Effects of substitution of fish meal with fresh and dehydrated larvae of the house fly (Musca domestica L) on productive performance and health of broilers

Abstract

In order to investigate the effects of substitution of fish meal with fresh and dried housefly larvae (Musca domestica L) on productive performance and health status of broilers a study was conducted on a poultry farm in the vicinity of Belgrade. Two hundred Hybro-G broilers, of both sexes, originating from the same parent flock, of standardized body mass, were divided into four equal experimental groups. The experiment lasted 42 days. The control group (C) was fed standard diets. The broilers of the first and second experimental groups (O-I and O-II) were fed diets in which 50%, and 100%, fish meal had been substituted with housefly larvae meal (HLM). The third experimental group (O-III) was fed diets without fish meal, but supplemented with no fresh larvae in special feeders. The chemical analysis showed that dehydrated HLM contained 59.48% dry matter (DM) protein; whereas fresh larvae, prepared by a special technological method, contained 59.10% DM protein; whereas fish meal contained 67.39% DM protein. Viewed in total, the obtained productive results for the experimental groups (O-I, O-II, O-III) were approximately the same as those for the control group (C); whereas the results obtained per phase show statistically significant differences, due to the influence of the applied treatments (p<0.05; p<0.01). The fresh and dehydrated larvae, used as substitutes for fish meal, had a positive effect on productive performance and health status of broilers, which provides a good possibility for using them in diets intended for feeding broilers

Sequential Extraction and Characterisation of Lipids, Proteins, and Chitin from Black Soldier Fly (Hermetia illucens) Larvae, Prepupae, and Pupae

“…Several studies describe the protein and lipid composition of larvae and prepupae reared on different organic substrates. It is known that, depending on the rearing conditions, black soldier fly larvae contain protein and fat quantities on dry matter basis ranging from 35 to 57 %, and from 15 to 49 %, respectively [2,[4][5][6][7]. Not only the amount of fat but also the fatty acid composition of the larvae depends to a great extent on the composition of the diet [8,9].…”

Mealworm (Tenebrio molitor) rearing and growth optimization as a sustainable food source using various larval diets under laboratory conditions

“…Fresh housefly maggots given to broiler chicks resulted in greater body weight, average daily weight gain, and average daily feed intake (Grau et al., 2017). Furthermore, supplementing free‐range hens with live maggots enhanced their growth rate, clutch size, egg weight, hatchability, and chick weight while decreasing fearfulness in young pullets (Đorđević et al., 2008). Recent research found that broiler chickens, Japanese quails, and Barbary partridges fed a diet including dried mealworms had drastically enhanced growth performance, blood profile, and meat quality (Józefiak et al., 2007; Elahi et al., 2020).…”
