| Abstract | ||
| The aim of this study was to diagnose fetal mortality and the time of occurrence using real-time ultrasonography. 118 ewes were included in this experiment, to synchronized estrus of 47 ewes were carried out by using intravaginal sponges containing 40 mg progesterone for 14 days and then injected intramuscularly with 500IU of eCG at the time of sponge withdrawal, while 71 ewes were not treated and left to cycling normally. All ewes were mated naturally. In order to determinate of fetal numbers and observing fetal mortality, ewes were examined by 5MHz real- time ultrasonography at interval 20-24, 25-29, 30-34, 35-39 and after day 40 after breeding. The results showed that embryonic mortality rate in non treated and in treated ewes were 21.4, 45.7% respectively. A high embryonic mortality rate occurred in treated and non treated ewes within 20-24 days of gestation. There was a positive correlation between embryonic number and embryonic mortality in treated ewes. | ||
