ABSTRACT

Present study was carried out to investigate the effect of azomite (AZO) on the growth performance, nutrient availability, intestinal enzymes activity, immune function, and bone mineralization of broiler chickens. A total of 240-day old male chicks were randomly assigned into comprising four treatments with six replicates (n=10), which included control (basal diet), control +0.25% AZO, control + 0.50% AZO and control + kitasamycin (as AGPs). The results indicate that LBGW, ADG and FCR was significantly (P<0.05) improved in AZO 0.25% and 0.50% than the control. Eviscerated (EV), breast muscle (BM) and leg muscle (LM) were significantly (P<0.05) higher in the AZO 0.50% treated groups than control. Digestibility of DM, CP, AME, Ca and P digestibility significant (P<0.05) higher in AZO 0.25% and 0.50% dietary treatments. Moreover, jejunal amylase and trypsin activity were improved in AZO 0.25% and 0.50% supplemented groups. CREAT was significantly increased in AZO 0.50% treatment, while IgG was significantly improved in AZO 0.25% treatment. Tibia diameter (TD), tibia breaking strength (TBS) were numerical higher in AZO 0.25%, while Ca and P % was significantly (P<0.05) increased in Azomite 0.25% treatment. The results indicated that addition of azomite at the dose of 0.25% and 0.50% in the diet had beneficial effect on growth performance, retention of nutrients, digestive enzymes and bone mineralization.
