Exogenous phytase and intestinal uptakes of amino acids

PETER SELLE, SHEMIL MACELLINE, PETER CHRYSTAL and SONIA YUN LIU discuss how phytase generates pronounced improvements in apparent amino acid digestibilities.

Maximal value addition from combined use of phytase and carbohydrases in corn-soy broiler diets

LEON HALL and Dr NITIN GHADAGE present a broiler trail demonstrating that a ‘3-in-1’ enzyme, containing 3-phytase, ß-xylanase and ß-glucanase, significantly improved bird performance (bodyweight gain and FCR), and digestion of phosphorous.

Xylanase – improving feed efficiency and gut health

VICKY YOO consider xylanase enzyme as one of the solutions to improve the digestibility of main feed ingredients, as a strategy to cope with rising feed costs and support sustainable animal production.

Selecting the right xylanase to optimize the production of oligosaccharides with potential prebiotic effect

GUILHERME PASQUALI describes how a combination of a GH10 xylanase and β-glucanase depolymerizes arabinoxylans into xylo-and arabinoxylo-oligosaccharides which can act as prebiotics and can be used by some bacteria resulting in the production of short chain fatty acids (SCFAs). The higher production of SCFAs can support better gut function.

The potential of dietary glutamine and glutamate in reduced crude protein broiler diets

SHEMIL MACELLINE, PETER CHRYSTAL, MEDHI TOGYANI, PETER SELLE and SONIA LIU review the potential of dietary glutamine (Gln) and glutamate (Glu) fortification in reduced-crude protein (CP) broiler diets and suggest it may be more rewarding to fortify reduced-CP broiler diets with dietary Gln than Glu as Glu may be more extensively catabolised in enterocytes.

Importance of fiber in modulating feed intake in broiler breeders – Part 1: Dietary fiber characterization

DAVID CADOGAN and MINGAN CHOCT describe dietary fiber within the feed context, from chemical, physical and functional points of view and speculate on how certain NSP entities can be used to manage intake in broiler breeders without affecting egg production and hatchability.
