Three feeding frequencies of late-cut grass hay (two times per day at 8 h interval, once a day, two times per day at 12 h interval) were compared in sheep fitted or not with a rumen fistula. The following parameters were recorded: daily dry matter intake, ingestive activities, reticulorumen load before and after the large meal following each feeding. The daily dry matter intake was not significantly affected by the treatments although it tended to be lower with one only feeding per day. The animals consumed a larger meal after a single feeding in the morning than after two feedings and they thereafter had more small meals during the day. The total time spent eating and ruminating was similar for the three treatments, always with more time spent ruminating in the night than in the day. Whatever the feeding interval (8 or 12 h), the weight of the reticulorumen content was higher after the evening meal.
在装有或未装有瘤胃瘘管的绵羊中，比较了晚割禾本科干草的三种饲喂频率（每天两次，间隔8小时；每天一次；每天两次，间隔12小时）。记录了以下参数：每日干物质摄入量、采食活动、每次饲喂后大餐前后的网瘤胃负荷。尽管每日干物质摄入量在每天仅饲喂一次时往往较低，但各处理间无显著差异。动物在早晨单次饲喂后摄入的食物量比两次饲喂后更多，且之后白天会有更多的小餐。三种处理下进食和反刍的总时间相似，夜间反刍时间总是比白天长。无论饲喂间隔是8小时还是12小时，晚餐后网瘤胃内容物的重量都更高。
