Mehdi Ghaderi Jouybari, Mohammad Ali Malbobi, Mehrdad Irani, Vahid Rezaei Pour


In this experiment, effects of two phosphate solublizing bacteria as a novel probiotic on performance factors and serum concentrations of cholesterol and triglyceride 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 (1) basal diet with no additives (control); (2) basal diet + 0.25% probiotic in starter, grower and finisher; (3) basal diet + 0.25% probiotic in grower and finisher; and (4) basal diet + 0.25% probiotic in finisher. The results obtained in this experiment showed that the probiotic significantly increased body weight gain and improved feed conversion ratio (P < 0.05). However, the probiotic supplementation did not affect 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).

Key words: Probiotic, phosphate solublizing bacteria, cholesterol, broiler.
