Boy, that looks like yummy hay! My common bermuda is much browner looking than that. But they eat it, and it’s VERY low carb, so that’s all that matters I guess. But I’m sure they’d tell you different if you did a blind taste test. I guess it’d be like the difference between giving me a rice cake and a yeast roll with butter. ;o)
Our local hay often looks like what you describe... and they don’t eat half of it... they pick around in it, and pee poop on the rest. I just felt like I had to feed a lot of it for them to find enough they liked, and there was a lot of waste.
