Abstract
In order to develop feed source from shrubby area of mountain for dairy cow, some shrub and grass were harvestied by stage of maturity and analyzed the chemical composition of herbage, and fed to milking cow to know the effect on the body weight and milk production. And the results were summarized as follow. 1. The dry matter content of green herbage was ranged average 25~50% and Smilax china and Cocculus thunbergii were the lowerest as 26.25% and 26.36% respectively and Quercus serrata was the highest as 47.19% of the species. 2. The average protein content of herbage was widely ranged from about 5% to 20%. And Pueraria thunbergiana and Albizzia julibrissin were higher as nearly 20% and Miscanthus sinesis and Arundinella hirta were lower as nearly 5~7%. 3. The average crude fiber content of most species was rarged 20~30%. And Corylus heterophylla and Smilax china were lower as about 20% and Miscanthus sinensis and Arundinella hirta were higher as nearly 37%. 4. The crude protein content of most species was decreased and the fiber content was increased by abvanced the stage of maturity. And also moisture content of green herbage was decreased by seasonal changed. 5. When air dry herbage of 5 kg per head/day was substituted for rice straw, the weight of cows and milk yield and solid not fat content were Slightly increased.
젖소등 초식 가축의 사료 자원개발을 위하여 국내 산지에 다량으로 자생되고 있는 관목류 및 초류중 비교적 가축 사료로써 활용 가치가 있어 보이는 수종의 관목초류를 택하여 시기별로 사료성분을 분석하고 젖소에 대한 일부 급여 시험을 실시하여 다음과 같은 결론을 얻었다. 1. 관목초류의 건물 함량은 평균 25~45%의 범위를 나타내고 있으며 이중 청미례와 댕댕이덩쿨이 각각 26.25%와 26.36%로 가장 낮았고 졸참나무가 47.19%로 가장 높게 나타났다. 2. 조단백질 함량은 건물량 기준으로 대부분 10% 이상으로 나타났고 이중 칙과 자귀나무가 평균 20% 정도로 가장 높게 나타났으며 억새와 새는 평균 10% 미만으로 낮게 나타났다. 3. 조섬유 함량은 평균 20~30% 뱅위로 타나났으며 개암나무와 청미례가 20% 정도로 가장 낮았고 억새와 새는 37% 이상으로 높게 나타났다. 4. 대부분 관옥 사초류는 시기가 경과함에 따라 조단백질 함량이 줄어 들고, 조섬유 함량이 증가되는 경향을 보였으며, 또한 건물량이 증가되였다. 5. 관목초본류를 볏짚 대용으로 1일 두당 5kg을 급여한 결과 체중과 유량 및 무지고형분 함량이 약간 증가되는 경향을 보였다.
