概括

在胡羊群中,食D-ribose补充剂没有改变或便微生物多样性或代谢功能. 然而,它确实改变了在小肠和便中特定细菌属的相对丰富程度.

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:

排骨微生物组在反动物的消化和健康中起着至关重要的作用.
了解像D-ribose这样的料添加剂对肠道微生物群的影响对于优化动物生产至关重要.

研究的目的:

调查食中补充D-ribose对胡羊的微生物多样性,群体组成和和便微生物群的代谢功能的影响.

主要方法:

黄羊被随机分为对照组和D-ribose补充组 (300 mg/kg-1).
使用高通量测序,分析了和便样本的微生物多样性,组成和代谢功能.
使用非度量多维缩放 (NMDS) 和相似性分析 (ANOSIM) 来评估微生物社区的差异.

主要成果:

补充D-ribose并没有显著影响小肠或便中的微生物丰富性,多样性或均性.
特定细菌属的丰度发生了变化:蓝藻细菌减少,而Herbivorax和Faecalibacterium在体中增加.
便微生物群显示Verrucomicrobia,Candidatus Saccharibacteria,Bifidobacterium和Caproiciproducens的相对丰度下降,而Lawsonibacter和Massilioclostridium的相对丰度增加.
虽然肠微生物群在两组之间没有显著差异,但便微生物群组成在对照组和D-ribose组之间有显著差异 (ANOSIM,R = 0.203,p = 0.017).
在或便微生物群中没有观察到对代谢功能的显著影响,相对丰度大于1%.

结论:

胡羊的食中补充的D-ribose并不会影响和便中的整体微生物多样性或代谢功能.
补充D-ribose可以选择性地改变体和便微生物群中的特定细菌属的相对丰度.
这些发现表明,D-ribose可能会调节肠道细菌组成,但不会大大影响杂动物中的微生物生态系统稳定性或功能.

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Overview of Metabolism

Overview of Metabolism

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
