Deer farming is quite a new animal husbandry branch developed in Latvia from the year 1994. The aim and tasks of the investigation were to find out deer (Cervus elaphus) blood and meat biochemical indices, to evaluate the diet value by investigations of amino acids content and to compare it with beef of cross LB x HE (Latvian brown and Hereford). The biochemical analyses of deer and beef of cross LB x HE (m.longissimus lumborum) samples were carried out. Blood biochemical samples were detected by Hymalyser 2000-bicromatic photometr System. Amino acids content was detected by High pressure liquid chromatography (HPLC), and intramuscular fat - by Soxlet methods. Deer and beef blood biochemical parameters did not exceed physiological norms. The obtained results indicated that deer meat contained higher level of essential amino acids lysine by 6.3%, threonine by 11.0%, valine by 14.1%, methionine by 2.5%, isoleucine by 9.7%, leucine by 13.1%, phenylalanine by 10.7% than beef of LB x HE cross. Most of nonessential amino acids of deer meat had increased contents in comparison with beef. Intramuscular fat content in deer meat was by 0.4% less than in beef. It can be concluded from obtained results that deer meat is more dietetic than beef.
