牛至油对东北白鹅免疫器官指数及部分血清生化指标的影响

摘要

The experiment was conducted to determine how could oregano oil affect the growth and slaughter performance,immune organ index,as well as biochemical indicators of blood serum in the Northeast white geese.To this end,the premix oforegano oil was incorporated into the basal diet for the chosen geese.168 goslings were randomly divided into 4 groups withmales and females together.The control group was fed only with the basal diet.While 50 mg/kg,100 mg/kg,150 mg/kg oreganooil premix were added in the diet of test groups.Results reveals that:The addition of 100 mg/kg and 150 mg/kg oreganooil premix (with 10%of quality score)in the diet can improve the immune organ index,increase the content of IgG,IgM,C3,C4 and TP in the serum,decrease LDH activity,enhance the immunity function and raise the anti-stress ability.%研究了东北白鹅日粮中添加牛至油预混剂对其生长性能、屠宰性能和免疫器官指数及部分血清生化指标的影响。168只公母混合鹅雏按试验要求分为4组，对照组饲喂基础日粮，试验各组在基础日粮中分别添加50、100和150 mg／kg的牛至油预混剂。结果表明：在东北白鹅日粮中添加100 mg／kg及150 mg／kg质量分数10％牛至油预混剂可提高免疫器官指数，提高血清中的免疫球蛋白IgG、IgM、总蛋白含量及补体C3、C4水平，降低乳酸脱氢酶活性，增强机体的免疫性能，提高抗应激能力。
