DOSAGE TO INCREASE OF FERTILITY RATE ECG AND BOVINE POLYCLONAL ANTI ECG AT 48 H OR 60 H AFTER PGF TOWARD ESTRUS AND PREGNANCY IN MADURA CATTLE

This study aimed to elevate of fertility rate eCG and bovine polyclonal anti eCG toward the rate of pregnancy in Madura cows at Bangkalan, Madura. The experimental animal used in this study comprised of 30 cows, with normal estrus cycle and 3 years old of age. The Madura cows are all healthy with a body score of at least 3. The Control Group (p0) was injected with PGF2a 25 mg intramuscular (im) twice on day 0 and day 11. Treatment Group 1 (p1) was injected with PGF2a 25 mg and eCG dosage administration to increase of fertility rate of 750 IU im. Treatment Group 2 (p2) was injected with PGF2a 25 mg and eCG dosage of 750 IU im as dosage to increase of fertility rate and bovine polyclonal anti eCG 750 IU at 48 h or 60 h after PGF. On day 14, the Madura cows both control and Treatment Group respectively showed signs of estrus 100% p >0.05. Few hours’ later artificial insemination was performed on the same day. On day 30, all 30 Madura cows were checked for pregnancy using Ultrasonography (USG). The Madura cows were assumed to be pregnant because there were signs of enlargement in cornua uteri unilaterally. Therefore, this indicates that there was no significant difference between Treatment Group 1 and Treatment Group 2 in pregnancy rate. Based on the results, Control Group (TO) showed 50% of the Madura cows were pregnant. Meanwhile, Treatment Group 1 (T1) 60% and Treatment Group 2 (T2) showed 70% pregnant from Madura cows p > 0.05 on day 35. Therefore, this research showed a positive feedback consistent with the objective.
