Poultry gut health
The efficient conversion of feed into its basic components for optimal nutrient absorption is vital for both broiler and broiler breeder production and welfare. Gut health, an intricate and complex area combining nutrition, microbiology, immunology and physiology, has a key role to play. When gut health is compromised, digestion and nutrient absorption are affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to disease. In addition, recent changes in legislation on the use of antimicrobials, differing feed requirements and more efficient birds highlight the need for a better understanding of gut function and gut health.

Introduction It is well known that antibiotic growth promoters (AGP) can improve production performance in birds (1) although the exact mode of action is still not completely understood. According to (2), a major hypothesis about the action of AGP is through the reduction of innate inflammatory response in the gastrointestinal tract (GIT) of birds. Now that the use of AGP...

Immunometabolism
The interface of the immune system and metabolism is an emerging field of study. Relatively recently, immunity and metabolism were treated as distinct processes carried out by an organism. Immunity was focused on the recognition and resistance to a pathogen and involved its own set of cells and tissue activities. Metabolism was solely the chemical...

INTRODUCTION Necrotic enteritis (NE) is an economically important disease of the poultry industry worldwide, and is mediated by Clostridium perfringens strains that produce necrotic enteritis toxin B-like (NetB), a β-pore-forming toxin (Yan et al., 2013). NE was described in chicken for the first time by Parish in England in 1961 (Parish, 1961). The disease has been estimated to cost the world poultry industry...

Introduction Necrotic enteritis (NE) is an acute clostridial disease of economic importance to the poultry industry [1]. NE is caused by Clostridium perfringens, a Gram-positive, rod-shaped, spore-forming, and oxygen-tolerant anaerobe [2]. C. perfringens is a normal component of the chicken gut microbiota and the alterations in the hostpathogen relationship that regulate the development of NE remain to be determined [3]....

Introduction Poultry are naturally adapted to hosting a complex gastrointestinal (GI) microbial community with hundreds of bacterial species and up to 1011 CFU per gram of gut contents (1). Benefits conferred by this microbial community (the GI microbiome) include promoting beneficial development of the intestinal mucus layer, epithelial monolayer, and lamina propria (2, 3),...

The aim of the study was to determine the effect of dietary supplementation of organic acids on the performance, intestinal histomorphology, and blood biochemistry of broiler chicken. The birds in the control (T1) group were fed the basal diet whereas in other treatment groups basal diet was supplemented with 2% butyric acid (T2), 3% butyric acid (T4), 2% fumaric acid (T4), 3% fumaric acid (T5), 2% lactic acid (T6), and 3% lactic acid (T7). Broiler chicken...
