This study aimed to find the effect of saline water on the growth performance and carcass characteristics of Tre chickens. A total of 150 Tre chickens was allotted in five treatments and three replicates per treatment. A completely randomized design was used for this study in which the birds from 4-14 weeks old had ad libitum access to feed and water in all treatments with five levels of salt (0, 0.2, 0.4, 0.6, and 0.8%). The results showed that the growth performance of Tre chicken was decreased when increased levels of salt in drinking water (P0.05). Small intestine weight was longer at control treatment while large intestine was longer at treatment of 0.2% salt. Additionally, all examined criteria were decreased significantly with 0.4, 0.6, and 0.8% of salt in drinking water (P
