Objective: To describe added vitamin and trace-mineral concentrations used in the US swine industry for breeding growing pigs. Materials methods: A convenience sample survey of nutritionists from 18 production systems representing approximately 2.3 million sows or 40% sow herd was conducted to characterize diets. Data were compiled by dietary phases determine descriptive statistics. Nutrients evaluated vitamins A, D, E, K; biotin; choline; folic acid; niacin; pantothenic pyridoxine; riboflavin; thiamin; B12; betaine; C; carnitine; copper; iodine; iron; manganese; selenium; zinc; cobalt; chromium. Questions about supplementation D a cross-linked AD3 beadlet, potential use natural (d-alpha-tocopherol) E as source chelated trace minerals included. Results: Results indicated variation, but most included at above total requirement estimates reported National Research Council (2012). Chelated sources partial complete copper, manganese, zinc ranged none 46% 77% selenium across diet type.
