The effect of diet supplementation with linseed scrap on the meat quality and fatty acid profile of the meat and backfat in fattening gilts

Popis výsledku v původním jazyce

The study was designed to evaluate the effect of diet supplementation with linseed on the carcass charac-teristics, meat quality and oxidative stability as well as the composition of the fatty acids in M. longissimus lumbo-rum et thoracis (MLLT) and the backfat of fattening gilts. A total of 40 animals were used, 20 in the experimental and 20 in the control group. The results indicate that gilts fed with the control feed mixture (C) showed a higher (P &lt; 0.05) content of intramuscular fat and backfat as compared to the experimental group (L) of gilts. A higher drip loss (P &lt; 0.001) was recorded in the L group as same as higher pH45 and pH24 values (P &lt; 0.01). The fatty acid profile analysis in the MLLT showed that the content of the MUFA (monounsaturated fatty acids) was lower (P &lt; 0.01) in the L group than in the C group of the animals and also showed a higher (P &lt; 0.01) content of the PUFA (poly-unsaturated fatty acids) in the L group. The content of the n-6 and n-3 PUFA was higher (P &lt; 0.001) in the L group. The ratio of the n-6/n-3 PUFA was significantly lower (P &lt; 0.001) in the L group. The PUFA/SFA (saturated fatty acids) ratio was more favourable in the L group of gilts (P &lt; 0.01). The results of the fatty acid profile analysis in the back-fat proved the higher (P &lt; 0.05) content of the UFA (unsaturated fatty acids) in the L group, while the content of the MUFA was lower (P &lt; 0.001) in the L group. The total content of the SFA was lower (P &lt; 0.05) in the L group. A higher content of the PUFA (P &lt; 0.001) in the backfat was recorded in the L group than in the C group and the content of the n-3 PUFA was higher (P &lt; 0.001) in the L group. The ratio of the n-6/n-3 PUFA was more favour-able (P &lt; 0.001) in the L group than in the C group. Also, the PUFA/SFA ratio was higher (P &lt; 0.001) in the L group.
