I'd be concerned about nutritional deficiencies in your rats, honestly- depending on the age you feed them, that may or mya not matter, but biomagnification and all, I'd be somewhat concerned. If you're just feeling pelleted alfafa, yes, you can probably use it similarly but still...
Rats' digestive systems aren't nearly as long as rabbits, so they're not as able to digest grasses. Seeds, nuts, fruits, and insects are more their wild diet. That would be my concern. (I'd also suspect you are seeing losses from them eating weaker babies to supplement their own protein needs, which is something that shows up early on with rats who have deficiencies. Discovered this the hard way myself using a home-blended pet rat diet that is no longer recommended.)
