## 3 Results and Discussion
[11] determined that the percentage of stearic acid in fallow deer meat significantly differed between wild (17%) and farmed animals (25%) and their observations of stearic acid percentage are similar to our presented results. \begin{table}

Practically all organisms need _n_-3 PUFAs for growth, development, and survival [45]. DHA is essential for the growth and operation of the brain and eyes. EPA and DHA have a variety of physiological activities that are connected to various health and clinical advantages, especially in relation to cardiovascular disease, cancer, inflammation, and neurocognitive function [46]. Most often, a person receives them in the diet by consuming fish (herrings, salmon, mackerels) and other marine products or by their use in the administration of medicinal formulations or dietary supplements [47]. Since the consumption of _n_-3 PUFA in human diets is low, the consumption of fallow deer meat could help to make up for this deficit. Desaturation, chain elongation, and peroxisomal beta-oxidation, which are all mediated by the enzymes 8-6 and 8-5 desaturase, chain elongation enzymes (elongases), and oxidase, can also be used to convert ALA to DHA and produce EPA and DHA. However, only a very small percentage of ALA in humans is converted to DHA. DHA is also referred to as a conditionally necessary fatty acid since vegetarians convert DHA at a rate of 3-8%, whereas omnivores convert it at a rate of just 1-3% [48]. In our experiment, the proportion of ALA in fallow deer meat was several times higher than in wild boar meat and pig meat. The similarity of the fatty acid composition in wild boar and pig meat can be explained by their species' similarity. To differentiate between domestic and wild pig muscle tissues in meals requires a distinction at the subspecies level which is more difficult.
