Abstract

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.

Highlights

In the pig industry, there is a constant problem of lack of protein and amino acids in the diet of fattening young animals
A large amount of protein and free amino acids contained in soy Okara can have a negative impact on the functional and morphological state of the digestive organs of farm animals and thereby reduce their productive qualities, especially when used abnormally. [5]
The purpose of our work is to study the morphological changes in some digestive organs of young pigs and cattle when using soy Okara as a protein Supplement

Summary

Introduction

There is a constant problem of lack of protein and amino acids in the diet of fattening young animals. Feeders often use soy and its processed products such as soy meal, cake, and flour to balance their protein diets. As an additional source of protein, many farms in the Amur region that specialize in fattening pigs and cattle use the product of soy processing – Okara. Okara almost does not contain fat, but it contains a lot of fiber Summarizing the results of research by domestic and foreign authors on the chemical composition of soy Okara dry matter, it can be presented as follows: the protein content ranges from 5.3 to 32.2%, fat — from 3 to 22.2, dietary fiber — from 6.75 to 58.1%
