Impact of Biological Stress Factors in the Breeding Environment on BroilersImmune Function
To better understand the effect of different breecling environments on broilers immune function,the concentrations of aerohic bacteria,fungi,and endotoxins in the air of the chickens houses were determined periodically,and meanwhile.Newcastle Disease antibody(ND-Ab)levels and immune organ indexes of broilers were detected.In this study,320 0ne-day-old healthy Arbor Acres(AA)broilers were randomly divided into two groups,i.e.,Experimental Group(EG)and Control Group(CG),and bred in the chicken houses of different sanitary environmental management conditions.The experiment was done twice(Trial I and Trial 2).Determin concentrations of the airborne aerobic hacterial,the airhorne fungal,the airborne endotoxin and detect the ND-Ab levels and thymus index.The results showed that,poor quality of a chicken house resulted in increase of microbial aerosol level,and negatively affected hroiler bodys immune function.
