Understanding limestone quality and calcium digestibility in poultry feed

Limestone included in poultry feed is the single largest contributor of dietary Calcium required by our birds for good bone and eggshell formation. In spite of its importance as a calcium source, little is known about the digestibility of the calcium from limestone, and how to best characterise differences in limestone quality. As many in the feed Industry will know, Chemuniqué have been investing heavily in a project run in collaboration with the University of Maryland, USA and the University of Pretoria; the objective being to better understand differences in the quality and digestibility of limestone sources used in poultry feed in South Africa. read more
