A review of some factors influencing the intake of food by ruminants is presented. In addition, two sets of experimental results which indicate the complexity of intake control are described :

(1) It was shown that it is possible to product significant intake depressions in sheep by intraruminal infusions of acetic, propionic and butyric acids. Plane of nutrition of the animal plays a large role in the effect obtained. (2) A situation where normal intake pattern appeared to be over-ruled by a transient unpalatability is described. Short-rotation ryegrass was rendered unpalatable to sheep by an accumulation of nitrogenous compounds in the grass following unusual environmental conditions.
