Abstract

The present study investigated the effect of forage sources and their inclusion levels in diet on the rumen fermentation of Korea traditional goat. Timothy and alfalfa were used as forage sources. Forages were mixed with concentrate diet in different ratios. The ratios of forage to concentrate diets were varied to 1:9, 5:5 and 9:1. The rumen fluid of goat was gathered from slaughter house. Dry matter digestibility was decreased and methane production was increased as forage levels in diet was increased. When forage sources, timothy and alfalfa, were compared, groups with timothy showed greater methane production than the groups of alfalfa. Molar ratio of produced acetate and valerate were increased when forage level in diet was increased. In the case of propionate and butyrate, they were decreased as elevated forage levels in diet. The result of this study provided a basic information for rumen fermentation of Korean traditional goat and these information could be applied in the development of nutritional and feeding strategy.
