This experiment was accompanied to examine the impact of yeast (Saccharomyces cerevisiae) supplemented with Selenium (se) or Zinc (zn) on the reproductive performance, estrogen and progesterone hormone in local Iraqi female goats. 17 mature does two - two and half years of old were used. The average of body weight (bw) was 37.5 ± 3kg. Animals were randomly divided in to three groups, Five animals were in the first group, six goats were in the second and third groups. All goat does were nursed on the same ration. The group1 was considered as a control group without processing (G1), the group 2 (G2) was administered with (Saccharomyces cerevisiae-selenium) with dose (0.03 g/kg/bw), the third group 3 (G3) were administered with (Saccharomyces cerevisiae -zinc with dose (0.2 g/kg/bw). (given orally for 45 days). The results showed that second and third groups were significantly increase (P≤0.05) in fertility and fertilization rate as compared with G1. G3 was significantly increase (P≤0.05) in the Prolificacy rate as compared with G1 and G2. G2 and G3 were significantly increase (P≤0.05) in the pregnancy rate as compared with G1. while G3 was significantly increase (P≤0.05) in the kidding rate as compared with G1 and G2. Estrogen hormone concentration level of the G2 showed a significant increase (P≤0.05) as compared with G1 and G3. While the progesterone hormone concentration level of the G3 showed a significant increase (P≤0.05) as compared with G1 and G2. From the results we concluded that organic form (yeast supplemented with selenium/zinc) could be credited to enhance the reproductive performance, overall health of kids after birth, progesterone levels and animal health.

This study was conducted to demonstrate the plasma profile of progesterone, estradiol-17β and some blood biochemical attributes (glucose, cholesterol concentrations and alkaline phosphates activity) of Iraqi female dromedary camels (Camelus dromedarius) during different gestation periods. This experiment included 5 multiparous, non-lactating Iraqi one-humped female camels (Camelus dromedarius) of 7-8 years old. Blood was collected from female camels at days 20, 30, 40, 50, 60, 90, 120,. The plasma progesterone concentrations did not significantly differ among days 20-120 PM. Greater (P≤ 0.05) progesterone concentrations were observed at days 150 and 180 PM as compared with days.20, 30 and 40 PM. No remarkable alterations in plasma estradiol-17β concentrations were seen among different gestation periods. Non-significant variations were detected in plasma glucose concentrations during the entire gestation periods studied (day 20-60 PM). Higher (p<0.05) cholesterol concentrations were observed at days 20 (9.86 ± 0.59 mg/dl) and 30 (8.84 ± 0.32 mg/dl) in comparison with their counterpart values at days 50 (7.06 ± 0.1 mg/dl) and 60 (6.29 ± 0.26 mg/dl) PM. The overall mean of plasma alkaline phosphatase activity did not alter during the whole study period. In conclusion, the pronounced changes during gestation period in dromedary camels can be detected through sex hormones and plasma cholesterol concentrations.

The aim of this study was to diagnose fetal mortality and the time ofoccurrence using real-time ultrasonography. 118 ewes were included in thisexperiment, to synchronized estrus of 47 ewes were carried out by usingintravaginal sponges containing 40 mg progesterone for 14 days and theninjected intramuscularly with 500IU of eCG at the time of sponge withdrawal,while 71 ewes were not treated and left to cycling normally. All ewes weremated naturally. In order to determinate of fetal numbers and observing fetalmortality, ewes were examined by 5MHz real- time ultrasonography at interval20-24, 25-29, 30-34, 35-39 and after day 40 after breeding. The results showedthat 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 nontreated ewes within 20-24 days of gestation. There was a positive correlationbetween embryonic number and embryonic mortality in treated ewes.
