Extract

Intake of herbage by grazing animals is determined by the weight of herbage harvested per bite and the number of bites taken. A knowledge of ingestive behaviour can, therefore, play a valuable role in understanding animal responses to changes in sward conditions and management practices and thus aid the interpretation of results from grazing experiments. This paper will firstly consider briefly some methods of recording behaviour and, secondly, present some results illustrating the use of behaviour recording within a grazing experiment.

Direct observation is the most frequently used method of recording behaviour. It is, however, laborious and often carried out under unpleasant conditions; it is difficult to record activities continuously and in some cases it is not possible to directly observe a particular behaviour. These limitations have led to numerous attempts to record grazing behaviour automatically.
