title: Effect of antibodies to boar spermatozoa on fertility in sows and rabbits.
abstract: Immunization of sows with boar spermatozoa had no effect on the sows' fertility or on the number of liveborn young from the first pregnancy. An effect was not recorded until the second pregnancy, when the number of stillborn young increased. The total number of young in the litters was not reduced. Pig and rabbit antibodies to boar spermatozoa had no negative effect on the fertilizing capacity of rabbit spermatozoa. The intravenous administration of antibodies against boar spermatozoa to inseminated female rabbits did not affect their fertility. If the antibodies were injected intramuscularly 7 days before and 10 days after insemination, degenerating fetuses were found in the uterus of inseminated female rabbits. After immunizing sows with boar spermatozoa, specific cellular immune reaction was not demonstrated.
