説明

This experiment was carried out to clarify the relation among the discharged amount of creatinine (Cr) in urine in 24h, the body weight (BW) and urine volume in 24h on pigs. Fifty-eight healthy Large White hogs (castrated male pigs), ranging from 30.5kg to 95.3kg of BW were used, and fed a diet in a daily amount of 3.5% to 4% of BW, containing 12.5% digestible crude protein and 3540kcal matabolizable energy/kg of diet throughout the experiment. Daily urine was collected continiously for 5 days and the daily urine volume and the concentration of Cr in urine in 24h were determined. There was a significant positive correlation between the BW (X: kg) and Cr in urine in 24h (Y: mg/d), and a linear regression line of Y=41.4 X-201.0 (R2=0.977, P<0.001) was obtained. The coefficient of variation of the 24h urine Cr during 5 days was small (4.8±2.6%).On the other hand, no significant correlation between the BW and quantity of urine in 24h, and in the relation between the urine Cr and urine volume in 24 h was observed. It is clear that the discharged amount of urine Cr in 24h in Large White hogs is determined by their BW.
