Production and Flock Health Management


Rapid and effective disease monitoring and control programs are important to ensure that poultry farms will have a good performance. However, poultry diseases that are normally encountered in the field are almost always complicated. Manifestations of diseases in actual field conditions are very different from typical symptoms that are described in “textbooks”. In addition, the antibody titers of poultry flocks are always influenced by vaccination programs. As a result, diagnosis based on antibody titers of selected pathogens alone is hardly effective.


To solve these limitations, PPQC routinely performs sequential serological investigations to screen the antibody titer of all the flocks of its client farms against major infectious poultry diseases such Newcastle Disease, Infectious Bronchitis, Infectious Bursal Disease, Mareks Disease, Mycoplasma gallisepticum, Mycoplasma synoviae, Infectious Coryza and Egg-Drop Syndrome continuously. Database on serial antibody data can effectively differentiate whether changes in antibody titers are a result of vaccination or a consequence of ongoing field infection. This method can provide a more sensitive and real assessment of health and disease conditions of poultry flocks.


In addition, especially in complicated cases that cannot be diagnose by routine serological tests alone, microbiological isolation and characterization studies, virus isolation, immunopathological and epidemiological studies, and molecular and genetic sequencing (PCR, qRT-PCR, PFG, DNA sequencing ) techniques are always conducted to ensure that diseases are diagnosed properly. Accurate and rapid diagnosis is important so that effective control programs can be implemented quickly to minimize the economic impact of any diseases in the production performance of our client farms .
