Abstract: Soya takes one of leading place in the balance of protein fodder cultures and in its grain there is a high contains of protein. Its amino acids composition is the most approximate to feed-staffs of animal origin. Considerable percent of sowing areas are allocated under high-yielding and technological genetic-modified lines of soya which is used in pig breeding field. Results of researches in reference its influence on the organism of agricultural animals is ambiguous and contradictory. So, it is prompted the certain interest to study the long-term influence RR lines of GM-soya on the organism of pigs as a model object for its physiology which is approximate to people. The aim of researches was the study of the influence of identified (RR, GTS 40.3.2) of genetic-modified lines of GM-soya on the intensity of growth, the quality of boar sperm and the reproductive ability of sows. Researchers are carried out on the base of state enterprise “Experimental base “Nadiia” of Institute of Pig Breeding and AIP NAAS. The live-stock of pigs analogs of the Poltava Meat breed in number of 24 heads (8 gilts and 4 young boars in every group) was used. The diet for pigs of a control group consists of 10 % for mass of full fat extruded soya without GMO and researched one – GMO, lines RR GTS 40.3.2. During rearing period of sows’ livestock the average daily gains in experimental group (GMO) were lower than in control group without GMO and were 583.13±28.62 g та 626.12±13.96 g accordingly. In researches it was determined that the volume of ejaculate of boar sperm in a control group was higher on 32.4 % (227.6 cm3 against 171.9 cm3), but for indexes of the concentration of spermatozoa was lower on 21.17 % (P=0.046). Increasing the number of active spermatozoa in ejaculate of control boars on 1.9 billion gave the possibility to get additional number of sperm doses. The polycarpous of sows which consumed soya without GMO was higher on 44.2 % (10.57 heads of piglets against 7.33, P=0.03). Average daily gains of piglets and accordingly their live weight at weaning were probably (P=0.011) higher in control group. So, using GM-soya as a protein fodder addition a little influenced in the negative on the development of animals and reproductive function of sexual organs of boars and sows.
