If your going for meat and brush. You'll want a full bodied tall goat to reach high and have a good slaughter weight. Kiko, and spanish are the best.
I leave off boer goats because of their price. Here in Alabama a boer stud goat sells for around $350-$500.
Females running in the $150-$200 range.
It's really whatever you can afford though. Crosses give really good results and a better of a chance for disease resistance.
Get a really nice buck and just a grab a bunch of craigslist does. You can build up a really nice heard in a few short years. Eat the billies and a few doe culls and keep all your nice does for breeding stock.
Keep an eye on craigslist and all the alabama livestock trader pages on
Facebook.
Don't forget about goat
milk for drinking, cheese, and
soap.
Alpine, and Nubian are great milkers.
