Three metabolism trials were conducted to determine the effects of dietary calcium and phosphorus level upon calcium, phosphorus and nitrogen balance in growing swine. The nine pigs in each trial averaged 22.6, 25.2 and 26.5 kg initially for trials 1, 2 and 3, respectively. The diets contained three levels of calcium and three levels of phosphorus and were rotated among the pigs in the three trials. Feed intake was adjusted to metabolic size.
