传染性法氏囊炎的诊断及耐过鸡群生产指标的跟踪调查报告

The diagnosis of infectious bursitis and the follow-up investigation report on the production index of chickens that Infectious Bursal Disease

鸡群传染性法氏囊病的免疫非常重要。本文通过对实验组和对照组的生长及生产性能等指标的跟踪调查,对比发现,耐过鸡群体重偏低,死淘率较高,免疫应答离散度较大,产蛋率相对较低。究其原因,是耐过鸡只影响全群。

It is very important for chickens to be immune to Infectious Bursal Disease.This article investigates the growth and production performance of the experimental and comparative groups,by comparison,we found that the chickens who had been immunized with Infectious Bursal Disease were low in weight,had a higher mortality and elimination rate,and had a greater dispersion of immune responses and lower egg production rate.The reason is that one chicken-chicken Infectious Bursal Disease affects all the chickens.
