Most poultry producers today use vaccines to help manage coccidiosis. Live coccidial vaccines are designed to uniformly infect birds with a controlled number of Eimeria oocysts to stimulate a protective immune response, but not all vaccines are the same.
Veterinary data play a critical role in not only analyzing poultry health but also implementing long- and short-term strategies to improve health and prevent disease. However, several challenges present roadblocks to capturing and interpreting these data.
Researchers investigating combinations of plant-derived ingredients observed a positive impact of a specific phytogenic feed additive when looking at production performance and meat quality in broilers — with particularly notable results for larger birds.
Poultry farms seeking protection against infectious laryngotracheitis (ILT) outbreaks may find the best defense for layers and broiler-breeder replacement birds is a dual ILT vaccination program.
As poultry companies continue to increase their oversight of products in response to tightening margins, suppliers are under greater pressure to provide third-party data demonstrating product efficacy.
Animal welfare audits are performed to evaluate whether a hatchery, farm, or processing plant is meeting the specific animal welfare standards of a certification program.
Prolonged exposure to heat stress can lead to respiratory injury in broiler chickens, according to a recent study in China.
Using the antibiotic bacitracin in poultry poses virtually no risk of an untreatable human infection from antimicrobial-resistant bacteria originating from chicken and turkey products, reports Randall Singer, DVM, PhD, University of Minnesota.
Feeding broilers a high dose of a bacterial 6-phytase alongside a xylanase-glucanase enzyme combination resulted in performance improvements and cost savings, in a field study.
Turkeys are seasonal breeders, meaning exposure to a long-day photoperiod triggers the reproductive response. The challenge is that the photoreceptors are deep within the brain. The light must therefore penetrate the skull and brain tissue to elicit a response.
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).
Breeding birds for efficient cage-free production requires developing healthy hens that lay an egg every day for 100 weeks and possibly up to 200 weeks in the future, reported Sijne Van der Beek, PhD, chief technology officer, Lohmann Breeders, The Netherlands.
