Abstract

The recycling of minerals is crucial for the future circular agriculture. Black soldier fly larvae (BSFL) can accumulate minerals in their body. This study investigated the effects of adding mineral-enriched BSFL, grown on substrates containing sewage sludge recyclates (SSR), to broiler feed to reintroduce minerals from waste streams currently subject to regulatory restrictions back into the nutrient cycle. Feed, nutrient, mineral and heavy metal intake, growth, blood metabolites and immunoglobulins, bone characteristics and mineral status of broilers were studied in response to different mineral-enriched BSFL supplements. Eighty newly-hatched mixed-sex Ross 308 chicks were divided into four groups, with six replicate pens per group. BSFL used in the broiler experiment were grown either on a modified Gainesville fly diet (FD) (L-FD) or on FD supplemented with 4% of sewage sludge biochar (L-BCH), or on the FD supplemented with Single Superphosphate (SSP) SSR (L-SSP). All broilers were fed age-specific diets and either had no access to BSFL (CON) or received 15% of CON birds’ feed intake as defrosted BSFL from three different sources. Inclusion of 15% of mineral-enriched whole BSFL in broiler rations had no adverse effects on growth performance parameters, nutrient intakes, nutrient conversion efficiency, plasma metabolites and immunoglobulins (). Birds in BSFL supply groups had higher serum Ca concentrations than CON birds (). L-BCH supplied birds had a lower serum P than CON birds (). Tibial characteristics and mineral status of birds were not affected by larvae supply (). Heavy metal intake (manganese, iron, zinc, copper, arsenic, cadmium, lead, and mercury) of the birds was not affected by dietary treatments (). In conclusion, 15% of mineral-enriched-BSFL reared on SSP can be included in broiler diets for 42 experimental days without adverse effects on nutrient intakes, growth performance parameters and bone condition.

摄入富含矿物质的全黑兵蝇幼虫饲料的肉鸡的生长、营养吸收、血液代谢物和骨骼特性

矿物质的循环利用对未来的循环农业至关重要。黑实蝇幼虫（BSFL）可以在体内积累矿物质。本研究调查了在含有污水污泥回收物（SSR）的基质上生长的富含矿物质的 BSFL 添加到肉鸡饲料中的效果，以便将目前受监管限制的废物流中的矿物质重新引入营养循环。研究了不同富含矿物质的 BSFL 补充剂对肉鸡的饲料、养分、矿物质和重金属摄入量、生长、血液代谢物和免疫球蛋白、骨骼特征和矿物质状态的影响。80 只刚孵出的罗斯 308 混性别雏鸡被分为四组，每组六个重复栏。肉鸡实验中使用的 BSFL 是在改良的盖恩斯维尔苍蝇日粮（FD）（L-FD）或添加 4% 污泥生物炭的 FD（L-BCH）或添加单过磷酸钙（SSP）SSR 的 FD（L-SSP）上生长的。所有肉鸡都饲喂特定年龄段的日粮，或者不摄入 BSFL（CON），或者从三种不同来源摄入占 CON 鸡采食量 15%的解冻 BSFL。在肉鸡日粮中添加 15%的富含矿物质的全 BSFL 对生长性能参数、营养摄入量、营养转化效率、血浆代谢物和免疫球蛋白（）没有不利影响。供应 BSFL 组的肉鸡血清钙浓度高于供应 CON 组的肉鸡（）。L-BCH供应组的鸟类血清中P含量低于CON组（）。鸟类的胫骨特征和矿物质状况不受幼虫供应的影响（）。鸟类的重金属摄入量（锰、铁、锌、铜、砷、镉、铅和汞）不受日粮处理的影响（）。总之，在肉鸡日粮中添加 15%的富含矿物质-BSFL（用 SSP 饲养）42 个实验日，不会对营养摄入量、生长性能参数和骨骼状况产生不利影响。

期刊介绍： The Journal of Insects as Food and Feed covers edible insects from harvesting in the wild through to industrial scale production. It publishes contributions to understanding the ecology and biology of edible insects and the factors that determine their abundance, the importance of food insects in people’s livelihoods, the value of ethno-entomological knowledge, and the role of technology transfer to assist people to utilise traditional knowledge to improve the value of insect foods in their lives. The journal aims to cover the whole chain of insect collecting or rearing to marketing edible insect products, including the development of sustainable technology, such as automation processes at affordable costs, detection, identification and mitigating of microbial contaminants, development of protocols for quality control, processing methodologies and how they affect digestibility and nutritional composition of insects, and the potential of insects to transform low value organic wastes into high protein products. At the end of the edible insect food or feed chain, marketing issues, consumer acceptance, regulation and legislation pose new research challenges. Food safety and legislation are intimately related. Consumer attitude is strongly dependent on the perceived safety. Microbial safety, toxicity due to chemical contaminants, and allergies are important issues in safety of insects as food and feed. Innovative contributions that address the multitude of aspects relevant for the utilisation of insects in increasing food and feed quality, safety and security are welcomed.
