chickens and turkeys which primarily affects the skin and tissues below the
skin in the abdomen of the bird. Gangrenous dermatitis is bilieved to be caused
by species of clostridia, usually Clostridium

trial in Bulgaria testing the effects of a mixture of probiotics, yeast and
organic on the growth and gut health of broilers. The experimental mixture
resulted in a shift in the microbial balance in the gastrointestinal tract in

condition affecting broilers and turkeys and is also known as pododermatitis
and paw burn, all of which refer to a type of contact dermatitis on the footpad
and toes.
Before the mid 1980, chicken paws
were of little value and were rendered with feathers, blood and other unslable

Nutritional modulation to enhance immunity in chickens
Prevention is better
than cure, as they say. Many nutrients, energy, amino acids, vitamins and
minerals - play different but significant roles in the immune response and so
can contribute to keeping birds in good health, without the need for
medication.
Presently, the aim of
commercial poultry breeding is to achieve higher body weight and maximum egg
production per unit of feed intake. However, there is a negative correlation
between...

Avian Influenza: Human Pandemic Concerns
Introduction
The likelihood that the next human influenza pandemic virus will emerge from the Asian strain of the H5N1 high pathogenic bird influenza virus that is causing widespread outbreaks in Eurasia remains unknown. (See Glossary for italicized terms.) Because these bird influenza outbreaks remain primarily an animal disease, there is hope that a human pandemic can be prevented. Eradication of the H5N1 high pathogenic...

Are American Commercially Produced Eggs Safe from Avian Influenza?
Why American commercially produced eggs are safe to eat:
When chickens become sick with Avian Influenza, one of the first signs of illness is that they stop laying eggs. In High Pathogenic Avian Influenza (HPAI), the more severe form of the virus, the illness is very sudden, egg production stops, and many of the birds will die from the disease.
In the United States, if HPAI should be identified within...
