背景情况:

羊奶的营养价值受脂质组成的影响,受饮食和遗传学的影响.
了解DGAT1和SCD等关键基因的遗传变异对于优化牛奶质量至关重要.

研究的目的:

在Valle del Belìce羊群中调查DGAT1和SCD基因的遗传变异.
评估DGAT1基因型和食补充剂 (胡卜肉质与大麦谷物) 对牛奶质量和脂肪酸概况的影响.

主要方法:

对DGAT1和SCD基因进行基因定型,以识别多态性 (g.127 C > A和g.87 C > A).
基于DGAT1基因型和饮食的牛奶产量,成分 (包括尿素) 和脂肪酸概况的分析.
评估动脉动脉生成和动脉动脉生成指数.

主要成果:

DGAT1基因型影响了牛奶尿素含量和脂肪酸概况 (CA基因型中较高的短链脂肪酸,较低的多不和脂肪酸).
与大麦谷物相比,胡卜肉补充剂增加了牛奶脂肪含量,和脂肪酸和神经动脉生成/血栓生成指数.
没有观察到DGAT1基因型和饮食之间的显著相互作用.

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...
