文章旨在研究黄芩提取物(Scutellaria Baicalensis Extract,SBE)对肉鸡生长性能、抗氧化功能及免疫器官指数的影响.试验将 400 只 1 日龄黄羽肉鸡随机分为 4 组,参考《黄羽肉鸡营养需求量》(NY/T 3645-2020)饲喂基础日粮,每组 4 个重复,每个重复 25 只.各组自由采食和饮水.其中CON组提供清水,其余 3 组分别在饮水中添加100 mg/L(100 SBE组)、200 mg/L(200 SBE组)、300 mg/L(300 SBE组)的黄芩提取物.试验为期 28 d.结果:(1)与CON组相比,200 SBE组、300 SBE组肉鸡末重显著提高7.82%、7.15%(P＜0.05),平均日增重显著提高8.50%、7.76%(P＜0.05),料重比显著降低 8.08%、7.07%(P＜0.05).(2)与CON组相比,100 SBE组、200 SBE组、300 SBE组肉鸡血清T-AOC显著提高(P＜0.05),MDA含量显著降低(P＜0.05),且SOD活性极显著提高(P＜0.01).(3)与CON组相比,100 SBE组、200 SBE组、300 SBE组肉鸡法氏囊指数显著提高(P＜0.05),300 SBE组肉鸡脾脏指数显著提高(P＜0.05).结论:日常饮水中加入黄芩提取物能提高肉鸡生长性能、抗氧化功能及免疫器官指数.综合考虑经济效益和耐受性,黄芩提取物的适宜添加水平为 200 mg/L.
The effects of Scutellaria Baicalensis extract on growth performance,antioxidant function,and immune organ index in broiler chickens
This experiment aims to investigate the effects of Scutellaria Baicalensis extract(SBE)on the growth performance,antioxidant function,and immune organ index of broiler chickens.Select 400 1-day yellow feathered broiler chickens and randomly divide them into 4 groups.Refer to the Nutrient Requirements for Yellow feathered Broilers(NY/T 3645-2020)and feed them with a basic diet.Each group has 4 replicates,with 25 chickens per replicate.Each group is free to feed and drink water.The CON group provided clean water,while the other three groups added 100 mg/L(100 SBE group),200 mg/L(200 SBE group),and 300 mg/L(300 SBE group)of Scutellaria Baicalensis extract to their drinking water.The experiment lasted for 28 days.Results:(1)Compared with the CON group,the 200 SBE and 300 SBE groups significantly increased the final weight of broiler chickens by 7.82%and 7.15%(P＜0.05),and the average daily weight gain significantly increased by 8.50%and 7.76%(P＜0.05).The feed to weight ratio significantly decreased by 8.08%and 7.07%(P＜0.05).(2)Compared with the CON group,the serum T-AOC of broiler chickens in the 100 SBE,200 SBE,and 300 SBE groups was significantly increased(P＜0.05),the content of MDA was significantly reduced(P＜0.05),and the activity of SOD was significantly increased(P＜0.01).(3)Compared with the CON group,the 100 SBE group,200 SBE group,and 300 SBE group of broiler chickens showed a significant increase in the bursal index(P＜0.05),while the 300 SBE group of broiler chickens showed a significant increase in the spleen index(P＜0.05).Conclusion:Adding Scutellaria Baicalensis extract to daily drinking water can improve the growth performance,antioxidant function,and immune organ index of broiler chickens.Taking into account both economic benefits and tolerance,the appropriate level of addition for Scutellaria Baicalensis extract is 200 mg/L.
