In three - year experiments, carried out on the laboratory scale, Bromus unioloides, Dactylis glomerata and Lolium multiflorum suitability for silage was stated before ear formation /the plants being 30-40 cm high/ as well as at the beginning of ear formation and florescence. It was recorded that as the vegetation advanced the ratio of suluble sugars to proteins increased in grasses whereas the ratio of sugars to the buffer capacity decreased. When preserving grasses harvested at a later date more lactic acid and less acetic and butyric acids were formed and the quality of thsse silages was better. Lolium multiflorum was the best for silage in three - litre jars whereas Bromus unioloides and Dactylis glomerata should not be used for silage when fresh but after previous wilting on swaths to about 30-38% of dry substance. The best time for harvesting of Bromus unioloides, Dactylis glomerata and Lolium multiflorum for silage is the time of ear formation as the green forage ensilaged at the beginning of florescence had insufficient for cattle arnount of protein, phosphorus, magnesium and sodium and too high level of crude fibre.
