in dairy cows.

The infusion of ozone into the inflamed quarter of
cows with clinical mastitis was performed and the efficacy of ozone
therapy was evaluated. Ozone was infused into the inflamed quarter via a
teat canal using ozone gas generating equipment. Nineteen Holstein cows
with acute clinical mastitis were divided into two groups: 15 cows
treated with ozone therapy, and 4 cows treated with antibiotic therapy.
Systemic and local clinical signs, California Mastitis Test scores, the
mastitis causing pathogens, electronic conductivity of milk, and somatic
cell counts in milk from ozone- and antibiotic-treated quarters, were
compared between the groups. Sixty percent (9/15) of cows with acute
clinical mastitis treated with ozone therapy, did not require any
antibiotics for recovery. This newly developed ozone therapy method was
proven to be effective, safe, and cost effective, and carries no risk of
drug residues in milk.
