Evaluation of the effects of soybean meal replacement fly larvae (Hermetia illucens) in Arian broilers

This experiment was performed to investigate the effect of different levels of fly larvae with soybean meal as a source of in protein in broilers (male and female) in Arian broilers with 440 birds in a completely randomized design with four treatments, five replications and 22 birds per replication (male and female equally). The treatments used in this experiment included: treatment one (control diet), treatment two with 10% larvae substitution diets instead of soybean meal, treatment three with 20% substitution diets instead of soybean meal and treatment four with 30% substitution diets in soybean meal substitute composition. The duration of the experiment ranged from one to 45 days. Which was given to them for a week before the start of the experiment to get used to the basic diet. The birds were fed from the eighth to the 18th day of the initial feed, from the 19th to the 30th day of the growth feed and also from the 31st to the 45th day with the final feed. The results of this study showed that the performance of broilers was not affected by experimental treatments (P<0.05) so that the treatment containing 20% ​​of fly larvae had the highest live weight and the lowest weight of heart, liver and gizzard, also in treatment 20 and 30% of larvae had the highest carcass weight and the control treatment had the highest amount of abdominal fat. In general, it can be concluded that the addition of fly larvae improves the performance and carcass characteristics in Aryan broilers and can be used as a substitute for soybean meal in the diet chickens. Economically, European production efficiency factor in treatments including the fly larvae (Hermetia illucens) is better than soybean meal. However, the recommendation to use fly larvae requires a more accurate economic calculation.
