- 确定关键的微生物生物标志物,与家禽中的特定表型相关.
主要方法:
- 16S rDNA测序对来自各种胃肠段的肠道内容进行了测序 (作物,腹腔,胃肠,阴,阴,阴,直肠).
- 测量包括体重,屠宰重量,肠道长度和相对肠道长度.
- 使用了统计分析,包括α和β多样性,随机森林和相关性分析.
主要成果:
- 与肉相比,的体重,屠宰重量和肠道长度显著更高,但相对肠道长度较低.
- 肉在大多数肠道部分表现出较低的微生物丰富性和多样性,其中Firmicutes占主导地位.
- 在和肉之间观察到不同的微生物社区结构,确定了与表型相关的微生物ASVs (Amplicon测序变种).
结论:
- 肠道微生物群的组成和多样性是禽类的物种特异性,与生长和肠道发育相关.

Anatomy of the Intestines
86.8K
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...

Background and Environment Affect Phenotype
7.4K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
