Since the first outbreak of highly pathogenic avian influenza (HPAI - H5N8 type) on January 16, 2014, about 14 million poultry birds, including layers and ducks, were culled until the last outbreak on July 28, 2014. Of the total culled birds, about 3.4 million were broilers and about 10 million were layers. However, the unparalleled long-lasting HPAI outbreak did not have any significant impact on chicken production due to 1) the culled broiler numbers only accounted for 0.4 percent of annual slaughtered chicken numbers in 2013; and 2) a reduced mortality rate in broiler chicks during the summer season because of favorable weather; and 3) increased PS inventory throughout 2014.
