The present trial was investigated the dietary effect of Azomite with low energy on growth, carcass and biochemical indexes in broiler chickens. A total of 180 AA broiler chicks were randomly allotted in to three treatment groups with six replicates and 10 birds/replicate: Control fed a basal diet, (2) Low ME fed (basal diet -100kcal kg1 (3) AZO-0.25 fed (Low ME +AZO-0.25). The results showed that, birds fed diet with AZO-0.25 had higher average daily gain (ADG) than that in Low ME group (P>0.05), while feed conversion ratio (FCR) was lower (P>0.05) compared to Low ME. Percentage of eviscerated carcass, breast muscle and leg muscle were higher significantly (P<0.05) in the AZO-0.25 than Low ME. Serum TP, IgG and CT levels significantly (P<0.05) higher in AZO-0.25 than Low ME. Overall, 0.25% Azomite showed positive effect on growth and carcass performance and it could compensate the negative effect of low-energy diet for broiler chickens by improving the digestion and utilization of nutrients.

1. The efficiency of food conversion by pullets and yearlings fed on high- and low-energy diets has been determined.2. Egg production was slightly higher by birds fed the low-energy diet for both pullets and yearling hens; pullets laid more eggs than yearling hens.3. For each age, the gross food intake was greater for birds fed the low-energy diet; the consumptions of digestible protein, non-protein digestible energy and metabolizable energy were the same for both diets and both ages of bird.4. The food cost per dozen eggs was slightly greater in the yearling year when the cost of rearing the pullets was ignored, and about the same when it was included.5. The efficiency of utilization of digestible energy and protein showed only a slight decrease from the pullet to the yearling year.6. The variation in the composition and digestibility of eighteen consecutive mixes of the highenergy diet and twenty-five of the low-energy diet was: crude protein 2%, non-protein digestible energy 5% and metabolizable energy 0·4 kg. cal./g. The digestibility of the crude protein and oil was 87%, for both diets; carbohydrates were 81% digestible in the high-energy diet and 59% in the low-energy diet.
