Table 7 Sow traits and litter characteristics for the two study groups (C = negative control group, received no feed additive and 1,25-vitD = 1,25-vitD group, received a defined amount of 1,25-dihydroxyvitamin D3-glycosides: 1th to 84th gestation day: 26 g 1,25-vitD per day; 85th gestation day until farrowing: 30 g 1,25-vitD per day; during the lactation period: 70 g 1,25-vitD per day). Asterisk and bold represent significant differences between the two study groups (p < 0.05)
