Description
Production by ruminants on high forage diets is often limited by intake. If fill limits intake, residue must escape the rumen through digestion or passage for further intake to occur. Resistance to escape of forage residues from the rumen is a function of physical and morphological characteristics of the forage, although the nature of the relationship is not fully understood (Moseley and Jones, 1984). Understanding of factors affecting passage of undigested residue is important to ensure maximum forage utilization in ruminant diets. It was hypothesized that differences in forage morphological composition, particle length and rates of passage of morphological components are primary factors affecting retention time of matter in the rumen. Objectives were to : 1) determine particulate and fluid mean retention time (MRT) in 12 grass hays from four sources at two levels of offer and 2) relate differences to morphological composition of hays and to differences in particle length and morphology of particles.
