2002年，斯洛文尼亚山区的几头奇卡牛被发现逃脱了官方的杂交政策。在这里，我们报告了一个基因特征，以评估他们作为本土品种的地位。我们比较了150头奇卡牛的14个微卫星标记的基因分型，并与16个中欧品种的数据进行了比较。我们发现，契卡牛和其他东阿尔卑斯山品种在遗传上一样多样化，比奥地利的西门塔尔牛更多样化，但比巴尔干的布沙牛更少。结构分析表明，Pinzguer混合体存在于几个个体中，但也表明了Cika的独特遗传身份。根据微卫星小组的评估，这项分析还可以挑选出基因纯度最高的Cika个体。这些原始的奇卡牛与平兹戈尔牛和普斯特塔勒牛一起形成了一个东部阿尔卑斯山品种群。Cika牛应被视为一种真正和有价值的遗传资源，这为边缘和山区的可持续农业和景观保护提供了明确的机会。
In 2002, it was discovered that several Cika cattle in the mountain areas of Slovenia had escaped the official policy of cross-breeding. Here, we report a genetic characterization to assess their status as autochthonous breed. We compared genotypes for 14 microsatellite markers in 150 Cika cattle individuals with data from 16 Central European cattle breeds. We show that Cika cattle are genetically as diverse as other Eastern Alpine breeds, are more diverse than Austrian Simmental but less than the Balkan Busha cattle. STRUCTURE analysis showed Pinzgauer admixture in several individuals but also indicated a unique genetic identity for Cika. This analysis also allowed a selection of the most genetically pure Cika individuals as assessed by the panel of microsatellites. These original Cika cattle form an Eastern Alpine breed cluster together with Pinzgauer and Pustertaler cattle. Cika cattle should be considered as an authentic and valuable genetic resource, which offers clear opportunities for sustainable agriculture and landscape conservation in marginal and mountain areas.
