Researchers from the National University of Colombia have found that oregano could be a viable alternative to antibiotics for treating salmonellosis in chickens. Their study, published in Diario Veterinario, involved 40 laying hens infected with S. gallinarum, divided into five groups. Three groups received different mixtures of oregano essential oils, organic acids, and beta-glucan polysaccharide. Over 10 weeks, the second mixture, which included lactic and formic acid, reduced salmonellosis by 61% and boosted productivity and egg production. The findings suggest that these natural additives have protective effects and could be developed into specific nutritional supplements.
