There's a lot of different varieties of that, the stuff our feed store gets is usually second or third cutting, no seed heads, very nearly blue in color.
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)
We got orchard grass shipped here from up north during the drought. It was lovely hay. The feed store still stocks it but it’s very expensive in comparison to our local coastal bermuda. The 12 rolls I just bought was really nice coastal.
