An experiment was conducted, from 22 to 42-d-post-hatch, to evaluate the effect of different combinations of carbohydrases (CHS), citric acid (CA) and high-dose phytase in wheat-canola meal-based diets with very low content of non-phytate phosphorus (NPP) on growth performance, plasma calcium (Ca) and P and tibia ash (TA) content of broiler chickens. One hundred and ninety two 21-d-old male chi...
