This study investigated the efficacy of using probiotics on the performance and health parameters of sows and their litters. A randomized block design was used with 584 sows and 292 replications, with two dietary treatments: the control group (basal diet without probiotics) and the probiotic group (basal diet supplemented with 400 g/ton of a probiotic composed of () 541 and () 516). Feed intake was evaluated throughout the experimental period. Bodyweight and backfat thickness of the sows were measured at the beginning and end of each phase. Piglets were weighed individually at birth and at weaning. Performance variables and physiological parameters were analyzed. Sows that received the probiotic supplement exhibited increased milk production ( = 0.05) and bodyweight loss, along with reduced postpartum cortisol levels ( < 0.05). The piglets from the probiotic treatment group had higher ( < 0.001) weaning weight and fewer ( < 0.05) crushing deaths, received fewer ( < 0.001) medications, and had lower ( < 0.05) excretion of pathogenic bacteria and lower ( < 0.05) excretion of fecal sp. They also had higher ( < 0.05) concentration of fecal myeloperoxidase (MPO) close to weaning and improved ileal histomorphometric measures. In conclusion, supplementation with the probiotic product improves performance and promotes health parameters of the sows their litters.
本研究调查了使用益生菌对母猪及其仔猪的生产性能和健康参数的影响。采用随机区组设计，有584头母猪和292个重复，设置两种日粮处理：对照组（不添加益生菌的基础日粮）和益生菌组（基础日粮中添加400克/吨由()541和()516组成的益生菌）。在整个实验期评估采食量。在每个阶段开始和结束时测量母猪的体重和背膘厚度。仔猪在出生时和断奶时分别称重。分析生产性能变量和生理参数。接受益生菌补充剂的母猪产奶量增加（=0.05）且体重减轻，同时产后皮质醇水平降低（<0.05）。益生菌处理组的仔猪断奶体重更高（<0.001），压死死亡的仔猪更少（<0.05），用药次数更少（<0.001），病原菌排泄量更低（<0.05），粪便sp.排泄量更低（<0.05）。在接近断奶时，它们的粪便髓过氧化物酶（MPO）浓度也更高（<0.05），回肠组织形态计量学指标得到改善。总之，补充益生菌产品可提高母猪及其仔猪的生产性能并促进其健康参数。
