A healthy microbial community in the gut of piglets is critical to minimize the negative performance consequences associated with dietary and environmental changes that occur at weaning. Tonisity Px, an isotonic protein drink, is a potential alternative to balance the gut microbiota as it contains key ingredients for nourishing the small intestine. In the present study, 16 litters comprising 161 piglets were randomly allocated to a group to which Tonisity Px was provided from days 2 to 8 of age (TPX group) or to a control group, to which no Tonisity Px was provided. The TPX group also received Tonisity Px in the 3 days before and after weaning. At days 9, 17, and 30 of age, fecal and ileum samples were collected from piglets belonging to both groups and analyzed using gene sequencing, semiquantitative PCR of serogroups, and semiquantitative culture. Overall, Tonisity Px increased the abundance of beneficial bacterial populations ( and species) and reduced potentially pathogenic bacterial populations ( and ), in both the pre-weaning and post-weaning periods.
仔猪肠道中的健康微生物群落对于将断奶时饮食和环境变化带来的负面生产性能影响降至最低至关重要。等渗蛋白饮料Tonisity Px是平衡肠道微生物群的一种潜在替代品，因为它含有滋养小肠的关键成分。在本研究中，将16窝共161头仔猪随机分为两组，一组在2至8日龄期间提供Tonisity Px（TPX组），另一组为对照组，不提供Tonisity Px。TPX组在断奶前3天和断奶后3天也接受Tonisity Px。在9日龄、17日龄和30日龄时，从两组仔猪中采集粪便和回肠样本，并使用基因测序、血清群半定量PCR和半定量培养进行分析。总体而言，在断奶前和断奶后阶段，Tonisity Px均增加了有益细菌种群（和物种）的丰度，并减少了潜在致病细菌种群（和）。
