In this study, 15 Kivircik rams aged 1.5 years, were used. After determining the spermatologic characteristics of all individuals, five of the rams were vaccinated to constitute the control group. Mycoplasma agalactiae 99 M (AIK 2) strain was inoculated in all of the rams 34 days after the vaccination. Before the inoculation and 15 days after, semen and blood samples were collected. The agent was isolated in blood on the 7th day after inoculation. Before and after the inoculation, serum zinc and copper levels were measured by using an Atomic Absorbtion Spectrometry. When copper and zinc level results were evaluated it was observed that, before and after inoculation copper level showed a non-significant decrease whilst zinc level had a significant decrease (p0.05). In post mortem examination, variable amounts of degeneration in the testes and an increase in the connective tissue of vesiculae seminales were observed. In conclusion it was suggested that, zinc deficiency played an important role in the formation of disease symptoms.
