This experiment was carried out using 560 chicks to evaluate effects of different levels of Cation-Anion balance on perfor- mance, carcass quality characteristics, livability, production index and litter moisture in growing (21-42 days) Ross male broiler chickens. A completely randomized design, with seven treatments (150, 175, 200, 225, 250, 275 and 300 meq/kg) and four replicate was used. Results indicated no significant effects of treatments on feed consumption, feed conversion ratio and body weight in 42 day. Different cation-anion balance levels affected on body weight gain, that the highest and lowest values of body weight gain were observed when diets contained 200 and 150 meq/kg (P0.05), respect- ively. Different cation-anion balance levels had not significant effect on carcass, thigh, breast, liver, kidney and abdominal fat percentage of broiler chicks. Litter moisture in groups of 250 and 300 meq/kg were significantly (p0.05) higher than other groups at the age of 35, but there was no differences between groups at 42 days of age. Production index was improved using 200 meq/kg but with no significant difference than the other treatment was not significant. According to the results using 200 meq/kg can improve growth rate and reduce the feed cost per Kg of live weight in broilers. Key words: Dietary cation-anion balance, Broiler chicks, Performance, Carcass quality characteristics, Litter moisture
