疾病基因研究取得进展

     CANADA - Investment in swine health research and specifically in the genetics of swine diseases has increased substantially in the last several years, writes Bob Kemp, PhD PAg, Vice President Genetic Programs and R&D, Genesus Inc.

     The increasing availability of genomic tools allows for a much more detailed analysis of genetic influences on a pigs response to a disease challenge. The most difficult part of this research is collecting disease “phenotypes” which are generally associated with responses of pigs that are undergoing a disease challenge. Fortunately a few groups have collaborated to fund and supply pigs and facilities where these phenotypes can be collected. Early research has pointed to some aspect of genetic control to a pig’s response to a disease challenge. The issue has been to refine the understanding of genetic control and then to determine how best to implement selection.    

　　加拿大——在过去几年中，关于猪健康及专门对猪疾病的遗传学研究的投资大幅度增加，PAg博士鲍勃•坎普写道(Bob Kemp)，他是加裕公司(Genesus Inc.)遗传项目和研发副总裁。

　　日益普及的基因组工具要求对影响猪的遗传因素进行更详细的分析，以应对疾病的挑战。这项研究最困难的部分是收集疾病“显型”，通常与正在接受疾病的挑战的猪的表现相关。幸运的是一些团体已经合作，投资及提供可以收集这些显型的猪和设施。早期的研究已经指出，基因的某些方面控制着猪应对疾病挑战的表现。这个问题已经重新定义为被基因控制，然后决定如何最好地实现选择。
