A Therapeutic Effect of Ozonated Oil

Fortynine quarters from 24 lactating cows with chronic mastitis were selected. The cows were raised on dairy farms in Korea. The 49 quarters with bovine mastitis were divided into control (7 quarters) and experimental (42 quarters) groups. The experimental quarters were assigned to experimental group A (10 quarters), experimental group B (14 quarters), and experimental group C (18 quarters), according to the number of the somatic cells in their milk. The control group was treated with norfloxacin ointment based on the result of sensitivity, twice a day for 3 days. The experimental groups were received 10 mL of ozonated oils infused into the inflamed quarters twice a day for 3 days. After treatment, the milk of the control group contained non-significantly lower numbers of somatic cells and bacteria on day 7 compared with pretreatment levels. Experimental groups A, B and C had fewer somatic and bacterial cells in their milk on day 7 compared with pretreatment levels. Experimental groups B and C had significantly lower numbers of somatic cells in their milk on day 7 than before treatment (p<0.01). However, no significant difference in somatic cell numbers was detected between the control and experimental groups. It was concluded that ozone therapy with ozonated oil applied inflamed quarters afflicted with bovine mastitis might be effective. This therapy might also be used as an alternative to antibiotics for the treatment of bovine mastitis.
