Some parameters of nutritional quality of meat obtained from Mangalitsa and Landrace pig breeds
Abstract
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 0.05). 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 vs. 1.4), and the same was observed when it comes to the relationship MUFA/SFA (1.51 in Mangalitsa vs. 1.08 in Landrace breed) and MUFA/PUFA (4.35 vs. 3.38).
