For a 3-6 lb. bunny, about 1/3 cuppelletsmore or less (depending on size)isenough--or, as I measure it, 1/2 of a tuna can! I actually fed thatmuch to a 7 lb. older buck, but he wasn't burning calories as fast ashe had when young. For 7-10 lbs. a full tuna can usually keeps a goodweight. This is all assuming the bunny's at a healthy weight for hisbreed.
Itmay seemlike you're starving the little fellas,but really they can
usually keep a healthy weight on that. Justkeep a
very close eye on their weight. Some bunnies, likepeople, have higher metabolism and need more. If you feed Purinapellets, which are high in nutrition, they should be fine.
A bunny that doesn't beg a little in the morning is probably gettingtoo much food. A bunny that tries to rip your arm off to get to thefood either has a mental problem (lol, I've had a couple of those) orprobably doesn't get enough. And the only bunny that gets unlimitedfood is a pregnant or nursing doe. At least in my little herd, anyway!
Feel the ribs. If you can feel the outline of ribs covered by a thinfat layer, that's a healthy weight. If the ribs stick out sharply andthe belly is flabby, sunkenand loose, that's too thin. If youhave to push to feel the ribs and the belly balloons out on the sides,that's too chubby. Only a pregnant doe should feel like that.
And be careful when dieting, because rabbits lose weight incrediblyfast, and gain it fast too. Everything needs to be careful, healthy,and gradual.
Good luck! I did a lot of experimenting to find the rightamount--you'll probably need to do the same. Actually, after 12 yrs.,I'm still tailoring that amount to the weather, season, condition,activity level, etc. etc.!
