Abstract

The article presents the results of studies aimed at studying the effect of domestic feed additives based on a 55 % water-oil emulsion of fish oil and flaxseed oil (Manufacturer: LLC Firm "A-BIO") on the histomorphological parameters of muscle tissue and internal organs (liver, spleen) of laying hens. It is worth noting that the use of drugs and feed additives in livestock and poultry farming can have both positive and negative effects on the animal’s body as a whole. Carrying out histomorphological studies of the muscle tissue and internal organs of birds after the use of feed additives will allow us to assess the degree of their impact on the body of laying hens. It has been established that domestic feed additives used in poultry diets do not have a negative effect on the histomorphological parameters of muscle tissue and internal organs (liver, spleen) of laying hens.
