Resumo:  The aim of this study was to evaluate the effects of green tea (Camellia sinensis) and oregano (Origanumvulgare) extracts on behavior, weight gain, and health indicators of dairy calves from birth to 60 days ofage. Twenty-one Jersey calves were distributed into three treatments: without additives (CON); green teaextract (GT): supply of 30 mg/kg of body weight/day; and oregano extract (OR): supply of 60 mg/kg ofbody weight/day. Observers registered animal?s behavior at 5-minute intervals from 8:00 to 16:00, threetimes a week, from day 1 to day 60 of life. The behavioral variables considered were time spent instanding, lying down, ruminating, frequency of visits to feeders, frequency of eating pasture and straw, aswell as body weight gain, body temperature, heart and respiratory rates, and health conditions. GT andOR anticipated the occurrence of thefirst rumination and the ingestion of straw in approximately 7 dayscompared with CON but did not modify the body weight gain, incidence of diarrhea, health conditions,and other behavioral variables. Supply of GT and OR stimulated the onset of dry feed intake and rumi-nation without changing performance and health status.
