면양에 의한 야건초의 가소화성분 검정 = Digestion Trial for determination of the Digestible Nutrient Content of wild grass hay with Sheep

다국어 초록 (Multilingual Abstract)

The purpose of this experiment is to determine the digestible nutrient content of the native grass hay which was produced around the collge livestock farm. The grass was cut early in July 1959, and this sun-cured hay was very good in quality. The hay, consisted 70% of Digitaria Ciliaria Pers, 2% legume plants and others was chopped at about 5㎝ in length and stored in the wooden box to prevent the rat attack. The animals used were two heads of male sheep which were produced at Dai Kwal Yung livestock Experiment Station. The sheeps ware drenched twice at 10 days interval in order to remove the internal parasites and they were confined in the sound pen. The recommended amounts of hay was measured carefully and fed to the sheep twice a day. No other feeds were allowed except water. All the feces excreted by the sheep was collected twice a day by the water prove feces collecting bag and aged for analysis. The analysis of hay and feces have been done at college chemistry laboratory. The Summary of this experiment axe as follows: (1) The Chemical composition of the native brass hay is similar to those of Japanese native grass hay produced in Kwan To district, Japan. When comparing with the native grass hay of United States of America, this hay contains much more crude protein and carbohydrate. (2) The digestion coefficient of this experimental hay was generally high particularly the crude fat and crude fiber were still higher. This may be due to the early cutting of the grass to the quality of the hay and also to the animal itself. (3) The total digestive nutrients of this hay was about same as the pasture hay of United States of America and the Kikuyu grass hay of central and South America.
