摘要: 探讨牛乳铁蛋白(Bovine lactoferrin blF) 基因bLF第四外显子的多态性与乳房炎发生的关系.利用PCR-SSCP 技术,分析了bLF基因第四外显子的多态性在86 头中国西门塔尔牛中的基因型分布及其多态性与乳房炎的关系.经χ2 独立性检验,发现该多态片段3种基因型在健康牛中分布不一致(P<0.05),在患病牛中BB基因型频率较高,说明该多态性与乳房炎存在一定关系,可能是奶牛乳房炎的一个分子标记.

Abstract: This study is to investigate the association between Bovine Lactoferrin gene exon4 polymorphism and mastitis.In this experiment,the genotype distribution of polymorphism fragment in bLF gene exon4 was analyzed by PCR-SSCP in 86 Chinese Simmental cattles.Meanwhile,the effect of bLF gene exon4 on mastitis was analyzed.It showed that:the distribution of three genotypes was significantly different(P<0.05) of healthy dairy cows by using x2 analysis.The BB genotype frequency was higher in the bovine mastitis cases,which suggested that this polymorphism could be related to bovine mastitis affection and might become a molecularmarker of the mastitis.

Key words: Chinese Simmental Cattles, Bovine lactoferrin, Mastitis, Somatic cell count, PCR-SSCP
