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 As we learn more about the negative impacts of calcium (Ca) on the availability of phosphorus (P), it highlights how little we know about Ca requirements, digestibility of Ca in ingredients, and their impact on P digestibility (Angel, 2019). These impacts can be direct or indirect through chelation with phytate, which can have a profound impact on the efficacy of phytase. Historically the ratio of Ca to P has been defined as total Ca to total P or total Ca to a form...

INTRODUCTION The physical form of the diet is a tool to improve broiler live performance, especially feed efficiency. However coarse feed particles enhance gizzard function, which was referred to as the pacemarker of gut motility (Xu et al. 2015a, Xu et al. 2015b, Kheravi et al. 2017). Studies respect to particle size impact on health, digestive efficiency and broiler performance were developed more than 60 years ago (Pacheco et al. 2014, Xu et al. 2015a, Xu et al. 2015b)....

INTRODUCTION Pelleting is the most common form of thermal processing used in broiler feed manufacturing, aggregating the particles of ingredients into a cylinder by means of mechanical pressure, moisture, and temperature. A wide range of temperature and moisture can be used during conditioning, usually from 60°C to 100°C and 12 to 18% moisture (Hancock, 1992). Increase in feed intake (FI) is among the main reasons that motivate agroindustries to pellet feeds...

Introduction Animals used for food production have been genetically selected for feed intake and muscle development (or milk and egg production) and are therefore divergent from their ancestors. In addition, these animals are reared in conditions that favor fast spread of pathogens. The high uptake of feed and the fast growth make these animals prone to intestinal disorders, what has been neglected in the past because of the use of low doses of...

Necrotic enteritis (NE) is an important enteric disease in poultry, caused by the overgrowth of certain Clostridium perfringens strains, which evokes intestinal tissue damage. In its acute clinical form, the disease is characterized by a sudden increase in flock mortality, and gross lesions that are usually, but not always, restricted to the small intestine. In the sub-clinical form, no peak mortality is observed, but intestinal damage will lead to decreased nutrient digestion and...

INTRODUCTION Under current production systems, turkeys have traditionally been protected from pathogenic microorganisms by vaccination and antibiotics. For decades, subtherapeutic doses of antibiotics have commonly been used within the poultry industry to improve production performance and reduce pathogenic microbial challenges. However, negative consumer perception and increased regulatory guidance prohibiting the use of growth promoters or antibiotics within the animal...

INTRODUCTION Feed management practices, aiming to improve animal welfare without increasing production cost, are becoming more important for the poultry industry (Mateos et al., 2012). In broilers, ad libitum feeding of pellet feeds is associated with a reduction in starch digestibility (Svihus and Hetland, 2001; Abdollahi et al., 2011; Serrano et al., 2013) and an increase in the incidence of metabolic problems (e.g., ascites and lameness) and mortality (Leeson et al., 1999;...

1. Introduction Redox biology is a very quickly developing area of modern biological sciences, and roles of redox homeostasis in health and disease have recently received tremendous attention [1–6]. There are a range of redox pairs in cells/tissues responsible for redox homeostasis maintenance/regulation. They include, but are not limited to, NAD+/NADH, NADP+/NADPH, GSSH/GSH (glutathione system), Trxox/Trxred (thioredoxin system), protein thiolsox/protein thiolsred. It is...
