Abstract
FEINBERG, Hughes, and Scott (1937) have recently reported that the blood serum of laying hens shows a marked rise in inorganic phosphorus during the period of shell formation. This increase is ascribed to the liberation of inorganic phosphate when calcium is drawn from the calcium phosphate of the bones to be laid down as calcium carbonate in the shell.This view is substantiated by the findings of Deobold, Lease, Hart, and Halpin (1936) that about 10 percent of the bone of hens on a liberal calcium ration is available for shell formation and, further, by the work of Kyes and Potter (1934) in which it was demonstrated that pigeons in a laying condition showed ossification of the bone marrow while males and non-laying females did not.Common (1932, 1933, 1936), working with the excreta of hens, offers a similar explanation.
