Grazing, in the traditional sense of the term describes the actions of animals that consume parts of plants without causing the death of the plant; for example, the consumption of grass tissue by domestic cattle. By extension, the term applies more generally to any feeding process that involves the partial consumption of the prey organism so as to ...

Grazing and grazing management terminology in southern Africa
Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1967In order to avoid misunderstanding arising in discussions and from the literature on grazing management problems in Southern Africa a proposed list of terms and definitions to cater for all grazing situations and concepts is presented. The terms are classified into two groups, those dealing with properties of the vegetation and those dealing with ...

Ecological Applications, 1993
Grazing is more than just defoliation of plants. The impact of herbivory affects ecosystem structure and function, both above and below ground. Ultimately, effects of herbivory are expressed to varying degrees at many levels of the ecosystem. Herbivory has been shown to affect plant physiology, morphology, and genetics. Plants have evolved many ways to

THE PATTERN OF GRAZING IN ‘CONTINUOUSLY’ GRAZED SWARDS
Grass and Forage Science, 1969The frequency and severity of defoliation of small sample areas, 8 × 8 cm, was studied in swards of S37 cocksfoot which were maintained at different levels of leaf‐area index by continuous grazing with lambs. By varying the number of lambs grazing a plot, the LAI was maintained at three approximately constant levels, 5.3 (H), 4.1 (M), and 3.0 (L).

Graze: A model of selective grazing by beef animals
Agricultural Systems, 1987Abstract A dynamic simulation model has been developed that relates beef animal performance to environment, management practices and selective grazing of pastures. Daily measures of pasture quality and availability are maintained. Measures of the animal's physiological weight and age are computed at 15-min intervals or less, and body composition ...

Grazing-incidence spectrograph
Applied Optics, 1994A novel compact spectrograph, based on double diffraction by a strip-shaped grating at a grazing angle combined with a tuning mirror, is theoretically discussed. In this configuration the emerging light illuminates a large number of grooves, leading to high spectral resolution.

Physics in Medicine & Biology, 1980
The potentialities of photographic transaxial tomographic methods are discussed. It is shown that unfiltered, transaxial tomographic summation images can yield high-quality tomograms of high-contrast objects. A direct and efficient photographic method for recording transaxial tomograms (grazing incidence tomography) is demonstrated, and various means ...

Bale Grazing: Feeding Hay on Pasture Using Rotational Grazing Techniques
XXV International Grassland Congress (IGC 2023), 2023Bale grazing is a novel winter-feeding method where bales are set out on pasture, typically in checkerboard fashion, and fed in a planned, controlled manner, much like rotational grazing. So far, the concept has not been widely adopted in the eastern US, but offers an improved alternative compared to conventional winter-feeding systems for beef cattle,
