Sixteen Prestice Black-Pied pigs were divided into two groups and fed control diet (group C) and diet with 7 % of linseed addition (group L). The experiment started three months before slaughter. The intake of feed mixture and water was ad libitum. The average final live weight was 114.13 +/- 10.09 kg (C group) and 110.00 +/- 9.46 kg (L group). The carcass value and growth parameters (daily weight gain, lean meat content and backfat thickness) and meat quality (drip loss, intramuscular fat content, cholesterol content and meat colour values - L* lightness; a* redness; b* yellowness ) were determined. The carcass value was not affected by linseed addition into feed mixture. Intramuscular fat content was decreased in linseed fed pigs (1.94 +/- 0.37 %) compared to control group (2.32 +/- 0.71 %). There were no statistically significant differences in drip loss parameter between groups (2.37 +/- 0.34 % in C group, 2.51 +/- 0.29 % in L group), colour parameters and cholesterol content (74.68 +/- 3.13 mg in C group, 77.36 +/- 6.91 mg in L group). Addition of linseed to feed mixture for fattening pigs can increase lean meat content but together with this improvement the decrease of intramuscular fat below recommended level (2.5 %) is monitored.
