영어 초록

This study was conducted to test the effect different forages and feeding rates on generation of main greenhouse gases like carbon dioxide and methane in Hanwoo cows. Feeds were given twice per day at 09:00 and 17:00. Greenhouse gases were measured during 12 hours using Mamos-300 from 09:00 to 21:00. The results indicated that the generation of greenhouse gases under different forage categories and feeding rate were significantly different (p<0.05). Whole greenhouse gas tended to decrease in the high concentrate diets. The high timothy supplement ation group showed less amounts of carbon dioxide generation comparing with others group while high silage supplementation resulted more methane generation comparing with other treatments. On the afternoon test, carbon dioxide generation was significantly lower different (p<0.05) in timothy treatment comparing with others.
