Developments in monitoring grazing behaviour and automated grazing management in extensive systems
2022This chapter provides an overview of the development and use of information technology to improve the management and welfare of grazing livestock under extensive systems. It discusses the evolution of grazing management through the animal/pasture interface, and the development and application of grazing management technologies, including, on-animal ...

Near-Grazing Behaviour of the Harmonic Ocsillator
Volume 7A: 17th Biennial Conference on Mechanical Vibration and Noise, 1999Abstract Impacting systems are intrinsically nonlinear. They are found in a great variety of mechanical constructions. The control of the impact phenomena requires a thorough understanding of the dynamics involved. It is discussed that near-grazing systems, i.e.

A Technique for the Measurement of Grazing Behaviour
1984Equipment to sense and record the jaw movements of grazing sheep is described. The recorded analogue signals are converted to digital form and analysed in a Midas 3 microprocessor. The microprocessor analysis differentiates between jaw movements devoted to prehension and mastication during eating, ruminating and idling, and summates both the jaw ...

Grazing behaviour in New Zealand
The British Journal of Animal Behaviour, 1953Summary o (1) The value to the pastoral farmer of grazing behaviour studies is considered. It is pointed out that an uncritical application to farming practice of results obtained is liable to result in less efficient animal production from grassland.

Grazing behaviour and diet selection by Dorper sheep
Small Ruminant Research, 2000The grazing behaviour and diet selection by Dorper sheep, as well as other related aspects (pasture intake, walking habits and trampling) is reviewed. It was clear that Dorper sheep are less-selective grazers, compared to Merino-type breeds. Dorpers utilised shrubs and bushes to a greater extent, but grass to a lesser extent in relation to Merino sheep.

Vigilance Behaviour in Grazing African Antelopes
Behaviour, 1982AbstractAfrican antelope may devote a large proportion of their foraging time to looking around. The factors affecting such vigilance behaviour are examined for grazing antelope, five species being studied in detail. The proportion of time spent looking decreased as species body weight increased.

Grazing behaviour of a non‐herbivorous characin: revisiting plasticity
Journal of Fish Biology, 2014Feeding behaviour and diet of Bryconamericus microcephalus differed between canopy conditions. At the open canopy site, a behavioural modification, grazing on algae, was observed. This was also reflected in gut content analysis and suggests behavioural plasticity in response to resource availability.

Grazing of heterotrophic flagellates on viruses is driven by feeding behaviour
Environmental Microbiology Reports, 2013Summary The trophic interactions between viruses, bacteria and protists play a crucial role in structuring microbial communities and regulating nutrient and organic matter flux. Here, we show that the impact on viral density by heterotrophic flagellates is related to their feeding behaviour (feeding on sedimented ...

Grazing behaviour of calves reared at pasture
The Journal of Agricultural Science, 19591. Observations were made on the behaviour of young spring- and autumn-bom calves reared at pasture.2. Bucket-fed calves rapidly learnt to graze, whereas single-suckled animals running with their dams made no serious attempt to graze until they were 6 weeks old.3.

Effects of poor forage conditions on the behaviour of grazing ruminants
Tropical Animal Health and Production, 1994This paper shows that the study of animal behaviour is a valuable aid to the improvement of the management of grazing livestock under extensive conditions. The food available to grazing animals in developing countries, and particularly in the dry season in the tropics, is often of very low quality and, in addition, is frequently available at low ...
