Abstract

This research was carried out to investigate the effects of diet added with Bacillus magaterium 1259 (BM1259) on concentration of nitrogen containing compounds in excreta of laying hens.A total of five hundred and seventy-six 300-day-old healthy Hyline brown laying hens with similar laying rate were randomly assigned to six groups with six replicates per group and sixteen hens per replicate.The control group was fed a basal diet, while the other groups were fed basal diet added with BM1259 of 100, 150, 200, 250 and 300 mg/kg, respectively.This test lasted for 42 d.The result showed as follows: 1) diet added with BM1259 significantly increased average egg weight (P<0.05), and significantly affected laying rate (P<0.01), and significantly decreased the ratio of feed to egg (P<0.01).Furthermore, the optimal group was observed in 100 mg/kg group.2) Diet added with BM1259 significantly decreased concentration of urea nitrogen and urease activity in excreta (P<0.01), and significantly decreased concentrate of uric acid in excreta (P<0.05).It suggests that diet added with BM1259 can improve performance and decrease the concentration of nitrogen containing compounds in excreta of laying hens.
