Abstract
In this experiment, effects of two phosphate solublizing bacteria as a novel probiotic on serum concentrations of cholesterol and triglyceride and performance factors were investigated. The experiment included 320 Ross broilers from 1 to 49 days of age. Birds were randomly allocated to 4 treatments, with 4 replicates of 20 birds. Treatments include T1.Negative Control (basal diet, with no added probiotic); T2 – Negative Control + Probiotic (in starter, grower and finisher); T3 – Negative Control + Probiotic (in grower and finisher) and T4 – Negative Control + Probiotic (in finisher).The results obtained in this experiment showed that the probiotic significantly increased body weight gain (p<0.05). Probiotic significantly improved feed conversion ratio (p<0.05). However, the probiotic supplementation did not affect on feed intake between treatments (p<0.05). In addition, results showed that probiotic caused significantly decrease on the serum cholesterol and triglyceride (p<0.05). Mean total cholesterol was significantly lower in the T2 fed group (p < 0.05) when compared to treatment without probiotic.
Key words: Probiotic, phosphate solublizing bacteria, cholesterol, broiler.
