Abstract

<p>Wild female Yeso sika deer (Cervus nippon yesoensis), captured around Lake Akan in Hokkaido during winter, were fed for short time. During the short time feeding, fawns were born. After 15-23 weeks, 5 fawns were slaughtered and carcass and cut meat were collected in the present study. Body weight, feed intake, carcass weight, total meat weight and cut meat weight were measured. Chemical compositions, mineral contents of loin were analyzed. Birth weight and daily gain were 3.8 - 5.8 kg and 83.6 - 179.1 g, respectively. The daily gain was heavier in the heavier fawn. The weight of carcass and total meat were 8.5 - 15.5 kg and 5.0 - 10.9 kg, respectively. The yield of carcass and total meat were 41.9 - 51.1 % and 27.1 - 34.6 %, respectively. In the cut meats, round was the heaviest (3,222 g; 46.6 %), followed with shoulder (1,330 g; 19.4 %) and brisket (960 g; 13.5 %). Crude protein and crude fat content were 19.2 - 22.9 %FM and 0.8 - 3.2 %FM, respectively, and there were large individual differences. Moisture and crude ash content were 71.7 - 76.4 %FM and 1.1 - 1.4 %FM, respectively. Sodium, calcium and iron content in the meat had high variability. Cadmium, lead and molybdenum were not detected.</p>
