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).
