1. Study on the Application of Black Water Gadfly larvae in the Feed of finishing Pigs

Dried black water gadfly larva powder can be used in the feed of piglets and fattening pigs. There was no repulsive feeding behavior for pigs with dried black water gadfly powder, and the feed intake of dried black water gadfly larva powder was significantly higher than that of soybean meal without additional oil (P0.05). Except for crude fat (ether extract), there was no significant difference in total apparent digestibility of nutrients between the two kinds of insect larvae (P > 0.05), but the total apparent digestibility of crude fat in black water gadfly larvae was significantly higher than that in yellow powder insects (P0.05). However, it could increase the dressing percentage, abdominal fat, leg muscle, chest muscle and chest muscle content of unsaturated fatty acids, and reduce the content of saturated fatty acids (P > 0.05).

two。 Study on the application of black water gadfly larva in layer feed

Compared with the control group, the egg laying performance was improved by adding black water gadfly larva (P > 0.05), and the feed intake was increased by adding 12% black water gadfly larva feed (P > 0.05), but had no significant effect on the health status of laying hens (P > 0.05).

(3) study on the application of black water gadfly larva in quail quail feed

1. Study on the application of black water gadfly larva in meat quail feed

Black water gadfly larva powder could partially replace soybean meal and soybean oil in quail feed during growing period, and there was no significant difference in dry matter, crude protein, starch, intake preference and apparent digestibility of energy among the experimental groups (P > 0.05). There was no significant difference in microbial composition, chest muscle weight and egg production among the experimental groups (P > 0.05). Production performance, mortality and carcass traits were all in line with commercial standards, and there was no significant difference among the experimental groups (P > 0.05).

two。 Study on the Application of Black Water Gadfly larvae in Egg Quail Feed

Partial replacement of fish meal with black water gadfly meal had a significant effect on feed feeding rate, feed efficiency and egg weight (P0.05). The egg feed consumption of quail in 100% black water gadfly maggot meal group was less than that in 100% fish meal group. Compared with the control group, the quails fed with black water gadfly larva feed showed better production performance and egg laying performance. The growth performance and egg laying performance of quails fed with 25% black water gadfly larvae + 75% commercial feed were the best.
