The Physior livestock operation of Le Gouessant is based on alternative farming practices primarily focused on animal welfare: outdoor access, the provision of straw, and discontinuation of castration and tooth grinding. One objective of the Pig Farming Pilot Project is to assess the welfare of pigs in this operation. This article presents the indicators chosen and the initial results after one year of monitoring during gestation and lactation. To assess the welfare of sows and piglets, several criteria were tracked every month for 72 gestating sows and all sows in the nursery. The cleanliness of pens (by zone of living area) and animals, animal health, lameness, bursitis, and damaged hooves for sows, as well as significant wounds on the legs for piglets, were recorded, along with other injuries (damaged vulva, facial lesions, etc.). During gestation, combat-related injuries were noted, and a human-animal relationship test was conducted. In the nursery, the thermal comfort of piglets was assessed by observing their distribution within the pen. After one year of monitoring (of 237 sows during gestation and 91 in the nursery), the results were conclusive: all animals were rated as clean because the animals clearly identified outdoor access areas as dirty zones and indoor spaces as resting areas. Very few health problems were observed, except for piglets, with 20 % having facial injuries and 10 % having leg injuries. In gestating sows, combat-related injuries were noted, related mainly to competition for access to feeding areas. In addition, 89 % of the sows trusted humans. The distribution of piglets in the nests was satisfactory in 82 % of cases.
