摘要: 旨在评估体细胞克隆技术(SCNT)在托佩克E系超级公猪快速扩群中的应用效果。本研究以12头超级公猪为供体,进行细胞分离培养、冻存和扩增传代培养出1 100个胚胎并移植至6头母猪,最终4头分娩29头仔猪(克隆效率2.63%),并对克隆猪与非克隆猪的生长发育、精液品质及所配母猪繁殖性能进行比较分析。结果,克隆猪与供体正常后代在生长发育上无显著差异,克隆猪在精液体积((188.17±49.27)mL)和有效精子数((486.35±159.56)亿)相较于供体同胞后代和供体半同胞无显著差异(P>0.05),配种后的母猪繁殖性能无明显差异,且SNP检测证明克隆猪与供体基因不一致率均在0.14%以下,表明遗传信息来源于供体。综上,克隆猪相较于供体后代繁殖性能和生长性能无明显差异,SCNT技术可有效用于超级公猪扩群生产。

Abstract: The study aimed to evaluate the application effect of somatic cell cloning technology (SCNT) in the rapid expansion of Topigs E line super boars. Using 12 super boars as donors, 1 100 embryos were isolated, cultured, frozen, amplified and subcultured, and transferred to 6 sows. Finally, 4 sows delivered 29 piglets (cloning efficiency 2.63%). The growth and develo-pment, semen quality and reproductive performance of cloned and non-cloned pigs were compared and analyzed. The results showed that there was no significant difference in growth and development between cloned pigs and donor normal offspring. There was no significant difference in semen volume ((188.17±49.27) mL) and effective sperm number ((486.35±159.56) million) between cloned pigs and donor siblings and donor half-sibs. There was no significant difference in reproductive performance of sows after mating. SNP detection showed that the inconsistency rate between cloned pigs and donor genes was below 0.14%, indicating that genetic information was derived from donors. In summary, there was no significant difference in reproductive performance and growth performance between cloned pigs and donor offspring. SCNT technology can be effectively used for super boar expansion production.

Key words: somatic cell cloning, breeding boars, expanding reproduction
