| 摘 要： | 目的]为探讨奶牛产奶量与红细胞钾含量和S441遗传标记是否存在联系.方法]本研究以6～8月产奶量为依据将奶牛分为高产耐热组、中产组和低产不耐热组,采用原子吸收分光光度法测定红细胞钾含量,采用SCAR技术对S441遗传标记进行检测.结果]表明:高产耐热组奶牛红细胞钾含量最低,90%有S441标记;中产组奶牛红细胞钾含量居中,40%有S441标记,低产不耐热组奶牛红细胞钾含量最高,10%有S441标记.结论]初步得出奶牛耐热性能与红细胞钾含量呈一定的负相关,与S441遗传标记的有无存在正相关趋势.

| Abstract: | In order to explore whether there were some relationship among cows' milk yield in Summer,potassium content in erythrocytes and S441 genetic marker,the cows were divided into high yield with heat resistance group,moderate yield group and low yield without heat resistance group according to milk yield during June to August.Potassium content in erythrocytes was determined by atomic absorption spectrophotometry,S441 genetic marker was detected by SCAR.The results showed that: The potassium content in erythrocy... |
