Show Minerals Will Improve Quality of Egg Shells Improvement in shell texture of eggs can be made in many cases by providing the foods that supply the mineral properties contained in the shell itself. The shell of the egg contains about 90 per cent , calcium cal-cium carbonate and foodstuffs containing con-taining the minerals and vitamins necessary for shell production should help to increase the supply and bring about some improvement in shell quality. Shell-grit or oyster shell-grit provides pro-vides calcium carbonate, but without with-out vitamin D the hen may not be able to , convert sufficient quantities to meet the demands for bone and egg-shell formation. |
