- 生殖生物学 生殖生物学
背景情况:
- 播种垃圾的表现对猪生产经济至关重要.
- 同等性显著影响种子的生产力.
- 肠道微生物群的改变与动物的表现特征有关.
研究的目的:
- 调查母猪平价,肠道微生物群组成和垃圾表现之间的关系.
- 确定与老母猪产量下降相关的特定微生物变化.
主要方法:
- 对来自大白母猪的1363个子表现记录的分析.
- 16S rRNA扩增子测序来自263头母猪的便DNA,跨越不同的平价.
- 较年轻的母猪 (平价1-6) 和较老的母猪 (平价7+) 之间的肠道微生物群多样性和组成的比较.
主要成果:
- 7或更高平价的母猪在总出生数 (TNB) 和健康出生数 (NBH) 中显著下降.
- 与年轻母猪相比,老母猪的肠道微生物α多样性下降.
- 在年长的母猪中观察到病原细菌 (例如,肠杆菌,链球菌) 的比例增加,SCFA产生细菌 (例如,鲁米诺可可菌) 的比例减少.
结论:
- 肠道微生物群失调,以减少多样性和增加病原性为特征,与母猪的高级平价相关.

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

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.
