0.05). Also different amounts of threonine not influenced on cell-mediated immune response and antibody response versus SRBC in 7 days after injection in native turkeys (P>0.05). However, in secondry challenge, treatments containing 0.85 and 1.15 % threonine had highest antibody concentration versus SRBC and had significant difference with groups of 0.95 % threonine (P<0.05). Different levels of CP and Thr amino acid had not significant effect on glucose, cholesterol, triglyceride, albumin, HDL, VLDL and LDL concentration (P>0.05), However level of 1.05 of threonine significantly increased serum total protein and uric acid concentrations in serum native turkeys (P<0.05). Except of uric acid, any interaction effect not observed between CP and Thr in measured parameters(P>.05). Results of present study generally indicated that supplementation of Thr amino acid to diet could be improve humoral immune response and increase serum uric acid level in native turkeys, However different amounts of CP had not affect on this parameters.]]>

0.05). Cholesterol level in treatment G3 on days 14 and 21, and treatments G4 and G5 on days 7, 14 and 21 was significantly reduced (P <0.05). Triglyceride level in treatment G2 on day 21 and treatment G3 on days 14 and 21 and G4 and G5 on days 7, 14 and 21 significantly decreased (P<0.05). It can be concluded that sub-lethal concentrations of silver nanoparticles, has a relative impact on blood factors and serum biochemical parameters, in addition to the effect on stress responses, and we should be cautious in the use of these substances in aquaculture.]]>

0.05) than control group in all period (1 to 49 days). However, feed intake and feed conversion ratio in chicks with feed restriction significantly decreased (P<0.01) compared to control treatment. With using feed restriction relative weight of abdominal fat significantly decreased (P<0.01) in 49 days of age. However experimental treatments not influence (P>0.05) on relative weight of hot carcass, breast and thigh muscles. Feed restriction treatments among not affect on gut morphology in 28 days of age. In general, the results of this study showed that apply of quantitative feed restriction in starter period could be keep bird performance without any harmful effect.]]>
