Development of bone mineralization and body composition of replacement gilts fed a calcium and phosphorus depletion and repletion strategy

•Required time to recover from bone mineral deficit was verified in replacement gilt.•Within 2 weeks, bone mineral of 60 kg gilt decreased by deficient dietary Ca and P.•Within 4 weeks, bone mineral of 100 kg gilt recovered by adequate dietary Ca and P.•Within 2 weeks, bone mineral of 100 kg gilt recovered by excessive dietary Ca and P.•Finisher diet without mineral P was no concern for late selected replacement gilt.
