Relationship between the incidence of phosphatic urinary calculi and mineral metabolism was observed in goats fed a high phosphorus diet. A basal diet and alfalfa hay cube were given to 6 goats (group B), and hay cube and a calculogenic diet (the basal diet supplemented with K_2HPO_4) to other 6 goats (group C) for 2 months. Urinary calculi were produced in 5 goats of group C (obstructive urolithiasis in one goat and nonobstructive calculi in 4 goats), but in no goats of group B. Group C presented a higher urinary P level and lower urinary Mg, Na and Cl levels than group B. There was little difference in urinary pH, Ca and K levels between the two groups. Serum mineral levels showed little difference between the two groups, except the inorganic P level which exhibited a transient increase in group C. The serum urea level showed a progressive increase in group C during the experimental period. In balance trials, the retention of Mg, P and K was higher and that of Na lower in group C than in group B. It was confirmed that the dietary supplement of K_2HPO_4 caused some alteration in Mg, Cl and Na metabolism and serum urea level in addition to changes in P and K metabolism. It seemed that especially changes in P, Cl and Mg metabolism might be related to the incidence of urinary calculi in goats.
