Spatial distribution of forage intake by grazing beef cows on an alpine pasture in Japan

摘要：

In an extensive grazing system,estimating spatial distribution of forage intake by cattle can provide valuable information for pasture management and cattle nutritional management.Animal distribution and movement can be traced using global positioning system (GPS) units along with a geographic information system (GIS).Grazing behavior such as biting and chewing can be successively recorded by acoustic biotelemetry ( Laca et al.,2000 ).Forage intake by grazing cattle under an extensive system can be estimated by the single‐pulse dose method ( Nakano et al.,2008 ).Combining these methods may enable us to estimate spatial distribution of forage intake by grazing cattle.The aim of this study was to estimate spatial distribution of forage intake by cattle and to discuss the influence of seasonal distribution patter of grazing behavior on forage intake.
