摘要
The aim of this study was to assess the impact of Bacillus-based probiotic diets on reproduction performance, fecal scores, microflora, and economic factors in lactating sows and suckling piglets across two productive cycles. A total of 96 sows, reared in a continuous farrowing system for two full cycles, were divided into two groups: a control group and an experimental group. Sows were fed a basal diet without the probiotic or a diet supplemented with viable bacterial spores. At seven days of age, control group piglets were offered standard creep feed, whereas piglets in the experimental (probiotic) group received a diet containing the probiotic fed to their dams. Sows receiving probiotic-supplemented diets were characterized by significantly higher (p ≤ 0.05) average daily feed intake in lactation, lower (p ≤ 0.01) body weight (BW) loss during lactation, and reduced loss of backfat thickness as well as higher body condition score after lactation. Dietary probiotic supplementation increased (p ≤ 0.01) birth weight, total creep feed consumption, litter weight gain, and piglet weaning weight. The probiotic also improved (p ≤ 0.01) overall fecal scores, decreased total E. coli count on day seven and Clostridium perfringens count (trend) in sucking piglets. The total feed cost per weaned piglet was lower in the experimental (probiotic) group. Supplementing the diet with a probiotic containing Bacillus strains improved the reproductive performance of sows and the performance and health of piglets.

这项研究的目的是评估基于芽孢杆菌的益生菌饮食对哺乳生殖表现，粪便得分，微生物和经济因素的影响，在两个生产性周期中哺乳和哺乳小猪中的影响。总共96种母猪在一个连续的配音系统中饲养两个全周期，分为两组：对照组和一个实验组。在没有益生菌或补充有生存的细菌孢子的饮食的基础饮食中喂养母猪。在7天大的时候，提供对照组的仔猪标准蠕变饲料，而实验（益生菌）组中的仔猪接受了含有益生菌喂养到其大坝的饮食。接受益生菌补充饮食的母猪的特征是在泌乳时显着较高（P≤0.05）的平均每日饲料摄入量，较低（p≤0.01）体重（BW）在泌乳过程中损失，并且降低了背部厚度的损失以及较高的身体状况以及较高的身体状况哺乳后得分。饮食益生菌补充剂增加（p≤0.01）出生体重，总蠕变饲料消耗，垃圾体重增加和仔猪断奶体重。益生菌还改善了（P≤0.01）的总粪便评分，在第七天和灌注仔猪中的灌注体计数（趋势）降低了大肠杆菌的总数。在实验（益生菌）组中，每只断奶小猪的总饲料成本较低。用含有芽孢杆菌菌株的益生菌补充饮食改善了母猪的生殖性能以及小猪的性能和健康。
