Abstract
The digestibility and intake of several kinds of hay cut at several stages of growth were estimated with sheep. Digestibility in vitro was estimated by a 2-stage procedure. Because the digestibility of dry matter in vitro was unduly affected by a high solubility of ash, digestibility of organic matter was preferred. Digestibility in vitro was estimated after fermentation for 6, 12, 24, 48 or 96 h.
