Effect of vitamin-mineral complex with probiotic on histological structure of gastrointestinal tract tissues of budgerigars

Purpose: to evaluate the effect of a vitamin-mineral complex with a probiotic on the histological structure of the gastrointestinal tract tissues of budgerigars in dynamics.

Materials and methods. The object of the study were budgerigars aged from 60 to 180 days. According to the principle of pairs-analogues, 3 experimental and a control group of 20 birds each were formed from clinically healthy budgerigars. For the purpose of the experiment, complete granules were created containing a basic grain-seed diet and a complex consisting of a probiotic, vitamins and minerals. Bacillus Subtillis 5 mg per 100 g of live weight was used as a probiotic. For histological and histochemical studies, tissue pieces measuring 0.5 x 0.5 x 0.5 cm were selected. In each section, an assessment of at least 10 fields of vision was given.

Results. As a result of the experiment, lasting 45 days, a gradual increase in the probiotic mass was noted in the gastrointestinal tract of budgerigars on the 15th and 30th day. Complete release of the body from the probiotic was observed on the 30th day after stopping the administration of the granulated complex. No changes in the histological structure of the liver were revealed. Positive changes in the intestine and stomach were noted, such as an increase in the density of villi and the height of the epithelium, folds, crypts and tubular glands. These changes are reversible, due to the temporary effect of the vitamin and mineral complex with a probiotic.
