[The course of ovulation in gilts after the use of two GnRH injections for ovulation stimulation].
The status of ovulation and amount of ovulated follicles in 410 gilts which had received differentiated pretreatment produced evidence to the feasibility of substitution of HCG by Gn-RH vet. "Berlin-Chemie" to stimulate ovulation. Yet, 2 injections are necessary with an adequate interval between them and with appropriate dosage. The highest synchronisation effect in all experimental variants was obtained from 350 and 750 micrograms of Gn-RH with 50 minutes in between or 750 plus 750 micrograms of Gn-RH with an interval of 40 minutes. Ovulation was most reliably stimulated by 500 I.U. of HCG.
