Adnan Ali Khalaf Alrubaye, PhD, University of Arkansas, and his research team conducted a research project that aimed to achieve lameness reduction in broiler chickens via in ovo immunization with an eBeam-treated multi-strain Staphylococcus vaccine.
Controlling ILT with vaccination is critical in maintaining healthy and profitable poultry production. Nearly all long-lived poultry in the US are vaccinated against ILT.
Providing chicks a dark period from the time of placement in the broiler house is practical and affordable for broiler producers and has no apparent negative effects on broiler performance, according to research conducted by Garret Ashabranner, PhD; Brian Fairchild, PhD; and Michael Czarick, engineer at the University of Georgia.
A risk-assessment model for Salmonella demonstrates the potential public health benefit of focusing on chicken parts that are heavily contaminated with highly virulent serotypes of this bacteria instead of focusing on low-virulent serotype.
A multistate salmonella outbreak in the US due to the consumption of contaminated turkey products spurred a joint effort between the Centers for Disease Control and the turkey industry to identify an untraditional serotype of Salmonella, S. enterica serotype Reading (S. Reading).
Formaldehyde fumigation is a conventional method used to control total environmental microbial counts in the hatchery. However, according to Christine N. Vuong, PhD, University of Arkansas, this method does not differentiate between beneficial or pathogenic microbes.
Bird welfare is improved in cage-free layer systems compared to cage systems, but indoor air quality suffers in a cage-free environment due to higher bird activity.
Updated research supported by the US Poultry & Egg Association quantifying the US poultry industry’s on-farm antibiotic use shows further improvements in antibiotic stewardship and commitment to disease prevention within poultry production.
Multi-stage egg-incubation systems are challenging to manage. And too often, attempts to keep late-stage embryos from overheating create situations where early-stage embryos are at sub-optimal temperatures during critical developmental periods.
Hatchery sanitation is a continual issue in commercial poultry and has become a focus since the removal of antibiotics in production, according to Brian Jordan, PhD, associate professor at the University of Georgia.
In this age of “no antibiotics ever” farming, the re-emerging necrotic enteritis (NE) disease caused by Clostridium perfringens poses a major economically important health concern in poultry, particularly in broiler flocks, says Ravi Kulkarni, BVSc, assistant professor at North Carolina State University.
Light intensity has been shown to affect the activity of birds, but most studies have focused on constant light intensities to determine their effect on welfare.
