FSH is an important component of superovulations programs in the cow, its administration being made routinely intramusculary, at 12 hours intervals for 4 days. The aim of the study was to evaluate the efficacity of singledose FSH administration on a mixed route (epidural and intramusculary). 6 cows (Holstein and Montbéliarde) were superovulated according to the following protocol: on day 0 – vaginal application of progesterone spiral (PRID®, CEVA, France); day 7- administration of FSH (Folltropin-V®, Bioniche, Canada) 200 mg epidurally and 200 mg intramusculary; day 9 – administration of 250 mg D- sodium cloprostenol (Prostol®, Syva, Spain) and removal of PRID. Response monitorization was made by ultrasound exams of the ovaries on days 12 (during estrus) and 19 (the day of embrion collection). On average, 14 follicles (minimum 8, maximum 20) and 9 corpora lutea (minimum 6, maximum 12) were identified per donor compared to 15 follicles (min 8 max 22) and 9.5 corpora lutea (7 minimum, maximum 12) per donor in the routine protocols. The results show a very close efficacy to those obtained by classical protocol with daily intramuscular administration of FSH. Due to the epidural administration of FSH, deduction of stres for the donor and of the time of treatment, the method can be used in the protocols of embryotransfer in the cow.
