Recent studies have shown that probiotic supplementation during late gestation exerts some beneficial effects on reproductive performance of the sows. This study aimed to investigate effects of QST 713 supplementation in gilts on different reproductive criteria. A total of 94 Camborough-48 gilts at day 85 of gestation were randomly allocated into 2 groups: (1) control diet; (2) control diet + 4 × 10 CFU QST 713 per day. Gilts were supplemented until farrowing. At farrowing, litter size, number of piglets born alive, stillbirths, mummies, birth weight, farrowing duration, and birth interval were recorded. Within litter variation of piglet birth weight, depicted as SDBW and CVBW, was also calculated. Results showed that QST 713 supplementation decreased stillbirth rate (1.26 vs. 4.37%, =0.035) and increased birth weight of the piglets (1303.94 vs. 1234.09 g, =0.007). Also, the litter size (11.85 vs. 10.67, =0.03), number of piglets born alive (11.71 vs. 10.23, =0.008), and litter weight (15473.06 vs. 13174.86 g, =0.002) in the treatment group were higher than those in the control. Farrowing duration (174.39 vs. 160.81 minutes, =0.162), birth interval (16.32 vs. 16.59 minutes, =0.674), SDBW (85.07 vs. 94.65 g, =0.343), and CVBW (6.42 vs. 7.85, =0.12) were independent of the QST 713 supplementation. Results of the present study indicate that supplementation of QST 713 during late gestation in gilts reduces stillbirth and increases birth weight thereby improving their reproductive performance.
最近的研究表明，妊娠后期补充益生菌对母猪的繁殖性能有一些有益影响。本研究旨在调查在后备母猪中添加QST 713对不同繁殖指标的影响。总共94头妊娠85天的坎波洛48系后备母猪被随机分为2组：（1）对照日粮；（2）对照日粮+每天4×10CFU QST 713。后备母猪一直补充到分娩。在分娩时，记录产仔数、活产仔猪数、死胎数、木乃伊数、出生体重、分娩持续时间和产仔间隔。还计算了仔猪出生体重的窝内变异，用标准差出生体重（SDBW）和变异系数出生体重（CVBW）表示。结果表明，添加QST 713降低了死胎率（1.26%对4.37%，P=0.035），并增加了仔猪的出生体重（1303.94克对1234.09克，P=0.007）。此外，治疗组的产仔数（11.85对10.67，P=0.03）、活产仔猪数（11.71对10.23，P=0.008）和窝重（15473.06克对13174.86克，P=0.002）均高于对照组。分娩持续时间（174.39对160.81分钟，P=0.162）、产仔间隔（16.32对16.59分钟，P=0.674）、SDBW（85.07对94.65克，P=0.343）和CVBW（6.42对7.85，P=0.12）与添加QST 713无关。本研究结果表明，在后备母猪妊娠后期添加QST 713可降低死胎率并增加出生体重，从而改善其繁殖性能。
