Reducing Losses from Blackhead Disease
New research from the University of Georgia reveals that chicken litter may pose a risk of transmitting blackhead to turkey flocks, while their work to vaccinate birds against the disease was unsuccessful....
Bone Characteristics and Femoral Strength in Commercial Tom Turkeys
Reducing the energy and protein levels in the diet of male turkeys to 60 per cent of NRC recommendations improved both the strength and quality of the leg bones in a Michigan State University experiment. Bone length and ash content were not different...
Incidence of Gastrocnemius Tendon Rupture in Broilers
More tendon ruptures were observed in broilers reared during cooler months in this US trial, which the researchers attributed to the use of a growth promoter resulting in heavier bodyweights....
Studies Demonstrate Benefits of Dual-needle in-ovo Vaccination for Marek’s Disease
In a new study, broiler chickens vaccinated in ovo with a dual-needle delivery system were better protected from Marek’s disease than those receiving the same vaccine with a conventional single-needle system, according to Dr Taylor Barbosa of Zoetis....

Milestones in Avian Coccidiosis Research: A Review
This article, by Professor David Chapman of the University of Arkansas, describes some of the milestones in research concerned with protozoan parasites of the genus Eimeria that infect birds and cause the disease coccidiosis....
Government Interference in Poultry Disease Eradication: Avian Flu in Mexico
Low-pathogenic avian flu in Mexico represents a direct cost to the local poultry industry of US$246 million annually over the last 18 years, or a cumulative $4.4 billion, according to Armando Mirandé, DVM, MPVM, MAM, ACPV. He outlines how these costs...
Different Sources of Dietary Zinc for Broilers Subjected to Immunological, Nutritional and Environmental Challenge
Research from Brazil reveals that zinc (from an organic or inorganic source) can be fed to broilers at less than 100ppm without affecting humoral immunity, zinc concentration in the carcass or bird performance. At the same level of zinc, the organic source...
Clostridium perfringens in Poultry Feed Ingredients and Control with Chemical Treatments
The pathogen that causes necrotic enteritis in broilers, Clostridium perfringens, was found in 60 per cent of feed samples in Brazil, where researchers found that some chemical treatments were effective in reducing contamination. ...
Characterisation of Eimeria in Australia
Coccidiosis in Australia is widespread, species are ubiquitous, dynamic and genetically diverse, and this diversity does not appear to be geographically structured, according to new research from the University of Queensland reported by Poultry CRC....
Collaborative Studies on Cyanosis in Broiler Breeders
New research at Mississippi State University has increased understanding on cyanosis, a blue or purple colour of the skin in broiler breeders. They found differences in heart function between the three genetic lines they studied and a lower incidence...
Vocalisation Study Provides Insight into the Well-being of Birds in Grow-out Houses
Sensors capable of reliably monitoring the well-being of birds reared in confined housing currently do not exist but researchers from Georgia Tech Research Institute are making progress on using the noises made by broilers to indicate health or welfare...
Studies on Newly Emerging Reassortant Very Virulent Infectious Bursal Disease Viruses
Current breeder vaccination programmes may not adequately protect birds against the more recent very virulent strains of infectious bursal disease virus (IBDV), concludes an Ohio State University researcher from a new study....
