【摘要】 试验选用216只44周龄海兰褐蛋种鸡随机分为4个处理组,每个处理组3个重复,每个重复18只,研究不同添加量的鲜蛆对蛋种鸡血液生化指标的影响。试验组(1、2、3组)在基础日粮中分别添加5、10、15g·d-1·只-1麦麸培养的鲜蛆(4日龄),对照组饲喂基础日粮。预试期1周,试验期6周。结果表明:与对照组相比,蝇蛆可显著降低试验2组蛋种鸡血清中白蛋白水平(P<0.05),显著降低试验3组白蛋白与球蛋白比值(P<0.05);并可极显著降低试验2组血清中甘油三酯含量(P<0.05),显著提高了试验2、3组血清中高密度脂蛋白胆固醇含量(P<0.01);蝇蛆可显著提高试验3组血清中IgG的含量(P<0.01)。更多还原

【Abstract】 The effects of fresh maggots with different addition on serum biochemical indexes of breeding hens were studied. Two hundred and sixteen Hyline brown chickens at the age of 44 weeks were randomly divided into 4 treatments, each treatment was consisted of 3 replicatiion with 18 chicken. The treatments I-III were fed the basal diet of each chick supplemented respectively with 5, 10, and 15 g·d-1 fresh maggots which were fed by wheat bran, and the control group was fed by basal diet. After one week of pretreatment, all the groups were treated for six weeks. The results showed that comparing with the control group, the level of albumin in serum of breeding hens in group Ⅱ decreased significantly by maggots(P<0.05), the ratio of albumin to globin in group Ⅲ was decreased significantly(P<0.05); the content of triglyceride in serum in group Ⅱ decreased significantly(P< 0.05), the content of high density lipoprotein cholesterin in group II and Ⅲ increased significantly(P<0.01): the content of IgG in group Ⅲ increased significantly(P<0.01). There were no significant differences among treatment groups on other indexes(P>0.05).更多还原
