科学领域:
- 动物科学动物科学
- 微生物学 微生物学
- 营养科学 营养科学
背景情况:
- 植物化学物质可以调节乳头功能和发酵.
- 研究人员评估了山羊的饮食,补充了素或草药混合物 (生,大,Artemisia,黄).
- 这项研究调查了对乳头发酵,微生物群和组织组织学的影响.
研究的目的:
- 评估凝结素和特定草药混合物对山羊的乳头发酵和微生物群落的影响.
- 为了分析补充剂后皮组织的组织学变化.
- 确定这些补充剂在改善功能方面的潜力.
主要方法:
- 18只沙米山羊被分为三个组:对照组,添加素 (T) 的组和添加草药混合物 (HM) 的组.
- 羊的基本饮食是草干草和缩料.
- 分析了皮的pH值,挥发性脂肪酸 (VFA),微生物群体组成 (使用PCoA) 和皮组织学.
主要成果:
- 草药混合物 (HM) 组表现出更高的乳头pH值,总VFA和特定VFA度 (乙,,黄油等). ) 的情况.
- 补充剂改变了微生物种群,增加了Bacteroidota和Proteobacteria,同时减少了Firmicutes和Fibrobacterota.

71.2K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.
