Efecto del aceite ozonizado en mastitis subclínica de pequeños rumiantes en la zona baja de la Provincia de El Oro.

Abstract

Mastitis is an inflammatory response in the mammary gland, which occurs as a response to the invasion through the nipple canal of different types of bacteria, mycoplasmas, fungi, and yeasts. This disease can be both subclinical and clinical, and among some of the macroscopic alterations we observe are milk changes, swelling, redness, and in severe cases ulcers leading to gangrene. Various types of diagnosis exist, including chemical tests such as the California Mastitis Test, electrical conductivity method, and somatic cell count in milk. The aim of the present research is to evaluate the effect of ozonized olive oil as a treatment for subclinical mastitis in sheep and goats in the cantons of Arenillas, Santa Rosa, and Huaquillas in the province of El Oro. The California Mastitis Test was used as the diagnostic method, and milk samples were collected from 60 animals consisting of sheep and goats, where a prevalence of 15% of the total sample was obtained, meaning only 9 animals tested positive for the disease. Regarding treatment effectiveness, an 80% success rate was achieved, meaning that out of the 5 treated animals, only one remained positive. Regarding age, the study reveals that ozonized olive oil showed high effectiveness in treating the disease in animals aged between 2 and 3 years, with a 100% success rate. However, efficacy decreased in animals aged 4 to 5 years, with only 50% effectiveness. On the other hand, in animals aged 6 to 7 years, a 100% effectiveness rate was again achieved. These findings suggest that age may influence the response to treatment with ozonized olive oil.
