Three experiments were conducted to evaluate the effect of coated sodium butyrate (CSB) supplementation to peripartal and lactating sows and nursery pigs on lactation performance and nursery growth performance. In Exp. 1, a total of 43 gestating sows (d 81–92 of gestation) were allotted to 0 (n=15), 500 (n=16), or 1000 (n=12) ppm of CSB supplementation based on breed, parity and body weight (BW), and then fed treatment diets until weaning. In Exp. 2 and 3, a total of 144 weanling pigs (72 pigs for Exp. 2 and 3, respectively) from 0 or 1000ppm CSB sow treatments in Exp. 1 were allotted within the sow treatment to 0, 500, or 1000ppm of CSB supplementation in nursery diets based on breed and BW in a split plot design for a 35-d growth study. All pigs in Exp. 2 were injected with ovalbumin at weaning and d 14 postweaning as an immune challenge. In Exp. 1, there were no differences in sow BW, litter size, litter weight, lactation feed intake or milk composition among treatments. However, colostral IgG (P=0.06) and IgA (P=0.09) concentrations tended to increase quadratically as CSB supplementation levels increased. In Exp. 2, pigs from the 1000ppm CSB sow treatment had greater BW at d 35 (P
