概括

基因型显著影响蛋质量特征,而不是波兰本土母的产卵时间. 产卵时间会影响蛋的重量,的毛孔和pH值,但不会影响lyszyme的水平.

科学领域:

动物科学动物科学
家禽遗传学家禽遗传学
食品科学食品科学食品科学

背景情况:

卵子质量和酶受各种因素的影响.
在遗传保护计划中对品种的研究正在出现.
了解这些因素对于保护遗传资源至关重要.

研究的目的:

为了确定产卵时间和基因型对蛋质量的影响.
评估波兰本土母品种的白蛋白中溶酶含量和活性.
为了研究蛋质量特征和lyszyme之间的相关性.

主要方法:

从四个波兰本土品种 (绿腿,黄腿,罗德岛红,莱戈恩) 的蛋在7点和13点收集.
评估了蛋质量参数 (体重,白膜高度,贝毛孔,pH值) 和溶酶含量/活性.
进行了统计分析,以确定显著的影响和相关性.

主要成果:

产卵时间影响了卵子的重量,白膜的重量,的孔密度和pH值.
没有观察到产卵时间对白溶酶含量或活性有显著影响.
基因型对卵子质量特征的影响比产卵时间更大.
在蛋特征和白膜高度之间,以及在霍格单位和lyszyme之间发现了负相关性.

结论:

在这些本地品种中,基因型比产卵时间更重要地决定了卵子质量.
产卵时间会影响特定的卵子物理特性,但不会影响lyszyme的保护性质.
进一步的研究可以为这些宝贵的家禽遗传资源的保护策略提供信息.

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...
