Sows fertility after oxytocin addition in semen dose or vulvar injection to stimulate myometrial activity around insemination

These study compares farrowing rate and litter size in sows after oxytocin addition in sperm or after vulvar injection immediately before AI. Within firs 7 days after weaning, the total of 150 sows were AI: (a) with sperm doses additioned by 10 IU oxytocine immediately before AI (n=50), (b) after 5...

Summary:These study compares farrowing rate and litter size in sows after oxytocin addition in sperm or after vulvar injection immediately before AI. Within firs 7 days after weaning, the total of 150 sows were AI: (a) with sperm doses additioned by 10 IU oxytocine immediately before AI (n=50), (b) after 5 IU vulvar injection prior to AI (n=50), or (c) not treated, control, (n=50). Farrowing rate were significant higher (P<0.05) after vulvar oxytocin injection (88%) or oxytocin addition in AI dose (92%), compared with control sows (78%). These value were not significant differ (P>0.05) after vulvar oxytocin injection or oxytocin addition in AI dose. Treatment with oxytocin has no significant effect on litter size. These results indicate that oxytocin treatment can be useful method to improve sows fertility.
