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.
ANTIVIRAL PROPERTIES
Very few know of the antiviral properties of Orego-Stim®. Orego-Stim® acts against enteric viruses the same way it acts against coccidiosis and ileitis. As the enteric virus needs a host cell (in this case, it is the enterocyte) to undergo the process of replication, therefore Orego-Stim® can control viral enteric diseases such as those caused by rotavirus and coronavirus.
Porcine Rotavirus

New federal regulations require most egg producers to take steps to prevent the spread of Salmonella enteritidis, reports the American Veterinary Medical Association. The FDA rules affect the purchase of chicks and young hens, sanitation in production facilities, testing for the bacteria, and storage of eggs at farms with at least 3,000 laying hens. An FDA announcement states the rules are expected to reduce the number of S enteritidis infections by 60%, preventing about 79,000 cases of...

Background of outbreak of Sudden Death Syndrome in Kathmandu Valley.
During the first week of August 2008 there sudden increase in mortality of broilers above 6 week age (Table 1). There are no premonitory signs. Just before death, birds appear normal and it is common to observe the birds feeding, drinking or walking normally. Then suddenly, affected birds exhibit clinical signs such as extending their neck, squawk and start wing beating...

The discovery of swine flu in birds in Chile raises concerns about the spread of the virus, the UN warns.
Last week the H1N1 virus was found in turkeys on farms in Chile. The UN now says poultry farms elsewhere in the world could also become infected.
Scientists are worried that the virus could theoretically mix with more dangerous strains. It has previously spread from humans to pigs.
However, swine flu remains no more severe than seasonal flu.
Safe to...

Animal welfare is a complex concept but there is general agreement within the scientific community and beyond that farm animals should be able to move easily and be in good health.
One welfare issue of particular interest in the poultry sector is lameness in broiler chickens. According to a group of French researchers, producers often underestimate the amount of lameness in their broiler flocks and in doing so they risk reducing the birds' welfare as well as product...

Reducing water hardness may increase its ability to remove bacteria from broiler chicken skin, according to Agricultural Research Service (ARS) scientists in Athens, Ga. Water hardness varies in different geographical locations, but most water tested in the United States has some degree of hardness.
"Hard" water has higher concentrations of dissolved minerals, such as calcium and magnesium. Water is softened by removing these minerals, either mechanically or...

As the European Union moves closer toward implementing its ban on the remaining feed grade antibiotics growth promoters in January 2006, the Asian poultry markets are on their toes and closely observing the situation in the EU, realizing that this change is inevitable. As a result, the scene in Asia has been set not to simply sit back and await this expected transformation, but rather, to participate by embracing this change in the best way possible, that is to...

Providing a clean, safe and sanitized water supply is crucial in assuring flocks perform their best. However, before implementing a daily water sanitation program, it is important to thoroughly clean as much of the water distribution system as possible. Line cleaning is necessary before providing birds with sanitized drinking water because even low levels of sanitizer placed in dirty water lines can result in the biofilm sloughing off, which clogs drinkers so that water is restricted to the...

Poultry infected with the parasite Eimeria maxima usually develop avian coccidiosis, a disease estimated to cost producers globally more than $1.2 billion every year. So Agricultural Research Service (ARS) immunologist Hyun Lillehoj has been working with colleagues in ARS and around the world to find dietary supplements that strengthen the poultry immune system.
Lillehoj, at the ARS Animal Parasitic Diseases Laboratory in Beltsville, Md., cooperated on the research with...

This study was conducted to evaluate the effects of prebiotic ( Fermacto ) in low protein diet on serum cholesterol and intestinal microbiota of broiler chicks. One hundred and fifty six 1-day old Ross 308 broiler chicks of both sexes were used for 42 days. The chicks were randomly allocated to 12 pens containing 13 chicks each with 3 replicates and assigned to receive one of the 4 dietary treatments of 2 levels of protein (low and high) and 2 levels of prebiotic (0 and 0.2%) in a...

Eye disorders are not generally prevalent in poultry on a flock basis. However, as birds rely heavily on their sense of sight to carry on their daily activities, an increased incidence of eye problems can result in decreased flock performance. A visually impaired bird is at a major disadvantage in competing for food, water, and social position in a population of birds. Ammonia Toxicity The most common eye irritant in intensive...

Are early-life conditions important?
Production systems for laying-hens are continuously exposed to infectious pathogens. To prevent infections from spreading through the flock, various control methods are used nowadays. However, these methods not only increase production costs, but also prevent laying-hens from building up their own reserves to combat these threats. The capacity to adapt in order to withstand threats is considered to be well-developed,...

Reoviruses are widespread in nature and have been isolated from a variety of animals. These viruses have also been isolated from humans and in fact the name reovirus is a mnemonic for respiratory (r) enteric (e) orphan (o) since the virus was isolated from the human respiratory and enteric tract, but was not associated with disease. In some species of mammals (primarily mice) these viruses have caused liver, pancreatic, lung, and heart disease and central nervous system...

Bacteria are microscopic living organisms. All bacteria are not detrimental to animal health. In fact, many bacteria are beneficial and necessary for such processes as food digestion, manufacturing of some dairy products, etc. Classification of bacteria into species is done so disease producing organisms may be separated from those that are harmless or beneficial.
Successful control of bacterial diseases entails isolating and identifying disease-producing species, if present, and...

History
Spiking mortality syndrome of chickens (SMSC) has been classified as such for approximately ten years. During the first experiences with the disease a number of causative agents were implicated, yet the symptoms remained relatively the same.
From approximately 1988 to 1990 the syndrome reached critical epidemic proportions particularly in the Delmarva area of the U.S. Isolated cases were also reported at that time...
