Description

In conditions of pasture feeding sward selection and con­sumption by grazing animals is strongly influenced by char­acters of herbage (Forbes, 1986). Quantitative and qualitative state of the sward affects its consumption primarily through changes of such elements in animal behaviour as grazing time and number and size of bites (Hodgson, 1982, 1985). Rela­tivelyt much research has been done to investigate the response to the grazed sward of such ruminants as sheep, while the response of cattle, and particularly of dairy cows, has received much less attention (Arnold, 1981 ; Holmes, 1980). This paper presents results of investigations on the effect of sward botanical composition and herbage daily allowance on the quantity of herbage consumption and grazing behaviour of dairy cows. Experiments presented in this paper constitute a part of a long-term project on interrelationships between the sward and grazing animals.

The Effect of Daily Herbage Allowance on the Ingestive Behavior of Dairy Cows

In conditions of pasture feeding sward selection and con­sumption by grazing animals is strongly influenced by char­acters of herbage (Forbes, 1986).
