Interactions of Carbohydrases with Unconventionally High Doses of Phytase on Nutrient Digestibility, Energy Utilisation and Bone Mineralisation in Broiler Chickens

Abstract

This thesis presents a literature review and reports on four experiments conducted to investigate the effect of multi-carbohydrase with or without phytase on the growth performance in broiler chickens. To scrutinise the mechanisms underlying these effects, a series of responses in relation to the digestibility of nutrients, energy utilisation, especially net energy of the diet, bone mineralization and gut microflora were examined.
