Live weight gain of beef cattle steers on Panicum maximumcv .Tanzania subjected to intensities of rotational grazing

摘要

Herbage intake and animal performance increase with increasing sward height,herbage mass,post‐grazing residue and herbage allowance to a certain limit.This increase tends to a maximum which is specific for a given animal species and category,and defined by the ability of animals to process and,or digest the consumed herbage.Identification of the sward condition at which that response happen allows its comparison with ideal sward targets for efficient harvest of the produced herbage,resulting in the definition of sward target based management strategies that take into account plant and animal requirements.
