| 摘要: |
| 为研究家畜育种值估计方法的原理和适应性，提高家畜育种值估计的准确性。以“家畜”、“育种值估计”、“方差组分”、“基因组选择方法”和“统计模型”为关键词，利用中国知网、百度学术、谷歌学术和SCI-HUB对2010—2019年的家畜育种值估计方法进行文献检索和归纳。研究发现不同家畜遗传评估方法所适合的研究对象不同，并且在研究过程中所选用的方法不同对育种值估计得出的结果的准确性也不相同，因此在应用家畜育种值估计时，应充分了解各种方法的原理并选择合适的估计方法，以提高家畜育种值估计的准确性。未来遗传评估模型的建立应以研究对象为目标，选择合适的遗传评估模型，以期获得更加准确的估计育种值进行早期选种，缩短世代间隔，加快遗传进展。 |

| Abstract: |
| To study the principle and adaptability of the estimation methods of breeding value for livestock and improve the accuracy of breeding value estimation, literatures related to the methods of estimating breeding value published from 2010 to 2019 are searched by using “livestock”, “estimation of breeding value”, “variance component”, “genome selection method” and “statistical model” as keywords. China National Knowledge Infrastructure, Baidu Scholar, Google Scholar and SCI-HUB are taken as data sources. It is found that different methods are suitable for different research objects, and the accuracy of estimation breeding value is different in different methods. Therefore, to estimate breeding value for livestock and improve the accuracy of estimation of breeding value of livestock, the principles of various methods and choose appropriate estimation methods should be fully considered. More accurate estimations of breeding values could be achieved by establishing genetic evaluation model for study and select suitable genetic evaluation model to assist early selection, shorten the generation interval and speed up the genetic progress in future. |
