Different Levels

1. The daily retention of calcium, carbonate, phosphorus and chloride was studied using four birds and changing the calcium carbonate content of the ration every 5 days for 15 days.2. It was shown that high calcium diets result in a much lower retention of calcium and thin-shelled eggs are produced.3. Retention of calcium was higher in the laying than in the non-laying bird when calcium carbonate was fed.4. High calcium diets depressed the retention of phosphorus, and in one case the retention was negative, even when no eggs were laid. Laying birds gave negative values for retention because of the heavy phosphorus excretion associated with egg laying.5. High calcium diets also depressed the retention of chloride, and on occasion led to negative retention values.

Calcium And Phosphorus

1. Rats were given diets containing different amounts of calcium, phosphorus and lead.2. Pb retention was greatly increased when the diets contained less Ca or P than the minimum estimated requirement of the rat.3. The release of Pb already incorporated into the skeleton was inhibited by diets low in Ca but was not affected by diets low in P.4. The retention of Pb given intraperitoneally was not affected by dietary Ca or P.5. It can be concluded that dietary Ca and P influence the absorption of Pb by the gut and dietary Ca influences the metabolism of Pb in the bone.6. There were changes in the distribution of Pb among the tissues due to changes of dietary Ca.7. At low body concentrations, Pb probably affected skeletal growth.

A higher Ca-P intake during finishing, gestation and lactation periods increased (P < 0.05) the apparent absorption (g/day) of Ca and P during all three periods. Nutrient absorption appeared to differ for Lacombe and Yorkshire gilts. Key words: Calcium, phosphorus, nitrogen, absorption, gilts

Vitamin D3 Supplementation

A diet based on field peas and barley can satisfy the mineral requirements of growing pigs provided that calcium is supplemented at least to the level of dietary phosphorus present, and that vitamin D3 supplementation is greater than Agricultural Research Council recommendations. Bone fragility and lameness observed in pigs on a low calcium-low vitamin D3 diet was overcome by increasing either of these components, and this was accompanied by increased metacarpal ash and femur breaking strength. A similar response could also be produced by increasing dietary phosphorus levels. Plasma calcium and phosphate concentrations were significantly influenced by changes in the dietary calcium/phosphorus ratio, whereas vitamin D3 changes had a minimal influence. Parathyroid activity appeared to reflect the plasma calcium concentration. There did not appear to be any relationship between plasma concentrations and bone fragility or lameness.In order to ensure adequate bone development in pigs offered a diet of plant origin, vitamin D3 supplementation and elevation of dietary calcium to the level of total phosphorus present is a minimum requirement.
