The influence of concentrate intake on the subsequent intake of hay was investigated in sheep fitted with a rumen cannula and electrodes on the reticulum wall to measure volatile fatty acids concentration and reticular motility, respectively. In sheep fasted during night time, a previous meal of concentrates given 30, 60 or 120 min before feeding hay, did not modify significantly (p less than 0.05) the first hour and the first 3 hour intake of hay despite a large increase in ruminal total volatile fatty acid concentration. However, the daily intake of hay was significantly (p less than 0.05) reduced. Similarly, the reticular motility in response to feeding hay was not affected by the previous meals of concentrate. It is concluded that in fasted sheep on a hay ration the short-term satiation of a hay meal is not affected by foregoing intake of concentrates and that the hay intake is not controlled by ruminal volatile fatty acid levels.
对安装有瘤胃瘘管和位于网胃壁的电极（分别用于测量挥发性脂肪酸浓度和网胃运动）的绵羊，研究了精料采食量对随后干草采食量的影响。在夜间禁食的绵羊中，在饲喂干草前30、60或120分钟给予先前的精料餐，尽管瘤胃总挥发性脂肪酸浓度大幅增加，但干草的第一小时和前3小时采食量并未显著改变（p<0.05）。然而，干草的日采食量显著降低（p<0.05）。同样，对饲喂干草的反应，网胃运动不受先前精料餐的影响。得出的结论是，在以干草为日粮的禁食绵羊中，干草餐的短期饱腹感不受先前精料采食量的影响，且干草采食量不受瘤胃挥发性脂肪酸水平的控制。
