试验旨在探究饲粮中添加不同比例的蓑荷黄酮对雏鸡生长性能、免疫功能、血浆生化指标及抗氧化功能的影响.选取90只体况相近的7日龄雏鸡,随机分为3组,每组10个重复,每个重复3只鸡.对照组饲喂基础饲粮,Ⅰ组、Ⅱ组分别在基础饲粮中添加100、200 mg/kg蘘荷黄酮.试验期35 d.结果显示,试验第1～14d,Ⅰ组雏鸡平均日增重极显著高于对照组与Ⅱ组(P＜0.01),料重比极显著低于对照组与Ⅱ组(P＜0.01).试验第35 d,Ⅰ组、Ⅱ组雏鸡血浆谷丙转氨酶(ALT)活性极显著低于对照组(P＜0.01),血液H9亚型禽流感病毒、新城疫病毒(HDV)抗体效价均显著高于对照组(P＜0.05),血浆过氧化氢酶(CAT)活性均显著高于对照组(P＜0.05);Ⅱ组雏鸡血浆总蛋白(TP)含量显著高于对照组及Ⅰ组(P＜0.05).试验第35 d,Ⅰ组、Ⅱ组胸腺指数、法式囊指数均显著高于对照组(P＜0.05).研究表明,饲粮中添加适量蘘荷黄酮可以改善雏鸡生长性能、免疫功能、部分血浆生化指标及抗氧化功能,蘘荷黄酮推荐添加量为100 mg/kg.
Effects of Zingiber mioga flavonoids on growth performance,immune function,plasma biochemical indices,and antioxidant function of chicks
The experiment aimed to explore the effects of adding different proportions of Zingiber mioga flavonoids to feed on the growth performance,immune function,plasma biochemical indices and antioxidant function of chicks.Ninety seven-day-old chicks with similar physical conditions were randomly divided into three groups,with 10 replicates per group and three chicks per replicate.The control group was fed a basic diet,while Group Ⅰ and Group Ⅱ were supplemented with 100,200 mg/kg of Zingiber mioga flavonoids in the basic diet,respectively.The experiment lasted for 35 days.The results showed that from the 1st to thel4th day of the experiment,the average daily weight gain of chicks in Group Ⅰ was extremely higher than that of the control group and Group Ⅱ(P＜0.01),and the feed to gain ratio was extremely lower than that of the control group and Group Ⅱ(P＜0.01).On the 35th day of the experiment,the activity of plasma alanine aminotransferase(ALT)in Group Ⅰ and Group Ⅱ was extremely lower than that of the control group(P＜0.01),and the antibody titers against H9 subtype avian influenza virus and Newcastle disease virus(NDV)in the blood were significantly higher than those of the control group(P＜0.05).The activity of plasma catalase(CAT)was significantly higher than that of the control group(P＜0.05).The plasma total protein(TP)content in Group Ⅱ was significantly higher than that in the control group and Group Ⅰ(P＜0.05).On the 35th day,the thymus index and bursa of fabricius index in Group Ⅰ and Group Ⅱ were significantly higher than those of the control group(P＜0.05).The study indicates that the addition of an appropriate amount of Zingiber mioga flavonoids to the feed of chicks can improve growth performance,immune function,partial plasma biochemical indices and antioxidant function,with a recommended addition of 100 mg/kg.
