Abstract

This experiment was conducted to investigate the effects of feeding TMR(Total Mixed Ration) with Sasa quelpaertensis Nakai of Jeju cross-bred horses on the body weight and blood composition. Fourteen herds of Jeju cross-bred horses older than 36 months were selected as experimental animals. The experiment was conducted by dividing the herds into seven herds for feeding TMR with 20% Sasa quelpaertensis Nakai(treatment) and another seven herds for feeding TMR without Sasa quelpaertensis Nakai(control) and water were fed ad libitum. In the 12th week, the MPV(mean platelet volume) was statistically significantly higher with Sasa TMR than with control (p<0.05). However, both MPV levels are within a normal range and there were no health problems. With regard to the levels of cholesterol, there was a statistically significant difference between the 33.8±5.9 mg/㎗ with individual management and 25.4±8.2 mg/㎗ with control group (p<0.05). But It are also within a normal range and there were no health problems. In conclusion, feeding TMR with 20% Sasa quelpaertensis Nakai of Jeju cross-bred horses could be utilized as a feeding method for horse.

본 연구에서는 제주 한라산 일대에서 자생하고 있는 제주조릿대의 말 사료 자원화 가능성을 검토하기 위하여 수행되었다. 제주조릿대의 사료적 가치를 평가하기 위해서 제주조릿대를 생초로 TMR에 첨가하여 한라마에게 급여한 후 한라마의 성장, 혈액 성상을 조사하였다. 사료 섭취량은 조릿대 첨가 TMR을 급여한 처리구가 대조구보다 높았지만 유의적인 차이를 보이지 않았으며 섭취에 따른 증체량도 차이를 보이지 않았다. 공시마의 혈액에 대한 일반 성분을 분석한 결과, 대조구에 비해 처리구의 MPV 수치가 유의적으로 낮았지만(p<0.05) 정상 수치 내에 있었고 다른 수치도 차이를 보이지 않았다. 콜레스테롤 등의 수치는 기존의 연구 결과와 다소 차이가 있게 나타나 제주조릿대를 급여한 말에서 콜레스테롤이 더 높아지는 경향을 보였고 특히 LDL이 유의적으로 높게 나타났지만(p<0.05) 정상 수준이었다. 이는 제주조릿대의 첨가비율이 콜레스테롤 수치에 영향을 미칠 만큼 많지 않았기 때문으로 사료된다. 면역 수치에서도 처리구에 따른 차이를 보이지 않았다. 결론적으로 제주조릿대 20% 첨가 TMR의 급여에 따른 일반 혈액성상(CBC, complete blood cell count) 및 화학 수치를 조사한 결과, 모든 수치가 정상 범위 안에 있었고, 콜레스테롤 관련 수치에서도 제주조릿대 미첨가 사료와 큰 차이를 보이지 않고 정상 범위 내에 있어 말용 TMR 생산 시 제주조릿대를 조사료의 대체 자원으로 활용 가능할 것으로 사료된다.
