영어 초록
We investigated the effect of glutathione supplementation on body weight gain, feed intake, velvet antler yield and economic analysis in elk bulls. A total 14, 2-year old male elks were divided into 2 groups with control or glutathione treatment. Elks were fed concentrate feed at the level of 1.5% relative to body weight (3.1 kg). and allowed to consumed hay as roughage ad libitum. Glutathione was supplemented at the level of 6 mg/kg. Average daily gains (ADG) for 2-years old elks were 234.1± 7 and 247.6±22 kg in control and glutathione fed groups, respectively. Treated group had higher ADG than control (p<0.05). Individual daily DM intakes were 5.34±0.70 and 5.64±0.71 kg in control and glutathione supplemented groups, respectively. Glutathione-fed group showed an additional intake of 298 g on an average. Production of velvet antlers for elk yearlings was 4,229±720 g and 4,653±960 g in control and glutathione supplemented groups respectively. Analysis of economics efficiency revealed 8% higher revenue index in glutathione supplemented groups. In conclusion, glutathione supplementation showed increase of DM intake and ADG in elk bulls, and could also increase velvet antler production.
