BACKGROUND Health education to reduce population poultry exposures has limited effect. Lay beliefs about H5N1 highly pathogenic avian influenza (HPAI) causes could provide insights helpful for improving public health interventions. METHODS Qualitative interviews of poultry farmers, retailers, market stall holders and consumers in Hong Kong (n = 20), Guangzhou (n = 25), Vietnam (n = 38) and Th...
Genetic selection of broilers for rapid growth has resulted in greater final BW and improved feed conversion efficiency in reduced time increments. However, accelerated growth rates are associated with several undesirable traits, including increased fat deposition, and higher incidence of metabolic diseases, visual anomalies, skeletal deformities, and circulatory problems. These deficiencies, a...
There have been three influenza pandemics since the 1900s, of which the 1919-1919 flu pandemic had the highest mortality rates. The influenza virus infects both humans and birds, and mutates using two mechanisms: antigenic drift and antigenic shift. Currently, the H5N1 avian flu virus is limited to outbreaks among poultry and persons in direct contact to infected poultry, but the mortality rate...
While rearing birds in confinement and at high density are very successful practices for producing poultry meat and eggs, these conditions may promote the spread of infectious diseases. Consequently, the poultry industry places greatemphasis on disease control measures, primarily at the animal husbandry level. The field of genomics offers great promise to complement these current control measur...
Poultry production is the most rapidly expanding agricultural industry. Consumer awareness of animal welfare has grown in recent years, and as a result, consideration for higher-quality meat increased. Environmental changes impact activity, including poultry production. These have raised serious worries that will severely health productivity due to climate change. In light current environmental...
Despite stringent biosecurity measures, infections by bacterial food pathogens such as Campylobacter are a recurrent problem in industrial poultry houses. As the main transmission route remains unclear, persistence of these infections has been linked to bacterial survival and possibly multiplication within protozoan vectors. To date, however, virtually no information is available on the diversi...

1. Feather pecking is one of the major problems facing the egg industry in non-cage systems and is set to become even more of an issue with the European Union ban on the keeping of laying hens in barren battery cages which comes into force in 2012 and the prospect of a ban on beak-trimming. Reducing feather pecking without resorting to beak treatment is an important goal for the poultry industr...
