- Predict the future characteristics of the prevalence of poultry disease
Poultry disease in recent years more and complex, new disease emerging, old diseases have become increasingly prominent phenomenon of growing, to the breeding and veterinary workers, clinic owners Avian 带来 the many difficulties, in 2010 Avian Rengjiangchengxian the following features.
First, immunosuppressive diseases remain the top priority of Vector Control Immunosuppressive diseases will occur, in addition to their own death or to reduce production of poultry production performance of the direct economic losses, more importantly, indirect losses, such as lead to increased susceptibility to other diseases or harmful to strengthen.
Common immunosuppressive diseases, the chicken infectious anemia, avian reticuloendothelial cell hyperplasia, Marek's disease, avian leukosis, chicken reovirus disease, avian flu and other infectious bursal disease.
Immunosuppressive diseases and treatments against similar, are described only as examples of infectious bursal disease. Bursa is a bird of humoral immune organs, and its direct impact on health or other vaccine, 15 to 25 days is infectious bursal disease hidden peak period. From the physical sense, 28 days old chicken bursa and spleen size should be the same, if less than 30 days old chicken bursa spleen, indicating previously occurred infectious bursal disease (recessive disease), The Newcastle disease epidemic in the second period, Guchang avoid poor results caused by Newcastle disease two or invalid. Infectious bursal disease sooner, the more heavy immunosuppression, especially before the onset of 21 days will result in permanent immunosuppression, which is about 30 days old Newcastle-prone one of the important reasons.
Immunosuppressive diseases in addition to their own death or poor growth caused by the economic losses, more importantly, will lead to the occurrence of other infectious diseases, such as failure or other infectious diseases, immune pathogenicity enhancement, therefore, control of autoimmune disease reduce or eliminate the occurrence of the primary measures of other diseases.
Second, virus diseases will remain a major threat to poultry disease
The occurrence of avian viral diseases more and more serious, will remain a major threat to poultry disease, 25 to 45 days if the chicken disease, most of the virus infection, and is the major source of disease, but often show E. coli disease or chronic respiratory disease. Chicken of the stage of diagnosis must be with the idea of viral diseases, not to be the surface of E. coli or confused by chronic respiratory disease, and control the type of poultry disease, mainly to follow the control of viral diseases, treatment of E. coli supplemented by the principles of medication or mycoplasma. Because the virus has caused serious damage on the body, so that serious low immunity, the virus will take the opportunity to invade, so treatment is difficult, if complete cure viral diseases, bacterial diseases will be much more relaxed up.
Third, the phenomenon of Avian flu will be extremely popular mixed
Looking at the current poultry disease, mostly in the form of mixed infections, particularly in the broiler outstanding performance in the future, this phenomenon will be most common. In the clinical diagnosis and treatment process, should not see when the autopsy the typical stall-coli disease diagnosed immediately, rather than pay attention to other diseases, so often misdiagnosed.
As conditions of pathogenic E. coli is often complicated by other infectious diseases and secondary infections, if not distinguish primary disease, there would be a good therapeutic effect, such as renal mass support, mixed mycoplasma and E. coli infection In the early onset E. coli were first mycoplasma disease, Mycoplasma make Chicken and upper respiratory tract mucosa is damaged, to create the conditions for secondary E. coli, whereas the renal mass support has resulted in the infection of chicken body watery diarrhea, intestinal upset pH and microflora balance, and thus secondary to the E. coli disease, according to the writer's experience, most are infected with Mycoplasma disease of renal mass support and only 4 to 5 days caused by E. coli secondary, address this situation, to prevent secondary infection The best way is in the case of renal mass support, the vote on the E. coli disease preventive medicine.
Treatment of mixed infections to be overall consideration, careful analysis to judge which diseases caused by or complicated by secondary infection, not a loss, medication must be taken into account, we must follow the principle of combining Chinese and Western, if necessary, sensitivity test, select highly sensitive to drugs, and attention through kidney and kidney, nourish the liver and gallbladder, to achieve the objective cure.
Fourth, the performance will become increasingly complex Avian
Avian's performance will become increasingly complex, such as Newcastle's new genotype Ⅶ increasingly popular wide; super type bursal, bursal strain variation, the emergence of infectious bursal recessive, so that infectious bursal disease uncertain.
Such as infectious bursal disease in clinical practice significantly wider age, disease duration longer occur as early as 3 days old You Qin, no later than 300 days of laying hens have occurred, and the host group is also broadening, in addition to chicken, the duck, geese, pigeons have become a natural reservoir of bursal disease, and ducks also showed significant clinical symptoms.
Newcastle disease in chickens in the immune pathogenesis of good, and quickly spread to the whole group, the old genotype-I, VI type, VIII type still exists, the increasingly popular wide range of new genotypes to disease prevention more difficult. Virulence to the polarization, atypical type of virulent Newcastle disease Newcastle disease and showed multiple trends, mild strain of bird flu still prevalent, and other bacterial diseases simultaneously.
As time goes by, new kinds of poultry disease also appear, of veterinary surgeons to be able to workers in complex situations with flexibility Fenxi, correct judgments, integrated Kaolv, which Yaoqiu veterinary workers, not dogma, to live Xue utilizing poultry disease theory, must be a new vision and ideas to study the changes in the poultry disease.
