Effects of carbohydrase and phytase enzymes supplementation within low energy diets on performance and energy utilization of broiler chickens

Carbohydrases and Phytase in Poultry and Pig Nutrition: A Review beyond the Nutrients and Energy Matrix

“…Regarding the energy matrix, studies have reported that the supplementation of carbohydrases (e.g., xylanase, β-mannanase, β-glucanase, and α-amylase) and phytase provides formulators with the opportunity to reduce the ME content of the diet by around 100 kcal/kg in diets to broiler chickens [159][160][161][162][163], and pigs [13,40,74,164]. Recently, de França et al [165] reported that the supplementation of enzymes (xylanase, β-mannanase, β-glucanase, and phytase) in broiler diets makes it possible to reduce the energy density by a 200 kcal/kg diet without affecting growth performance and jejunal morphometry.…”
