The aim of the current study was to search for genetic markers, microsatellite loci associated with laying performance in ostriches. The material consisted of two groups of ostrich hens characterized by high or low laying performance (over 75 and less than 25 eggs per season, respectively). The investigation covered 30 microsatellite loci characteristic for the ostrich (the CAU group) and led to identification of significant differences in allele and genotype frequencies between the two groups of hens considered. Out of a total of 30 microsatellite loci examined, 28 showed different alleles in relation to analyzed performance groups. In hens of high laying performance (HP group, n = 12), specific alleles occurred in 23 microsatellite loci (40 alleles of 243 identified), while in those of low egg production (LP group, n = 12), they occurred in 22 (51 alleles of 243 identified). The results indicate the usefulness of the microsatellite loci as the potential genetic markers associated with laying performance that can be applied for genetic improvement of ostrich flocks.
本研究旨在寻找与鸵鸟产蛋性能相关的遗传标记和微卫星位点。材料由两组具有不同产蛋性能（分别为每季节产蛋 75 枚以上和 25 枚以下）的鸵鸟母鸡组成。该研究涵盖了 30 个具有鸵鸟特征的微卫星位点（CAU 组），并确定了两组母鸡在等位基因和基因型频率方面存在显著差异。在所检查的 30 个微卫星位点中，28 个与分析的性能组存在不同的等位基因。在产蛋性能高的母鸡（HP 组，n=12）中，23 个微卫星位点出现了特定的等位基因（在鉴定的 243 个等位基因中，有 40 个），而在产蛋性能低的母鸡（LP 组，n=12）中，22 个微卫星位点出现了特定的等位基因（在鉴定的 243 个等位基因中，有 51 个）。这些结果表明，微卫星位点可用作与产蛋性能相关的潜在遗传标记，可应用于鸵鸟群体的遗传改良。
