The aim of this thesis was to examine the project Luomussa vara parempi – ruokaa ja digi hyötykäyttöön (LuoVaPa) results of the first summer of organic grazing. The organic and rotational grazing are introduced generally in this thesis. The herbs of this grazing trial and their use and benefits in animal nutrition have been described. The use of rye in establishing the pasture has also been explored. The three-year project is funded by Centre for Economic Development, Transport and the Environment of Häme region. The objective is to enhance the organic production, processing, availability and the use of organic production in Häme. The participants of the project are Mustiala educational and research farm of Häme University of Applied Sciences (HAMK), ProAgria Southern Finland, Natural Resources Institute Finland (Luke) and Salpaus Further Education. The goal of Mustiala educational and research farm in Tammela is to find suitable, versatile and sustainable plant mixtures for grass and new regenerative ways for organic farming in Häme. The first trial of this project was establishing a pasture with rye as a cover crop at Mustiala in summer 2019. There were also herbs as chicory, birdsfoot trefoil, caraway and plantain with grasses and clovers sowed to the pasture. The milking cows grazed in five paddocks of pasture which were changed daily. Grazing and the growth and condition of the stripes were examined. The daily milk yield per cow was recorded by automated milking system. Grass samples from the paddocks were taken and analyzed for chemical composition and feed values several times. Also botanical analyses were conducted. The cows grazed lazy most likely for the hot summer, but the young rye sprouts seem to be palatable. There was enough forage in both stripes for the whole experimental period. The strongest growth was examined of chicory and plantain. The D-value maintained more stable in the pasture of the stripe 1 than in the pasture of stripe 4. It was probably due to the herbs and the rye in pasture. The potassium concentration of the forage in stripe 1 was too high for milking cows. The sowed rye variety was not suitable for pasture because it spiked already at Midsummer. No remarkable changes in milk yield were observed.
