THE CHEMICAL COMPOSITION AND PHYSICAL-CHEMICAL PROPERTIES OF MUSCLE AND ADIPOSE TISSUE OF PIGS PROVIDED THE USE OF SOYBEAN PROTEIN FODDER

Abstract

The results of the chemical composition and physico-chemical properties of the muscle and adipose tissues of pigs fed on the diets with soya protein feed of different technologies are given: expansion as the pressure (soy protein concentrate, dry fodder – KSBSK), extraction under pressure (soybean cake), extrusion (soy extrudate). Sunflower cake is used as a control. It was found that the chemical composition and physico-chemical properties of muscle and adipose tissue of all experimental groups of pigs are at the level of normative parameters, indicating high quality pork. In the process of comparing quality indicators between the groups of analogues significant difference has not been established. However, in the muscle tissue of animals that are fed on KSBSK, the tendency of increase in the dry and organic matter, protein and energy content was observed.
