| Popis: | The objective of this study was to evaluate under field conditions, whether daily administration of oregano essential oil is effective in preventing and/or diminishing the severity of neonatal diarrhea syndrome in calves aged less than 15 days. Ninety-one newborn calves from three dairy farms were assigned into two groups; “Eco” group (n = 46) calves were drenched with Greek oregano (Origanum vulgare ssp. Hirtum) essential oil (ECODIAR® liquid 5%) at the dose of 12.5 mg/kg body weight once per day until the age of 10 days. “Conts” group (n = 45) calves were left untreated and served as controls. All animals were monitored daily for the incidence of diarrhea until the age of 15 days and their fecal score was recorded. Fecal samples were collected on days 3, 6 and 10 for microbiological and parasitological evaluation. Average fecal score throughout the experiment, incidence of diarrhea, duration and severity of diarrhea episodes were significantly lower in Eco group compared to the controls. Daily administration of oregano essential oil in calves for the first 10 days of their life effectively diminishes the severity of naturally acquired diarrhea under field conditions and, under certain hygiene practices, possess a preventive effect against neonatal diarrhea syndrome. Highlights • We evaluated the efficacy of oregano essential oil against calf neonatal diarrhea syndrome. • Ninety-one calves from 3 farms were assigned in to two groups. • Oregano essential oil was orally drenched (12.5 mg/kg) once per day from birth until day 10. • Diarrhea incidence was significantly lower in calves receiving oregano oil than the controls. • The severity of diarrhea was significantly lower in calves receiving oregano oil than the controls. |
