Tibial mineralization in broilers as influenced by two levels of dietary calcium and phytase during subclinical necrotic enteritis

Abstract

<p>Bone development is an important welfare and production concern in the broiler industry. It is affected by a number of factors including genetics and nutrition (González-Cerón, Rekaya, & Aggrey, 2015). Improved genetics resulting in higher growth and body weight places additional demands on nutrition to maintain skeletal structure. Calcium is one of the most limiting minerals in skeletal development. The presence of phytic acid in many ingredients is a major issue as calcium is easily chelated and forms phytate mineral complexes that reduce its availability. Furthermore, high levels of calcium reduce the ability of exogenous phytase to hydrolyse phytate.</p>
