本试验旨在探讨葡萄糖氧化酶（GOD）对大河乌猪妊娠母猪繁殖性能、血清抗氧化指标和饲粮养分消化率的影响。选择健康经产（3~5胎）大河乌猪妊娠母猪60头，随机分为4个组，每组15个重复，每个重复1头猪。对照组饲喂基础饲粮，GOD1、GOD2和GOD3组饲喂在基础饲粮中分别添加200、400和600 mg/kg GOD的试验饲粮。母猪产前30 d开始试验，直到仔猪断奶时结束。结果表明：1）与对照组相比，饲粮中添加400和600 mg/kg GOD可增加大河乌猪妊娠母猪的产仔数和产活仔数（P>0.05）；饲粮中添加600 mg/kg GOD可显著增加仔猪初生重和20日龄重（P<0.05）。2）与对照组相比，饲粮中添加600 mg/kg GOD可显著增加大河乌猪妊娠母猪和仔猪血清谷胱甘肽过氧化物酶（GSH-Px）活性和总抗氧化能力（T-AOC）（P<0.05），显著降低血清丙二醛（MDA）含量（P<0.05）。3）与对照组相比，饲粮中添加600 mg/kg GOD可显著增加大河乌猪妊娠母猪饲粮粗脂肪（EE）和磷（P）的消化率（P<0.05）。本试验条件下，大河乌猪母猪妊娠后期（产前30 d）饲粮中添加600 mg/kg GOD可提高母猪的繁殖性能，增强母猪和仔猪抗氧化能力，提高母猪对饲粮EE和P的消化能力，提高饲粮利用率。

This experiment was conducted to investigate the effects of glucose oxidase (GOD) on reproductive performance, antioxidant indexes in serum and dietary nutrient digestibility of Dahe black pregnant sows. Sixty multiparous (3 to 5 parity) healthy Dahe black pregnant sows were randomly divided into four groups with fifteen replicates per group and one sows per replicate. The sows in control group were fed a basal diet, while the others in GOD1, GOD2 and GOD3 groups were fed the basal diet supplemented with 200, 400 and 600 mg/kg GOD, respectively. The experiment period lasted from 30 days before the parturition to weaning of piglets. The results showed as follows: 1) compared with control group, diet supplemented with 400 and 600 mg/kg GOD increased the litter size and number born alive of Dahe black pregnant sows (P>0.05), and diet supplemented with 600 mg/kg GOD significantly increased the birth weight and body weight aged at 20 days of piglets (P<0.05). 2) Compared with control group, diet supplemented with 600 mg/kg GOD significantly increased the activity of glutathione peroxidase (GSH-Px) and total antioxidant capacity (T-AOC) in serum and significantly decreased the content of malonaldehyde (MDA) in serum of Dahe black pregnant sows and piglets (P<0.05). 3) Compared with control group, diet supplemented with 600 mg/kg GOD significantly increased the dietary ether extract (EE) and phosphorus (P) digestibility of Dahe black pregnant sows (P<0.05). Under this experimental condition, diet supplemented with 600 mg/kg GOD in the later period (30 days before the parturition) of Dahe black pregnant sows can improve reproductive performance of sows, enhance antioxidant capacity of sows and piglets, improve the dietary EE and P digestibility of sows and feed utilization rate.
