Stochastic models of grazing behaviour in sheep

Applied Animal Behaviour Science, 1991
Abstract Three models, the multinomial, the Markov process and the age-dependent process, were used to simulate the behaviour of grazing sheep ( Ovis sp.). These simulations were compared with data for sheep grazing perennial ryegrass ( Lolium perenne L.) or white clover ( Trifolium repens L.) swards.

Grazing Behaviour of Dairy Cattle in the Tropics

Nature, 1951
COMPREHENSIVE studies have been made of the grazing behaviour of cattle in countries with a temperate climate, and the literature on the subject has been ably summarized by Johnstone-Wallace and Kennedy1, Tribe2, and Worden3. There are, however, no references in the literature to similar studies in the tropics; and information available on the ...

Effect of previous grazing experience on the grazing behaviour of lambs

Applied Animal Behaviour Science, 1992
An experiment was conducted to evaluate the effects of controlled grazing experience, acquired at two different ages, before or during weaning, on initial acceptance of pasture and on forage preferences of weaned lambs. Forty lambs with their dams were exposed to either white clover (WC) or ryegrass (RG) pastures for 7 days, 1 h day−1, at either 14 ...

Grazing behaviour

Proceedings of the British Society of Animal Production (1972), 1986
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 ...

Grazing management practices and their relationship to the behaviour and grazing habits of cattle

The Journal of Agricultural Science, 1944
1. The grazing habits of Aberdeen-Angus and Hereford beef cows, on pasture without supplementary feed, were studied over continuous periods of 24 hr. during the months of July, August and September. The pastures were from 3 to 7 acres in extent and contained a good growth of Kentucky bluegrass and wild white clover, with an average moisture content of ...

Studies in grazing behaviour of dairy cattle: II. Bloat in relation to grazing behaviour

The Journal of Agricultural Science, 1954
1. Four trials on methods of bloat-prevention vare described: (a) A comparison of ‘break’ grazing and normal ‘rotational’ grazing without restriction of feed in either case. Break grazing observations covered two and five breaks per day.(b) A comparison of these two systems where ‘break’ grazing involved restriction of area available to the cows, and ...
