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 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...

A three-day symposium titled Gut Health in Production of Food Animals will be held November 14–16, 2016, in St. Louis, Missouri. The aim of this meeting is to discuss the role of good health in animal production and the dynamic and essential role the gut plays in it.
The symposium will include all species in animal agriculture and cover different aspects of the gut and important factors in gut health maintenance and disease. It will also provide a...

1. Introduction Probiotics display numerous health benefits beyond providing basic nutritional advantages. Probiotic products consisting of beneficial microflora can help to establish and maintain the balance of the intestinal microflora in commercial broilers. However, selecting a probiotic microorganism that has beneficial effects in broiler chickens requires an extensive search for the optimum...

Intestinal diseases are an important concern for modern poultry industry because of low productivity, increased mortality, reduced welfare and the associated contamination of poultry products with pathogenic bacteria and their toxins. Several pathogens (Viruses, bacteria and parasites) are incriminated as possible causes of enteric disorders either alone (mono-casual), in synergy with different other micro organisms (multi-casual) or with non-infectious...

Introduction. The gastrointestinal tract (GIT) is developmentally very active in the early period posthatch in poultry species (Uni et al., 2000). The intestinal crypts that form on the day of hatch become defined in the first 48 to 96 h and continue to grow rapidly during the first 7 d (Uni et al., 2000). The intestinal villi increase significantly in diameter and length during...

INTRODUCTION The chicken GI tract has a diverse microflora, containing more than 900 species of bacteria (1). In addition to biochemical functions, the microflora is responsible for digestion and subsequent nutrient absorption (2). One of the major influencers on the chicks’ microbial colonization is the environment, since GI colonization starts immediately after hatch (2). Under commercial conditions, maternal...

INTRODUCTION
A 2012 survey of the US broiler industry to determine and rank production challenges indicated that gut health management was paramount in the minds of those involved with live production (23). This is not surprising since intestinal integrity determines feed efficiency, the most important economic driver of the meat industry. Since then, some significant changes in the industry have sharpened the...

Bacterial chondronecrosis with osteomyelitis (BCO) is a leading cause of lameness in commercial broilers produced in North America (1, 2, 9) . The lesions most often occur in the proximal femora and tibiae and are associated with osteochondrotic microfractures and clefts in rapidly growing broilers....

Abstract
Dietary formic acid and its salts act against pathogens, helping to decrease pressure on the immune system and improving nutrient digestibility. The use of the double sodium salt of formic acid, with the same antimicrobial properties as formic acid, but with improved handling properties, has become more prevalent in poultry diets. In a trial conducted at a research farm in Taiwan, sodium diformate...
