Abstract


The research was aimed to find the best time for giving Anti-PMSG to produce
embryos and unweaned in mice. The research used twenty-eight mice for producing
embryo and twenty-eight mice for produce unweaned, divided into four groups. Control
group was superovulated with 5 I.U. PMSG and 5 I.U hCG subcutaneously. The groups 1, 2, 3 were superovulated by 5 I.U. PMSG/SC, then, after twice, were treated with 5 LU. hCG/SC and each group treated with 1 : 20 dilution of anti-PMSG 1 hour before, during and 1 hours after LH administration. The result showed that optimal time for giving anti-PMSG was determined at 1 hour before the administration and there was an increase in the number of mice embryos and unweaned (p < 0.01).
