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.
Careful attention to the coccidiosis vaccination process and follow-up monitoring will go a long way toward ensuring a positive outcome. However, even the best programs will encounter an occasional hiccup.
A postbiotic product proven to reduce the severity of avian pathogenic Escherichia coli (APEC) in broilers could give producers and veterinarians an additional tool to manage risk in pre-harvest poultry.
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.
A novel automated gel-beadlet system for vaccinating chicks proved successful in providing uniform coverage against coccidiosis.
A successful coccidiosis-vaccination program starts with proper vaccine handling and uniform application at the hatchery. Charlie Broussard, DVM, Merck Animal Health, offers several areas to monitor to determine whether the vaccination program is on track to protect the flock.

Getting chicks off to a quick start in the brooder house is always a priority, but it is especially critical when birds have been vaccinated for coccidiosis.

Avian metapneumovirus (aMPV) has swept through production facilities across the US since its initial appearance in late 2023. aMPV infections can result in mass morbidity, significant egg drops and, in the most severe cases, mortalities.
Virtually everyone involved with live poultry production knows the importance of protecting layer, breeder and broiler flocks against infectious bursal disease. If left unchecked, it can cause listlessness, watery diarrhea, ruffled feathers and dehydration.
