  1. aResults were expressed on dry-defatted weight basis of tibia
  2. bResults were expressed on ash weight basis of tibia
  3. cMeans were calculated on n = 5 replicates (one laying hens per replicate) per treatment
  4. d,eWithin comparisons, means in a column with no common superscripts differ significantly (P < 0.05)
