The recommendation for the PUFA/SFA ratio is >0.40, and for the n-6/n-3 ratio it is <4.0 [51]. The tested fat samples were characterized by the beneficial PUFA/SFA ratio, but did not meet the criterion for n-6/n-3 ratio. In the diet the n-6/n-3 ratio lower than 4.0 proves the proper composition of fatty acids in the context of reducing the risk of cardiovascular diseases [12; 28]. Based on the obtained results, it can be stated that boar fat was the nearest to this recommendation. A healthy animal product can be characterized by low atherogenic index (AI) and thrombogenic index (TI) and high hypocholesterolem/hypercholesterol (h/H) index. The AI and TI values for tested fat samples were <1, as recommended, and the h/H ratio was at a favorable value of >2.5 for badger and goose fat. The consumption of products with a lower AI is associated with reduction of human plasma total cholesterol and low-density cholesterol (LDL) [52]. In turn, the consumption of product with a lower TI and higher h/H ratio can be beneficial in the prevention of cardiovascular heart diseases [50]. Comparing values of the peroxididizability index (PI), which is used to assess the stability of PUFA and susceptibility to oxidation [31], the lower value was found for badger fat. This indicates a lower potential for the peroxidation of this fat and it is associated with lower PUFA content. In the present study, results obtained allow us to state that the wild goose fat was characterized by the lowest stability (the highest PUFA content). The total PI for a particular lipid can reach from 2 for coconut oil, 5 for tallow (low potential for peroxidation) or over 10 for palm oil, olive or lard to higher than 100 for flaxseed oil or algae oil (high potential for peroxidation) [53]. Taking into account the PI values, the fats from the tested samples were characterized by average stability. However the results of PDSC measurements allowed us to conclude that boar fat was the most oxidatively stable, and goose fat was the least oxidatively stable of the analyzed fats. Comparing FA profiles and nutritional and healthy quality of tested samples with other sources of animal fat such as lard or tallow [53], it should be emphasized that the fat of wild animals, despite a similar FAs composition, comprises more other long chain PUFA. As a result fats from wild animals may be valuable fat source in diet. This study had limitations. In the present study we did not analyze the effect of sex, age as well as seasonal variations on quality and fatty acids composition of studied samples. However, as reported by [PERSON] et al. [35], weight or sex had no effect on the FA composition and lipid quality indexes either in the intramuscular or in the subcutaneous fat from wild boar. The same authors highlighted that significantly lower AI and TI indices and higher, more favorable h/H ratio were observed in the intramuscular fat of wild boar hunted in January compared with June [54]. Quality and FAs profile of game wild meat largely depend upon factors such as habitat conditions, including access to a different food. In addition, the quality of meat, as well as the FA profile in adipose tissue, is influenced by regional differences, living conditions--agricultural land (fields, meadows, fruit orchards), natural habitats (forests, pastures, wastelands), as well as the season of the year (in autumn greater fat deposition before in winter, both in the form of subcutaneous layers and tallow).
