Calcium (Ca) is a major component of the skeleton in addition to being essential for growth and is imperative for bone mass development. Improvement in Ca absorption in Ca-deficient diets has been shown in human and rodent studies when nondigestible oligosaccharides have been consumed due to a modification of gastrointestinal conditions which increase mineral solubility. Because swine have been shown to be an excellent model for human nutrition research, an experiment was conducted to determine how a moderately Ca-deficient diet would affect gastrointestinal fermentation conditions, Ca and phosphorus (PHOS) digestibility, bone mineralization, and growth performance in nursery pigs; and if supplementation of nondigestible oligosaccharides would affect these same parameters. Results indicate that feeding young pigs a diet below recommended levels of Ca reduced colonic pH, increased apparent total-tract digestibility of Ca and PHOS, but had no impact on bone mineralization or overall pig performance. Supplementation of nondigestible oligosaccharides had inconsistent effects on colonic pH, and did not affect Ca or PHOS digestibility, bone mineralization, or overall pig performance.
