Over the past decades, the poultry sector’s growth and trends towards intensification and concentration have given rise to a number of environmental concerns. A direct consequence of these structural changes (industrialization, geographical concentration and intensification) in poultry production is that far more waste than can be managed by land disposal is produced, resulting in environmental...

The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environm...

The importance of poultry production worldwide is underscored by this statistic: poultry meat represents almost one-third of meat produced and consumed globally. Moreover, egg production, on a weight basis, is almost 80% that of poultry meat production. This was addressed in a previous editorial (Scanes, 2007b). The basis for the increasing importance of poultry worldwide has been research on g...

The poultry industry in the United States faces numerous challenges that both directly and indirectly impact the sustainability of the nation’s poultry production systems. The intensive selection for fast growth and high feed efficiency in modern-day birds has been accompanied by a weakened immune system, increased disease susceptibility and dependence on in-feed antibiotics.

BACKGROUND Poultry represents an important sector in animal production, with backyard flocks representing a huge majority, especially in the developing countries. In these countries, villagers raise poultry to meet household food demands and as additional sources of incomes.

The challenges and targets facing the world's poultry science community in the immediate future are reviewed in the context of meeting the dietary needs for animal protein of the world population. The prior need to provide for the increasing demand for cereals, oil seeds, and grain legumes for human consumption is assessed at having a reasonable chance of success. If this need is met, the requi...

From 1948 to 1988, there were 6 confirmed foodborne disease outbreaks in the U.S. transmitted with domestically produced hard cheeses as the food vehicle. Various research reports have raised concerns about the public health protection provided by the current 60-day aging period in the manufacture of hard cheeses made with unpasteurized milk. The objective of this study was to investigate the a...
