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 Avian influenza viruses (AIV) infect animals and humans [1] and thus are of major relevance under the one health context. They are enveloped viruses belonging to Alphainfluenzavirus from Orthomyxoviridae family [2]. These negative sense and single-stranded RNA viruses present a genome that is fragmented into eight segments which encode for eleven proteins. These proteins possess individual function or form complexes during viral replication. The mechanisms underlying...

Introduction The main issues that burden the broiler industry today might be caused by genetic selection strategies, such as a rapid growth rate, a decreasing slaughter age and facilitating feed efficiency [1]. Indeed, achieving extreme growth potential is a serious biotic stress factor that is accompanied by health problems leading to systemic diseases [2,3]. The path mechanisms of most common infectious diseases, including pneumonia, sepsis and enteritis, are directly linked...

I. INTRODUCTION Salmonellosis remains one of the most frequent food-borne zoonoses, constituting a worldwide major public health concern. Although Salmonella can be acquired from a range of foods, poultry meat and eggs remain prominent (Antunes et al., 2016). Human salmonellosis cases in the US are estimated at 1.35 million per year (Centers for Disease Control, 2019a). Likewise, cases in the UK and EU have not changed significantly over the past decade. Success in controlling...

Introduction Influenza A viruses (FLUAV) from waterfowl are of global concern. Multiple pandemics have occurred as the product of genetic exchange between FLUAV circulating in humans and the avian reservoir (1). FLUAV contains eight gene segments, two of which encode for the surface glycoproteins hemagglutinin and neuraminidase (HA and NA, respectively). The other six for the internal gene cassette, comprised by the set of polymerases, PB2, PB1 and PA, the nucleoprotein NP, the...

A new stage begins in terms of vaccinations against Salmonella. From May 2021, Primun Salmonella E can be applied in laying the first live vaccine against Salmonella Enteritidis that has been authorized for that period. In this way, we give the respite that the producer had been asking for for a long time. The productive cycles of laying hens are getting longer and the immunity that has been given through the vaccines applied only in the rearing period, did not cover the new...
