概括
蛋的高透光度会对肉的化成功产生负面影响,但它与特异重力或贝颜色无关. 半透明性会影响卵子的体重减轻,化能力和胚胎死亡率,而高度半透明的卵子表现最差.
科学领域:
- 禽畜科学 禽畜科学 禽畜科学
- 动物育种 动物育种
- 化能力研究 化能力研究
背景情况:
- 蛋质量对于 brojiler 化能力至关重要.
- 蛋的半透明性与贝层的混乱有关,但它对化及其与特定重力 (SG) 或贝颜色的关系的影响还未得到充分研究.
研究的目的:
- 调查蛋半透明度,比重 (SG) 和贝颜色之间的关联和相互作用.
- 评估这些特征对卵子化参数的影响,包括体重减轻,化能力和胚胎死亡率.
主要方法:
- 从15976只肉养殖蛋 (Ross 308AP, 51 wk) 中选择了1138只蛋,分为5个SG类别和浅色/深色.
- 将蛋分为3个半透明度得分,并将它们化以评估化参数.
- 分析了透光度,SG和颜色之间对减肥,化能力和胚胎死亡率的相互作用的数据.
主要成果:
- 对于化参数,没有发现蛋半透明度和SG或颜色之间的相互作用.
- 蛋的半透明度显著影响了蛋的体重减轻,化能力和胚胎死亡率;高度半透明的蛋显示出较差的结果.
- 较低的SG (<1.070) 与增加的体重损失,减少化能力和更高的污染相关.
- 轻蛋的晚期胚胎死亡率较高,而SG和颜色对整体化能力没有影响.
结论:
- 蛋的半透明度是影响蛋表现的重要因素,独立于特异重力和贝颜色.
- 特定重力是卵子减肥,化能力和污染的重要预测因素.
- 贝颜色影响晚期胚胎死亡率,但不是整体化能力或体重减轻.

02:27Background and Environment Affect Phenotype
6.5K
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...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

01:11Testing a Claim about Mean: Known Population SD
2.7K
A complete procedure of testing the hypothesis about a population mean is explained here.
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
