【摘要】：本试验选取108羽1日龄AA肉鸡,随机分为6组,每组设3个重复。第1组饲喂常规饲料;第2组饲喂霉变饲料;第3~5组分别饲喂添加0.05%、0.1%和0.2%酯化葡甘露聚糖(EGM)的霉变饲料;第6组饲喂添加0.1%霉可吸的霉变饲料,研究霉变饲料中添加EGM对肉鸡肝脏霉菌毒素含量和免疫功能的影响。结果表明:与饲喂霉变饲料组相比,霉变饲料中添加0.1%、0.2%EGM和0.1%霉可吸,肉鸡肝脏中黄曲霉毒素B1(AFB1)含量分别降低了62.02%、79.44%和57.27%,玉米赤霉烯酮(ZEN)含量分别降低了66.33%、70.72%和52.01%,呕吐毒素(DON)含量分别降低了55.72%、81.33%和81.05%(P0.05);肉鸡血液新城疫(NDV)抗体水平分别提高了36.86%、66.27%和52.94%,传染性法氏囊病(IBDV)抗体水平分别提高了26.81%、46.81%和32.72%,淋巴细胞转化率分别提高了13.22%、14.83%和13.31%(P0.05)。霉变饲料中添加0.2%EGM时,肉鸡肝脏AFB1、ZEN含量及血液NDV、IBDV抗体水平与对照组差异不显著(P0.05)。综上,EGM可以有效吸附AFB1、ZEN和DON,霉变饲料中适宜添加剂量为0.2%。
[Abstract]:108 1-day-old AA broilers were randomly divided into 6 groups with 3 replicates in each group. Group 1 was fed with normal diet, group 2 with mildew feed, group 3 with 0. 05% and 0. 2% of esterified glucomannan (EGM), respectively. The sixth group was fed with 0.1% mildew absorbable mildew feed to study the effect of EGM on the content of mycotoxin in liver and immune function of broilers. The results showed that the content of aflatoxin B1 (AFB1) in the liver of broilers was decreased by 62.02% and 0.1% EGM and 0.1% mildew in the moldy diet, respectively, compared with that in the moldy feed group, and the content of aflatoxin B1 (AFB1) in the liver of broiler chickens decreased 62.02%, respectively. 79.44% and 57.27%, the content of (ZEN) decreased 66.33% and 52.01%, the content of (DON) decreased 55.72% and 81.05% respectively (P0.05). The level of (NDV) antibody to Newcastle disease in broiler blood increased by 36.86% and 52.94%, and the (IBDV) antibody level of infectious bursal disease increased by 26.81% and 32.72%, respectively. The lymphocyte transformation rate increased by 13.22% 14.83% and 13.31% respectively (P0.05). The content of AFB1,ZEN in liver and the level of serum NDV,IBDV antibody in broilers fed with 0.2%EGM were not significantly different from those in control group (P0.05). In conclusion, EGM can effectively adsorb AFB1,ZEN and DON, mildew in feed with an appropriate dosage of 0.2.
