The effect of Christmas Island rock phosphate on

Christmas Island Rock Phosphate (CIRP) is known to cause renal fibrosis and depressed growth performance when it is used as a source of calcium and phosphorus in grain based rations for grower pigs. As a result its full potential as an inexpensive mineral supplement has not been realised. This thesis presents a 4 part study of the toxic effects of CIRP and investigates the economic feasibility
