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.
Introduction Poultry industry is one of the fastest growing segments of the animal industry. The worldwide consumption of poultry is increasing. Today's bird has the potential to grow rapidly because of intensive genetic selection so they are more susceptible to stressors of the respiratory and circulatory systems. The poultry industry faces the maximum economic losses by increase in...

With the ever increasing need for animal protein sources for human consumption, the poultry industry always coped up to meet the needs at an affordable manner. The conditions in developing countries for the production of either broiler or table egg may not be entirely free of unseen losses. The following article will review briefly about such losses by gut disorders and the approaches to avoid the same. Broiler production in major countries is estimated to total 74,237,000...

Infectious bursal disease (also known as IBD, Gumboro Disease, Infectious Bursitis and Infectious Avian Nephrosis) is a highly contagious disease of young chickens caused by infectious bursal disease virus (IBDV), characterized by immunosuppression and mortality generally at 3 to 6 weeks of age. The disease was first discovered in the USA, near the town of Gumboro, Delaware in 1962. It is economically important to the poultry industry worldwide due to increased susceptibility to other...

Introduction Aspergillosis is frequent, economically important, fungal disease of different avian and mammal species caused by fungi of the genus Aspergillus. The disease is characterized by inflammatory changes in the respiratory system and sometimes has generalized onset when more organ systems are affected. Clinical signs of aspergillosis depend upon which organ or system organ are involved and whether infection is...

Dear colleagues, This is a case of a 6000 layers flock, 36 weeks of age. 1.5 months ago the flock was suspected and tested for salmonellosis which came out to be positive. The flock was treated with gentamicin and bcomplex injection for 3 consecutive days. The mortality was reduced for a few days but then it increased again. The post mortem lesions show extremely fragile liver and blackish necrotic mucosa at the duodenal part. Copper sulphate and...

1. Introduction The occurrence of ‘wet litter’ in meat chicken sheds is associated with concerns regarding animal welfare, flock health, food safety, environmental impacts and reductions in production efficiency. Mitigating wet litter will only be achieved when there is thorough understanding of the multidimensional causal factors. This will require a multidisciplinary approach to understand the hydrology in...

Gumboro Disease or Infectious Bursal Disease (IBD) is one of the most common diseases of commercial poultry in Asia. In the clinical acute form (vvIBDV), the disease causes significant economic losses due to mortality, reduced performance and immunosupression that lead to increased susceptibility to other diseases. The IBD virus is extremely resistant to environmental conditions and chemicals. Therefore the control of the disease must take into consideration strict biosecurity combined with...

Introduction Antibiotics have been used for decades to improve poultry performance with low cost of implementation and ease adding to feed and water (Fernandez-Rubio et al., 2009). However, currently concern about possible antibiotic residues and resistance has arisen restrictions of antibiotics use in poultry (Jan et al., 2007; Saberfar et al., 2008). Because of this fact, industry and researchers have had to look for...

Each year, layer flocks in Denmark are infected with Salmonella. These infections, which are caused by several different serological types, are usually detected by means of compulsory Salmonella monitoring samples, and usually do not cause any clinical symptoms in the hens. Eggs from such Salmonella-infected flocks constitute a well-known risk to humans who eat raw or insufficiently heat-treated eggs (EFSA/EDC 2013). In 2013, however, the infection-source report...
