Effect of Yeast (Saccharomyces cerevisiae) Enhanced with Selenium or Zinc on the Hematological Characteristics in Iraqi Does

Abstract

This study was conducted to investigate the effect of yeast (Saccharomyces cerevisiae) enhanced with Selenium or Zinc on some hematological characteristics in the Iraqi female goats. The seventeen adult female goats 2-2.5 years old with average body weight (bw) 37.5 ± 2.5 kg that have at least one previous birth were used. The animals were randomly divided in to three groups, group 1 have 5 goats, group 2 and 3 have six goats. all doesss were fed same ration. Animals of group 1 (G1) were let without treatment which considered as a control group, Animals of group 2 (G2) was given yeast enriched with selenium (0.03 g/kg/bw), While Animals of group 3 (G3) were given yeast enriched with zinc (0.2 g/kg/bw). The animals were treated by dissolving the samples in 30 ml of distilled water and administered orally for 45 days. Blood samples were collected from the jugular vein during first day (first period), twelfth day (second period) fort- fifth day (third period) to carrying out blood tests. The results showed was significant increase (P≤0.05) in the count of the red blood cells, hemoglobin concentration and Hematocrit of second and third groups as compared with first group. While the second group was significant increase in the number of white blood cells compared with the first and third groups. From the results, it could be concluded that there synergistic effect of Saccharomyces cerevisiae with selenium or zinc may be attributed to improve some hematological aspects in does.
