Abstract

This article uses the results of a comparative morphological study in the digestive system organs of experimental and control groups of turkey broilers of heavy crosses when using the probiotic feed additive Bacell-MT. The experiments were conducted at the Ural Federal Agrarian Research Center. Ural Branch of the Russian Academy of Sciences” and at the Department of Morphology and Expertise of the Ural State Agrarian University in 2024. The use of the probiotic feed additive Bacell-MT in the diet of turkey broilers did not lead to negative changes in their general condition, survival rate, or the structure of the digestive system.During the histological analysis of the digestive system organs of turkey broilers of the control group, including the liver, pancreas and duodenum at the age of 105 days, we identified processes characteristic of inflammation, which manifested themselves in the duodenum in the form of mucous catarrh, in the liver and pancreas in the form of proliferative processes in the wall of blood vessels. At 206 days of age, we visualized normalization of inflammatory processes in the experimental group of birds, especially in the liver, and an increase in the body’s local immunomorphological response in the form of an increase in the number of lymphoid follicles in the duodenum and activation of beta cells in the pancreas.
