自然霉变玉米对肉鸭生产性能及免疫功能的影响
Effects of Natural Moldy Corn on the Growth Performance, Anti-Oxidative Function and Immune Function in Ducks
摘要
Abstract
This study was conducted to determine the effects of the natural moldy corn with aflatoxin B1 (AFB1) as the main mycotoxin on the performance, anti-oxidative function and immune function of ducks. A single factoral design was used with three levels of natural moldy corn (0, 50%, 100%) to substitute the normal corn. Three hundred and eighty-four ducks were randomly allotted by body weight into 3 treatments with 8 replicates of 16 ducks (8 males and 8 females). The trial lasted for 5 weeks. Results showed that with the increase of moldy maize, average daily feed intake, Average daily gain at 1 ~35 d, and Feed/gain at 15 ~35 d was significantly linearly decreased (P<0.01), and mortality significantly linearly increased (P<0.01). The activities of serum superoxide dismutase at 14 d, 35d and Catalaseof liver at 14 d was significantly decreased (P<0.01), while the content of serum Malondialdehydeat 14 d was increased significantly. The relative weight of spleen at 14 d, 35 d, bursa of Fabricius at 14 d, liver at 35 d was significantly increased. The serum Total protein, albumin, globulin (except 35 d), and A/G at 14 d and 35 d was significantly decreased (P<0.01). The specific antibody titer to bird flu H5N1 tended to decrease. In conclusion, the naturally moldy corn decreased the feed intake, body weight, and F/G, while increased the mortality of ducks with oxidative stress and immune function damaged.关键词
