Preliminary Investigation of Effect of Egg Yolk Peritonitis and Avian Leucosis on Mortality and Laying Rate of Breeder
摘要
Abstract
The aim of this study was to investigate effect of egg yolk peritonitis and avian leucosis on the morbidity and mortality of breeder.In this experiment,we observed clinical symptom and pathological anatomy of morbidity and mortality of 4 breeds of chickens,Lingnan broiler chick-ens,Hua chickens,Cao chickens and Huangjiao Ma chickens from January 2016 to mid-April 2017 in a Jiangsu breeder farm.At the same time,the daily data of mortality and laying rate,immunity and medication of chicken deaths,and the mortality and laying rate in different periods were recor-ded and analyzed.And then the differences between laying rate and egg production rate at peak period of different breeds in contrast with the normal(reference value,80%)were compared.The results showed that there were egg yolk solidified in the intestines,and the tubal swollen,filled with white or yellowish cheese from the dead chicken anatomy,and this symptom was diagnosed egg yolk peritonitis.There were hepatosplenomegaly,mesentery or chest wall tumor like objects of chicken which was diagnosed avian leukosis.At the later laying period,Lingnan broiler chick-ens' mortality was extremely significantly higher than that in the rising and peak period(P<0.01),and Huangjiao Ma chickens' mortality was extremely significantly lower than that in the peak period(P<0.01).The average laying rates of Hua chickens,Cao chickens and Huangjiao Ma chickens were less than 60%,extremely significantly lower compared to that of the reference value(80%)in the peak period(P<0.01).The results indicated that there was serious influence on the chicken farm by egg yolk peritonitis and avian leucosis w hich led to the reduction of laying rate and increase of mortality.There was no radical cure although anti-stress and nutritional medi-cine had a preventive effect,and there was no effective treatment at the moment.关键词
