Large genetic improvements in the quantitative traits of growth, production, and efficiency of farmed livestock have been made over recent decades, and by introduction of genomic technology these are being enhanced. Such continued improvement requires that there be available variation to utilize. The evidence is that little variation has been lost and such rates are indeed sustainable in the future.
近几十年来,养殖家畜在生长、生产和效率等数量性状方面取得了巨大的遗传进展,并且通过引入基因组技术,这些进展正在得到加强。这种持续的改进需要有可用的变异来利用。有证据表明几乎没有变异丢失,而且这样的速率在未来确实是可持续的。
