The efficacy of various carbohydrate-based cocktails in reducing the number of enteropathogens in the crops of broilers subjected to feed withdrawal was examined. Market-aged broilers that had been orally challenged with Salmonella typhimurium were provided the cocktails during a 12-h feed withdrawal. After feed withdrawal, the broilers were processed, and their crops were aseptically removed a...

The North American pork production industry is heavily dependent on relatively few feed ingredients, including the cereal grains (corn, wheat, and barley), oilseed meals (soybean meal) and industry co-products (DDGS). As such, factors that impact the quality of these feed ingredients can pose serious challenges relative to the formulation of pig diets. One such factor that impacts the quality o...

Background and scope Genetically Engineered (GE) crops have been the most rapidly adopted agricultural technology in mankind history, as evidenced by a 100-fold increase from 1.7 to 181.5 million hectares globally cultivated between 1996 and 2014 1. Their environmental and economic benefits for farmers, farm workers, and society have been extensively reported elsewhere 2,3. Although GE crops ar...

The broiler crop has recently been implicated as a major source of Salmonella contamination at commercial processing. Furthermore, feed withdrawal has been positively correlated with increased Salmonella incidence in the crop, probably due to coprophagy. In the present study, a rapid screening assay was developed to evaluate several potential disinfectants in the presence of large quantities of...

A lower price on poultry meat, compared with other meats (beef, pork etc.), affects the increasing demand for poultry meat. The productivity and production cost of broiler chickens are directly related to the amount of feed fed, the proportion of crude protein in the feed, and the biological value and price of the feed. The EU produces only 30% of the protein crops used for feed; thus, the larg...

Industrial or “Green Revolution” agriculture depends upon petroleum to manufacture and spread fertilizers, pesticides and herbicides and to power irrigation systems that act upon crops selected to increase agricultural yield. It has been criticized on the grounds that it has favored mainly rich farmers and caused serious environmental pollution. Now a second “Green Revolution” is being proposed...

Globally, food-producing animals consume 70 to 90% of genetically engineered (GE) crop biomass. This review briefly summarizes the scientific literature on performance and health of animals consuming feed containing GE ingredients and composition of products derived from them. It also discusses the field experience of feeding GE feed sources to commercial livestock populations and summarizes th...

Increasingly more studies are raising concerns about the increasing consumption of meat and the increasing amount of crops (cereals and oilseeds in particular) used to feed animals and that could be used to feed people. The evolution of this amount is very sensitive to human diets and to the productivity of feed. This article provides a 2050 foresight on the necessary increase in crop productio...

In 2008, the world produced approximately 87 gigaliters of liquid biofuels, which is roughly equal to the volume of liquid fuel consumed by Germany that year. Essentially, all of this biofuel was produced from crops developed for food production, raising concerns about the net energy and greenhouse gas effects and potential competition between use of land for production of fuels, food, animal f...
