BW = body weight; ADG = average daily weight gain; SEM = standard error of the mean.

^a,b Different letters indicate significant differences between the 2 data.

¹CON, sows were fed a base diet; SA, sows were fed a basal diet supplemented with 0.1% sodium acetate (n = 40).

²The weight per litter was divided by the number of pigs to calculate piglet BW and then piglet ADG, n = 40.
