They'll eat it and it has a superior root system for drought tolerance compared to the cereal grains.

They've been munching on it pretty hard here the past few weeks.

P.S. There's no difference in the nutritional content between Gulf, Marshall, & Passarel ryegrass. (according to my forage test results)

The only difference that I've found is the latter two stays green about 2-3 weeks longer in the Spring.
