[Method] A total of 480 one-day-old 817 broilers were selected. They were randomly divided into four groups with different paddings, and each group was in triplicate. The weights of broilers and feed were weighed weekly. The growth performance of broilers was determined. On day 30, the ammonia concentra- tions in broiler houses were determined. On day 35, 6 broilers were randomly se- lected from each group, and their vein blood was sampled. In the sampled vein blood, the concentrations of ammonia, glucose, globulin, serum total protein and urea nitrogen were determined. [Result] There were significant differences in ammo- nia concentration among broiler houses laid with different paddings （P〈0.05）. The ammonia concentration in group 1 was significantly lower than those in group 3 and group 4 （P〈0.05）. No significant difference was found in ammonia concentrations in broiler houses between group 2 and group 3 （P〉0.05）. The ammonia concentration in group 4 was significantly higher than those in group1, group 2 and group 3 （,0〈 0.05）. There were also significant differences in blood indicators among different groups （P〈0.05）. The blood ammonia, blood glucose and serum urea nitrogen con- centrations in group 1 were significantly lower than those in other groups （P〈0.05）, the serum total protein concentration was significantly higher than those in group 3 and group 4 （P〈0.05）, and the serum globulin concentration was significantly higher than those in group 2, group 3 and group 4 （P〈0.05）. Significant differences were observed in feed intake, body weight gain and slaughter weight between different groups （P〈0.05）, but there were no significant differences in feed to grain ratio （P〉 0.05）. [Conclusion] Under the experimental conditions, the padding of Chinese medicine residue showed better effect on reducing ammonia concentration in broiler house, which was conducive to play of production potential of broilers.展开更多
