I feed my rabbits Albers Rabbit Feed. It's fantastic and I've never had to use any other feed. I agree with the ingredients and everything it has in it. No matter the feed you buy, you should always look for these traits:
16% PROTEIN: Hollands cannot have high protein because they are a small breed. Under 16%, for Holland Lops, is not enough protein for this active breed.
AT LEAST 16% FIBER: Albers Rabbit Feed has between 18% and 21% fiber. The more fiber it has, the least amount of hay you need to feed. Hay should still be in the diet because it's what consists of wild rabbit's diets, and helps keep the teeth at a normal length.
FAT CONTENT: Alber's has 2% crude fat. There should be as little fat as possible, yet still some.
SALT: There should be some salt in the pellets. If there is none, offer a salt spool. Albers has a relatively low salt content which I don't like very much, but treats and oats provides enough salt without the spool.
VITAMINS AND CALCIUM: Vitamins and calcium are optional. Most feeds have added vitamins and calcium, I have never seen a feed without.
TIMOTHY OR ALFALFA BASED: Albers is Alfalfa-based. If you feed an Alfalfa-based pellets, never feed Alfalfa hay.
NO CORN!! : Rabbits cannot have corn. Corn clogs their digestive system and doesn't break down properly in their stomach. In other words, they are allergic to it.
Look for an upcoming post on hay, the best kinds to buy, and the best places to buy hay!
