Histological picture of the stomach of white rats during a subchronic study of the feed additive

Currently, most farms widely use modern feed additives as an additional Supplement to the main diet of animals. They are used in the form of concentrates, premixes, slime, which are necessary to increase productivity, accelerate growth and development, as well as prevent metabolic disorders in the body of animals. In this connection, the purpose of these studies was to study the effect of a new feed additive carbohydrate-vitamin-mineral concentrate "Lizunets" on the morphological characteristics of the stomach of white rats in a subchronic experiment. Experiments were conducted on white rats, divided into 4 groups. Animals in the control group were given distilled water, and the remaining 3 groups were given different doses of UVMC "Lizunets" in the form of an aqueous suspension for 30 days. At the end of the study, the experimental animals were killed under ether anesthesia in compliance with the rules of euthanasia. The thoracic and abdominal cavities were opened and organs were extracted for histological examination. It was found that during the use of the feed additive UVMK "Lizunets" behavioral reactions, water intake and feed did not differ from the groups of animals in the control group. The morphofunctional picture of the stomach tissue of white rats of the experimental groups of animals also did not differ in comparison with the histology of the stomach of the control groups of white rats.
