Weaning and nursery
After weaning, the piglets are moved to the nursery department and the sows are taken to the fertilisation department to await their next estrous cycle and insemination, which occurs within a few days of weaning. The piglets are in the nursery department for 5–6 weeks until they reach a weight of approximately 27 kilogrammes. At this point, they are transferred to the fattening departments of pork breeding facilities or to fattening piggeries by Atria's transportation contractors. Each sow has 2.3 litters per year on average. The best sows farrow more than ten times in their lives, although sows normally only farrow 3–5 times.
