Welfare of pigs on farm

EFSA Journal, Volume 20, Issue 8, August 2022., 2022
Abstract This scientific opinion focuses on the welfare of pigs on farm, and is based on literature and expert opinion. All pig categories were assessed: gilts and dry sows, farrowing and lactating sows, suckling piglets, weaners, rearing pigs and boars. The most relevant husbandry systems used in Europe are described.
