Embryo transfer technology had been developed under local conditions. Eventhough the principle of technology was simple in general, the suitable technics, special handlings, skills and experiences were required at each step. Attempts to develop the technology in Thailand had been done during the past few years. In 1984-1985, The National Center of Genetic Engineering and Biotechnology had funded the studies. The technics involved synchronization of donor and recipients, superovulation, collection of embryos and the transfer. In 1984-1985, 21 trials of non-surgical flushing had been performed in dairy cattle in Ratchaburi using FSH for superovulation. Moreover, 14 trials using PMSG for superovulation had been done at Kampangsan Dairy Farm, Kasetsart University. Subsequently, the flushes were examined for embryos. The technics had improved gradually from obtaining no embryo in the flushes to obtain many embryos. Transferrings of embryos to the recipients had been attempted but no pregnancy was detected. There were many factors involved in the successful embryo transfer, including management of the dairy. The most important factors were skill and experiences. Further investigations were in progress. The potential impacts of developing embryo transfer technology in Thailand were enormous. Improving reproductive efficiency by embryo transfer coupled with the nutritional and management improving factors of dairy cattle industry in a tropical environment would account for maximum milk yielded in Thailand.
