The treatment were: P1= 50% Ovaprim + 50% PGF2 α (0,35 ml ovaprim + 1250 μg PGF2 α/kg body weight), P2 = 75% Ovaprim + 25% PGF2 α (0,3 ml ovaprim + 625 μg PGF2 α/kg body weight), P3 = 25% Ovaprim + 75% PGF2 α (0,18 ml ovaprim + 1875 μg PGF2 α/kg body weight), P4 = 100% Ovaprim (0,7 ml ovaprim/kg body weight), P5 = 100% μg PGF2 α (2500 μg PGF2 α/kg body weight). The fastest result of latent time was 6,33 (6 hour 20 minutes), amount of eggs ovulation 76,19 eggs/g, egg diameter additional 0,3 mm and egg maturity additional 10,67%.otherKissing GouramyOvaprimProstaglandinOvulationLaten timeEgg diameterEgg maturityArticle
