These experiments were performed to develope a simple and reliable method of bovine embryo transfer under the field conditions. Of 42 synchronous (+12 hours) recipients, 37 and 5 were received single fresh and frozen embryo, respectively, by nonsurgical method. The results obtained in these experiments were summarized as follows: 1. Of 42 embryos transferred non-surgically, 20(47.6%) survived for more than 45 days after transfer. 2. Ten healthy calves (28.6%) were produced from 35 recipients which received single embryo, respectively. 3. Of 5 frozen embryos imported from Japan, and transferred non-surgically 3 developed to calving normally. 4. Embryos were transferred to recipients in estrus 12 hours later than donor (+12), the same time (0) or 12 hours earlier than donor (-12). The 0 group showed significantly higher (p$lt;0.05) calving rate (33.3%) than +12 group (25.0%) or -12 group (25.0%). 5. Calving rates of blastocyst (31.3%) or hatched blastocyst (30.0%) were significantly (p$lt;0.05) higher than that of morula (22.2%).

Development stages and morphological characteristics of total of 179 bovine ova, non-surgically collected 8 to 9 days after estrus from 39 donor cattle superovulated with PMSG or FSH and Prostaglandin F₂α, were investigated under the phasecontrast microscope, and the following results were obtained. 1. Of 179 ova non-surgically collected from superovulated 39 donor cattle, 24(13.4%) were unfertilized. 2. Development stages of embryos at collection were ranged from morula (30.7%) to blastocyst (49.2%) or hatched blastocyst (6.7%). 3. In the morphological grading of 155 fertilized embryos, excellent, good, fair and poor embryos were 42(27.1%), 44(28.4%), 59(38.1%) and 10(6.4%), respectively. 4. The results described above suggest that the dosage of PMSG (3000IU) and the time of collecting embryo (8 to 9 days after estrus) adapted in this experiment were too much and late to get high percentage of morphologically excellent embryo.
