This thesis has presented the results of two experiments. The first experiment tested the effect of usage of crude soybean on productive characteristics during 140 days. The experiment included 36 pigs of the initial weight of about 23 kg, which were sorted into three different groups depending on the composition of diet. The difference of diet consumed by pigs was reflected in 14% of crude or heat-treated whole soybean with different sorts of soy. The results of this experiment show that usage of raw soybean grain in nutrition of fattened pigs leads to statistically justified reduction in pig weight and daily growth. Pigs which had diet which included raw soybean grain of Lana sort had worse feed conversion as well. In the second experiment, we tested the effect of usage of crude soybean for nutrient matter digestion, during 30 days, for each of 4 recurrences. The experiment involved 16 pigs with initial weight of 70 kg, sorted into 4 groups depending on their diet composite. In the first group diet included heat-treated standard sort of soybean grain, while the second group diet included heat-treated grain of soybean sort Lana, the third group diet included raw soybean grain of standard sort, and the fourth group diet included raw soybean grain of Lana sort. The first group of pigs was fed by diet contained heat-treated grain of soybean, which served as a control group. The results of this experiment show that usage of raw soybean grain in nutrition of fattened pigs leads to statistically justified reduction of digestible proteins, digestible lipids and BWFP. Usage of raw soybean grain of standard sort in pig nutrition did not give adequate results, which was expected. However, unexpectedly poor productive results and somewhat lower level of digestibility of Lana soybean sort can be explained by the absence of the real effect.
