Abstract COMPARISON OF PURINE DERIVATIVES AND CREATININE IN PLASMA AND URINE BETWEEN LOCAL CATTLE AND BUFFALOES IN VIETNAM In Experiment I, 4 female swamp buffaloes and 4 local cattle fed with the diet based on young maize and rice straw (80/20), and in experiment II, the same number and types of animals as in Experiment I were fed with the diet based on rice straw and rice bran (70/30). The animals were fed twice a day with the diets at 40, 60, 80, 95% of ad libitum intake. The digestibility of nutrients and N excretion were similar for cattle and buffaloes. The purine derivative:creatinine ratio (PDC) index was significantly affected by the level of feed intake (P
