The aim of this study was to evaluate the effect of propolis ethanol extract, on performance, fecal structure, and general health status of calves during the preweaning phase. For this purpose, 24 Simmental calves that were given colostrum for the first 3 days after birth were enrolled in the study. The study started when the calves were 4 days old and finished when they were 60 days old. These calves were divided into two groups as propolis and control groups according to their weight and gender. Both groups were given the same ration and housed in individual calf huts under the same environmental conditions. Differently from the control group, the calves in the propolis group were given 4 mL of propolis extract (300 mg/mL) with an oral feeding syringe for 56 days after morning feeding. The amounts of feed intake and fecal scores of the calves were recorded daily. Health scores, rectal body temperature, fecal pH, body weight, and body measurements were recorded weekly. For the determination of the counts of Lactobacillus spp. and Bifidobacterium spp., fecal samples were collected at the beginning and at the end of the study. The results indicated that oral administration of propolis had positive effects in terms of some performance parameters, the number of days with diarrhea, and fecal scores. In this study, it was concluded that propolis extract had the potential to positively affect the growth performance and health status of preweaning calves.
