Trace mineral levels evaluated for swine

摘要

ASWINE diet is composed of many nutrients — including energy, amino acids, macrominerals, vitamins and trace minerals — and the formulation of swine diets involves combining the best-cost feed ingredients into a complete feed to meet the pig's nutritional needs for its age, size, production status and genetic potential.The macro-minerals calcium and phosphorus are generally sourced from limestone and dicalcium or monocalcium phosphate — all of which contain appreciable amounts of micro-minerals, ironand manganese — which can supply levels for grower/finisher pigs that are often greater than National Research Council (NRC) requirements.
