The timing of turnout is an important factor affecting the grazing management of dairy cows. However,its consequences are not well known in the short grazing season of northern Europe. Thus, the effect of the turnout date of dairy cows to pasture on sward regrowth, herbage mass production and milk production was studied in two experiments,1)a grazing trial with 16 Holstein-Friesian dairy cows and 2)a plot trial where the treatments simulated the grazing trial.The treatments were early turnout (1 June)and normal turnout (6 June).Early turnout decreased the annual herbage mass (HM) production in the plot trial (P =0.005),but due to a higher average organic matter (OM)digestibility (P 0.05). Although early turnout had no effect on milk yields it meant easier management of pastures.;
