Influence of cutting date on the protein quality of forage legumes in the autumn regrowth

摘要：

High crude protein content in binary swards in autumn is the result of the high proportion of forage legumes.This protein may be poorly used by ruminants as it contains large amounts of non‐protein N, which leads to low N use efficiency by the animals.However, differences in legumes in terms of content of secondary plant compounds may be advantageous to avoid excessive N losses in production systems.Secondary compounds of relevance for improved N utilization in animal are the condensed tannins found in birdsfoot trefoil and the polyphenol oxidase found in red clover.The aim of the present study was to measure the variation in forage quality of different forage legumes in the autumn regrowth to find proper harvest management taking into consideration forage legume species and their protein quality.
