The results of estimation of breeding value for Large White and Poltava meat pig breeds in breeding farms of the region by cost-effective methods are presented, namely: combined assessment of repair young stock on person’s productivity, estimation indices of fattening and meat qualities and new method BLUP. The best indicators for assessing the breeding value of animals were found on the basis of using the modern, most promising method BLUP, as it is considered the most accurate. The average value of the BLUP index (parent lines) for boars of Large White breed is 101.71±1.681, pigs – 96.94±0.724 points and Poltava meat breed, respectively, 106.23±2.167 and 93.65±0.719 points. The most positive correlation between live weight of piglets at weaning with their body length (r=0.16), average daily gain (r=0.19) and fat thickness (r=0.24), average correlation between the indices of fattening and meat qualities according to Berezovskyi M.D. and Tailer B. (r=0.56) P>0.99 and a weak correlation between live weight of piglets at weaning and the BLUR index (r=0.21) P>0.99.
