Abstract:
This paper aimed to investigate the optimization of Gryllus assimilis farming production by examining the effects of replacing soybean meal with rapeseed cake (25-100%) and supplementing it with rapeseed oil. The results reveal no adverse effects of soybean meal replacement on the feed conversion ratio and weight of the harvested crickets. However, incorporating larger quantities of rapeseed cake into the diet increased crude protein and decreased fat content. Moreover, the composition of fatty acids varied significantly, with increased levels of oleic acid and decreased levels of palmitic acid, while a high rapeseed cake content led to a decrease in the atherogenic and thrombogenic index values. The amino acid composition remained unaffected. In conclusion, the study demonstrates that rapeseed cake can serve as a viable substitute for soybean meal in the diet of Gryllus assimilis.
摘要:
本文旨在通过研究用菜籽饼(25-100%)代替豆粕并补充菜籽油的效果来研究Gryllus同化是农业生产的优化。结果表明,豆粕替代对收获的the的饲料转化率和重量没有不利影响。然而,在饮食中加入大量的油菜籽饼会增加粗蛋白并降低脂肪含量。此外,脂肪酸的组成差异很大,随着油酸水平的增加和棕榈酸水平的降低,而高菜籽饼含量导致动脉粥样硬化和血栓形成指数值降低。氨基酸组成保持不受影响。总之,该研究表明,油菜籽饼可以在Gryllusassimilis的饮食中作为豆粕的可行替代品。
