EFFECTS OF DIFFERENT LEVEL BIOPOWDER ON GROWTH PERFORMANCE,AND BIOCHEMICAL PARAMETERS OF BLOOD IN BROILERS

A study was conducted to assess the effects of different level biopowder on growth performance,and biochemical parameters of blood in broilers.A total of 720,one-day-old Arbor Acres broiler chicks were used in this study.Broilers were randomly allotted to 6 treatmentseach consisted of 3 replications of 40 chickens.Dietary treatments were as follows:(Ⅰ)positive control(PC),(Ⅱ)negative control(NC),(Ⅲ)PC+ 60 mg/kg biopowder,(Ⅳ)PC+ 120 mg/kg Biopowder,(Ⅴ)PC+ 240 mg/kg Biopowder,(Ⅵ)NC+ 120 mg/kg biopowder.The result of this experiment indicated: at 21 and 42 days of age,BW in the Biopowdergroup was significantly higher(P0.05) and urea nitrogenwas lower(P0.05) than that in NC,but no differences in the total cholesteroland triglyceride(P0.05).At 21 days of age,urea nitrogenin group Ⅲ and groupⅣ were significantly lower(P0.05)than that in PC,whereas no significant differences in the total cholesteroland triglyceride(P0.05).The same conditionwas found in the group Ⅴ at 42 days of age.It was concluded that biopowdercould improve the growth performance,and decrease the urea nitrogenof blood in broilers.There was no difference in the total cholesteroland triglyceride.
