| 摘 要： | 繁殖效率是现代成功猪业生产体系母系性能评定指数。全基因组选育法,结合传统的数量性状位点基因选择(QTL)的遗传改进进展使得遗传优势能有益于最好种用性能的生产效率。一个优秀的种用母种群是从一个好的后备母猪生长发育方案开始的,基于这个方案有3个重要基础。他们是遗传基础、生理基础和营养基础。该文将讨论它们在现代种用猪群的繁殖效率改进中的作用,重点是集中在后备母猪。

| Abstract: | The reproductive efficiency is the maternal index of modern successful swine production system.Genetic improvement of genome-wide breeding combined with traditional quantative trait loci(QTL) selection makes genetic dominance benefit for production efficiency of best genetics.An excellent female breed population starts with a good growth program of replacement gilt,there are three important basis based on the program including genetic,physiological and nutritional basis.This paper aimed to discuss their improvement function in reproductive efficiency of modern breeding swine,especially in replacement gilts. |
