通过检测鹅血清部分抗氧化指标,探讨玉米蛋白多肽对鹅抗氧化功能的影响。选择1日龄昌图豁鹅240只,采取单因子完全随机设计,随机分为4组,分别按每kg饲料添加500,300,100mg玉米蛋白多肽设置高、中、低剂量3个剂量组,不添加玉米蛋白多肽设置为对照组。饲养30,60d,采集鹅血,制备血清,采用紫外分光光度法检测鹅血清中总抗氧化能力（T-AOC）、超氧化物歧化酶（SOD）活力和丙二醛（MDA）含量。结果表明：随着日龄的增加,呈现鹅血清T-AOC水平和SOD活性增加、MDA含量减少的趋势。鹅饲料中较长时间（60d）添加玉米蛋白多肽可使其血清T-AOC水平增加,且与添加剂量正相关;而低剂量水平（100mg）玉米蛋白多肽的短时间（30d）作用会抑制鹅血清的SOD活性,对血清MDA含量影响不大,长时间作用可提高血清SOD活性;中剂量水平（300mg）对血清的T-AOC水平、SOD活性和MDA含量影响不大;高剂量水平（500mg）短时间作用可以有效提高SOD活性、降低MDA含量,但较长时间（60d）作用则显著提高T-AOC水平和MDA含量,提高SOD活性的效果不如低剂量组。 The partial oxidation indices of serum in geese were detected to explore the effects of the corn protein polypeptide on the anti-oxidation function of geese.240 one-day-old Changtu Huoyan geese were randomly divided into four groups by a single factor completely randomized design,one control group was fed basal diet,3-dose groups,high,medium and low-dose,were added 500 mg,300 mg,100 mg corn protein poly-peptide in per kg feed,respectively.At the day of 30th and 60th,the blood of geese was collected to prepare the serum,then the
