Evaluation of nutrition value of deer meat obtained in Latvia farms and wildlife

In last years diversity of species grown under organic farming system has expanded and consumption and assortiment of game meat products has significantly increased. Deer farms have come in view. Investigations about biochemical composition of game meat are few. The investigations were carried out in different regions of Latvia. The chemical analyses of 45 samples were done wild and farm deer and beef obtained in organic production sistem in Latvia. In the studied samples protein and amino acids, fat and faty acids were determined. Content of protein in samples of game meat was 19.61 - 23.6%. The sum of essential amino acids in game meet samples were determined from 21.7 - 42.6 mg 100 g(-1). Concluded that the content of saturated fatty acids was lower in the meat samples of wild deer 33.6%, while in the meat samples of farm deer and beef it was higher 41.2% and 40.3% respectively. Because of the relatively high polyunsaturated fatty acid content and low saturated fatty acid content, wild game meat is more beneficial for human health. From results of our investigation concluded that the content of saturated fatty acids in meat samples of wild deer (33.6%) was lower in comparison with meat samples of farm deer (41.2%). From results of investigation we can see that ratio of polyunsaturated fatty acids nn omega - 6 /omega - 3 in deer meat samples were 1,1 - 1,4 and beef - 4,8. It is evaluated that nutrition value of wild game meat is higher than beef from organic farming sistem.
