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.
I. INTRODUCTION Exogenous phytase improved ileal amino acid digestibility by an average of 5% based on 745 observations across 24 studies in a systematic review (Cowieson et al., 2017). Nevertheless, the post-enteral availability of amino acids is ultimately determined by their transition across enterocytes in the gut mucosa. Amino acids may be denied access to the portal circulation because they may enter numerous anabolic pathways, or they may be catabolized for energy...

I. INTRODUCTION Over the last few decades, laying hen performance potential has largely been improved by genetic selection: egg production increased from 11.8 to 21.0 kg eggs per hen housed, FCR reduced from 3.29 to 1.96, mortality from 19.1 to 5.6% and body weight from 2.42 to 2.20 kg between 1970 and 2000 (Jeroch, 2011). Production cycles of 100 weeks without moulting will become commercially feasible based on improved laying persistence, although egg shell quality is still a...

I. INTRODUCTION
The recent major drop in the cost of DNA sequencing, combined with advances in the annotation of 16S rRNA gene microbial databases and analysis tools, have all contributed to the “golden age of microbial ecology” (Oakley et al., 2014). Poultry researchers have leveraged and applied these advances to define approaches that may be taken to manipulate microbiota to improve a number of poultry production steps. One of the major issues in...

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...

I. INTRODUCTION Improved FCR was observed in broiler chickens fed a slow digestible starch diet compared with a fast digestible starch diet (Weurding et al., 2001). Furthermore, Enting et al. (2005) indicated that a slow digestible starch diet fed to broiler chickens can spare amino acids (AA). Finally, Liu et al. (2017) and Truong et al. (2017) concluded that starch digestion kinetics play a role in broiler performance, but that protein digestion kinetics may be more important...

Optimal in-feed amino acid ratio for laying hens based on deletion method
Suggested link
A previous study highlighted differences between a low protein (LP) diet and a higher concentration of amino acids (AA) for intestinal permeability and performance (Barekatain et al. 2018). It is hypothesised that individual AA such as glycine (Gly), glutamine (Gln) and arginine (Arg) may improve gut health and barrier function of birds fed LP diets. To test this hypothesis in a broiler study, two basal diets were prepared as follows: 1) a standard diet (SD) containing 225 g/kg crude protein...
