动物科学动物科学
禽类营养养禽类营养
料加工技术料加工技术

背景情况:

料成本占家禽生产成本的很大一部分.
优化料加工对于提高肉养殖场效率至关重要.

研究的目的:

为了研究不同磨机速度 (HMS) 对肉性能的影响.
评估对颗粒质量,胃肠形态和与生长相关的基因表达的影响.

主要方法:

1,500只肉被分配到三个HMS组 (100%,75%,50%) 进行28天.
评估了生长性能,颗粒特征,胃肠形态和基因表达 (GH,GHR,IGF1,IGF2).

主要成果:

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...
