The litter size was 11.8 piglets live born, the number of pigs weaned 10.9 per litter and the number of litters per mated sow 2.52 per year. These results are the average of almost 30,000 sows on 20 farms. All farms have a population of 1000 sows or more.

This high production level shows that the TOPIGS 40 sow copes well when performing in a hot climate. Indicators for that are the high percentage of sows bred within 7 days after weaning (93.1%), the high farrowing rate (92.1%) and a sow mortality rate of just 4%.
