中文摘要 | 本研究選擇在豬第 6號染色體連鎖圖譜約佔 166分摩根上的 10個微衛星遺傳標記,包括 MP35、 SW2406、SW2525、S0087、SW1129、SWC4、SW280、SW1881、SW322及 SW607,用以篩檢並分析 242頭種母豬之不同微衛星遺傳標記基因型,及其與母豬總產仔數、活仔數及仔豬存活率性狀之相關性。基因型檢測結果顯示,每個遺傳標記之交替基因分布皆有品種間的差異。以一般線性模式和最小平方平均法分析母豬個別遺傳標記交替基因與其產仔性能之相關性結果顯示,某些遺傳標記交替基因與三個品種母豬的產仔性能極顯著相關並具有正效應;其中,藍瑞斯母豬具 MP35B7與 SW1881B1者,其產仔性能顯著較佳;相同地, SW1129B1與約克夏母豬產仔性能有極顯著相關且具正效應;而與杜洛克母豬產仔性能有極顯著相關且具正效應的標記則有 MP35B5、SW2406B1及 SW1881B6。相反地,不同品種母豬具有某些交替基因,其產仔性能則會比未具有該交替基因者差。在本研究中,並未找到與盤克夏母豬產仔性能有極顯著相關且具正效應的標記交替基因。 |
英文摘要 | A total of ten microsatellite markers including MP35, SW2406, SW2525, S0087, SW1129, SWC4, SW280, SW1881, SW322, and SW607 spread on swine chromosome 6 (SSC6) were used to genotype 242 parous sows, including Landrace, Yorkshire, Duroc and Berkshire breeds. These markers spanned about 166 cM on the linkage map of SSC6. Three traits including total number born (TNB), number born alive (NBA), and the corresponding survivability of piglets were collected and analyzed in this study. The result indicated that there were significant breed effects in the distribution of allele frequencies for all markers analyzed. The relationship between litter performances described above and the presence of individual allele for parous sows in Landrace, Yorkshire and Duroc breeds were studied. Both positive and negative effects of alleles on sows’ performances were observed. The marker-allele groups, i.e. MP35B7 and SW1881B1, SW2406B1, and MP35B5, SW2406B1, and SW1881B6 were beneficial for Landrace, Yorkshire, and Duroc sows, respectively. However, alleles with negative effects on sows’ litter performances were also found. Furthermore, no specific marker allele was found to be significantly related to Berkshire sows in this study. |
