In the conditions of the Republic of Belarus on the basis of modern selection methods there were realized works on creation of selective sow herds of the Belarusian Large white breed in the amount of 2000 heads with the following productivity indexes: multiple fetation – 11,5 piglets; age of 100 kg achievement – 180 days; average daily weight gain – 770 g; feed consumption – 3,4 fodder units per 1 kg of weight gain; fat depth – 25 mm; pestle of pork weight – 11,0 kg. Results of selection of Belarusian Large white breed for the period of 2007-2010 are analyzed. Positive dynamics of pedigree animals development is determined, stable tendency of increase of reproductive, fattening and meat traits was determined. So multiple pregnancy for the period increased at 0,15 piglets (or 1,4%), the average daily weight gain at fattening - at 26 g (or at 3,5%), hock weight - at 0,3 kg (or 2,8%). The total profit for the period made 23,45 mlrd. of Belarusian rubles.
