CALCIUM AND STRONTIUM METABOLISM IN JAPANESE AND BOBWHITE QUAIL1 FRANK R. MRAZ Agricultural Research Laboratory of The University of Tennessee, Oak Ridge, Tennessee* (Received for publication March 14, 1969)

The use of Japanese quail (Coturnix coturnix japonica) as laboratory animals in biomedical and poultry research is increasing due to their small size and rapid maturity. This rapid maturity (6 weeks from hatching) introduces the question of how comparable the Japanese is to the Bob white (Colinus virginianus) quail (maturing at 5 to 6 months of age). During growth, an element of considerable importance and one bound to be affected by 1

the attainment of sexual maturity is calcium. Strontium is an element biologically similar to calcium and of comparable importance from the viewpoint of a radioactive contamination of the environment. This report will provide a comparison of strontium and calcium biological halflives and uptakes in immature Bobwhite and Japanese quail at different ages. METHODS

Twenty-five microcuries of 46Ca (1 mg. Ca) or 89Sr (carrier-free) in chloride form were administered orally to Bobwhite and Japanese quail before their first feeding. At periodic intervals after dosing (Fig. 1), 5 birds were sacrificed and a tibia removed from each for radionuclide deter-

hematocrit 32-35), although the immunologic response was almost completely suppressed (results to be published elsewhere). By the end of the 5th week the altitude treated chicks reached in size and general appearance the ground level controls. Mortality among the surviving chicks was 7%, compared to 4% for ground level controls. These preliminary experiments show that even a short term (24-48 hours) altitude exposure may significantly reduce the hatchability of eggs and causes hematologic and physiologic changes. The observed results warrant detailed investigation of these phenomena.

The biological half-life of strontium in the tibia of Japanese and Bobwhite quail between 1 and 56 days of age was about 20 days (Fig. 1), starting with about 2 percent of the administered oral dosage of 89 Sr one day after dosing. This was comparable to that in White Leghorn chicks except that 4 percent of the 89Sr was present one day after dosing (Mraz, 1966). The biological half-life of calcium in quail was about 40 days with an initial uptake by the tibia of 4 percent of the 46Ca one day after dosing. This percentage was twice that of 89Sr. The day-old quail chicks deposited more 45Ca and 89Sr in the tibia than did any of the older birds (Table 1). The fact that there was no feed in their digestive tracts to dilute the radionuclides contributed to this higher level. Deposition of the radionuclides in

the tibia of Bob whites was higher than that in Japanese quail after 3 weeks of age and was not influenced by sex over the 16week period. The influence of egg production in the Japanese quail was reflected in the increased 45Ca and 89Sr deposition in tibia of laying females over that found in males at 8 weeks of age and continued for those observed at 10 and 12 weeks of age. More of the radionuclides were deposited in the tibia of Bobwhite than male Japanese quail because they were still in the state of skeletal growth. It would appear that the biological half-lives of calcium and strontium in both
