摘要

本研究的目的是对不同基因型(曼加利察和长白猪)猪的化学成分和脂肪酸组成以及结缔组织蛋白进行比较分析。两种基因型猪均饲喂相同的标准成分和质量饲料。育肥期结束时,两种基因型共屠宰24头猪。根据化学成分分析,两种基因型的蛋白质含量相似。各基因型长白猪水分和灰分含量差异显著(P0.05)。试验品种间PUFA含量、n-3和n-6脂肪酸含量差异无统计学意义,因此n-6/n-3 PUFA比值差异无统计学意义。Mangalitsa品种的不饱和脂肪酸(即MUFA和PUFA的总和)和饱和脂肪酸的比例显著高于长白品种(1.86比1.4),在MUFA/SFA (Mangalitsa品种1.51比长白品种1.08)和MUFA/PUFA(4.35比3.38)的关系上也观察到相同的结果。

Some parameters of nutritional quality of meat obtained from Mangalitsa and Landrace pig breeds
The aim of this study was to provide a comparative analysis of chemical and fatty acid composition, as well as of the connective tissue proteins in pigs of different genotypes, Mangalitsa and Landrace. Both pig genotypes were fed with the same feed of standard composition and quality. At the end of the fattening period, in total 24 pigs of both genotypes were slaughtered. Based on the analysis of the chemical composition we came to the conclusion that the protein content in both genotypes was similar. Moisture and ash content in the Landrace pig genotype differed significantly (P<0.01) compared with genotype of pigs Mangalitsa breed. Statistically significant differences (P<0.01) were established in the fat content, which was 7.95 g/100g, in pigs of Mangalitsa breed and 1.59 g/100g in the Landrace pigs breed. Content of hydroxyproline, non-proteinogenic amino acids, in meat of Landrace was significantly higher (P<0.01) compared to the content in the Mangalitsa breed. The same tendency was observed with regard to the connective tissue protein content as well as with the relative connective tissue protein content. The fatty acid composition of the meat indicated that the most common saturated fatty acid (SFA) in both tested breeds was palmitic fatty acid (C16), whose content was significantly higher in Landrace (P<0.01) compared with its content in Mangalitsa breed. In addition, the share of stearic acid (C18) was significantly higher (P<0.01) in Landrace compared to Mangalitsa pig breed, what significantly contributed to the increase of the SFA share in Landrace compared to Mangalitsa breed. The most common monounsaturated fatty acid in both pig breeds was the oleic fatty acid (C18:1), whose share was significantly higher in Mangalitsa compared to the Landrace breed (P<0.01). Out of the polyunsaturated fatty acids (PUFA), linoleic fatty acid (C18:2) was the most predominant in both pig breeds, with no statistically significant differences (P>0.05). The content of PUFA was not statistically significantly different between the tested breeds, as well as the content of n-3 and n-6 fatty acids, which caused no statistically significant differences in the n-6/n-3 PUFA ratio. Ratio of the unsaturated fatty acids, i.e., of the sum of MUFA and PUFA, and of the saturated fatty acids was significantly higher in Mangalitsa compared to Landrace breed (1.86 versus 1.4), and the same was observed when it comes to the relationship MUFA/SFA (1.51 in Mangalitsa versus 1.08 in Landrace breed) and MUFA/PUFA (4.35 versus 3.38).
