Abstract
Forty- nine quarters from 24 lactating cows with chronic mastitis were selected. The cows were raised on dairy farms in Gongju, Jochiwon and Yeongi in Chungnam province, and Iksan in Jeonbuk province, 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, somatic cell count: $50-100\times10^4/ml)$, experimental group B (14 quarters, somatic cells count: $100-300{\times}10^4/ml)$, and experimental group C (18 quarters, somatic cells count: $>300\times10^4/ml$), according to the number of the somatic cells in their milk. The quarters of control group were treated with norfloxacin ointment (10 g/tube) based on the result of sensitivity, twice a day for 3 days. The quarters or experimental groups were infused 10ml or ozonated oils 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 lower somatic and bacterial cells in their milk on day 7, compared with pretreatment levels. Experimental group B and C had significantly lower numbers of somatic cells in their milk ell day 7 than before treatment (p<0.01). However, no significant difference in somatic cell numbers was detected between the control alld experimental groups. It was concluded that ozone therapy with ozonated oil applied on bovine mastitis might be effective.
