Dairy production plays a fundamental role in the Brazilian economy, and high-17 quality forage is necessary for ruminants to produce satisfactory milk levels, so the aim of the 18 present study was to evaluate the production and quality of Jiggs bermudagrass and its effects 19 on the production and quality parameters of milk from Holstein cows under an intermittent 20 grazing system throughout the year. The experiment was conducted in a randomized design 21 with the four seasons as treatments was replicated five times. The season had a significant 22 effect on the production and nutritional parameters of Jiggs bermudagrass with the highest 23 total dry matter production observed during summer followed by spring and fall. The neutral 24 detergent fiber and acid detergent fiber contents were significantly higher in winter. The In 25 vitro dry matter digestibility was significantly higher in summer, spring and fall.
