Senior Guinea Pig
Timothy isn't too rich at all, not sure where you heard that, but any of the grass hays are fine for everyday feeding. 
It's the legume hays (alfalfa) that are rich in calcium and protein, so not great for everyday feeding for adult pigs. Dried grasses (Readigrass, Just Grass) are also rich, but fine for everyday feeding once the pig has been gradually introduced to them.
