EFFECTIVENESS OF OZONE TREATMENT IN CURING UTERINE INFECTIONS AND ASSOCIATED MASTITIS IN DAIRY ANIMALS

Abstract

To find the association between uterine infection and mastitis and to compare the effectiveness of ozone treatment and antibiotics in curing these infections, 200 dairy cows were screened by culturing uterine and milk samples on blood agar containing 5% sheep blood. A total of 52 animals either suffering from mastitis or uterine infections were isolated and divided into four groups to receive antibiotic or ozone treatments i.e., MA (mastitis animals treated with antibiotics), MO (mastitis animals treated with ozone), UA (uterine infected animals treated with antibiotics) and UO (uterine infected animals treated with ozone). The UA and UO groups were further treated with ovsynch estrus synchronization protocol  on 14th day after the start of ozone or antibiotic treatment. The estrus response and pregnancy rate were determined to evaluate the efficiency of ozone or antibiotic treatment in uterine infected animals. The results showed a significant (P<0.05) association between uterine infection and mastitis based on the presence of common pathogen. The cure rates in MO (53.8%) was higher (P<0.05) than MA (23.1%). Similarly, estrus response and pregnancy rate were significantly higher (P<0.05) in UO group than UA group.  In conclusion, ozone therapy is more effective in curing mastitis and uterine infections.
