Abstract :
In vitro fertilization (IVF) is a technique that is expected to provide superior livestock mass production, but the problem is that the materials needed still have to be imported at a high price as well. Optimization of IVF technique can be implemented by supplementing materials which are cheap and easily available in the country. Indonesia has a national racehorse, the thoroughbred. In pregnant mare serum there is insulin-like growth factor-I (IGF-I) which is expected to be utilized to improve the outcome of in vitro fertilization. This study aimed to verify the effect of pregnant thoroughbred mare serum derived IGF-I supplementation into in vitro fertilization media on the increase of oocyte maturation and embryo cleavage rates. Oocyte maturation with the supplementation of IGF-I eluate were compared to those of the patent IGF-I, each with a concentration of 5, 10 and 20 ng/ml as well as to those of the negative control (oocyte maturation without supplementation) and the positive control (oocyte maturation supplemented with 15 IU pregnant mare serum gonadotropin (PMSG). Matured oocytes were then inseminated with frozen semen of elite bull. The observed variables were the percentage of cleaved embryos at 48 hours after fertilization. Results of IVF showed that the percentage embryo cleavage were not significantly different (p >0.05) between group supplemented with IGF-I eluate, patent IGF-I and the positive control (PMSG), but were significantly different (p <0.05) compared to the negative control. Conclusion: pregnant thoroughbred mare serum IGF-I eluate increased embryo cleavage rates.
