Extract

Manual separation of both barley and wheat into distinct botanical fractions, with assessment by laboratory techniques, has shown the fractions to have widely different digestibility coefficients (Manley and Wood, 1978). Whole crop cereal harvesting followed by separation of the chopped whole crop into fractions could thus be of benefit to livestock producers. Claims have been made in the farming press (Power Farming, September 1978) by a Swedish company, that one of the straw fractions produced in their centralised separation plant had a higher energy protein content than unfractionated straw. The purpose of this experiment was to evaluate two barley straw fractions produced by a simple air blast separation system, which would lend itself to on-farm use,thus significantly reducing transport costs.
