Study on the Processing Technology of Fresh Duck Manure and Insect Feed and Insect Sand by Hermetia illucens
In order to study the effect of Hermetia illucens on duck manure treatment,Hermetia illucens was used as the research insect and fresh duck manure was used as the treated object.Several key process parameters of Hermetia illucens treatment of duck manure were studied,and nutritional analysis and evaluation of Hermetia illucens larvae and insect sand were also conducted.The experimental results showed that the optimal moisture content for feeding Hermetia illucens with duck manure was 79.16%,and the utilization rate of transformed duck manure(duck manure/fresh insect)is 4.15.The economic benefits are worth promoting and utilizing;The optimal conversion state is to maintain the material temperature in the feeding pool at 38～40℃;The quality content of crude protein(CP)in the larvae was lower than that in the second grade fish meal(CP 53.50%)and the special grade soybean meal(CP 44.20%);Rich in amino acids,the total amount of amino acids is higher than that of soybean meal but lower than that of fish meal;The organic matter content of the insect sand is 70%,and the total nutrient content is 9.5%.The pH,roundworm egg mortality rate,total arsenic,and total lead all meet the national organic fertilizer standards.
