Research has been carried out, on sheep of Sardinian breed, in order to discover the apparent mineral ba lance in their food between the amount of Ca and P as opposed to that of Na. The fodder used was prepa red with by-products found in Sardinia. The rams used in the experiment, after a period of gradual habituation to the food, were transferred to special metabolism crates far a period of ten days. After a preliminary phase the experiment was divided into three successive trials using four rams at a time. In all three experiments, the pellets used were identical, except that the quantity of Na was varied: to be precise, 1.33% was added in the second experi ment and 2% in the third. The increase in the amount of Na in the fodder caused an increase, not only in the absorption of Na, but also in that of Ca, and, in the third experiment, of P. The variations found in the third experiment indicate an increase in the absorption of Na equal to 33.68%, of Ca equal to 4% and of P equal to 5%.
