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.

Challenges in poultry nutrition Today, commercial poultry nutrition no longer encompasses just the ‘pure’ delivery of the nutrients needed by the animals for their preservation, growth and health. It must also be flexible in adapting to changing statutory regulations and keeping up with increasing consumer demands – beginning with eliminating feed of animal origin by using carefully selected raw materials, reducing the use of drugs such as antibiotics, ensuring...

Dysbacteriosis, an imbalance in gut microbiota, impairs nutrient absorption and growth in broilers. Severe cases can cause wet litter and high mortality. AGPs have long been used to enhance gut health and performance, but their prolonged use raises concerns over antimicrobial resistance in birds and humans. Removing AGPs from broiler diets has reduced performance and increased gastrointestinal tract (GIT) diseases. To mitigate the impact of AGP-free diets on broiler performance, various...

Gut health challenge is one of the major factors affecting production and profitability in commercial laying hens. In addition, chronic heat stress results in lowered feed intake, egg production, egg quality, gut microbiome and also impairs acid-base balance in laying birds. Numerous data support that laying birds fed with organic acid improved egg production and quality (Sakdee et al., 2018; Zhang et al., 2022). Butyric acid, an important organic acid serves as a primary source of energy...

1. Introduction Chickens represent the most widespread source of animal protein that is acceptable for nearly all communities, and, not surprisingly, the highly efficient commercial production of chickens is practised daily worldwide. However, chickens also represent a reservoir of zoonotic agents like Salmonella or Campylobacter. Chickens in commercial production are hatched from disinfected eggs in a clean hatchery environment, despite Gallus gallus being evolved to hatch in...

1. Introduction For decades, the livestock production sector has focused on improving animal production efficiency to stretch out the world population’s needs concerning farmed products [1]. This is particularly true for conventional broiler chickens’ production, where advancements in genetics, nutrition programs, management strategy, and medicine have resulted in more efficient birds, allowing a decrease of the slaughter age dramatically [2,3]. This is well illustrated...

1. Introduction Broiler chicken diets primarily consist of cereals, which are often contaminated with multiple mycotoxins [1]. According to the Food and Agriculture Organization (FAO), above 25% of the global food crops are contaminated with mycotoxins [2], causing a USD 5 billion annual economic loss for North America [3]. The fungi Fusarium verticillioides and Fusarium proliferatum are prominent pathogens of corn and produce fumonisins (FB1, FB2, and FB3), while Fusarium...

Introduction to Immunity Immunity refers to the body's ability to resist or defend against infections, diseases, and other unwanted biological invasions. There are two main types of immunity. Innate immunity is the host's first line of defense against invading pathogens but some pathogens particularly immunosuppressive viruses have evolved sophisticated mechanisms to evade the host's innate immune responses and survive within the host. Adaptive Immunity targets...
