An experiment conducted on 56 fatteners was aimed at determining the effect of compensatory growth and addition of linseed oil in the II period of fattening on their slaughter value and meat quality. On termination of the I fattening period (23-60 kg b.w.) carcasses of animals fed in that period with a restrictive diet (-25% of diet), as compared to those of animals fed semi ad libitum, were characterised by greater meatiness (p≤0.05), lower fat content of longissimus thoracis, smaller free drip as well as higher values of chewiness and hardness. After the re-alimentation period, in which the animals were fed semi ad libitum with mixtures containing 0 or 4% of linseed oil, the greatest meatiness was observed in the pigs fed with a restrictive diet in the I fattening period and with a mixture containing 0% of linseed oil in the II fattening period. The restrictive-compensatory feeding strategy was found to exert a positive effect on contents of dry matter and total protein in longissimus thoracis and to have a negative impact on texture parameters of longissimus lumborum. The addition of linseed oil to feed mixtures caused a decrease in carcass meatiness (p≤0.05) and an increase in meat springiness (p≤0.05).
