بررسی اثرات جایگزینی لارو مگس (Hermetia illucens) با کنجاله سویا در جوجه های گوشتی نژاد آرین

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 ۴۴۰ birds in a completely randomized design with four treatments, five replications and ۲۲ birds per replication (male and female equally). The treatments used in this experiment included: treatment one (control diet), treatment two with ۱۰% larvae substitution diets instead of soybean meal, treatment three with ۲۰% substitution diets instead of soybean meal and treatment four with ۳۰% substitution diets in soybean meal substitute composition. The duration of the experiment ranged from one to ۴۵ 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 ۱۸th day of the initial feed, from the ۱۹th to the ۳۰th day of the growth feed and also from the ۳۱st to the ۴۵th day with the final feed. The results of this study showed that the performance of broilers was not affected by experimental treatments (P<۰.۰۵) so that the treatment containing ۲۰% ​​of fly larvae had the highest live weight and the lowest weight of heart, liver and gizzard, also in treatment ۲۰ and ۳۰% 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.
