When chickens are healthy they consume less feed and produce more quality eggs. They are less trouble to look after and less money is spent on medical costs. Poultry disease can spread rapidly among chickens because they are usually kept together in the chicken house. The chickens share the same feeders and drinkers, which can spread disease and infections rapidly from sick to healthy chickens. In intensive egg production systems, much focus is placed on the egg laying performance of the flock. Poultry diseases can negatively affect the health and performance of your flock. Important and common poultry diseases include necrotic enteritis, chronic respiratory diseases, gangrenous dermatitis, fowl cholera, and avian influenza.
Since contaminated water can transmit serious diseases to birds, poultry owners should always provide good quality water for their flocks. “We know that avian influenza can be spread through water that wild ducks have been on,” says Gerald Hauer, assistant chief provincial veterinarian. “Most people know to keep their poultry away from dugouts and ponds, but we want to remind them to treat that water before they let their birds drink it.” To determine...
The intestinal welfare is a crucial parameter in animal production, changes in the welfare cause disbiosis (bacterial enteritis, enteritis non-specific, bacterial overgrowth of population, clostridiosis or wet beds problems), necrotic enteritis and coccidiosis. The intestinal welfare is a not good known term that includes different status like absence of clinical...
Australian poultry producers are benefiting from a range of rapid, cost-effective diagnostic tests previously unavailable in Australia thanks to a Poultry CRC project being undertaken at The University of Melbourne. According to the project leader, Dr. Amir Noormohammadi, the industry has been very happy with the vastly improved turn-around time for test results as well as the increased level of understanding these tests now give us thanks to improved...
Researchers at the University of British Columbia have discovered an anti-virulence factor in Salmonella, knowledge that could be used to design improved Salmonella vaccines. Virulence factors allow a pathogen to thrive in the host and cause disease. An anti-virulence factor controls the degree of infectiveness. Salmonella are bacteria that infect a variety of vertebrae hosts. Salmonellosis, infection from Salmonella, can lead to gastroenteritis or typhoid fever -- a severe...
It is widely accepted in many parts of the world that chick anaemia virus (CAV) can have a serious economic impact on the poultry industry through direct clinical and potentially even more damaging, sub-clinical disease. CAV was first identified in 1979 and since then has been found in all parts of the world where poultry are kept commercially. The causal virus is a very small circovirus, resistant to acid pH, ether, chloroform and heat. Vertical...

Intestinal parasites (worms) are very common in chickens in the backyard type poultry flocks. The presence of a few parasites do not usually cause a problem. However, large numbers can have a devastating effect on growth, egg production, and over-all health. The concentration of parasite eggs in the chickens environment is one factor which plays a major role in determining the severity of the infection. The chickens pick up the parasite eggs directly by ingesting contaminated feed, water, or...
A world-first discovery made by a Monash University PhD student working at CSIRO’s Australian Animal Health Laboratory (AAHL) in Geelong, has poultry scientists worldwide taking a fresh look at the devastating bacterial disease, necrotic enteritis. In a paper published on 8 February in the respected 'open access' international journal PLoS Pathogens, Anthony Keyburn and a team of Australian scientists outline the discovery of a new toxin and the...
Infectious Laryngotracheitis (ILT) is usually considered to be a backyard flock problem. However, this disease continues to plague the poultry industry with sporadic episodes across the province of Ontario. Due to the persistent, latent, infectious nature of the virus, it can perpetuate itself, even after vaccination. Rolling reaction from chicken embryo origin (CEO) vaccines and transmission from backyard flocks keeps the industry at high alert for this disease. ILT is on the list of four...
Have you thought about what may be happening within the guts of your hens? If not, they may look like this:
However, if your hens have an infestation of capillaria (hair) worms, there may be little to see unless you have a microscope, but the gut lining could be even more damaged than by the roundworms (ascaridia) in the picture above. Some free range...
A new test for APV (APV-N) is available at the Uuniversity of Minnesota Veterinary Diagnostic Laboratory. Developed by scientists within the University, the new test boasts several advances: 1. Saves time: More tests can be performed in less time with the new test. The RT-PCR cycling time has been reduced by more than 50%. 2. Reduced basic sample cost: Large scale testing is more economical. The basic cost of the RT-PCR step has been reduced by 40%. 3. Increased...
The sub-therapeutic usage of antibiotics in livestock production is under severe scientific and public scrutiny because their use has been linked to the development of antibioticresistant pathogenic bacteria, which pose a threat to human health (Smith et al., 2003). As a result of such concerns, the European Union imposed a complete ban on antibiotic growth promoters (AGPs) in livestock production on January 1, 2006. Although a complete ban on AGPs has not been implemented in many countries,...

The effects of Escherichia coli, hen age, and dietary Bio-Mos and Flavomycin were studied to determine their influence on poult performance from 1 to 21 days. Day-of-hatch male turkey poults (British United Turkeys) were orally gavaged (1 ml) with 10 8 CFU/ml E. coli or sterile carrier broth. Within each E. coli treatment group, poults from two different hen ages (33 and 58 weeks of age) were fed diets containing Bio-Mos (2 lb/ton feed) and Flavomycin (2 g active ingredient/ton feed),...

Nutritionists, feed manufacturers, farmers and industry poultry managers are becoming increasingly aware of the fact that intestinal functions (i.e., digestion and absorption) and the intestinal barrier (as the first line of defense against aggressions arising from the luminal content) have major roles in animal performance and production. The following paper examines some of the processes that occur in the brush border region, among which are digestion and absorption capability, mucin...
Researchers say studies do not confirm whether wild birds are carriers of the H5N1 bird flu virus. VOA's Luis Ramirez reports from Bangkok, where experts were gathering to figure out better ways to track how the disease is spreading. Experts meeting in said they have been dealing with data that might be unreliable because there is no uniform system of checking H5N1 infection among wild birds. The Food and Agriculture Organization brought together more than 70 experts from 12 countries....
