1. A combination of balance and isotope techniques was used to determine the influence of phosphorus depletion on the size of the exchangeable calcium pool and on the rates of Ca deposition in and removal from the whole skeleton of sheep. 2. The exchangeable Ca pool was reduced in size in the depleted sheep to approximately 50% of that in the controls. 3. The rates of Ca deposition in and removal from bone were reduced by P depletion and the rate of Ca transfer from the pool was reduced slightly. 4. The turnover rates of the exchangeable Ca pool and bone Ca in sheep appear to be similar to values published for man.

The flow of calcium and phosphorus to the proximal duodenum was measured over 22 24-hr periods in sheep fitted with re-entrant duodenal cannulae. The sheep were offered one of six diets in a ground and pelleted form supplying 1.4–30 g of nitrogen per day from three different protein sources. The estimated metabolizable energy content of the diets was 1.9 or 1.3 Mcal/kg. The diets supplied 2.0–5.8 g of calcium per day and 2.2–3.3 g of phosphorus per day. Between 49.9% and 61.2% of the dietary calcium intake appeared at the duodenum in the sheep given all diets except the one supplying 1.4 g of nitrogen per day, where the value was 98.5%. There were highly significant correlations between the daily calcium intake and the flow of calcium to the duodenum, the excretion of calcium in the faeces, the retention of calcium and the calcium content of the rumen. Between 85.0 and 119.1% of the daily phosphorus intake appeared at the duodenum in the sheep given all six diets. The flow of phosphorus was correlated with the dietary phosphorus intake. There were significant correlations between the flow of calcium and phosphorus to the duodenum and, also, their retention.
