概括

热应激会对的食欲和肠道健康产生负面影响,但矮 (DFC) 由于其独特的特征而表现出弹性. 这些发现突出了DFC的发现.

科学领域:

动物科学动物科学
身体生理学身体生理学
遗传学是一个遗传学.

背景情况:

没有汗腺,对热应激 (HS) 很敏感.
开发出了一种具有毛羽毛 (DFC) 的小矮品种.
了解HS对DFC的影响对于家禽生产至关重要.

研究的目的:

评估HS对DFC生长,屠宰性能和组织完整性的影响.
在HS下分析与肌肉发育,食欲和肠道运输相关的基因表达变化.
确定数学模型适用于DFC增长分析的适用性.

主要方法:

使用三个数学模型进行增长分析 (Gompertz模型被选中).
在34°C下每天暴露8小时,持续2周.
屠宰性能,组织形态学和基因mRNA表达的评估 (qPCR,西部Blot,组织截图).

主要成果:

HS影响了肌肉,肝脏,脏和小肠的完整性;大肠的长度下降.
肌肉发育因子MYOD1下调,MSTN上调;阴VH/CD减少.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

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...
