This study determined the effects of feeding a corn- and soybean mealbased diet (control) or a low nutrient excretion (LNE) diet, formulated with reduced dietary CP and additional synthetic AA, low phytic acid corn, and phytase,
on pig growth performance during the grower (BW = 32 to 77 kg) and finisher (BW = 78 to 126 kg) periods and on carcass and bone characteristics at slaughter. It was concluded that feeding LNE diets resulted in the maintenance of overall growth performance, bone variables, and carcass characteristics. However, further refinements are still required in the nursery and grower phases of pig production to optimize LNE diet use by the swine industry.
