As poultry companies weigh cost and efficiency with higher animal welfare standards, research comparing conventional and slow-growing broiler breeds showed that the slow-growing chickens displayed behaviors more closely associated with positive welfare.
University of Georgia researchers, led by Maricarmen Garcia, PhD, have developed a new genotyping assay for analyzing clinical samples of infectious laryngotracheitis virus (ILTV). Identifying the genotype of the outbreak-related virus and determining its genetic relationship to field or vaccine strains is key to diagnosing ILTV.
Two direct-fed microbials (DFMs) have shown promise in reducing health problems associated with Enterococcus cecorum in broilers.
Enteritidis is one of the most common serotypes of Salmonella globally and is historically associated with poultry. Unfortunately, antibiotic resistance is making it more challenging to treat.
Mobility and leg problems are common in modern-day broilers, which are bred for high breast-muscle yield. Extra activity can help the birds support the extra bodyweight and prevent skeletal disorders. Could colored lighting encourage broilers to be more active and less prone to leg problems?
Kansas State University research has offered a glimpse into the potential of niacin supplementation in broiler diets — but questions remain about the exact benefits producers might expect from such a move.
Using a dietary supplement containing a blend of Bacillus bacterial strains appears to positively affect the intestinal health and immunity of broiler chicks after a coccidia challenge, according to a Frontiers in Microbiology report.
A survey of more than 600 Enterococcus samples from Mississippi poultry farms revealed that E. cecorum primarily affects broilers, while E. faecalis is more problematic in hatcheries and very young chicks.

Having been linked to everything from yield gains, feed-conversion ratio and immunity to disease tolerance, mortality and animal welfare, intestinal health is foundational to the success of poultry operations today. Three poultry-health experts took part in an intestinal health webinar in which they discussed viral, bacterial and coccidial challenges in poultry, their impact on gut health and potential management strategies.
