黄芪多糖对贵乾半细毛羊疾病发生、生长性能及生化指标的影响
Effect of Astragalus polysaccharides(APS)in Diet on Disease Occurrence,Growth Performance and Biochemical Indexes of Guiqian Semi-fine Wool Sheep
摘要
Abstract
To study the effect of Astragalus polysaccharides(APS)in diets on disease occurrence,growth performance and biochemical indexes of grazing Guiqian semi-fine wool sheep,the study selected 120 healthy six-month-old sheep with similar weight and randomly divided them into control group,test group A,B,and C,with 30 sheep in each group.Each group has three repetition and 10 sheep in each rep-etition.The sheep in control group were fed basic diet,and those in test groups were fed different levels of APS by 1g,2g,and 3g.The pretrial was 15 days,and the trial period was 90 days,during which the sheep were observed for diseases,and their growth performance and blood biochemical indexes were determined.The results showed 1)the incident rate of diseases in Group C was lowest 3.33％,and that of the control was the highest(26.67％).2)The average daily gain of group C was extremely higher than that of the con-trol(P＜0.01),and significantly higher than that of group B and C(P＜0.05);and the concentration feed intake of the control was remarkably lower than that of the test groups(P＜0.05).3)The antioxidant in-dex SOD and GSH-Px were significantly higher in test group C than in the control(P＜0.05).4)The GPT index in group C was remarkably higher than in the control(P＜0.05).Therefore,it is concluded that the addition of Astragalus polysaccharide in diet can increase daily weight gain and improve the immunity and andantioxidant capacity of Guiqian semi-fine wool sheep.关键词
