Immune function differs in Marek’s resistant chickens

Photo: The Pirbright Institute. In new research that could pave the way for the development of more effective vaccines against Marek's disease, researchers with The Pirbright Institute in the U.K. have identified key immune response differences in chickens resistant to the disease. In a recent paper published in Frontiers in Immunology, the researchers showed how … Continue reading Immune function differs in Marek’s resistant chickens

In brief: HPAI; offshore mussels, cattle efficiency, trout

Highly pathogenic avian influenza (HPAI) cases continue to rampage across the country, though numbers so far in October is lower than in September. So far in October, as of Oct. 22, almost 833,000 birds were culled, including more than 527,000 turkeys, with a significant number of backyard flocks affected, particularly in the West, but backyard … Continue reading In brief: HPAI; offshore mussels, cattle efficiency, trout

Artificial intelligence helps mitigate poultry heat stress

Photo by Alexas Fotos on Pexels.com It gets hot in Georgia, making heat stress a major issue for the state's significant broiler chicken industry. Chickens are raised on thousands of farms in Georgia and across the southeastern U.S., and those birds need to be transported to processing facilities when they reach market size. Transportation stress, … Continue reading Artificial intelligence helps mitigate poultry heat stress

Novel imaging method to assess bone strength in hens

Photo by Rachel Vine on Pexels.com Laying hens are at risk of bone fractures due to biological changes linked with egg production. A novel method developed by The Roslin Institute in the U.K. enables poultry breeders to consider bone density in laying hen selection, which would allow greater bird health and welfare. Strong bones offer … Continue reading Novel imaging method to assess bone strength in hens

IBV replication temperature sensitive, could aid vaccine development

Photo by Leonardo Jarro on Pexels.com Infectious bronchitis virus (IBV), a highly contagious coronavirus in poultry, causes respiratory symptoms and affects the reproductive tracts of birds, making it a significant economic and welfare concern for the global poultry industry, according to The Pirbright Institute in the U.K. Pirbright researchers have been investigating potential vaccines against … Continue reading IBV replication temperature sensitive, could aid vaccine development

Barnyard Roundup: Cooling cattle, COVID-hyperimmunized eggs

Photo by Kat Smith on Pexels.com Nationwide, heat stress causes $300 million in losses to cattle, and heat stress is exerting its effects across a broader geography for a longer duration each year. Now, University of Florida scientists are seeking to understand the effects of heat stress on grazing beef cattle. The effort will be … Continue reading Barnyard Roundup: Cooling cattle, COVID-hyperimmunized eggs

Virus-resistant poultry research gains traction

Photo by Rachel Vine on Pexels.com Past research studies have explored the potential for using animal genetics to develop livestock and poultry that are naturally resistant to disease. A new study from the Roslin Institute in the U.K. suggests specific genetic variations that determine birds' responses to infection. The Roslin researchers analyzed DNA from chickens … Continue reading Virus-resistant poultry research gains traction
