Abstract	The aim of this experiment was to study the performance of Orchard grass (Dactylis glomerata L.) based on herbageyield and quality under different grazing management. Three frequencies (2, 3 and 4 wk in spring and summer and4, 5 and 6 wk in fall) and two grazing intensities (hard: 3 to 5 cm and lax: 6 to 8 cm of residual sward height), ina randomized block design with three replicates, distributed in a 2 x 3 factorial arrangement. Cumulative herbageyield (CHY), net herbage accumulation rate (NHAR), morphological composition and herbage quality were evaluated.The highest CHY and average NHAR were recorded with hard grazing every 4 and 6 wk. The highest seasonal herbageyield (7,844 kg DM ha-1) and NHAR (107 kg DM ha-1 d-1) were observed during summer with hard grazing every 4wk (P 0.05).Across all seasons, hard grazing gave higher forage yield than lax grazing, being different in spring and summer(P<0.05). In overall, total protein and in vitro dry matter digestibility tended to decrease as grazing interval increased,being on average 20 and 65 %, respectively. It was concluded that to obtain the highest herbage yield and quality,orchard grass must be grazed hard every 4 wk in spring-summer and every 5 wk in fall.
