Most livestock and poultry odors are generated by the anaerobic decomposition of livestock wastes such as manure (feces and urine), spilled feed, bedding materials, and wash water. Increased organic loading rates due to expanding animal numbers, slug loading, concentrated waste streams, and/or inadequate amounts of dilution water increase the potential for odor emissions from waste management s...

Domestic animal husbandry, a common practice globally, can lead to zoonotic transmission of enteric pathogens. However, this risk has received little attention to date. This systematic review and meta-analysis examines the evidence for an association between domestic exposure to food-producing animals and cases of human diarrhea and specific enteric infections. We performed a systematic review ...

Colistin resistance was investigated in 1,696 isolates collected from 2007 to 2014 within the frame of the French livestock antimicrobial resistance surveillance programme. The mcr-1 gene was detected in all commensal Escherichia coli isolates with a minimum inhibitory concentration to colistin above the 2 mg/L cut-off value (n=23). In poultry, mcr-1 prevalence was 5.9% in turkeys and 1.8% in b...

Core body temperature is an important measure of animal thermal stress and thermoregulation. A shortrange telemetry system was evaluated in poultry, beef, and dairy cattle. This system provides good temperature accuracy, excellent temperature resolution, and adequate response time. However, this system would need some improvement before it could be implemented into the livestock industry.

The industrialization of livestock production and the widespread use of nontherapeutic antimicrobial growth promotants has intensified the risk for the emergence of new, more virulent, or more resistant microorganisms. These have reduced the effectiveness of several classes of antibiotics for treating infections in humans and livestock. Recent outbreaks of virulent strains of influenza have ari...

Across the United States and abroad, innovative producers, processors, trade organizations and others in the agricultural sector are exploring the promise of Environmental Management Systems (EMS) to improve their environmental and business performance. An Environmental Management System or EMS helps farmers develop their own, personal strategies for reducing environmental risk on their operati...

Increased production of corn based ethanol and the resulting increase in availability of distillers dried grain with solubles (DDGS) has a number of implications for the U.S. livestock industry and for the production of traditional livestock feed crops. Some of those implications are examined here. First, and most importantly, the potential size of the domestic market for DDGS is evaluated in d...
