Susol R. Effectiveness of uniting modern gene pools of Ukrainian Large White (ULW-1) pigs and pigs of French selection.

The thesis is dedicated to examining effectiveness of cross breeding sows of Ukrainian Large white breed with boars of Large white breed of French selection (FLW) and to growth and development peculiarities of crossed young stock. It was indicated that reproductive, fattening and meat qualities increased. High precocity genetic potential of FLW pigs and heterosis effect contributed to shifting of crossed young stock intensive growth to early stages of ontogenesis. Crossed young stock body proportions changed in the direction of meat shapes improvement especially rear 1/3 of body. Strong father’s inheritance was defined by improved meat qualities of crossed young stock as a decreased lard thickness, fat content, expansion of “muscle eye“ square and enlargement of ham, higher meat content, thicker muscle fiber, higher tasting evaluation with equal slaughtering outcome and length of half-body, and also on increase of mass of almost all inner organs and endocrine glands
