Effects of Astragalus, Angelica, Rhodiola on the Growth Performance and Some Physiological Functions of Weaning Piglets

【Objective】 This study was designed to investigate the effect of astragalus,angelica,rhodiola on growth performance and physiological functions of weaned piglets,and to investigate the mechanism of Chinese traditional medicine on anti-EWS.【Method】 Total of 180 crossbred(Duroc×Landrace×Yorkshire) weaning piglets(BW=(10.07±0.21) kg),were selected and randomly divided into 10 groups for 2-week-trial.Group 1 was control group fed with basal diet,group 2,3,4 were experimental group fed with basal diet plus0.5%,1%,1.5% astragalus,group 5,6,7 were fed with basal diet plus 0.5%,1%,1.5% rhodiola,group 8,9,10 were fed with basal diet plus 0.5%,1%,1.5% angelica.【Result】 The results showed that: Comparing to the control group,1)Supplementations with 1%,1.5% astragalus,1.5% rhodiola had the significantly beneficial effects in increasing absolute weight(P0.01,P0.05,P0.05),average daily gain(P0.01,P0.01,P0.01),average daily feed intakes(P0.05,P0.05,P0.05);supplementations with 1% astragalus,1.5% rhodiola had the significantly beneficial effects in decreasing the ratio of feed to gain(P0.05,P0.05).2) Supplementations with 1.5% astragalus,1.5% rhodiola had the significantly beneficial effects in decreasing the content of serum NO on the 7th day(P0.01,P0.05) and on the 14th day(P0.05,P0.05),supplementations with 1%,1.5% astragalus,1.5% rhodiola and 1.5% angelica had the significantly beneficial effects in increasing the activity of serum GSH-Px on the 7th day(P0.01,P0.05,P0.05,P0.05)and on the 14th day(P0.01,P0.05,P0.01,P0.05).3) Supplementations with 1% astragalus,1.5% rhodiola and 1.5% angelica had the significantly beneficial effects in increasing the red blood cell count(P0.01,P0.05,P0.05),supplementations with 1.5% astragalus had the significantly beneficial effects in increasing the blood hemoglobin content(P0.05),supplementations with 1%,1.5% astragalus,1.5% rhodiola and 1.5% angelica had the significantly beneficial effects in increasing the white blood cell count(P0.01,P0.05,P0.05,P0.05),supplementations with 1% astragalus,1.5% rhodiola and 1.5% angelica had the significantly beneficial effects in increasing the lymphocytes percentage(P0.05,P0.05,P0.05),and supplementations with 1% astragalus,1.5% rhodiola had the significantly beneficial effects in increasing the monocytes percentage(P0.05,P0.05).【Conclusion】 From above results,it could be concluded that supplementations with astragalus,rhodiola and angelica had the significantly beneficial effects on increasing antioxidant ability,increasing growth performance and increasing physiological functions in weaned piglets,and 1% astragalus had the best effect,1.5% rhodiola was better,the effect of 1.5% angelica was the least.
