| Summary: | Okara obtained by processing soy grown in the Amur region contains twice as much raw and digestible protein as the product produced in the Western regions of our country. According to zootechnical analysis, it contains a mass fraction of crude protein of 29.58% and the amount of digested protein of 266.22 g. Its unnormalized use as a protein Supplement during intensive fattening of pigs causes fatty dystrophy of acinar cells and infiltrative growth of adipose and connective tissue, degenerative degeneration of the endocrine part of the glandular epithelium of the pancreas. Observed in liver cirrhotic transformation and protein-fatty degeneration of hepatocytes In 12-duodenum of piglets us were diagnosed with moderate diffuse chronic atrophic duodenitis, which manifests as thinning of the mucosa, flattening of surface epithelium, reducing the number of crypts and villi. The results of histological studies of the main digestive glands (pancreas and liver), as well as the small intestine allow us to conclude that soy Okara from Amur producers has a negative effect on the morpho-functional state of the digestive system, and as a result, a decrease in the digestibility and digestibility of nutritional components of the feed.
