摘要: 为评估常见的农业废弃物上饲养白星花金龟幼虫的可行性及将低价值的农业废弃物转化为高质量蛋白产品的潜力,本研究选取了常见的水稻秸秆、玉米秸秆、高粱秸秆、香菇菌棒4种农业废弃物以及70%水稻秸秆+30%羊粪、70%玉米秸秆+30%羊粪、70%高梁秸秆+30%羊粪、70%香菇菌棒+30%羊粪的混合物以及羊粪作为饲喂白星花金龟幼虫的基质,研究了不同秸秆处理对白星花金龟幼虫生长、转化效率和虫体营养组成的影响。结果表明,白星花金龟二龄幼虫对70%玉米秸秆+30%羊粪的转化效率最高,三龄幼虫对70%高粱秸秆+30%羊粪的转化效率最高;不同秸秆处理上饲养的幼虫粗蛋白含量无显著差异,70%玉米秸秆+30%羊粪上饲养的幼虫氨基酸和粗脂肪含量最高,显著高于其他处理组。综上所述,白星花金龟幼虫对玉米和高粱秸秆与羊粪的混配物有高效的转化能力,使用70%玉米秸秆+30%羊粪作为饲喂基质可以获得营养价值更高的幼虫虫体。本研究不仅为农业废弃物的资源化利用提供了一条新的途径,还有助于推动白星花金龟养殖业的发展,具有重要的理论和实践意义。

Abstract: To assess the feasibility of rearing Protaetia brevitarsis larvae on common agricultural wastes and their potential to convert low-value agricultural residues into high-quality protein products, we conducted an experiment with four typical agricultural wastes (rice straw, corn straw, sorghum straw, and shiitake mushroom spent substrate) as well as five composite substrates: 70% rice straw + 30% sheep manure, 70% corn straw + 30% sheep manure, 70% sorghum straw + 30% sheep manure, 70% shiitake mushroom spent substrate + 30% sheep manure, and pure sheep manure (served as a control). The impacts of different straw-based substrates on larval growth performance, feed conversion efficiency, and body nutritional composition of P. brevitarsis were investigated. The results showed that the second-instar P. brevitarsis larvae achieved the highest feed conversion efficiency on the 70% corn straw + 30% sheep manure substrate, whereas the third-instar larvae exhibited the highest conversion efficiency when fed with 70% sorghum straw + 30% sheep manure. There was no significant difference in crude protein content among larvae reared on different substrate treatments. The larvae fed the 70% corn straw + 30% sheep manure substrate had the highest contents of total amino acids and crude fat, which were significantly higher than those in the other treatment groups (P<0.05). In summary, P. brevitarsis larvae possess efficient conversion capabilities for the composite substrates of corn straw/sorghum straw and sheep manure. 70% corn straw + 30% sheep manure can be used as the rearing substrate to produce larvae with superior nutritional value. This study provides a novel approach for the resource utilization of agricultural wastes and contributes to promoting the development of the P. brevitarsis breeding industry, with significant theoretical and practical significance.
