Forages Is Grass okay to feed piggies?

[gingging]

Hello, does anyone know if Carabao grass or this type of grass is good to feed my piggie daily? I live in a tropical country in Asia and timothy hay is not very accessible. We have a huge lawn where I let them roam around and they really like eating the grass, I'm not sure if it's okay for them to eat. We don't use any fertilizers or anything. Google says it's fine but I'm still skeptical.

P.S. - I included a photo of my piggie judging me she's giving me the side eye

There was a discussion about Carabao grass on one of the forums. It was about 10 years ago and is no longer active, but here’s a link: Carabao Grass

Apparently it grows well in the Philippines and some Guinea pig owners there are feeding it.
