Three field grasses: orchardgrass, timothy and perennial ryegrass (with 2 varieties in each species) were harvested at different dates from 19th May to 23rd June. Nutrient digestibility was determined in a feeding trial on 24 wethers of about 50 kg of body weight, fed ad libitum. The linear increase with time of dry matter yield of all grass species during spring season was stated as well as the significant diminishing of their nutrient digestibility and nutritive value. The period before grass heading stage was determined to be an optimal harvesting time
