Abstract: This study aimed to evaluate the effects of Saccharomyces cerevisiae fortified with organic selenium on the milk constituents of the local goats. Twelve does were 2.5-3 years of age and had body weight averaging 40±2.5 kg. The goats were divided randomly into two groups; each group includes six does. All goats were fed the standard ration. The treated group (G1) was administered (Saccharomyces-cerevisiae-selenium) (0.03 g/kg/bw), and was given orally for four weeks. The second control group (G2) was late without treatment, the milk samples were collected weekly. The results showed that the group G1 that there administrated Saccharomyces cerevisiae-selenium was significantly increased (P≤0.05) in fat and lactose %, compared to the control group, while the results of physical properties of milk showed non-significant differences between the treated group and control group. From these results, it was concluded that Saccharomyces cerevisiae has synergistic activity with selenium as an organic form to improve the fat and lactose percentage of goat’s milk.
