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.
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.
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.
Waste byproducts from rearing insects commercially could play a role as a sustainable broiler feed, the results of research presented at the 2024 International Poultry Scientific Forum suggest.
Continuous lighting is commonplace in commercial broiler houses, but is that what’s best for the birds?
The move to cage-free egg production in the US and Europe created a seismic change in hen breeding programs.
Histomoniasis is nothing new to turkey producers, yet treatment options remain a major challenge. Bans of therapeutic and prophylactic compounds in several countries in recent years have only added to outbreak risks, emphasizing the need for alternative control strategies.
The ability to process birds on farms and eliminate live transport offers some compelling benefits to the poultry industry whose customers are increasingly disconnected from animal agriculture.

The chicken carcass is the broiler industry’s final product, but a range of issues can affect its quality and, ultimately, the amount of edible food available for consumers. For producers, there are a variety of ways to manage outcomes, says an industry expert — starting with the earliest stages of birds’ lives.
Dried distillery yeast can be used as a source of energy and protein in broiler diets, but producers should pay attention to inclusion rates to avoid affecting feed conversion and potentially disrupting the birds’ gut microbiome.
Modern Poultry has appointed JoAnna Pendergrass, DVM, as its managing editor.
