概括
肠道溶液 (IPS) 补充剂显著改善了小猪的生长,肠道发育和免疫功能. 这种增强的弹性支持小猪在关键的断奶阶段,并促进整体健康.
科学领域:
- 动物科学
- 胃肠病学
- 免疫学
背景情况:
- 哺乳对小猪的肠道发育和肠道健康至关重要,改善了断奶和随后生长的弹性.
- 含有Na+/K+离子,乳清蛋白和葡萄糖的肠溶液 (IPS) 对动物生长和肠道健康产生积极影响.
研究的目的:
- 评估IPS消费对哺乳猪的生长性能,免疫力,肠道发育和肠道微生物群的影响.
主要方法:
- 160只新生猪被分为对照组和IPS组.
- 从出生后的第2至第8天,直到断奶前的第3天,患者接受了IPS.
- 评估了生长参数,内形态,血免疫标记,内SIgA,紧结蛋白表达,Toll-like通路基因表达和肠道微生物组合.
主要成果:
- IPS 增加了 3. 6% 的体重,体重增加了 15. 7% (16-24 天).
- 增强膜高度和膜高度与密室深度的比率.
- 血IgA和IgM的升高,BUN的降低,阴SIgA的升高,紧结蛋白的升高 (GLP-2,ZO-1,Claudin-1),以及Toll-like通路基因的降低 (MyD88,TLR-4).
- 改变了肠道微生物群,增加了有益的细菌,
结论:
- IPS补充剂有效地提高了猪的体重,生长性能,免疫功能和肠道发育.
- IPS支持将其纳入断奶前小猪管理策略,以改善健康和弹性.

Probiotics
296
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

Development of Human Microbiota
61
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...
