本研究旨在评估BioPlus 2B（一种含有地衣芽孢杆菌和枯草芽孢杆菌孢子的益生菌）对母猪及其窝仔的健康状况和生产力的有效性。将总计109头后备母猪和经产母猪分配至两个实验组，如下所示：未处理对照组（UC）和BioPlus 2B（与UC组加BioPlus 2B相同的喂养），剂量为400 g/吨饲料（等于1.28 X 10（6）个活孢子/g饲料）。从分配日（预期分娩前14天）开始给药，直至断奶日。各组的产次均匀性令人满意。从结果中可以明显看出，饲料中添加BioPlus 2B改善了后备母猪/母猪的生产性能，具体表现为：（1）产后前14天母猪饲料消耗量增加;（ii）哺乳期母猪体重减轻减少。某些血液和牛奶参数显着改善，表现为较高的血清胆固醇和总脂质浓度和较高的牛奶脂肪和蛋白质含量在哺乳中期。因此，还注意到窝仔健康和性能特征方面的积极影响：（1）仔猪腹泻评分降低，（ii）断奶前死亡率降低，从而导致每窝断奶仔猪数量增加，以及（iii）断奶时仔猪体重增加。此外，BioPlus 2B倾向于改善母猪的健康状况和生育力，证明：（i）具有乳房炎-子宫-缺乳（MMA）问题的母猪比例较低的趋势和（ii）恢复发情的母猪比例较低。
The aim of this study was to assess the efficacy of BioPlus 2B, a problotic containing Bacillus licheniformis and Bacillus subtilis spores, on the health status and productivity of sows and their litters. A total of 109 gilts and sows were allocated into two experimental groups, as follows: untreated controls (UC) and BioPlus 2B (same feeding as the UC group plus BioPlus 2B) at a dose of 400 g/ton of feed (equal to 1.28 X 10(6) viable spores/g of feed). Treatment started from the day of allocation (14 days prior to the expected farrowing) up to the weaning day. Homogeneity of the groups was satisfied with regard to the parity. From the results it was evident that BioPlus 2B supplementation of the feed improved gilt/sow performance as shown by: (1) the increase of sow feed consumption during the first 14 days postpartum and (ii) the decrease of sow weight loss during the suckling period. Certain blood and milk parameters were significantly improved, as shown by higher serum cholesterol and total lipids concentrations and higher milk fat and protein content at midsuckling period. As a consequence, a positive effect was also noticed as regard litter health and performance characteristics in terms of: (1) decrease in piglet diarrhoea score, (ii) decrease in pre-weaning mortality thus leading to increase in the number of weaned piglets per litter and (iii) increase in piglet body weight at weaning. Moreover, BioPlus 2B tended to improve the health status and fertility of sows demonstrating: (i) tendency to a lower proportion of sows with Mastitis-Metritus-Agalactia (MMA) problems and (ii) lower proportion of sows returning to oestrus.
