How many piglets die before weaning?
Besvaret 26. oktober 2026
Of the piglets born in Danish sow herds in 2025, a total of 20.3 percent died before weaning, stillborn piglets included. The figure comes from the farm sector's annual count, based on 703 sow herds. It was produced by SEGES Innovation and paid for by Landbrug & Fødevarer, the Danish farm and food industry body. On average a sow had 20.6 piglets per litter, and 16.4 were weaned. The Danish National Audit Office cites a higher figure from the sector's own data, about 25 percent in 2024, and says mortality was about 17 percent in the early 1990s. The most common direct cause is the sow lying on the piglets, but cold, hunger and small, weak piglets also play a part. The EU food safety authority EFSA says large litters often hold more piglets than the sow has teats, and piglets without a teat typically starve to death before they are four days old.
