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 < 0.05), and ADG during different grow period (P < 0.05). The ATTD of dry matter (DM) in sow supplemented with BP was linearly improved (linear, P < 0.05). Sows fed BP supplementation diets had a reduction in fecal NH₃ concentration (linear, P < 0.05). At weaning, sows fed with the BP supplementation diets had reduced E. coli population (linear, P < 0.05). Our results indicated that the BP in sow diets improved DM digestibility, reduced E. coli concentration, and decreased NH₃ and total mercaptan concentrations. Sucking piglet's growth performance was increased by supplementation BP of the sow diet.

这项研究的目的是评估两种乳酸菌益生菌（BP）补充剂对泌乳母猪繁殖性能，养分消化率，血液分布，粪便有害气体排放和粪便微生物区系以及仔猪生长性能的影响。在28天的实验中，总共使用了24头多胎母猪（Landrace×Yorkshire）及其垫料。妊娠111天后，将母猪随机分配给3种饮食处理，每只处理8只母猪。饮食处理如下：1）对照（CON）：基础日粮，2）BP0.1：CON + 0.1％2个杆菌菌株的益生菌; 3）BP0.2：基础饮食+ 0.2％两种益生芽孢杆菌菌株。体重（BW），饲料消耗和母猪的后脂肪厚度进行了检查。还记录了仔猪的出生，存活，死产和木乃伊的数量，以计算分娩后的存活率。评估个体仔猪体重，以计算平均日增重（ADG）。收集粪便样品以评估表观总道消化率（ATTD），粪便微生物和气体排放。补充BP可使仔猪在21d和25d时体重线性增加（P <0.05），而在不同生育期则增加ADG（P <0.05）。补充BP的母猪干物质（DM）的ATTD线性改善（线性，P<0.05）。补充BP饮食的母猪粪中NH ₃浓度降低（线性，P <0.05）。断奶时，补饲BP日粮的母猪大肠杆菌数量减少（线性，P <0.05）。我们的结果表明母猪日粮中的BP改善了DM的消化率，降低了大肠杆菌的浓度，并降低了NH ₃和总硫醇的浓度。通过补充母猪日粮BP可以增加仔猪的生长性能。
