Oregano essential oil (Lippia origanoids) improves productive parameters and blood metabolites in piglets. Rev.Bio.Agro [online]. 2021, vol.19, n.2, pp.82-93. Epub 30-Jun-2021.

Antibiotics have been used in animal feed in order to ensure more efficient production, however, the appearance of antibiotic resistant bacteria has caused concern in both consumers and scientific. The aim was to evaluate the effect of Lippia origanoides supplementation on the productive performance and the concentration of blood metabolites in piglets weaned at 21 days. 72 piglets weaned on day 21 were used and randomized to 3 diets: (D1) basic feed, (D2) basic feed + zinc bacitracin (350 ppm) and (D3) basic feed + Lippia origanoides (150 ppm). On days 15 and 30 of the experimental period, performance was calculated and metabolic variables were evaluated at serum level. The animals that consumed the D3 diet presented higher feed conversion rate and body weight gain, in addition to presenting higher concentrations (p <0,05) of alkaline phosphatase, calcium and phosphorus, while the concentrations of creatinine, alanine aminotransferase, glucose, triglycerides and cholesterol were found significantly (p <0,05) lower compared to animals that consumed (D1) and (D2). The use of Lippia Origanoides in the piglet diet is an alternative to the use of antibiotics, since it has favorable effects on blood biochemistry and productive performance.
