One thousand and eighty DeKalb XL pullets were randomly allocated to nine treatments and arranged in a 3 x 3 factorial to determine the effects of three levels of dietary calcium (2.75, 3.75, and 4.25%) and three levels of dietary available phosphorus (.30, .40, and .50%) on eggshell quality and tibia weight, tibia breaking strength, tibia ash, and bone mineral content of pullets during peak production. Feed consumption increased as dietary calcium or phosphorus increased. Increasing dietary… Expand

TLDR
Eggshell quality, as measured by appearance, strength and thickness of eggshell, were influenced by dietary Ca content as expected (p<0.05) and suggested that aged laying hens require relatively higher level of Ca than required levels from current Korean feeding standards for poultry. Expand
INFLUENCE OF CALCIUM ON ENERGY CONSUMPTION AND EGG WEIGHT OF COMMERCIAL LEGHORNS
Abstract Several studies have demonstrated the influence of dietary calcium level on feed and energy intake. Because egg size is influenced by feed or energy intake, two experiments were conducted toExpand
Effect of different calcium sources and calcium intake on shell quality and bone characteristics of laying hens at sexual maturity and end of lay.
TLDR
It is concluded that calcium supplementation increases egg quality, mechanical properties of the bone and as a consequence, may be able to reduce the risk of broken bones at the end of laying period. Expand
Effect of Adding Different Dietary Calcium to Available Phosphorus Ratios on Productive Performance and Eggshell Quality of White Egg Layer Hens
TLDR
It was possible to conclude that the greatest calcium to available phosphorus ratio 13:1 was sufficient to maintain the productive performance and eggshell quality at the lowest cost of white egg layer hen from 44 to 52 wk of age. Expand
Effect of Adding Different Dietary Calcium to Available Phosphorus Ratios on Productive Performance and Eggshell Quality of White Egg Layer Hens
To establish the optimum dietary calcium to available phosphorus ratio for the best productive performance and eggshell quality of layer hens, a total of 160 laying hens, 44-wk-old were used to studyExpand
Calcium and available phosphorus levels for laying hens in second production cycle
TLDR
The diet containing 4.5% calcium improved feed conversion ratio per dozen eggs and eggshell quality and the lowest avP level fed (0.25%) is sufficient to maintain the performance and the egg quality of semi-heavy commercial layers after molting. Expand
Influence of supplemental phytase on calcium and phosphorus utilization in laying hens.
TLDR
Phytase supplementation completely overcame the adverse effects associated with low dietary P and significantly reduced the impact of low dietary Ca on hen performance. Expand
Influence of calcium and environmental temperature on performance of first-cycle (phase 1) commercial leghorns.
TLDR
It was concluded that Hy-Line W-36 hens could be fed diets containing as much as 5% Ca with no adverse effect on egg production, egg weight, or feed consumption and that hens housed at the lower environmental temperature had an increase in egg Weight, egg specific gravity, and feed consumption. Expand
Effect of supplementing microbial phytase in diets containing graded concentrations of calcium on performance, shell quality and bone mineral parameters in WL layers
TLDR
It is concluded that WL layers reared in open sided poultry houses in tropical climate require lower intake of Ca when the diets are supplemented with phytase compared to those fed withoutphytase, suggesting the inhibitory effect of higher dietary Ca concentrations on utilization of phytases phosphorus. Expand
Non-phytin phosphorus requirements of commercial broilers and White Leghorn layers
TLDR
It can be concluded that commercial broilers need about 4.4 g NPP kg - diet for better performance, whereas, White Leghorn layers need not more than 2.6 g N PP kg -1 diet to produce eggs with better egg size and shell quality. Expand

The influence of dietary phosphorus level on laying hen performance, egg shell quality, and various blood parameters.
TLDR
Hens consuming the diets containing .17, .23, and .30% phosphorus consumed significantly less feed, which resulted in poorer performance than hens fed diets supplemented with inorganic phosphorus. Expand
Influence of phase feeding available phosphorus on egg production characteristics, carcass phosphorus content, and serum inorganic phosphorus levels of three commercial layer strains.
TLDR
An experiment was conducted to obtain information on the concept of progressively decreasing dietary phosphorus levels (phase feeding) on the performance of three different commercial layer strains and found that efficiency of feed utilization was significantly superior for hens phase-fed AP compared with hens fed the other AP treatments. Expand
Calcium and its relationship to excess feed consumption, body weight, egg size, fat deposition, shell quality, and fatty liver hemorrhagic syndrome.
TLDR
It is concluded that overconsumption caused by feeding pullets or hens inadequate calcium had no beneficial effect on egg size or egg production and, depending on strain, increased liver fat, liver hemorrhage score, body weight, and fat pad weight. Expand
A Comparison of Continuous and Phased Levels of Dietary Phosphorus for Commercial Laying Hens
Abstract One hundred and forty hens of a commercial strain were allocated randomly to 7 treatment groups of 20 birds each at 20 weeks of age. Five treatment groups were assigned to ground yellowExpand
Influence of dietary phosphorus on shell quality 1
TLDR
Egg production was found to be improved in the birds fed the low phosphorus diets and birds housed on litter showed an inverse relationship between shell quality and the level of dietary phosphorus. Expand

TLDR
Data indicate that ESG and EW can be used to obtain an excellent estimate for SW and that treatment differences for shell quality were found to be minimal when adjusted for EW. Expand

TLDR
When maintained on tritiated 1,25-dihydroxyvitamin D 3, rats fed a low-phosphorus diet had somewhat higher levels of tritiations in the duodenum and plasma than rats on a normal-ph phosphorus diet. Expand

Effect of dietary phosphorus levels on porcine renal 25-hydroxyvitamin D-1 alpha- and 24R-hydroxylase activities and plasma 1,25-dihydroxyvitamin D3 concentration.
TLDR
The low P diet was associated with a prolonged elevation of renal 1 alpha-hydroxylase activity in spite of the presence of a pronounced hypercalcemia, and plasma alkaline phosphatase activity was two to four times higher in pigs fed the low P diets compared with pigs feeding the control diet.

Stimulation of 25-hydroxyvitamin D3-1alpha-hydroxylase by phosphate depletion.
TLDR
The ability of low phosphorus diets to stimulate the activity of the 25-hydroxyvitamin D3-1alpha-hydroxylase was tested in the chick and resulted in a marked increase in enzyme activity relative to chicks fed a normal phosphorus diet. Expand
