摘要
为了测定葡萄糖氧化酶对仔猪生长性能、健康、饲料养分利用率的影响,试验将160头28日龄断奶的三元杂交（杜×长×大）健康仔猪按体重随机分为4组,每组4个重复,每个重复10头。对照组饲喂常规断奶仔猪基础日粮,试验1,2,3组分别饲喂含10,20,30 U/kg葡萄糖氧化酶的日粮,试验持续30 d。结果表明：葡萄糖氧化酶可显著提高仔猪饲料能量、蛋白质、脂肪和纤维消化率（P〈0.05）,生产性能和健康水平明显改善,试验组平均日增重比对照组提高12.15%～24.83%,料重比下降7.09%~10.64%（P〈0.01）;腹泻率降低24.58%~49.76%（P〈0.05）,死淘率降低12.35%~55.76%（P〈0.05）。说明葡萄糖氧化酶在仔猪日粮中的适宜添加量为30 U/kg。
To determine the effect of glucose oxidase on growth performance, health, the rate of feed nutrient utilization in piglets. One hundred sixty healthy 28 - day - old weaned three - way cross piglets with Duroc, Landrace and Large, were randomly divided into four groups with four replicates of ten each by body weight. The control group was fed basal diet for piglet while the experimental groups were fed diets containing 10, 20, and 30 U/kg of glucose oxidase respectively. The trial lasted 30 days. The results showed that glucose oxidase could significantly increase （ P 〈 0.05 ） the digestibility of energy, protein, fat and fiber in feed, and could significantly improve the productive performance and health level of piglets. Compared with the control group, the average daily gain of the experimental group increased by 12.15 % to 24.83%, and the feed conversion ratio dropped by 7.09% to 10.64% （ P 〈 0.01 ） ; the rate of diarrhea reduced by 24.58% to 49.76% （ P 〈 0.05 ）, and the ratio of mortality to elimination decreased by 12.35% to 55.76% （ P 〈0.05 ）. The results indicate that the suitable dosage of glucose oxidase in piglets diets was 30 U/kg.
