We investigated the nutritive value and ruminal in situ dry matter degradability of whole crop rice silage prepared using Chucheongbyeo (WCRS) as a roughage source for ruminants. The crude protein (7.54%), acid detergent fiber (29.63%), neutral detergent fiber (62.98%), and total digestible nutrient (TDN) (57.88%) found higher in WCRS than those of rice straw. Manganese content in the WCRS was the highest, followed by carbon, iron, zinc, and copper, but magnesium content was the lowest. Glutamic acid content in WCRS was the highest, followed by leucine, asparagine, alanine, valine, arginine, and methionine content was the lowest. We examined ruminal in situ digestibility from total whole crop rice (TWCR), rice husks containing rice (RHR), whole crop rice except RHR (WER), and husked grain (HG) for 3, 6, 12, 24, and 48 hours. Ruminal in situ digestibility in the HG was the highest, followed by RHR, TWCR, and WER. Therefore, we suggest that ruminal in situ degradability was influenced by parts of whole crop rice, and the content of manganese and glutamic acid were the highest in WCRS.
