This study was conducted on 44 newborn Holstein Friesian calvesraised in a private farm in Hatay province, Turkey. The calves weredivided into two groups; the first group (control group) was fed onlywith milk replacer and the second group was fed with milk replaceradded 893 mg oregano oil (oregano oil group) from the fourth day aftercalving. The amount of milk replacer offered to the calves was 10% oftheir weekly live weights. The calves were weaned when theyconsumed 800 g concentrate feed daily for three consecutive days.Weaning age and daily live weight gains for control and oregano oilgroup calves were found as 68.6 ± 4.45, 67.7 ± 4.62 days and 0.300 ±0.09, 0.400 ± 0.011 kg, respectively. The mean consumption of milkreplacer, hay and concentrate feed of calves for the control andorageno oil calves were found as 327.7 ± 42.17, 331.0 ± 49.40 liters;13.25 ± 3.025, 15.23 ± 3.682 kg and 19.97 ± 4.186, 22.37 ± 5.709 kg,respectively. The average initial hay, and concentrate feed consumingages and diarrhea days for the control and oregano oil groups weredetermined as 10.6 ± 0.29, 9.5 ± 0.28 and 3.1 ± 0.111, 1.9 ± 0.073 days.The initial hay and concentrate feed consuming ages were the same inboth groups. According to the results of the study, more research isneeded to evaluate the optimal dosing of oregano oil.
