Carbohydrate Composition in Relation to Pasture Quality
THE TERM “pasture quality” is a measure of the ability of the pasture to provide the nutritive requirements of the grazing animal. Many plant constituents contribute to this policy but only one group, the carbohydrates, will be considered here. At present probably the only reliable and meaningful method of assessing the relative nutritive value of different pastures is by comparing actual anima...
متن کاملIdentification of hyperspectral vegetation indices for Mediterranean pasture characterization
A field experiment was carried out to assess biomass and nitrogen status inMediterranean pastures by means of hyperspectral high resolution field radiometric data. Spectral and agronomic measurements were collected at three different pasture growth stages and in grazed–ungrazed plots distributed over an area of 14 ha. Reflectance-based vegetation indices such as simple ratio indices (SR[i,j]) a...

15 صفحه اولPasture Quality Measurement Tools for Decision Making
Pasture quality is an important component in grazing and livestock management and a key driver of animal performance. Accurate, real-time information on pasture quality can help farm managers in decision making. This study investigated the potential applicability of optical sensors to estimate pasture quality parameters in the field, these have been trialled as part of the P21 Feed Programme, c...
متن کاملRoute Choice in Hilly Terrain
The orienteering route choice problem involves finding the fastest route between two given points, with running speed determined by various properties of the terrain. In this study we consider only the effect of climbing or descent on running speed. If a runner’s pace p (the reciprocal of running speed) varies linearly with gradient m, the straight-line route is always fastest. This may be a re...
