Abstract

Level of feed intake did not affect the apparent total tract digestibility (ATTD) of calcium (Ca) and phosphorus (P) in gestating sows. Gestating sows had reduced ATTD of Ca and P compared with growing gilts. Formulating diets for sows using values obtained from growing pigs, therefore, may result in inaccuracies.
