Immunological aspects of infertility in cows and buffaloes in Egypt

ABSTRACT

The present investigation revealed that the immunological reaction between the cervical mucus of repeat breeder cow and washedl spermatozoa gave a higher titre. On the other hand the reaction of the cervical mucus of normal cow and buffalo-cow with the seminal plasma gave a low agglutinating titre. The influence of the cervical mucus of repeat breeder cow- and buffalo-cow on the homologus bull semen gave a higher reaction than that with the heterologous bull semen. The results were attributed to the presence of agglutinating and immobilizing antibodies against the semen in the cervical mucus of the repeat breeder cows and buffalo-cows
