【摘要】：水牛是全球第二大产奶家畜,水牛奶虽然营养丰富,但目前产奶水平较低,缺乏专门化乳用品种。利用分子育种手段,对产奶性状进行遗传改良,培育专门化乳用品种,是水牛育种的重中之重。目前主要有2种策略应用于水牛产奶性状的改良,一种是候选基因策略,与水牛产奶性状相关的候选基因主要包括STAT1、A2M、GHRL、DGAT1、STAT5A、BTN、OXT、LEP、TG、MTNR1A和CSN1S1等,另一种是全基因组选择策略,虽然该技术在奶牛上应用广泛,但目前在水牛研究中刚刚起步,继续开展对水牛产奶性状分子标记的筛选与应用,可为提高水牛产奶性能、建立专门化乳用品系提供技术支撑,对于水牛良种化培育具有重要的现实意义。
[Abstract]:Buffalo is the second largest dairy animal in the world. Although buffalo is rich in nutrition, it has a low milk production level and lacks specialized milk products. It is the most important point of buffalo breeding to use molecular breeding methods to improve the milk-producing traits and to cultivate specialized dairy products. At present, there are mainly two strategies applied to the improvement of buffalo milk production traits. One is the candidate gene strategy. The candidate genes related to buffalo milk production traits mainly include STAT1A2MU GHRLGHRLGHRLGHRL5, BTNOXTOXTGG, TGG, MTNR1A and CSN1S1, and the other is the whole genome selection strategy. Although this technique has been widely used in dairy cattle, it has just started in the research of buffalo. The screening and application of molecular markers for buffalo milk production traits can provide technical support for improving buffalo milk production performance and establishing specialized dairy product lines. It has important practical significance for buffalo breeding.
