Superovulation in donors is an important factor influencing ovulation rate and embryo recovery. Crossbreed pubertal gilts (n=376) treated from year 2005 to 2009 were used as embryo donors. Experiment was evaluated in two parts: In the first part (I) gilts were divided into two groups with different synchronization schedules. In the first group (R+) 265 gilts were treated with Regumate Porcine (JANSSEN). In the second group (R-) were gilts (n=111) without Regumate diet. The number of ovulations was higher in R+ group (15.1 plus minus 9.3) compared to R- group (14.9 plus minus 9.3). There was no significant difference (p>0.05) between both groups.
