摘要

abstract_textpIn this study, we describe HerbValo, which is both a calculation method and a tool that can be used on commercial farms to track the amount of pasture grazed annually in each paddock. At present, HerbValo can be used for dairy cow, suckling cow, or dairy goat operations. First, farmers record grazing or cutting events that take place in each paddock throughout the year. Then, an Excel spreadsheet is used to directly quantify pasture use (e.g., per year, per season, or per paddock). Essentially, at the end of each rotation, the number of grazing days (herd size x residence time) is multiplied by the mean daily intake per animal (estimated using a simplified version of the INRA "Fill Unit" System), which is obtained from data that are easily acquired on farms and by taking into account mean herd traits, pasture type and quality, and grazing intensity. There is no need to measure pasture characteristics directly. The widespread use of HerbValo should yield region-specific reference values for livestock grazing and help identify farming practices that can render pasture use more efficient./p/abstract_text
