摘要
我国畜牧业饲料原料特别是蛋白饲料短缺问题日益严峻,开发新的昆虫蛋白饲料具有较高的现实意义。研究通过测定赣南某稀土尾矿养殖的东亚飞蝗粗蛋白、17种氨基酸、铜、锌、总砷的含量,分析其营养成分,并与鱼粉进行比较评价其开发畜禽蛋白饲料的潜在价值。结果显示:以在赣南某稀土尾矿上种植的象草为食养殖生产的东亚飞蝗营养成分显著高于山东苏禾等地区养殖的东亚飞蝗,且不存在重金属含量超标的问题。研究对于赣南稀土尾矿上种植象草并养殖蝗虫,利用蝗虫开发畜禽蛋白饲料,提供了有价值的参考。
The shortage of animal feed materials,especially protein in our country has become increasingly severe,so the development of new insect protein feed has a high practical significance. In this study,the determination of crude protein,the content of 17 kinds of amino acid,copper,zinc,arsenic of Locusta migratoria manilensis breeded in Gannan rare earth tailings,were reserched. The nutrients of Locusta migratoria manilensis was analysised and compared with fish meal,in order to evaluate the development of the potential value of animal protein feed. The results showed that Locusta migratoria manilensis nutrients feeded in elephant grass grown in a rare earth tailings in Gannan,was significantly higher than other culture areas of Locusta migratoria manilensis such as Shandong Su Wo. And the content of heavy metal was lower than the national standard. The study can provide valuable reference for the Gannan rare earth tailing planting grass and breeding of locusts,locust development of animal protein feed utilization.
