摘 要：
本研究采用PCR-RFLP法对莱芜黑猪FUTⅠ基因M307位点多态性及其与生长性能的关系进行分析。结果表明:莱芜黑猪FUTⅠ基因M307位点均存在丰富的多态性,而且在该突变位点显著偏离Hardy-Weinberg平衡状态(P<0.01)。3种基因型对莱芜黑猪的初生重、断奶重和70日龄保育重(和断奶仔猪腹泻和水肿病密切相关)等均无显著影响(P>0.05)。本研究结果提示:肠毒素大肠杆菌F18抗性基因有可能起源于西方猪种,对莱芜黑猪无显著影响,有必要对其中所具备的遗传抗性做更深入的研究,寻找、定位其相应的QTL和抗性基因。

摘 要：
In this study,the polymorphisms at M307 of FUTⅠ gene in Laiwu Black pigs were investigated by the way of PCR-RFLP and their associations with growth performance were analyzed.The result showed that there were polymorphism at M307 of FUTⅠgene in Laiwu pigs,and the population was not in a state of Hardy-Weinberg equilibrium(P<0.01).The three genotypes had no significant effect on weight of birth,weight at weaning day and weight at day 70 th to Laiwu pigs(P>0.05).It was inferred that the resistance gene to ETEC F18 might be originated from western pig breeds,and the gene play an significant effect to the western pigs and had no effect to Laiwu Black pigs.Further study should be validated to identify and characterize putative QTL and functional gene responsible for the resistance to ETEC F18 in Laiwu Black pigs.
