New systems for the estimation of the protein supply in ruminants, which were recently developed in different countries including Slovenia, demand some additional information which was not required in the old digestible crude protein system. This information includes data on protein degradability in the rumen, microbial protein synthesis in the rumen and digestibility of rumen undegradable protein. There are only a limited number of data for green forage in the literature. Since the published results were obtained mainly on frozen or dried samples their accuracy is questionable. The methodology for determination of the traits mentioned above using fresh forages will be developed in the present project. Changes during the maturation of grassland forage will be quantified. Rationalisation of ruminant feeding during the summer period and the improvement of the quality of agricultural products (protein in milk) will be possible on the basis of the results. With proper supplementation of diets containing green forage it will be possible to reduce the surplus of rumen degradable protein and related ammonia emission to the atmosphere.
