Artificial turf outperformed wood shavings in mitigating ammonia and dust in cage-free layer rooms

sspiegel0120@gmail.com on August 27, 2025

Cage-free, egg-layer producers regularly face the challenge of managing high ammonia and dust levels within production houses, of which manure and bedding are the main contributors. A Purdue University research team led by Ji-Qin Ni, PhD, assistant professor in the agricultural and biological engineering department, sought to investigate artificial turf as a flooring option to address such pollutants.

Unwanted roosters: Is in-ovo sexing the answer?

sspiegel0120@gmail.com on August 26, 2025

For every laying hen that is hatched, approximately one male counterpart also hatches. However, as roosters do not produce eggs, they are typically culled, or euthanized, at hatch. However, the culling of these day-old male chicks raises ethical concerns.

Using technology to address the triple threat of dust in poultry houses

Questions remain around the transmission of highly pathogenic avian influenza into and within poultry houses, but the infectious nature of the virus is its biggest weapon, according to a USDA expert.

IBV types in the Americas and the next threat to commercial poultry in the US

sspiegel0120@gmail.com on August 18, 2025

Controlling IBV through vaccination requires knowledge of the circulating field strains. For this reason, surveillance is critical. Mark W. Jackwood, PhD, and Jose Linares, DVM, describe Ceva’s Scientific Support and Investigation Unit that uses real-time quantitative RT-PCR panels to rapidly detect multiple IBV types.

Technology will direct future advancements in animal welfare and productivity

sspiegel0120@gmail.com on August 18, 2025

Technology is part of everyday life in a poultry house, and it has helped the industry achieve production goals efficiently, sustainably and with more speed than imagined. But with these technological advances, animal agriculture is on the cusp of a major change.

Questions remain as search continues for solutions to emerging bacterial threat

sspiegel0120@gmail.com on August 18, 2025

Enterococcus cecorum was first reported in the US in 2009. Disease caused by this pathogen poses considerable welfare and economic challenges for broiler producers and currently has no effective antibiotic-free treatment. For the past 15 years, Mitsu Suyemoto, research specialist at North Carolina State University, has conducting pioneering research on this emerging pathogen with Luke Borst, DVM, PhD. Of note, their team developed many of the key assays used to study E. cecorum today.

NC State researcher: Autofluorescence accurately evaluates Eimeria oocyst viability

sspiegel0120@gmail.com on August 12, 2025

Research led by Phillip Yeboah, PhD candidate at North Carolina State University examined autofluorescence as a method for determining whether Eimeria oocysts are viable and capable of causing infection.

Organic acids have little effect as a Salmonella intervention in broiler study

sspiegel0120@gmail.com on August 12, 2025

Adding organic acids to poultry drinking water has been suggested as a potential intervention in managing Salmonella, but research by Auburn University scientists showed otherwise.

How immunosuppression and secondary pathogens increase aMPV threat to US poultry

sspiegel0120@gmail.com on August 11, 2025

The emergence of aMPV subtypes A and B has left US poultry producers seeking new tools to reduce the economic impact of this disease. In an interview, Silke Rautenschlein, PhD, professor at the University of Veterinary Medicine in Hannover, Germany, covers the past, present and future of the virus and its control.
