Varying periods of light and dark can affect turkeys’ health and well-being, including their eye health, level of fearfulness and mortality, according to a study led by Allison Pullin, PhD, animal welfare professor at North Carolina State University.
Gangrenous dermatitis is a major commercial turkey-production disease, causing significant economic losses annually from increased bird deaths and condemnations at the processing plant. Can a litter amendment impact the spread of this bacteria?
Ceva Animal Health has started antigen production for an experimental autogenous vaccine to fight the emerging avian metapneumovirus (aMPV) disease.
Finding the right balance of economics and growth performance is key when developing turkey poult diets. Limiting the metabolizable energy content is one way to reduce costs, but that can also reduce the young birds’ growth potential. Lysophospholipid supplementation could be the answer.
With a price tag of over $1 billion for indemnity payments, the current outbreak of highly pathogenic avian influenza (HPAI) is expensive. Is premise depopulation still the way to manage HPAI?
A Midwestern flock of 15,000 finisher turkey hens experienced persistent respiratory disease that caused 10% to 15% mortalities, prompting the flock veterinarian to determine the cause of this heavy mortality.
Virtually everyone in the poultry industry is aware of coccidiosis — a disease caused by protozoan parasites, Eimeria, that develop within the intestine of most domestic and wild animals and birds. The condition is more elusive in turkeys, however.
Alternative lighting strategies that allow hens additional feeding opportunities during scotophase, or dark periods, can go a long way toward improving egg quality and bird welfare.

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).
USDA’s Center for Veterinary Biologics has granted Huvepharma a conditional license for the manufacturing and sale of a new turkey coccidiosis vaccine.
