Impact of Saccharomyces cerevisiae enriched with Selenium or Zinc on reproductive performance, estrogen and progesterone hormone in local Iraqi female goats

Abstract

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.
