添加蜂花粉喂饲对肉杂鸡抗氧化功能的影响

Effects of Bee Pollen on Anti-oxidation Function in Hybrid Broilers

目的:研究蜂花粉对肉杂鸡抗氧化功能的影响。方法:272只1日龄肉杂鸡(科宝1 500♂×海赛克斯♀)随机分为4组,每组68只,公母各半。Ⅰ组为空白对照,Ⅱ,Ⅲ,Ⅳ组分别添加0.5%,1.0%,1.5%的蜂花粉。14,28,42 d时每组随机抽取8只心脏采血,分离血清,测定超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GSH-Px)活力及丙二醛(MDA)含量。结果:添加不同剂量蜂花粉可显著(P<0.05)或极显著(P<0.01)增加肉杂鸡血清中SOD,CAT,GSH-Px活性,降低MDA含量。结论:肉杂鸡日粮中添加蜂花粉在一定程度上具有清除体内自由基,减少脂质过氧化物产生,提高体内抗氧化酶活性的功效。

Objective：To study the effects of bee pollen on anti-oxidation function in hybrid broilers. Methods：272 one-day-old hybrid broilers （COBB 1500 ♂ ×HISEX ♀） were randomly divided into 4 groups, there were 68 broilers （34 cocks and 34 hens） every group. Group Ⅰ was the contrast group; groups Ⅱ, Ⅲ, Ⅳ were treatment groups, with 0.5 %, 1.0%, 1.5% bee pollen respectively. At 14, 28, 42days old, 8 broilers were randomly selected every group, blood serum -were collected to determinate the activity of SOD, CAT and GSH-Px, and the content of MDA. Results： Added bee pollen at different doses had significantly （P 〈 0.05, P 〈 0.01 ） increased the activity of SOD, CAT and GSH-Px, and decreased the content of MDA in serum of hybrid broilers. Conclusions： By adding bee pollen, free radical was scarenged effectively, the production of lipid over oxide was decreased, and the activity of anti-oxidase was improved.
