Chemical composition and in vitro digestibility of some weed species during summer

Weed species were collected during the first three months of 1967 at Canberra and arbitrarily divided into those parts that were easily accessible to sheep and those that were not. The digestibility and nitrogen content of whole plants of some weed species and the more readily accessible parts of other species compared favourably with those of sown pasture species and were superior to those of native grasses.
