It has been researched the digestibility of nutrient matter of mixed feed-stuff in fattening young pigs of the Poltava meat bread which included soya feed-staff, made at different technologies (expanding, spinning under pressure, extrusion) in a comparative aspect with sunflower meal. It was used such methods: zootechnical, physiological (balance) method of groups at individual holding animals in metal cages on a background scientific and economic experiment, chemical, statistical. The presence in mixed feed-stuff of plant protein feed-stuff of different technologies of the production in the diet affected on the average daily consumption by animals of nutrient matters of feed-stuff. The chemical composition and average daily number of selected feces and urine was researched. Significant difference in chemical composition of excrements between pigs of experimental groups it was found out for the number of nitrogen free extractive matters, fat and cellulose. Installed significant difference greater excretion of fat in the feces of the first experimental group animals by 36.5% (p≤0.01), and smaller — cellular tissue to 20.93% (p≤0.01); and 39.82% (p≤0.001) in the first and third experimental groups compared. In all experimental groups the tendency is observed to increase digestibility coefficients of crude protein, crude ash and nitrogen free extractive matters. The higher coefficient of digestibility of crude protein compared with control was in pigs of the third experimental group whose diet included soya extrudate. The digestibility of crude fat was significantly better in the animals of the third experimental group compared to the first and was 61.02% vs. 49.64% (p≤0.05) accordingly. The high digestibility of main nutrient matters of feed-stuff provided average daily gain of pigs of experimental groups at the level of 857–952 g, which is higher than the control at 5.93–17.68% (p≤0.05) according.
