BookPublisher: 1994Subject(s): Department of TheriogenologyDDC classification: 0383,T Dissertation note: The present study was designed with the assumption that high titres of antisperm antibodies in repeat breeders might be a contributing factor for conception failure in such animals. For this purpose, 32 buffaloes/buffalo heifers were divided into four equal groups. From the normal cyclic and repeat breeder buffaloes, 48 serum samples were collected at 0, 1, and 24 hours after insemination, respectively. Oestrus mucus was also collected from these animals. A total of 16 serum samples were collected from virgin heifers and pregnant buffaloes. The serum and mucus samples were subjected to simple agglutination test, sperm quantitative penetration test and sperm cervical mucus contact test. High antibody titres were recorded in the serum and oestrus mucus of repeat breeders. Moreover, it was observed that lesser number of spermatozoa penetrated through a definite distance in cervical mucus of repeat breeder buffaloes as compared to cervical mucus of normal cyclic animals. Similarly higher number of spermatozoa exhibited shaking movement over a period of time in cervical mucus of repeat breeders, which indicates the presence of spermagglutinins.
Thus, it can be concluded that antisperm antibodies may be responsible for conception failure in repeat breeder buffaloes.
