  Abstract
  This research focuses on the reproductive qualities of cross-breeding sows of different breeding options, growth rate and development of hybrid piglets during periods of suckling and nursery, and on the assessment of fattening and meat qualities with different genotypes. The best reproductive performance was observed when crossing crossbred sows (LW x L) with Duroc boars: multiple fertility reached 14 baby piglets, the weight of a piglet 1.6 kg, livability up to weaning 93.8%, live weight before weaning 6.5 kg. Hybrid piglets from the first and second groups were characterized with the best growth rate during suckling and nursery periods; they were obtained from a combination of sows of Large White x Landrace of Canadian and Danish breeding with Duroc boars. Best results in fattening and slaughter qualities of hybrid young animals were obtained with a combination of sows (LW x Y) with Canadian Landrace boars, and also with a combination of sows (LW x Y) with Danish Landrace boars: early maturity 145-146 days, average daily gain 990.4 g, slaughter yield 80.9% and 79.6%, respectively. The length of the carcasses of young animals of the third group in this experiment was larger in comparison to their herd mates in the second and first groups, respectively. Piglets from the second group (LW x L c.) xD had the smallest fat depth, and fattening livestock from the third and fourth groups had the largest one; these animals also had a higher pre-slaughter weight. Fat depth in the second (LW x L c.) xD group was less, compared to the third and the fourth groups. According to research results, for increasing the production of pork and for improving its quality under industrial conditions, it is recommended to use Canadian and Danish Landrace boars at the final stage of crossbreeding in a three-breed combination i.e., Large White x Yorkshire x Landrace.
