Abstract:
1. 1. Duodenal calcium-binding protein (CaBP) and 25-hydroxycholecalciferol (25 HCC-1-hydroxylase) increased after the onset of gonadal activity, prior to egg laying. 2. 2. A further increase in CaBP and 25-HCC-1-hydroxylase occurred at the onset of egg laying. 3. 3. An arrest of egg production, induced by Nicarbazin, resulted in a decline in both CaBP and 25 HCC-1-hydroxylase, within 3-5 days. 4. 4. The increase in calcium absorption during the interval of shell calcification, within the egg formation cycle, was not associated with changes in either CaBP or 25 HCC-1-hydroxylase. The activity of the enzyme decreased after a one-day pause in egg laying. 5. 5. Comparable results were obtained with both chicken (Gallus domesticus) and Japanese quail (Coturnix coturnix japonica). © 1977.
