Abstract Background Pre‐weaning group housing for sows and their litters is expected to enhance animal welfare. However, knowledge of potential benefits of pre‐weaning socialisation for piglets after weaning is still lacking. Methods Weaner pigs were mixed in groups of 10, using littermates (LM) from pre‐weaning group housing (Gr) and from farrowing pens with crates (Co). Groups were formed as follows: Gr/Gr (5 LM from Gr + 5 LM from Gr), Gr/Co (5 LM from Gr + 5 LM from Co), Co/Co (5 LM from Co + 5 LM from Co). Results During 24 h after mixing, piglets in Co/Co fought more than in Gr/Co and Gr/Gr. Piglets in Co/Co had more unclear fighting results than in Gr/Co and Gr/Gr. Four days after mixing, piglets in Co/Co were more injured than in Gr/Co and Gr/Gr. Conclusion Early socialised piglets may have better social skills when meeting familiar and unfamiliar conspecifics after weaning.
