Greenfeed oat (Avena sativa) crops are easy to manage, providing a large quantity of good quality winter feed quickly. Oats are usually grazed once or twice. For extra production and grazings into spring Hattrick oats are usually sown with an Italian or annual ryegrass (e.g. Tabu or Archie).
Oats are often compared to ryegrass as a winter crop. Oats produce a larger bulk of winter feed. Italian or annual ryegrass is higher in feed value and can be grazed more times into spring.
