The role of added feed enzymes in promoting gut health in swine and poultry.

摘要: The value of added feed enzymes (FE) in promoting growth and efficiency nutrient utilisation is well recognised single-stomached animal production. However, the effects FE on microbiome gastrointestinal tract (GIT) are largely unrecognised. A critical role host nutrition, health, performance quality products produced played by intestinal microbiota. can make an impact GIT microbial ecology reducing undigested substrates anti-nutritive factors producing oligosaccharides situ from dietary NSP with potential prebiotic effects. Investigations molecular microbiology techniques have demonstrated FE-mediated responses energy broiler chickens that were associated certain clusters bacteria. Furthermore, investigations using specific enteric pathogen challenge models efficacy modulating gut health. Because probably change substrate characteristics along GIT, subsequent microbiota will vary according to populations present at time administration their reaction such changes. Therefore, administration, rather than being absolute, a continuum or population responses. recognition thus health stimulate development capable benefit under production conditions. review brings light opportunities challenges for major (carbohydrases phytase) poultry swine species focus
