概括

日本黑色Wagyu牛的料效率与大理石等肉质特征有积极的相关性. 这表明剩余料摄入量 (RFI) 可以作为选择标准,而不会牺牲优质牛肉的特点.

科学领域:

动物科学动物科学
遗传学是一个遗传学.
食品科学食品科学食品科学

背景情况:

日本黑色Wagyu牛因其特殊的大理石和肉质而受到重视.
高昂的生产成本,特别是料进口,需要提高效率.
遗传选择在历史上优先考虑了大理石化,而不是料效率.

研究的目的:

为了研究料效率 (剩余料摄入量 - RFI) 和日本黑色Wagyu.肉质之间的表型关系.
为了确定同时对两个特征进行表型选择的可行性.

主要方法:

在39头Wagyu牛的900天肥期内,使用剩余料摄入量 (RFI) 评估料效率.
动物被食高粉饮食,缺乏维生素A,以增强大理石化.
分析了RFI和肉类质量参数 (坚度,大理石,整体评分) 之间的表型相关性.

主要成果:

在料效率和肉质特征之间观察到正相关性.
料效率更高的瓦古牛表现出优越的肉质坚硬度,大理石化和整体质量评级.
与最不高效的动物相比,十种最有效的料动物的粉率 (+ 13.2%) 和质量排名 (+ 12%) 显著增加.

结论:

通过RFI测量的料效率,与日本黑色Wagyu的理想肉质相表型相关.
在没有损害他们着名的肉质的情况下,选择在瓦古牛中改善RFI是可行的.
研究结果支持将RFI纳入基因选计划,以实现可持续和高质量的瓦古牛肉生产.

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...

Epistasis

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
