I have read that you need to feed a pig a certain amount in pounds of grain to get them to butcher weight. Also that if you do grain free grazing them it will just take longer. Can you raise a pig during the fall and winter without grain or with very little grain? I'm not sure how much they will need to eat. It is okay that they grow slower, we are in no hurry for that, but we don't want to be cruel and keep them just barely alive without/or with little grain? We have a couple of pastures that are stockpiled (?) (haven't been grazed on for awhile so might have food they could eat on that we could rotate them around in) and one nice pasture and could also move them around over our large garden so they could till it up and graze on all the things left in it. We also generate quite a bit of kitchen scraps and milk wastes...I would estimate an ice cream tub of scraps could be counted on daily and a gallon of milk products a day. Would that be enough for them all together?? Would they need grain also? THank you!
