摘要
本试验利用自行合成的皮质酮——牛血清白蛋白作为抗原,分别在1、2、3周龄给Z-3系北京鸭进行皮下多点免疫注射。经注射的鸭在第5、6周血清结合~3H-皮质酮的能力明显提高,表明有低量抗体产生。对免疫后鸭的生长速度、饲料利用率和胴体性质进行分析,发现5周龄后试验组总体平均体重显著高于对照组;试验组屠宰前(7周龄)体重为2719±331克,显著高于对照组(2517±373克)(P【0.01);但试验组和对照组没有表现瘦肉率、脂肪率以及饲料利用率的差别。
The effects of immunization against corticosterone has been examined on growth rate, feed conversion efficiency and carcass traits in Beijing ducks ( Z-3 strain ) . Corticostcronc-BSA were injected subcutancously at the ages of 1,2,3 weeks. A significant stimulation of growth was observed in the treated ducks after 5 weeks age. The treated ducks were significantly heavier than those of control at slaughter age ( P<0.01 ) . The treated ducks also had a heavier lean meat. No significant effect was observed in female ducks and on feed conversion efficiency, carcass percent lean meat and fat.
