日粮辣度对黑水虻幼虫生长性能、转化率和减废指数的影响OA北大核心CSTPCD

Black soldier fly larvae have good application prospects in the resource utilization of kitchen waste.To investigate the effect of spiciness on the growth of black soldier fly larvae,seven different spici-ness gradient diets(capsaicin concentration of 0,0.2,0.4,0.6,0.8,1.0 and 1.2％)were fed to 7-day-old black soldier fly larvae in this study.The results showed that the feed to gain ratio of the 0.8％capsaicin group was significantly lower than that of the 0.6％capsaicin group(P＜0.05),but there was no signifi-cant difference with other groups.The larvae in the 0.8％capsaicin group had the lowest dry matter con-tent and were significantly lower than those in the 0.6％and 1.2％capsaicin groups(P＜0.05).There were no significant differences in other indicators such as growth performance,survival rate,conversion rate and waste reduction index of black soldier fly larvae(P＞0.05).The results showed that the 0.8％capsai-cin group had the least nutrients converted from feed,and the 0.6％capsaicin group had the lowest conver-sion efficiency.Therefore,the larvae of black soldier fly show great tolerance to spiciness,and the results of this study will provide basic data for black soldier fly larvae in the resource utilization of kitchen waste.
