“…In this study, the 4:1 and 2:1 treatments showed a higher α-linolenic acid concentration nearly 4 fold in adipose tissue, whereas palmitoleic acid (C16:1c-9) concentration of SFA was reduced accordingly in comparison to pigs fed the control diet. In agreement, Leikus et al (2018) reported an improvement in the content of essential FA in adipose tissues of finishing pigs fed linseed. Additionally, Duran-Montgé et al (2009) indicated that the addition of linseed into diet showed a greater ratio of linolenic acid in adipose tissue of pigs.…”

Currently, there is a growing interest among consumers in selecting healthier meat with a greater proportion of essential fatty acids (FA). This experiment was conducted to evaluate the role of different ratios of dietary n-6:n-3 on growth performance, FA profile of longissimus dorsi (LD), relative gene expression of cytokines, meat quality, and blood parameters in finishing pigs. A total of 108 finishing pigs was randomly allotted to three treatments including a control (basal diet) and low ratios (4:1 and 2:1) of n-6:n-3. The 4:1 and 2:1 diets decreased the overall stearic acid in LD. There were reductions in the content of stearic acid, palmitoleic acid, total saturated acid, and n-6:n-3 ratio of LD in pigs fed 4:1 and 2:1 diet compared with the control diet. The 4:1 and 2:1 diets increased the concentration of α-Linolenic acid and polyunsaturated FA in the LD of pigs. Acetyl-CoA carboxylase enzyme gene was down-regulated in pigs fed 2:1 diet compared with finishing pigs fed the control or 4:1 diets. The relative expression of hormonesensitive lipase was increased in pigs fed 2:1 and 4:1 ratio diets. Lower total cholesterol of plasma was observed in finishing pigs fed 2:1 and 4:1 diets. The cooking loss ratio of meat was lower in pigs fed the 2:1 and 4:1 diets compared with the control diet. Pigs fed the 4:1 and 2:1 diets had greater final body weight. In conclusion, the 2:1 and 4:1 diets have the potential to increase the meat quality and growth performance of pigs.

“…However, in pig nutrition, which is based on feed mixtures with prevailing cereals, n-6 PUFA groups outweigh more favourable n-3 PUFA. To improve the n-6:n-3 fatty acids ratio, it is necessary to supply feed components rich in n-3 PUFA group (Wood et al, 2008;Leikus et al, 2018).…”

The objectives of this investigation were to examine the impact of the dietary inclusion of rapeseed and soybean oil and the length of their feeding before slaughter on growth performance, quantitative and qualitative carcass traits, and fatty acid composition in longissimus lumborum muscle (LLM) of pigs. The experiment was conducted with 72 pigs (36 barrows and 36 gilts), divided into six oil-containing diet groups and one control group. Diets of the experimental groups were supplemented with 4% rapeseed (ROD) or soybean (SOD) oil for six, four, and two weeks before slaughter. Diet of the control group had no oil supplement. Animals were fed ad libitum and slaughtered at average body weight of 115.8 kg. The oil supplement and feeding duration had a significant effect on fatty acid composition in intramuscular fat of LLM. The diet with both rapeseed and soybean oil significantly increased the content of linoleic acid and α-linolenic acid (ALA) in intramuscular fat. Both types of oil significantly increased total PUFA, n-3 PUFA, and the PUFA:SFA ratio. The significant decrease of n-6:n-3 PUFA ratio was observed in groups fed rapeseed oil for four and six weeks. Dietary addition of oils did not have any significant effect on average daily gain, carcass traits, and physical characteristics of LLM of pigs. However, daily feed intake and feed conversion ratio were reduced in the groups with soybean oil supplement. The results show that rapeseed oil supplementation (two weeks before slaughter) has positive effect on n-6:n-3 PUFA ratio and increase of ALA without negative effect on meat and fat quality.

“…Also, other studies proved that utilisation of flax in various forms and levels improves the fatty acid profile of the pork. For example, Bee et al (2008) used 3% of extruded linseed, Kralik et al (2010) used 2% of linseed oil, Okrouhla et al (2013) used linseed (150 g/kg) and Leikus et al (2018) used 25 g of linseed scrap per kg. These studies confirmed the increased n-3 PUFA, the overall improvement of the PUFA/SFA and the n-3/n-6 PUFA ratio in the intramuscular fat.…”

“…The analyses of the vegetable oils in terms of the fatty acid composition imply that certain varieties of flax (Linum usitatissimum L.) show a beneficial fatty acid composition, mainly a high content of the n-3 polyunsaturated fatty acids (PUFA) and particularly the alpha-linolenic acid, which is a precursor for other fatty acids of the n-6 and n-3 series (Beckova and Vaclavkova 2010;Jasinska and Kurek 2017). The works of Brodowska et al (2018) and Leikus et al (2018) suggest that a diet supplemen-Supported by the project of MENDELU internal grant agency, Faculty of Agriculture (No. TP 7/2017) and by the Ministry of Agriculture of the Czech Republic, institutional support No.…”

The study was designed to evaluate the effect of diet supplementation with linseed on the carcass characteristics, meat quality and oxidative stability as well as the composition of the fatty acids in M. longissimus lumborum 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 < 0.05) content of intramuscular fat and backfat as compared to the experimental group (L) of gilts. A higher drip loss (P < 0.001) was recorded in the L group as same as higher pH 45 and pH 24 values (P < 0.01). The fatty acid profile analysis in the MLLT showed that the content of the MUFA (monounsaturated fatty acids) was lower (P < 0.01) in the L group than in the C group of the animals and also showed a higher (P < 0.01) content of the PUFA (polyunsaturated fatty acids) in the L group. The content of the n-6 and n-3 PUFA was higher (P < 0.001) in the L group. The ratio of the n-6/n-3 PUFA was significantly lower (P < 0.001) in the L group. The PUFA/SFA (saturated fatty acids) ratio was more favourable in the L group of gilts (P < 0.01). The results of the fatty acid profile analysis in the backfat proved the higher (P < 0.05) content of the UFA (unsaturated fatty acids) in the L group, while the content of the MUFA was lower (P < 0.001) in the L group. The total content of the SFA was lower (P < 0.05) in the L group. A higher content of the PUFA (P < 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 < 0.001) in the L group. The ratio of the n-6/n-3 PUFA was more favourable (P < 0.001) in the L group than in the C group. Also, the PUFA/SFA ratio was higher (P < 0.001) in the L group.
