Sažetak
Performance test is the basic way of bleeding values estimation of potential sires. Total of 200 Large White young boars were tested by the performance test weighing from 28 to 101 kg of live weight during 84 days. The young boars were kept individually and fed ad libitum. At average final age of 171.92 days the young boars achieved average daily weight gain 0.90 kg, feed conversion 2.50 kg and fat thickness 13.99 mm. Significant phenotypic correlation (r) was found out between relevant fattening traits: daily weight gain: feed conversion = 0.669, daily weight gain: daily feed consumption = -0.530, daily weight gain: fat thickness = -0.177, daily feed consumption: feed conversion = 0.813, feed conversion: fat thickness = 0.190. Significantphenotypic correlation and relative indicators variability of fattening indicate possibility of further selection progress. Pig productivity in a herd may be significantly improved by using reproduction boars with more than 100 index points.
