In order to study the effects of hay lignin content on the particle size distribution of dry matter (DM), cellulose and acid detergent lignin (ADL) in the rumen, cecum and large intestine (colon and rectum), digestion trial and slaughter experiments were carried out using 8 and 12 sheep, respectively. Animals were given one of two varieties of orchardgrass first cut hay with an ADL content of 4.3% or 8.3% at a level of 2% of live weight. For the slaughter experiment, animals were slaughtered at 2 and 24h after feeding. Digesta from each site in the alimentary tract were totally collected and sieved into 4 fractions such as large particle, medium particle, small particle, and fine particle and liquid fractions by a wet sieving technique. The apertures in the sieves used were 1.180, 0.300, and 0.045 mm
