Transformation of pig manure by black soldier fly and its application in piglet production
Currently,using pig manure to cultivate black soldier flies can simultaneously achieve the goals of pig manure re-source utilization,reduction,and harmless treatment.In order to expand the types and sources of animal protein feed materials for pigs,the study first fed black soldier flies with pig manure to prepare black soldier fly powder.Afterwards,black water fly powder was used instead of fish meal to design a feed for piglets,and the application value of black water fly powder as piglet feed was analyzed.The results showed that the apparent digestibility of crude protein nutrients of the control group in the piglet feeding ex-periment was 66.10%,while experimental group 1 and experimental group 2 increased by 4.06%and 4.95%with a p value of 0.01.The use of black soldier fly meal as a partial or complete replacement for fish meal in experimental group 1 and 2 signifi-cantly improved the digestion and absorption rate of crude protein.This helps to reduce the production cost of piglets and ensure the sustainable development of pig farming.At the same time,it provides certain reference for the application of black soldier flies in piglet production in the future.
