The objective of this study was to investigate the effect of carcass weight on chemical characteristics and fatty acid composition of m. longissimus dorsi and m. semimembranosus of European wild boar (Sus scrofa scrofa) meat. The research was carried out on 50 wild boars shot during four battues at hunting reserves in the central part of Poland. The carcasses were divided into three groups: ≤30 kg (G1), 31–45 kg (G2), and >45 kg (G3). The protein concentration increased with carcass weight (P ≤ 0.01). The concentration of saturated fatty acids was influenced by carcass weight and was higher when weight increased. A significantly higher level of monounsaturated fatty acids (MUFA) was found in the carcasses of wild boars from G3 compared with G1 group (P ≤ 0.01). The content of C18:2n-6 was significantly lower in the lightest carcasses compared with the heaviest (P ≤ 0.05). Statistical analysis confirmed that carcasses weight significantly affected polyunsaturated fatty acids (PUFA) n-3 content. The lightest carcasses contained a significantly higher concentration of PUFA n-3 (P ≤ 0.01). In addition, in G3, the amount of C22:5n-3 was two-fold lower (P ≤ 0.01) than in G1. The research has shown that the meat quality was affected by the carcass weight, resulting better parameters in the lighter than in the heavier carcasses. Therefore, most of the culled wild boars should be squeakers and young boars after the first year of life.

The aim of this study was to provide information on the fatty acid profile of different adipose depots - subcutaneous (upper and inner backfat layers) and intramuscular (m. Longissimus dorsi) in East Balkan pigs. The animals were reared in free-range conditions and slaughtered at an average live weight of 107?1.65kg. The results of the study showed that the various adipose tissues in pigs have different lipid metabolism and hence differ in their fatty acid composition. Intramuscular fat had significantly higher content of the saturated C16:0 and C18:0 (P<0.001), as well as the C16:1 (P<0.001) than the subcutaneous fat. In regards to the content of the polyunsaturated fatty acids, the latter displayed considerably higher content of both C18:2 and C18:3 (P<0.001) in comparison to the intramuscular fat in m. Longissimus dorsi. The differences between the subcutaneous and intramuscular adipose tissue in the individual fatty acids determined the similar trend of change in the total content of saturated and polyunsaturated fatty acids. Significant differences between the backfat layers were detected for C16:1, C18:0 and C18:3 (P<0.001). Stearic acid (C18:0) displayed higher content of the inner, while both C16:1 and C18:3 had higher proportion in the outer backfat layer in the East Balkan pigs. Except for C20:2, the long chain polyunsaturated n-6 and n-3 fatty acids had significantly higher proportions in the intramuscular fat, however no differences were determined between the two backfat layers.

Abstract. This study was undertaken to characterize the fatty acid profile and sensory properties of longissimus dorsi (LD) muscle of Boer kids as affected by sex (17 male, 15 female) and slaughter weight (pre-weaned 20 kg, post-weaned 30 kg). Regarding sex differences, higher percentage amounts of lauric, myristic, pentadecanoic, linolenic and docosapentaenoic acids were found in LD muscle of male compared to female kids, whereas greater amounts of oleic acid were detected in LD muscle of female kids. Also, LD of male kids contained higher percentage amounts of saturated (SFA), polyunsaturated (PUFA) and n-3 polyunsaturated fatty acids (n-3 PUFA) while higher amounts of monounsaturated fatty acids (MUFA) were detected in LD of female kids. Regarding slaughter weight, percentage amounts of lauric, myristic, margaric, pentadecanoic, linolenic, linoleic, arachidonic and docosapentaenoic acids significantly decreased with age (P≤0.001), while percentage amounts of heptadecenoic and oleic acids significantly increased (P≤0.001). LD muscle from lighter kids contained higher percentage amounts of SFA and PUFA, while heavier kids had higher percentage amounts of MUFA and n-3/n-6 fatty acid ratio. Except meat colour, sensory traits (marbling, off-odour, flavour, juiciness and tenderness) were neither significantly affected by sex nor slaughter age.

The aim of the study was to determine the concentration of selenium in the meat of wild boars from three selected regions of Poland. Selenium concentration was analysed in relation to the region (Masuria, Pomerania and Greater Poland) and in relation to the carcass weight and sex of the animals. The average content of selenium in the material was 0.093 μg/g. The highest mean concentration was observed in the meat samples from Greater Poland (0.099 μg/g) and in the muscle tissue of females (0.098 μg/g). The most valuable source of selenium was the meat of animals with carcass weight ranging from 21 to 40 kg (0.101μg/g). A 100 g portion of wild boar meat meets about 20% of the daily requirement for selenium for adults and 30% for children.

Abstract. Nowadays, meat and meat products from indigenous pig breeds are desired by consumers for their high sensory quality. For that reason, the trend to use indigenous pig breeds for production of these products has widened. The aim of this study was to compare physical and chemical parameters of Musculus longissimus dorsi (MLD) as well as content of cholesterol and fatty acid profiles among Mangalitsa, the crossbreed Mangalitsa × Duroc, and pig meat breed Slovak Large White with Polish indigenous breeds Pulawska and Zlotnicka spotted. In the study, 48 pigs were used. The pigs were divided into 5 groups of different genotypes: Mangalitsa breed (n = 9), the crossbreed Mangalitsa × Duroc (n = 9), Slovak Large White – SLW (n = 10), Zlotnicka spotted (n = 10) and Pulawska (n = 10). The pigs were reared under intensive conditions, and they were fed by an ad libitum system with complete feed mixtures. The fattening period lasted from 30 to 100 kg of live weight. The SLW had the highest average daily gain with the lowest feed intake compared to Mangalitsa, the crossbreed Ma × Du and Polish indigenous breeds (P < 0.001). SLW had the highest meat content in the carcass while Mangalitsa had the lowest (P < 0.001). Mangalitsa and their crossbreed Ma × Du had the highest fat content in the carcass, but the SLW and Polish indigenous pig breeds had the lowest fat content in the carcass (P < 0.001). As regards the physical properties of MLD, the Polish indigenous pig breeds achieved the highest values of pH45 min post mortem, the lowest drip loss values, the lowest colour values of CIE L* and the highest values of CIE b* compared to other genotypes in the experiment (P < 0.001). However the meat of crossbreed Ma × Du had pale, soft and exudative (PSE)-like conditions due to the low pH45 min post mortem, the high values of drip loss and CIE L*. The crossbreed Ma × Du and Polish indigenous pig breeds had the highest content of intramuscular fat in MLD compared to Mangalitsa and SLW (P < 0.001). The cholesterol content in MLD was the highest in Polish pig breeds and the lowest in SLW (P < 0.001). Regarding the fatty acid content in the meat, intramuscular fat (IMF) from Zlotnicka spotted was significantly the most polyunsaturated with the highest percentages of C18:2n-6, C20:5n-3 and C22:6n-3, and it had the lowest percentages of monounsaturated fatty acids (MUFAs) as well as contents of C18:1cis-9 and C18:1trans-11 compared to other genotypes (P < 0.001). IMF from Slovak Large White was the most saturated and monounsaturated with the highest content of C18:1cis-9, and it has the lowest percentages of polyunsaturated fatty acids (PUFAs) in IMF compared to genotypes in the study (P < 0.001). From the results, it follows that the Polish indigenous pig breeds are more suitable for the breeding and production of special meat products due to acceptable fattening and carcass parameters as well as the meat quality. As regards fatty acid composition of meat, the direct influence between fatty acid composition in diet and in Musculus longissimus dorsi was not determined. However, the genotypes have a significant impact on fatty acid profiles in MLD.

Abstract Interest in meat quality and its fatty acid composition stems mainly from the need to find ways to produce healthier meat. In Puerto Rico, no documented information is available on the nutritional profile in the meat of lambs raised under local conditions (crossbred animals raised in heat stress and grazing naturalized pastures, NP). The quality of meat and fatty acid composition was evaluated, of 12 lambs grazed NP &gt; 8h, tropical grass hay and water ad libitum, 150g of concentrate (12% CP), and mineral blocks. Six animals were slaughtered at two live weight of 22 (SW1) or 35 (SW2) kg to determine the meat quality given by pH, color, nutrient content, and the fatty acid composition in the Longissimus dorsi muscle. The data was analyzed using a completely randomized design with two treatments and six repetitions. SW1 and SW2 had similar pH (5.57 vs. 5.73), but lambs at SW1 displayed lower (P &lt; 0.01) a* value than those slaughtered at SW2 (11.18 vs 13.57), but L* (38.91 vs 37.56) and b* (10.72 vs 10.67) values were similar. On both slaughter weight moisture (75.63 vs 74.51), ash (4.10 vs 3.34), crude protein (24.36 vs 25.12), and crude fat (2.30 vs 2.01) percentage of the meat was similar. The total lipid content (0.953 vs 2.25), saturated fatty acids (34.68 vs 42.98), and monounsaturated fatty acid (28.36 vs 37.28) of lambs at SW1 was lower than those at SW2, but n-6 and n-3 polyunsaturated fatty acids (18.74 vs 8.57and 6.61 vs 2.88, respectively) were higher (P &lt; 0.05). The n-6/n-3 ratio was similar for both SW groups (2.84 vs 2.96). Differences in individual fatty acid content due to the slaughter weight were observed. In conclusion, the meat quality and the fatty acid composition of the Longissimus dorsi were affected by slaughter weight of lambs grazing naturalized pastures.

The effects of feeding different levels of whole linseed on fatty acid (FA) composition of muscles and adipose tissues of goat were investigated. Twenty-four Crossed Boer bucks were assigned randomly into three treatment diets: L0, L10, or L20, containing 0%, 10%, or 20% whole linseed, respectively. The goats were slaughtered after 110 days of feeding. Samples from thelongissimus dorsi,supraspinatus,semitendinosus, and subcutaneous fat (SF) and perirenal fat (PF) were taken for FA analyses. In muscles, the average increments inα-linolenic (ALA) and total n-3 PUFA were 6.48 and 3.4, and 11.48 and 4.78 for L10 and L20, respectively. In the adipose tissues, the increments in ALA and total n-3 PUFA were 3.07- and 6.92-fold and 3.00- and 7.54-fold in SF and PF for L10 and L20, respectively. The n-6 : n-3 ratio of the muscles was decreased from up to 8.86 in L0 to 2 or less in L10 and L20. The PUFA : SFA ratio was increased in all the tissues of L20 compared to L0. It is concluded that both inclusion levels (10% and 20%) of whole linseed in goat diets resulted in producing meat highly enriched with n-3 PUFA with desirable n-6 : n-3 ratio.

The aim of the present study was to evaluate the influence of castration (surgical and immunological) and sex on lipid hydrolysis, oxidation and antioxidant capacity in selected muscles/cuts of pigs. Nine muscles/cuts from four groups of pigs (surgically castrated, entire males, immunocastrated and sow) were analysed. Free fatty acids (FFA) were analysed using standard methods according to CSN EN ISO 660. Thiobarbituric reactive substances (TBARS) were determined as malondialdehyde (MDA) equivalents and antioxidant capacity was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method . The highest content of FFA was observed in sows, detected to be significantly (P < 0.001) higher than in entire males. The highest content of TBARS was found in entire males; the content was significantly (P < 0.05) higher than in sows. Generally, the highest values of DPPH inhibition were detected in samples of surgically castrated pigs whereas the lowest values were observed in samples of entire males. Antioxidant capacity in musculus longissimus dorsi and backfat of surgically castrated pigs was significantly (P < 0.05) higher than in other evaluated groups of pigs. The study confirmed the differences in FFA and TBARS formation between analysed groups of pigs, probably due to differences in the fatty acid composition. The results of our study indicate that methods of castration have an effect on the antioxidant capacity of pork. These findings are of value to the meat industry.

Effect Of Age

The aim of the study was to analyse the fatty acid profile of wild boar (Sus scrofa) meat. The samples were obtained from the mountain Tríbeč (southwest part of the Slovak Republic). A total of 36 samples in 3 age categories of meat were analysed. The effect of age on the intramuscular (IMF) fat content was analysed. The highest (P < 0.05) IMF content was found in the samples from the youngest animals (18.07%), the lowest (P < 0.05) in the sub-adult animals. Significant (P < 0.05) differences were found in palmitic acid (C16:0). Significant decrease of heptadecanoic acid (C17:0) as an effect of age was analysed in the samples. Of the important fatty acids, the most abundant in all age categories of wild boar were oleic (C18:1 cis 9), palmitic (C16:0), and linolelaidic acid (C18:2 cis n6). Differences in the content of mentioned acids were significant (P < 0.05). In α-linolenic and γ-linoleic acids, non-significant (P > 0.05) differences were detected. Significant differences (P < 0.05) between age categories were found in cis-11-eicosenoic (C20:1 n9) and cis-11,14-eicosadienoic acids (C20:2 n6). Significant differences (P < 0.05) were found in PUFA (polyunsaturated fatty acids), MUFA (monounsaturated fatty acids), and SFA (saturated fatty acids) concentrations. The highest PUFA content was typical for the samples from the oldest animals, MUFA from the sub-adults, and SFA from the youngest wild boar. More significant results were observed in the normalized data with the factor component scores. The wild boar fatty acid profile is significantly affected by age.
