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 15days. 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 12.5mg/kg body weight once per day until the age of 10days. "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 15days 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 10days 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.
本研究的目的是在田间条件下评估，每日给15日龄以下的犊牛投喂牛至精油是否能有效预防和/或减轻新生儿腹泻综合征的严重程度。来自三个奶牛场的91头新生犊牛被分为两组；“Eco”组（n = 46）的犊牛每天以12.5mg/kg体重的剂量灌服希腊牛至（牛至属牛至亚种）精油（ECODIAR®液体5%），持续至10日龄。“Conts”组（n = 45）的犊牛不进行治疗，作为对照。每天监测所有动物直至15日龄的腹泻发生率，并记录其粪便评分。在第3、6和10天采集粪便样本进行微生物学和寄生虫学评估。与对照组相比，Eco组在整个实验过程中的平均粪便评分、腹泻发生率、腹泻发作的持续时间和严重程度均显著较低。在犊牛出生后的前10天每天投喂牛至精油，可有效减轻田间条件下自然发生的腹泻的严重程度，并且在某些卫生措施下，对新生儿腹泻综合征具有预防作用。
