Native chickens are important both economically and for the preservation of genetic diversity, especially for optimizing the reproductive performance of male chickens, which plays an important role in genetic propagation. However, hot and humid weather affects the quality of semen and the breeding ability of male chickens. One method used to solve this problem is genetic selection using genomic technology, which improves accuracy and shortens the breed selection time. Therefore, we collected and analyzed data from relevant research to review the genetic improvement approach for male chickens using genomic technology. We compared popular genomic selection models, such as GBLUP, ssGBLUP, Bayesian approaches, RR-GBLUP, WGBLUP, and MTGBLUP, as well as genome-wide association studies (GWASs), to identify genes associated with semen quality and heat tolerance. The results of this analysis suggested that the use of genomic data can enhance genetic selection and enable breeding to occur more quickly and accurately. We addressed the trends and scientific developments in male chicken genetic selection, together with the benefits and constraints of each method. This will help breeders and researchers to create the most successful genetic selection plans for the next generation of chickens.
土鸡在经济上以及保护遗传多样性方面都很重要，特别是对于优化雄性鸡的繁殖性能而言，这在遗传传播中起着重要作用。然而，炎热潮湿的天气会影响精液质量和雄性鸡的繁殖能力。解决这个问题的一种方法是使用基因组技术进行遗传选择，这提高了准确性并缩短了品种选择时间。因此，我们收集并分析了相关研究的数据，以回顾使用基因组技术对雄性鸡进行遗传改良的方法。我们比较了流行的基因组选择模型，如GBLUP、ssGBLUP、贝叶斯方法、RR-GBLUP、WGBLUP和MTGBLUP，以及全基因组关联研究（GWAS），以确定与精液质量和耐热性相关的基因。该分析结果表明，使用基因组数据可以加强遗传选择，并使育种能够更快、更准确地进行。我们阐述了雄性鸡遗传选择的趋势和科学进展，以及每种方法的优点和局限性。这将有助于育种者和研究人员为下一代鸡制定最成功的遗传选择计划。
