The seasonal trend of the chemical composition and digstibility of mixed pasture herbage

The seasonal trend of the digestibility of young mixed pasture herbage by steers and sheep, and its chemical composition are reported. A definite seasonal trend of the digestibility of the herbage studied cannot be established, at least for regions where climatic conditions are as variable from year to year as they are at Macdonald College. The digestibility of artificially dried herbage was not changed after six months storage. None of the chemical entities studied gave any indication of nutritive value, and crude fibre and crude protein may be very misleading if used as indices of nutritive value for mixed pasture herbage
