달 ( Phragmites longivalvis Steudel ) 의 생산력과 소화율검정
김범태 ( Peom Tae Kim ) 한국축산학회 1976 한국축산학회지 Vol.18 No.1
This experiment was conducted to evaluate productivity and digestibility of the Phragmites longivalvis Steudel, The results obtained are summarized as follow: 1. The cutting was possible twice in spring and autumn through a year and the green yield of the two cutting lot was more generative harvest than other lots. 2. The hay percentage was lower at the early growing stage and increased as the stage of maturity progressed, the average hay percentage per year was about 41 percent. 3. The length of grass was about two meters and twenty centimeters to three meters and it was the tallest of Korean native grasses. 4. The crude protein content was generally higher as compared with native grass, the crude protein content decreased as the growing stage progressed toward maturity and the crude fiber content increased as the stage of maturity advanced. The stalks were not worth for feed that cuts once in a year on september 30. 5. The hay digestibility test on samples was collected from downstream area of Goum Kong on May 31, 1974. The digestibility and the amount of digestible nutrients was medium duality as compared with Korean native grass.
달뿌리풀 ( Phragmites prosturatus ) Silage 의 기호성과 사육에 관한 시험
김범태 ( Peom Tae Kim ) 한국축산학회 1976 한국축산학회지 Vol.18 No.1
This experiment was carried out to compare the palatability and feeding of the phargmites prosturatus silage with those of corn silage. The results obtained in this experiment were as follows; 1. Tire crude protein in the chemical composition of the phragmites profturatus silage way higher than the control lot and it was found good quality. 2. The organic acid of the Phragmites prosturatus silage and the PH was similar to control lot and the silage quality by KIRSCH method was good quality. 3. The palatability of phragmites pro. silage was similar to control lot and it was not significant. 4. The body weight of phragmites pro. silage was similar to control lot and it way not significant. It is concluded that the phragmites prosturatus silage could be utilized on equal feed as corn silage.
