Comparative characteristics of fatty acid composition of bacon of breeds of pigs reared in the republic

Abstract

The studies generally helped to determine that on the total number of NLC Yorkshire, Belarusian large white and Duroc bbreeds prevailed - 45,25-46,98 %, indicating a more rigid structure and calorie content in fat. In samples of Landrace breeds, Belarusian meat and Black-motley breed in contrast dominated MUFA (45,20-49,48 %), they are less harmful to health than NLC, and have a positive effect on lipid metabolism, but more rapidly undergo oxidation. It was determined that the highest content of polyunsaturated fatty acids was peculiar of Yorkshire and Landrace animal breeds. They significantly surpassed all other breeds by 1.03-3.44 pp (P ≤ 0,001). Among Belarusian breeds the highest content of PUFA (10,02 %) was determined with animals of Belarusian black-motley breed. The lowest PUFA content was determined with animals of Duroc breed - 8,38 %.
