Abstract
This experiment was conducted to evaluate the productivity and silage quality of domestically developed forage crops in Korea. A variety of rye ("Gogu"), oat ("Samhan"), three Italian ryegrass ("Kogreen", "Kospeed" and "Kowinearly") and two barley ("Yuyeon" and "Youngyang") were evaluated at an experimental field of Grassland and Forage Division, National Institute of Animal Science, RDA in Korea. Gogu showed the highest dry matter yield among the forage crop but the lowest was Samhan. Crude protein (CP) was higher in the oat and Italian ryegrass varieties. The total digestible nutrient (TDN) content levels were similar with the except for the rye. The acidity (pH) of the oat silage was the lowest among forage crop species. Higher lactic acid content levels were found in the Kogreen and Samhan compared to the other varieties (p<0.05). According to Flieg's score, all of the silages were assigned a $1^{st}$ quality grade with the exception of the Gogu. These results suggest that domestically developed forage crop varieties show high performance in terms of productivity and silage quality, and are therefore recommendable forage crop varieties for Korea.
