Abstract

This study was conducted to investigate the effect of pasture grazing and barn feeding system on the growth performance, weight gain and velvet antler productivity in Elk. Twelve 5-year-old elk stags about 273 kg were stratified by weight and randomly assigned by feeding system (a pasture grazing and a barn feeding, n=6). The average feed intake were not signigicant difference between two groups. Average daily gain for grazing and barn feeding group was 0.25 g and 0.29 g respectively, showing no significant difference. Velvet antler yield for grazing and barn feeding group was 7,700 g and 6, 960 g respectively, with no significant difference. In conclusion grazing group was better than barn feeding group in feed intake, body weight gain and velvet antler productivity. However, there were no statistical significant difference between the two group. These results may serve as the basis for further study of deer feeding system in Korea and further study needed to examine the grazing intensity and economic efficiency.

본 연구는 엘크 사슴의 사육방식에 따른 사료섭취량, 체중 변화 및 녹용생산성에 미치는 영향을 확인하기 위하여 실시하였다. 엘크 사슴 12두를 공시하여 사사사육과 방목사육 형태로 사육하였으며, 처리구 간에 섭취량은 유사하게 나타났다. 일당증체량과 녹용생산성의 경우 방목사육 형태가 높게 나타났는데, 일당증체량은 방목사육 시 약 39% 높은 경향을 보였는데 이는 발육 개선효과가 있을 것으로 생각된다. 녹용 생산성 역시 방목사육 시에 약 19% 높은 경향을 보였다. 그러나 녹용 생산성의 경우 개체 간 편차가 심하여 통계적 유의성은 인정되지 않았다. 본 시험에서 방목사육 시에 일당증체량과 녹용 생산성이 높게 나타난 것은 방목에 따른 조사료원의 영양적 성분이 높기 때문으로 생각된다. 이러한 결과는 사슴 방목의 효과에 대한 기초자료로서 충분이 활용될 수 있을 것이며, 앞으로 계절과 방목지의 초종에 따른 녹용의 생산성과 안정성에 대한 추가적인 연구가 수행되어야 할 것으로 생각된다.
