Poultry diseases
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.
The US Centers for Disease Control and Prevention estimates, each year, about 9.4 million people get sick from contaminated food. A new test may detect Salmonella infection in an early stage, allowing prompt action.
The USDA reports the leading cause of bacterial-related food illness in the U.S. is salmonella. About one million Americans get sick from salmonella annually, more than 19,000 are hospitalized and more than 370...

When a bird is vaccinated, or exposed to a viral or bacterial infection, a complex biological mechanism is set in motion which normally results in the elevation of the bird's specific defenses against the disease in question. Sometimes this process also raises non-specifically its defenses against other infections. The immune response is generated by a complex system of specialized cells, the lymphocytes. All vertebrates have such a system but those of birds and...

Gastrointestinal diseases pose a serious threat to industrial poultry breeding. Infections are caused by proliferation of naturally occurring intestinal microorganisms and their subsequent translocation to other organs and tissues of the birds. The consequences are a deterioration of feed conversion ratio, an increase in mortality and finally a reduction in productivity. According to the World Health Organization (WHO) this leads to a...

ANTIOXIDANT PROPERTIES A major preventive measure of lipid oxidation is the use of synthetic or natural antioxidants that function either by scavenging chain-carrying peroxyl radicals or by diminishing the formation of initiating lipid radicals. Synthetic antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) have long been used to control oxidation of lipids and vitamins in the feed, but recent concern over their use has created a need...

Osteoporosis (Caged Layer Fatigue) is a condition which manifests itself in several clinical signs. There is leg weakness and sometime paralysis. Affected birds are unable to stand and usually to move to the back area of the cage. They often fall onto their sides with leg outstretched. Birds which live for several days after going down may dehydrated or emaciate and are out of production. Although affected birds initially are alert and can continue to eat,...

We have broilers at 3050 mts in the Caucasus and we’ve done a detailed study about chicken breeding in altitude, which presented us alternatives (we’ve reached mortality percentages of 5.3) We want to get acquainted with experiences in the use of selenium doses (not from fish but from alfalfa) to replace phosphorus in cysteine, metionine and lysine, to give a true value to the protein. We also need information related to the provision of vitamin K in these broilers to...

Abstract Poultry litter becomes wet when the rate of water addition (urine/faeces/spillage) exceeds the rate of removal (evaporation). Anti-nutritional factors, toxins, pathogens and nutrient imbalances may cause wet litter directly by altering normal digestive physiology or indirectly by disturbing normal gut ecology. Poor quality ingredients and those with excess oligosaccharides or minerals can cause a...

Red mites are one of the most important pests of laying hen farms worldwide. More than 50% of layer batches encounter difficulties in managing red mite problems. Poultry red mite (PRM), scientific name Dermanyssus gallinae, is a nocturnal blood feeding ectoparasite of birds. PRM is an acarus that requires blood of its host for development and reproduction. It particularly infests laying farms due to long production...

Summary Antibiotic growth promoters (AGP) have been used sub-therapeutically in poultry and other livestock species for maintaining health and improving performance for more than 60 years. After the ban imposed in European Union on use of AGP in animal feeds and growing demand for antibiotic free animal products in other parts of the world, there is need to find alternative substances that can ensure animal health and...

I think the most debated issue nowadays in poultry is the use of antimicrobial drugs as feed additive. We all understand what the demerits are of using these antimicrobial feed additives but still we are not in a position to give up their usage voluntarily.
I believe that...
