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.
本研究旨在评估蜂胶乙醇提取物对哺乳期前犊牛的生产性能、粪便结构和整体健康状况的影响。为此，选择了 24 头西木尔牛犊，这些牛犊在出生后的头 3 天内接受了初乳。研究从犊牛 4 天大时开始，60 天大时结束。这些犊牛根据体重和性别分为蜂胶组和对照组。两组均给予相同的日粮，并在相同的环境条件下饲养在单独的犊牛舍中。与对照组不同的是，蜂胶组的犊牛在早上喂食后，连续 56 天每天用口服注射器给予 4 毫升蜂胶提取物（300mg/mL）。记录犊牛的采食量和粪便评分。每周记录健康评分、直肠体温、粪便 pH 值、体重和体尺。为了确定乳酸菌和双歧杆菌的数量，在研究开始和结束时采集粪便样本。结果表明，口服蜂胶对一些生产性能参数、腹泻天数和粪便评分有积极影响。本研究表明，蜂胶提取物有可能对哺乳期前犊牛的生长性能和健康状况产生积极影响。
