Abstract
This study investigated how to determine the quality of protein in diets and the renal disease of swines by raising 5 commercial feeds (16.71, 20.43, 21.83, 19.64 and 18.29%, respectively) to the 150 weanling pigs for 3 weeks. In the beginning, blood samplings were taken after feeding 3 days. Afer that, the samplings were taken every week after fasting (both water and feed) for 5 hours, then, blood urea and creatinine were analysed. The results demonstrated that the Urea-Creatinine Ratio of treatment 5 was the lowest, 9.80? 2.92, and the ADG was the highest (significantly different from treatment 1 and 4), 371.25 gram/day (P<0.05). On the other hand, the Urea-Creatinine Ratio of treatment I was the second lowest, 10.51±2.81, but the ADG was the significantly lowest, 245.82 gram/day (P<0.05) ; however, the Urea-Creatinine Ratio of the 5 treatments were not significantly different. (P>0.05)
