Research results on usage of DNA-markers (RYRI, FABP, ESRF18/FUTI) and other factors for industrial pork production were presented. It was determined that DNA-technologies let conduct interbreed crossing on industrial scale and get diverse (fat or meat, with different fat content) products, as well as increase pork production in general. The best variants of crossing combinations were pigs of the Belarus large white breed with Belarus meat and Dyurok, and also the Belarus large white breed with Landras and Dyurok. Research results showed, for in course of the whole period of breeding the daily average weight gain of hybrids of the large white with the Belarus meat and breeds Landras was higher than with the Estonian bacon on 25 and 18 g, respectively. Fattening of stores was finished at the period of achievement of body weight by 100-102,5 kg. The slaughter yield of meat products by groups (without intestinal fat) did not essentially differ and varied within 69,9 - 71,1%. There were noted no considerable distinctions in weight of internals (heart, lungs, kidneys, spleen, liver). Thickness of the salted pork fat at hybrids with animals of the Belarus meat breed was 1-2 mm lower than in other. The average meat yield of diverting weir was 61,9%, fat weight - 27,9%, bone weight - 10,2%. The organoleptic evaluation of beef-infusion broth quality showed that indicators of habit, aroma and taste and nourishing were at high level and compose 4,67; 4,59; 4,55 and 4,71 points, respectively. Tenderness, juiciness and taste of boiled meat also were at level 4,69; 4,76 and 4,87 points, respectively; fried meat - 4,57; 4,68 and 4,66 points
