INTRODUCTION Coccidiosis is a major enteric disease of chickens that is caused by several distinct species of Eimeria protozoan parasites infecting different areas of the gut. Coccidiosis primarily damages epithelial integrity in the intestine decreasing nutrient utilization and resulting in an annual loss of over $3.2 billion in the poultry industry globally (1–3). With the onset of coccid ...

Necrotic enteritis (NE) is one of the top enteric infectious diseases in commercial broiler chickens that is caused primarily by Clostridium perfringens (CP) A/G strains and responsible for around $6 billion economical loss worldwide.  Coccidiosis is the major predisposing factor for NE. With gradual reduction and eventual withdrawal of antibiotic growth promoters from animal feed due to publ ...

Avian coccidiosis is one of the most economically damaging infectious diseases affecting poultry. The etiologic agent is Eimeria spp., an obligate eukaryotic intracellular parasite belonging to the phylum Apicomplexa, which infects chickens’ intestinal tracts and is transmitted through a fecal-to-oral route (7,49). Clinical manifestations of infection include damage to the intestinal epithel ...

The average commercial broiler consumes 3.2 kg of feed over 35 days to achieve 1.8 kg of body weight, compared with more than 20 kg of feed over 112 days to attain the same weight in the 1920’s. This improvement in poultry growth performance has been achieved, in large part, through advances in animal genetics, health, and nutrition, including the use of in-feed antibiotic growth promoters s ...

1. Introduction The CXC chemokine family consists of two subfamilies, delineated by the presence or absence of the tripeptide Glu-Leu-Arg (ELR) motif located in the NH2-terminal region and designated as ELRþ or ELR CXC chemokines, respectively (Fernandez and Lolis, 2002). CXCL8, also known as interleukin-8 (IL-8), belongs to the ELRþ CXC chemokine subfamily and functions as a neutrop ...

Dietary antibiotics have been used in the food animal industry for more than 60 years, not only to control infectious diseases, but also to increase feed efficiency and improve growth performance. In chickens, subtherapeutic, in-feed antibiotics can increase body weight gain up to 8% and decrease the feed conversion ratio (feed intake/body weight gain) up to 5%, both compared with an antibiotic-fr ...
