摘要： The present study investigated the effect of Azomite (AZO) on the growth performance, nutrient utilisation, and bone mineralisation of broilers fed low protein diet. A total number of 180 one-day-old male chicks were randomly distributed to three treatment groups having six replicates of 10 birds each. Experimental diets included; positive control (PC) with 21.5% CP (starter) and 19.0% CP (finisher), negative control (NC) with 2% lower CP than PC in each period and treatment group (AZO-0.25) in which NC was supplemented with 0.25% AZO. Azomite significantly (p < .05) improved live body weight, average daily gain and feed conversion ratio, but not the feed intake, as compared to NC. Eviscerated, breast muscle and leg muscle percentages were significantly (p < .05) higher in the birds fed AZO-0.25 than NC, while abdominal fat (AF) percentage was significantly (p > .05) higher in NC. Azomite improved the digestibility of dry matter (DM), crude protein (CP), apparent metabolisable energy (AME), calcium (Ca) and phosphorus (P) (p < .05) compared to the NC. Trypsin activity was increased (p < .05) in birds fed diet with AZO-0.25 compared with NC. Blood creatinine, growth hormone (GH) and calcitonin (CT) was also higher (p < .05) in birds supplemented with AZO-0.25. Treatment also affected (p < .05) the tibia breaking strength (TBS), ash, Ca and P contents. Overall, AZO improved the growth performance, nutrient utilisation and tibia mineralisation in broilers fed with low CP diet, which looks an economically promising approach.
