Aspects of Nitrogen Metabolism in Ruminants in Health and Disease

[摘要] Studies in this thesis investigated various aspects of nitrogen metabolism in ruminant livestock. Nitrogen balance and digestive efficiency studies were conducted in order to obtain indicators of the apparent efficiency of absorption and retention of dietary nitrogen, while studies using radioisotopes provided more detailed information on the metabolism of nitrogen. During the course of the work described here techniques were developed for the continuous intravenous and intraruminal infusion of substances into cattle and sheep respectively. A simplified polythene chute system to facilitate the collection of low dry matter calf faeces was also developed.
