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.
Calcium is an important cation in chicken diets, being the most abundant element in the body of the chicken. Its functions include: mineralization of bones, blood clotting, enzyme activation, neuromuscular function, muscle contraction, and intracellular signaling. However, high dietary Ca is a limiting factor for phytase efficacy and the formation of insoluble Ca-phytate complexes decreases Ca and P availability. Furthermore, Williams (2005) has shown high dietary Ca concentration in the...

Phasing out of in-feed antibiotics in the poultry industry has caused necrotic enteritis (NE) to become a primary concern in commercial poultry production in many countries. Damage to the intestinal mucosa caused by this disease leads to impaired broiler productivity. To gain a better understanding of the impact of NE on transcriptome changes, a whole transcriptome sequencing (RNA-seq) was performed on jejunal RNA of challenged broilers to identify the pathways affected by this...

I. INTRODUCTION Antibiotics as growth promoters (AGPs) have been extensively used at sub-therapeutic levels in poultry production to prevent diseases and promote growth performance. However, the persistent use of antibiotics can increase antibiotic-resistant bacteria and antibiotic residue accumulation in the animal products as well as potentially transferring resistant strains to humans through the food chain (Jazi et al., 2018a). Consequently, the poultry industry has been...

I. INTRODUCTION
One of the most sustainable types of production of animal protein is chicken meat production. Chicken production needs less feed consumption per kilogram of produced meat and uses less land and water for both farming and feed production. The major reason for this is the continuous improvement of animal performance, reflected in an ever decreasing feed conversion (kg feed consumed per kg body weight) and reduced time to achieve market...

Intensive farming is drastically increasing yearly in South East Asia to comply with the growing demand of animal protein of the region. Intensive farming has been possible worldwide thanks to the genetic improvements and technologic and productive investments done, which have allowed to reduce the breeding period while increasing the benefits. Animals are under a high pressure in this production system to achieve the desired productive parameters, which makes them more sensible to the...

Modern animal feeding includes prophylactic approaches for supporting intestinal homeostasis and immunity, in order to avoid dysbiosis, diseases, and need for antimicrobial medication. According to the principles of the One Health concept, the well-being of humans, animals and the environment are all connected, and at these times of a pandemic, avoiding the excess usage of antibiotics in animal farming is more important than ever.

I. INTRODUCTION There is considerable interest in the development of low protein diets balanced with supplemental amino acids for broiler chickens due to economic, environmental and bird welfare advantages (Moss et al., 2018). However, under commercial feeding conditions, chickens are exposed to various challenges of infectious and non-infectious origin. For challenges of infectious origin, even without any clinical signs of disease, animals affected by chronic subclinical...

I. INTRODUCTION The use of feed additives such as those based on essential oils or organic acids is increasing in poultry production as a result of a number of factors including legislation on restricting antibiotic use and consumer preferences for more natural, welfare friendly poultry production. Formic and propionic acid products have a strong antimicrobial activity and have been shown to improve bird performance and positively influence the gut microbiota (Emami et...

INTRODUCTION Supplementing poultry feed with specific enzymes improves the nutritional value of feed ingredients by increasing the efficiency of digestion and nutrient uptake. These enzymes help to increase the availability of nutrients particularly starch, protein, amino acids and minerals such as phosphorus and calcium from feed ingredients.

INTRODUCTION Pioneer colonization of intestinal microbiota has a major effect on driving the maturation and composition course of microbial communities over time (Juricova et al., 2013; Rodrigues et al., 2019; Wilson et al., 2019). Later, the cross-talk between microbiota composition and immune cells has been highly associated with the establishment of immune competence (Crhanova et al., 2011; Chung et al., 2012; Schokker et al., 2017; Duan, 2018). Germ-free mouse models have...
