1. The paper deals with aspects of energy and protein transformations in the rumen and the absorption of nutrients, and how chemical and physical treatment of the diet may alter such processes. 2. Three techniques are described for dtermine the energy lost within the rumen and small intestine, the volatile fatty acids produced within the rumen and the quality of dietary and microbial protein entering the small intestine. 3. Three diets were prepared from an S24 perennial ryegrass sward. The grass was ensiled directly (silage) or sprayed with formaldehyde solution prior to anaerobic storage (grass + F). An additional diet was prepared by taking the grass + F diet after 90d storage and drying in a high-temperature drier (grass + F - D). All three diets were fed (1000 g DM) in turn, to sheep equipped with re-entrant cannulae at the proximal duodenum and the terminal ileum. 4. Formaldehyde treatment of the grass (grass +F) reduced the extent of energy digestion occurring within the rumen, whils dehydration of this material (grass) + D - D) reduced the extent of digestion even further. Total VFA production rates were not markedly influenced due to formadehyde application. 5. Levels of amino acid consumed were higher on the two formaldehyde diets (150 g and 178 g/d) compared with the silage diet (127 g/d), this difference being attributed to the extensive proteolysis known to occur in the ensilage process. These differences were reflected in the levels of amino acids entering the small intestine, but there was no significant differences in the quantity of amino acids absorved from the small intestine on the three diets. 6. The quantity of microbial protein entering the small intestine was markedly reduced on two formaldehyde treated diets (silage, 112 g/d; formaldehyde diets 35 g/d), indicating marked differences in the rumen fermentation patterns established on the three diets.
