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....
Sambucus nigra Extracts Inhibit Infectious Bronchitis Virus at an Early Point during Replication
Sambucus nigra (common elderberry) extract was found in an in-vitro studies in the US to inhibit the Infectious Bronchitis virus at an early point in infection....
Spatial and Temporal Analysis of Microbial Populations in Production Broiler House Litter in the SE United States
While Clostridium perfringens, Staphylococcus spp. and Enterococcus spp. were consistently present in the litter, foodborne and poultry pathogen levels were difficult to predict, according to new research from Mississippi....
Immune Responses to Eimeria tenella Sporozoite Protein as Vaccine to Broiler against Coccidiosis
A new study from Syria found two types of immune responses, humoral and cellular immune responses to sporozoite antigen which conferred effective protection to broilers against one of the pathogens causing coccidiosis....
New Vaccine to Protect Against Two Important Poultry Diseases
North Carolina State University scientists have achieved a biological characterisation of a serotype 1 Marek's disease virus-vectored bi-valent vaccine for infectious laryngotracheitis and Marek's disease....
Assessing the Risk of Highly Pathogenic Avian Influenza H5N1 Transmission through Poultry Movements in Bali, Indonesia
An international group of researchers has found that live poultry movements play in transmitting the H5N1 avian flu virus in Indonesia, and that a variety of control measures is necessary to reduce disease spread....
Spray Application of Live Attenuated Mycoplasma Gallisepticum Vaccines
Both of the Mycoplasma gallisepticum live attenuated vaccines tested in pullets in this work in Mississippi were equally effective when applied by spray application. The researchers remarked that the dosages required for a consistent response were higher...
Influence of Dietary Calcium and Phytase on Bird Performance during a Natural Necrotic Enteritis Episode
A new study reveals that higher dietary calcium had negative effects on mortality associated with necrotic enteritis in broilers and on their performance. Calcium source and phytase supplementation also affected performance, gizzard pH and the digestibility...
