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.
Dr. John Glisson, Professor at the University of Georgia, talked about the future control of avian diseases: From Pasteur to Genomics, at the Merial IBD summit, organised on January 26, 2010 in Atlanta, Georgia....

On 27 July 2015, Germany’s veterinary authorities notified the European Commission via an ADNS and OIE announcement that a highly pathogenic avian influenza H7N7 had broken out in a poultry flock of 14,104 layer hens in Herzlake Municipality, in the rural district of Emsland, Lower Saxony (see the flags on the map below). An egg-laying decline, reduced food intake and a higher mortality rate were observed on 24 July. For these reasons, samples were taken to be analysed for...

Gut health is a very important determinant for health and performance in production animals. The intestinal innate immune system is central in maintaining gut health. Each feed intake leads to postprandial (low-grade) inflammation response in the (small) intestines, the magnitude of which is related to the caloric value, the glycemic index and specific feed components. If not contained, postprandial inflammation could lead to undesired consequences such as muscle...

Managers of broiler parent stock face the challenge of intense feed restriction (Renema et al., 2007) because of over 4-fold increases in body weight (BW) over the last 50 years (Zuidhof et al., 2014b). Body weight control is of primary importance for broiler hatching egg operators. Therefore, feed allocation decisions have become a major focus. How much should you feed the birds? It depends on their age, their BW, rate of gain, and level of production. How much...

  Big liver and spleen disease or hepatitis splenomegaly syndrome (HSS) is clinically characterized by increased mortality and decreased egg production in both broiler breeder hens and egg-type chickens, usually ranging from 30 to 72 wk of age. On gross examination, blood-tinged fluid can frequently be observed in the coelomic cavity, and liver and spleen are typically both enlarged (19) . ...

INTRODUCTION Alphitobius diaperinus is one of the most predominant poultry litters inhabiting insect species all over the world. It has been shown to be able of transmitting a large variety of poultry pathogenic organisms, such as viral agents (IBDV…) [1], bacterial disease organisms (Salmonella spp, Campylobacter spp…) [2] and several poultry parasites. Understanding the biology, the epidemiology and the...

Introduction While broiler breeders are chickens, and they are susceptible to the same diseases that affect other chickens (broilers, layers, purebred, small flock, etc.), they tend to have specific diseases with only a few in common with those of other types of chickens. Exceptions, based on our diagnostic accessions, are coccidiosis and infectious laryngotracheitis, which are diseases that have occurred frequently in both commercial...

Even vulnerability of market conditions cannot stop the growth of Indian Poultry Industry today. Continuous improvement in genetic potential targeted towards getting better performance from the bird has made this unbelievable success realistic today. Along with the genetic upgradetation, the success can also be credited to nutritional awareness amongst the producers. It however fails to address the crucial issue of conferring adequate immunity to the bird against...

The problem has been detected in broilers of above 30 days of age. P.M reveals symptoms complicated with respiratory infections and bundled up with E.coli. The P.M lesions commonly seen are enlarged liver and pale swollen kidneys and sometimes fluid seen in the pericardial sac. The photo has been uploaded for reference in my profile. The vaccination includes ND killed with F strain in drinking water on the 7th day and IBD + on the 12-14th day. Could...

Research and development at Diamond V over more than 70 years has led to product technologies proven to support the immune system, particularly in its response to respiratory challenges (Jensen et al., 2008 and Moyad et al., 2009). Building on this work, Embria Health Sciences, a division of Diamond V, developed the human supplement EpiCor®. EpiCor demonstrated, through human clinical trials, a reduction in symptoms of...

The avian immune system consists of two components: Innate immunity and adaptive immunity. The innate portion of the immune system serves as the bird’s first line of defense against non-specific challenges. The adaptive side defends against more specific challenges that cross the intestinal wall or respiratory barrier and attack the bird systemically. Published reports demonstrate feeding Diamond V Original XPCTM (XPC) has...

Disease control in poultry production is based on several factors of which some are in the hands of the poultry producers, farmer and responsible veterinarian, like disease monitoring, diagnosis as well as disease prevention by implementing bio-security and optimal protection by vaccination. Eradication of certain pathogens, especially those being vertically transmitted, is...
