Ovulation and embryo recovery rates following immunization of mares against an inhibin alpha-subunit fragment



Ovulation and embryo recovery rates following immunization of mares against an inhibin alpha-subunit fragment



Theriogenology. 38(5): 823-831



Six normally cycling mares were immunized 5 times at 3-week intervals with a synthetic porcine inhibin alpha-subunit fragment which had been conjugated to bovine serum albumin and emulsified in Freund's incomplete adjuvant. Immunized mares ovulated a significantly larger (P lt 0.01) number of follicles per estrous cycle (2.8 +- 1.1; range 1 to 8 ovulations) than 14 nonimmunized control mares (1.1 +- 0.1; range 1 to 2 ovulations). Day-7 embryo recovery rates tended to be higher (P lt 0.1) in immunized mares (1.6 +- 0.5 embryos per flush) than in control mares (0.7 +- 0.2 embryos per flush). No differences in interovulatory intervals were found between the 2 groups. These results indicate that immunization against inhibin may be useful in inducing development and ovulation of multiple follicles for embryo transfer in the mare.
