AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve efficient early identification of immune traits in Xiangxiong semi-fine wool sheep. Traditional disease-resistant breeding relies on recording after an individual becomes ill, which is costly and has limited accuracy, thus restricting breeding progress.

Method used

A molecular marker is provided, located at the 102,308,292nd base on chromosome 2 of the Lamb reference genome ARS-UI_Ramb_v3.0. By detecting the genotype at this locus, the levels of immunoglobulins IgA, IgG, and IgM in lambs can be predicted, enabling early breeding selection.

Benefits of technology

By detecting this SNP molecular marker, the immune capacity of adult sheep can be accurately predicted at the lamb stage, providing an early selection method, improving breeding efficiency, reducing drug use, and cultivating new breeds with inherently strong physiques.

Abstract

本发明涉及分子标记技术领域,尤其涉及一种象雄半细毛羊免疫性状早期鉴定的分子标记及其应用。本发明首次发现了第2号染色体上第102308292位点的基因型与象雄半细毛羊的免疫球蛋白(IgA,IgG,IgM)水平存在确定性关联。本发明通过检测该位点基因型,即可在羔羊阶段预测其未来的体液免疫能力,从而实现早期选种。这为象雄半细毛羊的抗病育种提供了一个用于非诊断目的的强效SNP标记。
