Effect of dietary nucleotide supplementation without or with in-feed antibiotics on piglet performance and energy and nutrient digestibility was determined. Supplementing antibiotics without or with nucleotides (1000 ppm) increased weight gain (P < 0.05), whereas increasing nucleotide levels in antibiotic-supplemented diets linearly decreased (P < 0.05) energy and nutrient digestibility.
