概括
牛的延长反时间与通过肠道微生物组变化减少肠道甲排放 (EME) 有关. 这项研究确定了反时间作为选择低EME牛的非侵入性工具,促进气候智能农业.
科学领域:
- 动物科学动物科学
- 环境科学 环境科学
- 微生物学 微生物学
背景情况:
- 畜牧业的肠道甲排放 (EME) 对环境可持续性和动物生产效率产生负面影响.
- 化时间 (RT) 是一种与甲产量相关的潜在表型,可能由肠道微生物群介导.
研究的目的:
- 调查反时间 (RT),肠道微生物群和肠道甲排放 (EME) 之间的联系.
- 确定选择低EME奶牛的非侵入性代理方法.
主要方法:
- 使用了反肉,便和肠微生物组分析.
- 在高RT与低RT奶牛中量化了EME并分析了微生物和代谢概况.
主要成果:

What is Monogastric Digestion?
69.6K
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.

Bacterial Flora of the Large Intestine
359
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.
