抽象的。共有115只动物代表5个遗传组：3只纯种Booroola美利奴、Corriedale和Olkuska，以及2只Booroola杂交犬被纳入研究。微卫星OarAE 101在97 ~ 119 bp范围内共检测到6个等位基因，BM 1329在162 ~ 174 bp范围内共检测到5个等位基因。FecB基因存在的标记似乎是微卫星OarAE 101的情况下的97 bp和BM 1329的情况下的162 bp的等位基因。FecB携带者（Booroola-Corriedale）和非携带者（Corriedale）的初生重、100日龄断奶重（双胞胎中的公母）以及28日龄和100日龄的增重均存在显著差异，纯种羔羊的各项指标均高于非携带者。
Abstract. Altogether 115 animals representing 5 genetic groups: 3 purebred Booroola Merino, Corriedale and Olkuska, and 2 Booroola crossbreds were included in the studies. In total 6 alleles from 97 bp to 119 bp in microsatellite OarAE101, and 5 alleles from 162 bp to 174 bp in BM1329 were identified. The marker of FecB gene presence seems to be an allele of 97 bp in the case of microsatellite OarAE 101 and 162 bp in the case of BM1329. Significant differences FecB carriers (Booroola-Corriedale) and non-carriers (Corriedale) in birth weight and at weaning at 100 days (males and females from twins) as well as weight gain during the first 28 days and 100 days were found. Purebred lambs showed higher values of the investigated traits.
