A B S T R A C T The objective of this study was to evaluate the effects of two bacillus strains probiotic (BP) supplement on reproduction performance, nutrient digestibility, blood profile, fecal noxious gas emission, and fecal microflora in lactation sows, and growth performance in their piglets. A total of 24 multiparous sows (Landrace × Yorkshire) and their litters were used in a 28 d experiment. On 111 d of gestation, sows were randomly allotted to three dietary treatments with 8 sows and their litters per treatments. The dietary treatments were as follows: 1) control (CON): basal diet, 2) BP0.1: CON + 0.1% two bacillus strains probiotic; and 3) BP0.2: basal diet + 0.2% two bacillus strains probiotic. The body weight (BW), feed consumption, and backfat thickness of sows were checked. Number of piglets born, live, stillbirth and mummification were also recorded to calculate the survival rate after farrowing. Individual piglet BW was assessed to calculate average daily gain (ADG). Flesh fecal samples was collected to evaluate apparent total tract digestibility (ATTD), fecal microbial and gas emission. Supplementation with the BP linearly increased the piglets BW at 21 d and 25 d (P
