New research by Callie McQuain, DVM, veterinarian and grad student at the University of Georgia, substantiates anecdotal field experience indicating that Eimeria maxima is the type of coccidia that...

... New Marek’s test helps ensure successful vaccination, biosecurity

A new test is helping producers in Europe better protect their flocks against Marek’s disease (MD).

... E. maxima linked to mortality in broilers vaccinated for coccidiosis

Eimeria maxima in broilers vaccinated against coccidiosis appears to be an important cause of mortality, according to the preliminary results of a study presented at the 2017 annual meeting of the...

... Optimizing diets could limit foot pad dermatitis outbreaks

Managing diets to improve litter quality could help limit incidence of foot pad dermatitis (FPD) in broiler chickens and turkeys, scientists say.

... E. coli vaccine reduced colibacillosis lesions and mortality in turkeys

A modified-live Escherichia coli vaccine for turkeys was demonstrated to be safe and effectively reduced the incidence of lesions and mortality due to colibacillosis, according to recent studies.

... Early feeding, housing may affect broiler response to immune challenges

Early feeding after hatch and the housing type can affect the response of broilers to immune challenges later in life, indicates a study from the Netherlands.

... Are there practical alternatives to ionophores?

Proponents of raising broilers without ionophores and other antibiotics have proposed putting more emphasis on farm management, biosecurity and alternatives to anticoccidials.

... Hens in enriched colony system appear more stressed, flighty

Hens in an enriched colony system were more stressed and flighty than conventionally caged birds in a study from Mississippi State and Texas A&M Universities.

... S. enteritidis shedding more frequent among hens in conventional cages

Fecal shedding of Salmonella enteritidis was significantly more frequent among experimentally infected laying hens in conventional cages compared to hens housed in enriched colony cages, indicates a...

... Broiler study shows challenges and potential of drug-free production

Broilers raised in a drug-free program had a higher feed-conversion ratio (FCR), decreased mean daily weight and decreased mean live marketing weight despite administration of antibiotic

... IBD V877 vaccine can break through maternal antibodies

A live infectious bursal disease (IBD) vaccine based on the V877 strain can override maternal antibodies, doesn’t revert to virulence and has limited interactions with other live vaccines.

... Canada studies find no links between ionophores, resistance of other antibiotics

One of the few studies about antibiotic resistance and ionophores in poultry was published by Canadian researchers in 2007 who found that isolates showing resistance to multiple antibiotics can be...

... High stocking density predisposes broilers to NE

High stocking density has adverse effects on broiler welfare and intestinal health and predisposes the birds to necrotic enteritis (NE), according to the results of an experiment conducted by...

... Reducing false positives pays in ELISA mycoplasma testing

Poultry producers should consider specificity when selecting a Mycoplasma ELISA test to avoid costs associated with false positives.

... What’s causing ‘woody breast’ in poultry?

A condition known as “woody breast” is puzzling US poultry scientists investigating why breast-muscle tissue from some broiler flocks is hard and tough instead of tender and juicy.

... Experience with GA 08 provides valuable information about IBV variants in poultry

Experience with Georgia 2008 (GA 08) — the infectious bronchitis variant that’s caused major economic losses for poultry producers in the Southeast — has provided valuable information that will...
