The work purpose - study of breeding situation and development system for collection of zootechnic information in the farms area to improve methods for assessing breeding value of swine. Research methods - zootechnical, biometric, analytical, statistical and economic. System of collection zootechnic information was exhaustid. Develfed methodical approaches for monitoring the reliability and completeness of the breeding material that will flow into the electronic database of breeding pigs. In controlled farms organized and estimation animals by traditional and BLUP method. Received new data on the level of development of the major breeding traits of pigs four breeds. Pigs for juveniles on average Ukraine selection indicator width lard was characterized by a significantly high negative correlation with BLUP index (r =-0,80 ***) and an estimated index of Iv (r = 0,79 ***) as well as medium-and low-relative to other methods of estimation. The existence of reliable correlations of these signs with BLUP index (r =-0,33***. -0,40*** and 0,14 -0,26***), an index Iv (r =-0,88** -0,89 ** and 0,42*** ...0,32***), average values score (r = 0,64 *** -0,53 *** and 0,55***-0,76**) and rank (r = 0,97** ...0,95** and 0,65 ** ...0,68 ***). Rate estimation of BLUP method for young pigs was significantly correlated with indicators of the index, the mean values of rank and points. Based on research, has the effect of breeding herd of pigs breeds LWAS simultaneously on four grounds, three levels of selective pressure: 50%, 23 and 10%. A trend for an increase in pig breeding effekta increased selection pressure from 50 to 23% and thickness of back fat, based on average daily gain and age of 100 kg bive weight respectively, in 1,1; 2,5 and 2,0 times. Predictable value of BLUP breeding index paternal lines when 27% of pressure for juveniles breeding pigs breed LAS will provide, on average, for a generation, increasing average growth rate at 46 g, and decrease the thickness of the FAT to 0,9 millimeter. Set the cost of further growth, obtained by breeding animals on BLUP index paternal lines. At 23-27% of breeding pressure it became 36,4 UAH for pigs breed LAS and 22,5 UAH for - LWAS, per 1 head of young per year. Based on the results of the research work formed the regional database. It contains information on 7589 head breeding animals, including 7037 head replacements of 22 lines of boars (3745 head) and 50 families, pig (3292 head). Note: thresholds of credibility:* - Р >0,95; ** - Р >0,99; *** - Р> 0,999.
