Hosted by the University of Arkansas, the University of Illinois and AB Vista, the International Phytate Summit was the third in a series of phytate and phytase summits. The summit brought together experts in animal nutrition to further our knowledge and understanding of the anti-nutritional factors of phytate and identify advances in diet formulation to combat the anti-nutritional effect of phytate. The International Phytate Summit provides a dedicated platform for in-depth discussion on phytate. Understanding phytate and its impact on diets is the first step to optimising the value chain of phytate destruction.
Developed to harness the information and ideas presented at the 3rd International Phytate Summit, this book aims to provide you with a scientific, peer-reviewed source of the current information and future directions regarding phytate, phytate esters, myo-inositol, calcium and phosphorous, trace minerals and amino acids in pig, poultry and aqua nutrition.
