Effect of Varieties and Silage Quality of Winter Crop on the Palatability of Calves
This experiment was conducted to determine the effect of varieties and quality of winter crop on palatability of calves for two years. Four Italian ryegrass variety(Kospeed, Kogreen, Kowinearly and Hwasan 101ho), two barley(Youngyang, Yuyeon), and a rye(Winter green) were cultivated at experimental field of National Institute of Animal Science, Cheonan. Four early varieties(Kospeed, Kogreen, Kowinearly and Winter green)were harvested at 20th. Dry matter yield of Hwasan 101 ho was 18,629kg/ha (12,141+6,488) and Yeongyang, Youyeon and Winter green were 14,182, 12,487 and 10,935kg/ha, respectively. Moisture content of Hwasan 101 ho was 81.5% in harvesting time, but wilting for 24 hours might bedecrease moisture content by 65.5%. The relative intake of Hwasan 101 ho, Kowinearly, Kospeed and Kogreen were 34.5, 60, 19.8, 15.7%, respectively. Among forage crop species, relative intake of Italian ryegrass(Hwasan 101 ho), barley(Yeongyang and Youyeon), and Rye(Winter green) were 43.1, 20.9,20.5 and 15.5%, respectively.
