This is a major barrier for obtaining a predicted high growth potential for organic pig production. The high mortality rate seems to be related to litter size, beyond the size that can be fostered by the sow and birth of weak pigs. The current breed combination may be less suited for organic production, where sows farrow in in-accessible hutches, having long lactations and with limited possibilities for managing surplus piglets. The project facilitate a reduction in neonatal organic piglet mortality from 33 to 20 % of total born piglets, one extra weaned pig per litter and a one extra kg in average weaning weight. Implementation of these results will increase societal trust in organic pig production due to improved animal welfare.
