What type of feed is best to feed a meat breed of goat? We have thought about getting some in the future, but not sure what is best to feed them?
It's good to bear in mind that meat breeds are supposed to be efficient at turning fodder into meat as cheaply as possible. They're designed with with end commercial result in mind; any meat breed that depends on a lot of supplementary feeding is a poor performer, basically.
Careful breeders will always select those that did the best with the least input, but plenty of people overfeed them on rich foods then think the resulting obese animal is a good example of its breed, and for generation after generation many people will breed on poor quality, poor doing meat animals and use extra aids like cereals, pellets, etc to raise them to the visual/productive standard that they should have been at in the first place without any aids whatsoever.
You can get good meat animals that can get to market weight on the coarsest pastures and scrubs, and you can also get bad meat animals that struggle when fed anything less than the lushest pastures and best supplements... Choose your strain carefully would be my advice. Depends what you're after too; do you just want to 'finish' your own meat animals, or do you want to breed them? The most 'bang for your buck' will come from animals selected to do the best under the harshest conditions, either way, not those for which the breeder always relies on feedlotting to get up to standard weights. Are you happy to spend out on pellets that aren't necessary? Depends what your pasture is like too. Normally, healthy animals should only need decent pasture and possibly a mineral supplement depending on circumstances, and nothing else, to reach a good weight.
If the breeder you buy off habitually feeds them pellets etc despite the pasture being good, they're going to be a drain on your pocket to keep in decent condition. After enough generations they get habituated to the lusher diet, and become less efficient at taking the utmost from natural conditions. They become coddled and can suffer if expected to live more naturally.
If the breeder you buy off gives them a decent pasture and maybe a mineral supplement, (and some other stuff like hay doesn't hurt but shouldn't be what they rely on without drought conditions or over-wet conditions), then chances are you'll get good performers.
I should clarify what a good pasture is, as defined by a goat's needs... It's not necessarily lush green grass and nothing else. It should ideally be a mix of herbs and forbs and grasses and brush/scrub, trees, woody weeds, etc. Not everyone has this obviously and it doesn't necessarily mean their goats are poor doers, but the more 'managed' or 'manicured' their pasture, the softer they are, as a general rule of thumb. Their natural diet is not based on mainly grass at all, as with dogs they ideally should have as natural a diet as possible.
I like your signature line, by the way. So true. True for all livestock and people too but we tend to turn a blind eye to it or forget it, easier to use premixed junk and everyone has different beliefs, some swear by it and think there's no other way.
Chooks n Kids gave a good answer, though I'm not sure what 'goat text' is (autocorrect?)... Personally I wouldn't use pellets again unless desperate due to drought. Turns to mush inside the body, often full of crap, predisposes to health issues (some would argue this point but each to their own), and they do so much better on natural pasture anyway.
Best wishes.
