Bunnies: What should I do about faders?

I'm a rabbit breeder who has a few litters with faders. I have a little knowledge on faders. I know that they occur in breeds of rabbit with the dwarf gene. I know that their digestive system is messed up and they have trouble digesting food. Do you suggest I try to save its life, or should I leave it alone? Whenever I try to save it, I always feel like I'm prolonging its life. Please answer! :)
