MethodTwenty-four chickens were randomly divided into three groups (n=8), control group, low temperature group and imidapril group. Chickens in low temperature group and imidapril group were exposed to low ambient temperature (12-18 ℃) from age at 14 d to 45 d, whereas the control group was exposed to 24-30 ℃; chickens in imidapril group were gavaged with imidapril (3 mg/kg) once daily for 30 d. At age of 45 d, blood was taken from wing vein and blood gas parameters were evaluated by blood gas analyzer in Luoyang Central Hospital Affiliated to Zhengzhou University. ResultImidapril significantly increased hematocrit (HCT) and total hemoglobin content (T HBC ) and blood Na concentration in broiler chickens exposed to low ambient temperature. No significant differences were observed in pH, P CO 2 , P O 2 , K + , Ca 2+ , HCO 3-, HCO 3std , T CO 2 , BE and SO 2c . ConclusionImidapril increases hematocrit, total hemoglobin content and blood Na + concentration in chickens exposed to low ambient temperature.展开更多
