Analysis of variance (with room, parity, sow diet, and their interactions as effects); the interactions were non-significant, therefore, they were removed from the model.
Analysis of variance (with post-weaning treatment as effect; initial body weight was used as covariate).
LSB, control diet + 2 × 109 CFU/kg in lactation, creep and pre-starter feeds, and 1 × 109 CFU/kg in starter feed of Saccharomyces cerevisiae var. boulardii CNCM I-1079; CON, control lactation/post-weaning diets; BW, body weight; ADG, average daily gain; ADFI, average daily feed intake; FCR, feed conversion ratio.
