Your question is just a little too open ended. What, exactly do you want to know? I've raised Boer for about 9 years now. Like all goats, they need good fencing, regular deworming and foot care. I feed mine good hay and a pelleted ration made specifically for goats. It has all the vitamins and minerals they need, but I still offer a mineral block as well. I would prefer to offer loose mineral, but my pelleted feed has selenium added so I need a mineral that doesn't have it and the block was all I could find.
If you have any specific questions, feel free to ask here or contact me privately.
