초록

본 연구는 사슴의 조사료 원으로 엘크사슴에 대한 청보리 사일리지 급여가 사슴의 사료섭취량, 체중변화 및 경제성에 미치는 영향을 구명하기 위하여 실시하였다. 엘크사슴 21두를 공시하여 건초구, 청보리 사일리지구 및 건초+청보리 사일리지구로 나누어 농후사료를 3.7 kg 정량급여 하고 조사료는 자유채식 시켰으며, 그 결과는 다음과 같다. 엘크사슴의 일당증체량은 건초구, 청보리 사일리지구 및 건초+청보리 사일리지구 혼합구가 각각 0.26, 0.36 및 0.44 kg으로 건초+청보리 혼합구가 가장 높았고, 엘크사슴의 청보리 사일리지 일일섭취량은 6.25~9.00 kg (풍건) 범위였으며, DM 섭취량은 건초구, 건초+청보리 사일리지 혼합구 및 청보리 사일리지 순으로 높은 경향을 보였다. 녹용 생산량은 건초구, 청보리 사일리지구 및 건초+청보리 사일리지구가 각각 8,037, 7,713 및 8,585 g으로 건초+청보리 사일리지 혼합구가 가장 많았다. 3개 처리구간 일당증체량, 녹용생산량 및 사료섭취량은 사슴의 개체차가 심하여 통계적으로 유의성은 인정되지 않았지만(p>0.05) 증체량 및 녹용산량은 증가하는 경향을 보였다. 경제성 분석에서는 건초+청보리 사일리지 혼합구가 건초 및 청보리 사일리지 단독급여구보다 소득지수가 29~43% 높게 나타났다. 이상의 결과를 종합적으로 고려할 때 사슴의 조사료 원으로 청보리 사일리지는 기호성에서 건초를 대체할 만큼의 섭취량을 가지므로 이용가능성이 있었으며, 조사료 원으로 연중 공급이 가능하고, 경제적인 측면에서도 건초보다 유리하여 농가에서 사슴의 조사료 원으로 사용이 가능할 것으로 사료된다. 또한 청보리 사일리지 급여 시에는 청보리 사일리지 단독 급여보다는 청보리와 건초를 각각 50%씩 혼합 급여하는 것이 일당증체량, 증체, 녹용생산량 및 경제성에서 가장 바람직한 것으로 사료된다.

This study was conducted to determine the effect of dietary whole-crop barley silage on the daily feed intake, daily weight gain, velvet antler yield and economic efficacy in elk during growth. A total of 21 elk (average BW 303 kg, 5 years old) were allotted randomly to three treatments. The three treatments were T1 (hay diet), T2 (whole-crop barley silage), and T3 (50% hay + 50% whole-crop barley silage). The average daily weight gain of T3 was higher than the others throughout the entire experimental period. The average daily feed intake of elk in decreasing order was as follows; T1>T3>T2. The velvet antler yield was higher in T3 group (8,585 g) compared with T1 (8,037 g) and T2 (7,713 g). However, there were no significant differences in the average daily feed intake, average daily weight gain, or velvet antler yield (p>0.05). In economic efficacy, T3 was gained about 29~43% more value than T1 or T2. In conclusion, the mixed feeding of 50% hay and 50% whole-crop barley silage was more effective than feeding hay of barley alone, in terms of average daily weight gain, velvet antler yield, and economic efficacy in elk.
