Morphology of the digestive organs of mink when used in the feeding of the black lion fly

In the course of the studies, it was found that the addition of Black Lion fly larvae to the diet of young minks, the mass of internal organs tended to increase. Macroscopic examination of visual differences in the condition, color, consistency, shape and size of the internal organs between the control and experimental groups was not established. Morphologically, the structural and functional state of the internal organs corresponded to the species and age parameters for young minks. Histological studies have established that the introduction of Black Lion fly larvae caused activation and enhancement of the secretory activity of the fundic glands in the stomach, elongation of the villi of varying degrees of intensity in the jejunum, an increase in the number of goblet cells and an abundance of mucus, which indicates a positive effect of the feed additive.
