The grazing animal, in most natural situations, has a complex environment in which to live. Figure 1 illustrates the multitude of factors that can influence the selection and composition of any day’s diet. Selective grazing by ruminants has been extensively reviewed by Arnold (1963) and Heady (1964). This review will indicate the present state of knowledge of the interactions between plant and animal characteristics in selective grazing. Palatable, by definition, means “pleasant to the taste”. The term palatability has been widely used to describe all the ‘characteristics, not taste alone, that make a plant acceptable to the grazing animal. In this paper, the expression “acceptability” is used to describe the degree to which a plant is acceptable to an animal. The animal itself expresses preferences when presented with a number of species in a plant community; these preferences can be arranged in an order of relative acceptability, i.e. a preference ranking. The reader is referred to study selective grazing. to Heady (1964) for a discussion on techniques used. Fig. 1.-Diet selection by the grazing animal; |
