“…The total dietary Ca and P contents used by the latter investigator were not specified. In contrast, Arscott et al (1962) observed a significant increase in plasma inorganic P when Ca was increased from 22-5 to 30-0 g/kg diet and our results agree with this observation; indicating that plasma P is positively and linearly related to dietary Ca. These observations suggest that additional P is absorbed as dietary Ca increases.…”

“…Insufficient dietary Ca causes decreased egg shell strength and thickness in the laying hen (Arscott et al, 1962;Mehring, 1965), and bone depletion, increased bone fragility (Rowland et al, 1968) and decreased egg production can occur (Mehring, 1965). High dietary P contents may also decrease egg production or shell quality, or both (Harms et al, 1965;Taylor, 1965;Connor and Barram, 1972).…”

1. The effects of different dietary concentrations of calcium (24 to 56-9 g/kg) and phosphorus (4-5 to 14-2 g/kg) on production and some aspects of metabolism were studied in laying hens. 2. Treatments did not affect egg numbers, food consumption, conversion efficiency of food to egg, bodyweight gain or mortality. 3. Increasing dietary calcium (Ca) significantly increased plasma Ca and inorganic phosphorus (P), breaking strength at the radius and egg specific gravity and significantly decreased plasma alkaline phosphatase and egg weight. 4. Increasing dietary phosphorus increased plasma P and decreased egg specific gravity significantly. 5. Plasma Ca, P and alkaline phosphatase and radius breaking strength were suitable indices of the Ca status of the hens.

“…Egg shell quality has been reported to be improved when ascorbic acid was added to practical laying hen diets Moreng, 1958, 1959;Thornton, 1960a and b;ElBoushy ^ al.. 1968) but the results are inconsistent (Heywang and Kemmerer, 1955;Arscott et al, 1962;Hunt and Aitken, 1962;Rumsey, 1969) and egg shell may be unaffected. Sullivan and Gehle (1962) reported a nonsignificant decrease in plasma calcium in laying hens supplemented with ascorbic acid.…”

“…Because the phosphorus content of the shell is very low (44), it is likely that phosphorus exerts its effect on shell formation by affecting bone mineral metabolism. Excessive levels of phosphorus have also been observed to cause a reduction in shell thickness (45,46). Although it seemed likely that excess phosphorus was interfering with calcium metabolism, little evidence was obtained to support this hypothesis.…”
