【 摘 要 】

The study was performed to evaluate the effects of wheat- distillers dried grain with soluble (DDGS) levels onperformance, carcass- characteristics, lymphoid organs and antibody titer against Avian Influenza and NewcastleDisease. A total of 144 day old broiler chicks (Ross 308) were randomly distributed between 3 treatments with 4replicates and 12 chicks per each replication. The treatments included: control diet without wheat DDGS (A); 3, 4, 6and 7% wheat-DDGS in starter, grower and finisher 1 and 2 phases respectively (B); 6, 8, 12 and 14% wheat-DDGSin starter, grower and finisher 1 and 2 phases respectively (C). Results showed that body weight at 50 d, daily weightgain at 25-39, 39-50 and 9-50 days significantly decreased C treatment (P˂0.05). The feed intake at 16-25 dsignificantly decreased by C treatment (P˂0.05). The feed conversion ratio at 25-39, 39-50 and 9-50 days in Ctreatment significantly decreased compare to control group (P˂0.05). The percentage of carcass, heart, gizzard andileum significantly decreased by C treatment (P˂0.05). Also, jejunum weight percentage in B and C treatmentscompare to control group significantly increased (P˂0.05). As a conclusion, using incremental levels of wheatDDGS (3, 4, 6 and 7%) in starter, grower, finisher 1 and 2 phases did not make significant change on broilers;performance. On the other hand, inclusion high levels of wheat-DDGS (12 and 14%) in finisher 1 and 2 phasesdecreased broilers’ performance (P˂0.05).
