Trace minerals are often supplied in the forms of inorganic salts such as sulphates into poultry feed to meet the requirements. The ionic bonds in inorganic salts of minerals are very weak allowing the metal ion to disassociate once in contact with water, binding up diet antagonists such as other minerals, vitamins, and enzymes. To mitigate these negative effects technologies such as organic miner ...

Despite extensive research on reduced protein (RP) diets in broiler chickens, the consequences of such practices for gut health and barrier function are not well defined. This study was conducted to investigate the effect of reduced protein and the source of protein. The control normal protein level diets had either meat and bone meal (MBM) or an all-vegetable diet (VEG). Accordingly, four diets w ...

Broiler chickens grow rapidly with nutrient requirements changing daily. However, broilers are fed 3-5 diet stages throughout their growth, meaning nutrients are under- and over-supplied throughout production (Kleyn, 2013). Thus, blending rations on a daily basis to meet the daily energy and lysine requirements may improve the efficiency and reduce the coefficient of variation (CV) in broiler floc ...

Necrotic enteritis (NE) is an enteric disease of poultry caused mainly by a spore-forming grampositive bacterium, Clostridium perfringens, resulting in decreased growth, high mortality, and increased veterinary costs (Wade and Keyburn, 2015). While supplementing poultry diets with antibiotics can control NE, emerging antibiotic-resistant microbes and transfer of such resistance factors into human ...

Plants extracts (PE) have shown promising effects on performance and intestinal health in broilers. Their potential as antimicrobial (AM) alternatives has been studied for years (Adhikari et al., 2020). A feeding study was conducted to examine the effect of a micro-encapsulated product composed of eugenol and garlic tincture on growth performance, mortality, intestinal lesions, jejunal gene expres ...

BackgroundMaintaining and improving gut health is fundamentally important as the gut supports optimal digestion and therefore performance and profitability of production. Managing gut health through barrier function is regarded as a new frontier for disease prevention across different species [1]. In poultry, considerable research has been done on improving animal performance and gut health throug ...

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 ...
