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.

Non-starch polysaccharides are polymeric carbohydrates that are different from starch. NSP cannot be digested by the animals because they are cross-linked (a cross-link is a bond that links one polymer chain to another)....

Excess water in feces is a sign of alarm, an early indication of poor health, or a pointer to a suboptimal feed conversion. Wet feces lead to welfare problems such as footpad dermatitis and skin burns, while increasing the risk of carcass contamination and foodborne infections....

Introduction In poultry, the gastrointestinal tract accounts for twenty percent of the energy expenditure of the whole body (Choct, 2009). This energy requirement is variable and dependent on numerous factors influencing the highly dynamic nature of the intestinal environment. The intestinal environment including the mucosal structure and function is influenced by many factors including environmental management, embryonic incubation, dietary ingredients, protein level,...

Inflammation is a complex biological reaction to a harmful event, such as the presence of pathogens, toxins, or damaged cells. It involves the innate immune system, the blood vessels, and molecular mediators, promoting radical changes in the architecture and function of the tissue. Although inflammation is a...

Immunometabolism is the study of immunity and metabolism as an integrated system. The prototypical organ for such study is the gut. Central to the proper and optimum functioning of the gut, thus its immunometabolism, is the microbiota. Often the microbiota is considered only in the context of what functions, molecules and signals it provides to the host. However, the interactions between the host and microbiota must fundamentally be understood as bidirectional communication. In the realm of...

The importance of vitamin nutrition in poultry feeding has been recognized for decades, yet precise vitamin requirements for modern, high producing have not been investigated. Because of their low inclusion rates, vitamins have a relatively small impact on the cost of feed. Many vitamins lose activity over time or under high-temperature feed processing. Vitamins, especially the water-soluble vitamins, are tolerated at many times the established minimum recommended levels. Finally, the...

INTRODUCTION Cereal grains such as wheat, sorghum, barley, and corn are commonly used in poultry diets as major sources of energy. Knowledge of the ME content of cereal grains is critical for their efficient and sustainable use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME is the globally accepted system for describing the available energy for poultry (Hill and Anderson, 1958; Sibbald, 1982). The simplicity,...

Within an animal’s interactive physiological networks, the complexity of nutritional interactions is not solely confronted by the host but is made substantially greater since the animal plays host to entire communities of commensal and symbiotic microbes that derive nutrients from the host diet and provide vital nutrients to the host. The gut microbiome is involved in the development, function, and maturation of the host immune cells locally and systemically. Under the influence of...
