Different hays - nutritional breakdown

Anyone have or know where to find the nutritional breakdowns (including calcium) of different hays, like Oxbow timothy, meadow/rye etc? Obviously it varies, but I'm interested in the rough nutritional content.

It's actually for the guinea pigs I'm interested, but I put it in Rabbit Chat as it's also relevant in there!

Thanks

This was the only info I was able to find a while ago

Thanks for that - very helpful.

I'm also wondering about protein content....

Just realised, I should have put this in the diet section - oops!!

:wave: Bit time consuming but oxbow have some info on their site if you click on each hay type

Thanks

Doesn't seem to be much between them... :?

I guess the best thing to do is feed a variety. Dusty has 4 different hay types (she'd get so bored otherwise, since she can't eat veg or pellets), and the piggies eat absolute stacks of Oxbow timothy, plus dust free hay.
