Keywords: Weaning

L
Intensive pig farming imposes constraints that can be detrimental to the welfare of the pig. In wild boar or domestic pigs in semi-natural conditions, the parturient female lives in a matriarchal group and builds a nest to conceal and protect the young. A bond is established between the sow and her piglets and the suckling period lasts a minimum of 10 to 12 weeks. .... The more premature the weaning, the greater the negative impacts on behavioural and zootechnical disturbances. Proper attention to the animal's welfare calls for precautionary measures to avoid placing the animal in a situation of fear or anxiety and to enable it to express the behaviour deemed normal for the species.
