Hey there, I am new to the pig world and am full of questions! I have heard that when a meat pig gets to old/big she will not breed any more. My brother had a 700 lb sow that would not breed any more. I would like to get a sow, and harness train her, and breed her, and be able to keep her as a usefull farm anamal for a long time. So how long would that be in your opinion. The piglets I can get around hear do not seem to have any breed name, and they cost about $50. Would getting a runt make a differance? Would she stay smaller,and therfore usefull for longer? And what type of outdoor fencing do pigs need? Any input would be great, Thank you!
