio molitor can be included in broiler diets without compromising the LW, CW, meat pH, colour, shear force, moisture, fat and ash content in broilers. The study therefore indicated that insect meals have a bright future as an alternative protein source in poultry diets.
