The high-spike CT protocol without ECG monitoring reduced the radiation exposure by 55% compared to the protocol with ECG monitoring (from 13.44 mSv to 6.07 mSv). Web10 days and 1000 IU eCG on day 8 (G2); 1000 IU eCG on day 0 and 5 ml PGF 2α on day 10 (G3); control (G4). At the end of treatment, animals in heat were naturally mated. Results showed that follicular diameter (FD) decreased in G2 pre-treatment, increased in G2 and G3 and decreased in G1 at mating compared with G4 (P<0.05).
