There’s no requirment to register all of your goats in Canada. If you’re looking for high quality stock you could look up the CMGA members in your area and call or email them, that would be a good place to start. Do your research and ask the breeder about what’s important to your herd to see if thier animals would be suitable for your operation, maybe that particular breeder raises show quality stock and you want commercial animals and it wouldn’t make sense for you to purchase expensive purebreds. The only way to be sure of pedigree is to purchased registered boer goats, you can access the pedigree of registered Boers in Canada on the Canadian Livestock Records Corporation website so you know the background of the stock you’re buying.
