摘要
昆虫是一种优质饲料原料,其中黑水虻幼虫在提供饲用蛋白质及油脂的基础上还具有特殊的功效。本试验利用有机废弃物中药渣养殖黑水虻,通过控制每克卵获得不同重量的中药渣(5、7、10、11、13、16、20 kg),计算比较养殖12 d后的鲜虫增重和料重比,以确定最佳中药渣投喂量。幼虫生长曲线测定以猪饲料为对照组,每2~3 d随机抽样称重,拟合生长曲线,并计算拐点体重、拐点日龄及快速增长期。幼虫的营养成分及安全指标根据国标进行检测,结果表明:最适投喂量为每克虫卵10~13 kg中药渣。中药渣养殖的黑水虻快速生长期为第4~15天。幼虫干物质中粗蛋白质含量为35.1%,粗脂肪含量为37.1%。所检测安全指标均符合国家饲料卫生标准。
Insect is a kind of high quality feed sources.The black soldier can provide forage protein and fat,but also has special efficacy.This paper aims to establish a black soldier fly rearing method by using herbal waste.The herbal waste ration was varied from 5 kg to 20 kg per gram of egg.After 12 days feeding,the larval weight gain and the feed conversion ratio were compared to determine the optimal feeding amount.Then the growth curve of black soldier fly larvae fed on herbal waste was drawn with pig feed as the control diet by weighing every 2 -3 days.The larval nutrient content and safe-ty indexes were determined.The results showed that the optimal feeding amount was 10 ？13 kg herbal waste（water content 87.81%）per gram of egg.The fast growth period was 4 to 15 days.The crude protein content of larvae was 35.1% and crude fat comtent was 37.1%.The safety indexes was up to the criterion in China hygienically standard for feeds.
