초록
본 연구는 봄철 glutathione 급여가 엘크 사슴의 사료섭취량, 체중변화, 녹용생산량 및 경제성에 미치는 영향을 구명하기 위하여 실시하였다. 엘크 2세 수컷 14두를 공시하여 각각7두씩 대조구와 glutathione 급여구로 나누어 농후사료는 녹용성장기동안 체중의 1.5%(3.1 kg)를 급여하였고 조사료는 목건초를 자유채식 시켰다. glutathione은 체중 kg당 6 mg을 급여하였다. 그 결과는 다음과 같다. 엘크 2세의 녹용성장기 증체량은 대조구와 glutathione 급여구가 각각 234.1±17 및247.6±22 kg으로 glutathione 급여구가 유의적으로 높은 경향을 보였다 (p<0.05). 1일 DM섭취량은 대조구와 glutathione 급여구가 각각 5.34±0.70 및 5.64±0.71 kg를 섭취하여glutathione 급여구가 대조구보다 평균 298 g더 섭취하였다. 녹용생산량은 대조구와 glutathione 급여구가 각각4,229±720 g 및 4,653±960 g로 glutathione 급여구가 10%많았으나 개체차로 인하여 처리 간에 유의성은 인정 되지않았다. 경제성분석에서 녹용성장기 glutathione 급여가 대조구보다 소득 지수는 8% 높았다. 이상의 결과를 종합하면 엘크 사슴에 대한 glutathione 투여는 일당증체량 및 녹용생산량을 개선시키는 효과가 있어서 경제성이 있다고 하겠다.
Abstract
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.
