Forty-eight grower pigs were used to evaluate the effects of feeding low phytic acid (LPA) corn, LPA soybean meal, normal corn (NC), normal soybean meal (NSBM), and phytase on nutrient digestibility and excretion. Barrows were blocked by BW (initial BW = 45.3 ± 1.6 kg) and randomly assigned to 1 of...
