This study was conducted in a 4&times;2 factorial arrangement with 8 treatment and 3 replicates of 11 broiler chicks per each replicate in a completely randomized design. The experimental treatments were four substitution levels of SBM (0, 25, 50 and 75 percent) with ESB and two levels of vitamin E supplementation (42 and 75 IU/kg of diet). Results showed the effects of different substitution levels of SBM with ESB on production traits like feed intake, weight gain and feed conversion ratio as well as some carcass characteristics (breast muscle, thighs and liver as a percentage of live weight) was not significant. A significant interaction effect was found between levels of SBM substitution with ESB and vitamin E on weight gain at 42 days of age (P<0.05). Effects of substitution of SBM with ESB on percentage of pancreas weight was significant (P<0.05) as with increasing substitution levels the pancreas weight also increased. Effects of vitamin E on all the traits was significant (P<0.05) but carcass traits was not significantly affected by vitamin E</span><span dir="rtl"></span><span dir="rtl"></span><span 11pt="" b="" black="" calibri="" color:="" dir="rtl" en-us="" fa="" font-size:="" mso-ansi-language:="" mso-ascii-font-family:="" mso-bidi-language:="" mso-fareast-font-family:="" mso-fareast-language:="" mso-hansi-font-family:="" new="" style="LINE-HEIGHT: 115% FONT-FAMILY: " times=""><span dir="rtl"></span><span dir="rtl"></span> </span><span 11pt="" b="" black="" calibri="" color:="" en-us="" font-size:="" mso-ansi-language:="" mso-bidi-font-family:="" mso-bidi-language:="" mso-fareast-font-family:="" mso-fareast-language:="" new="" style="LINE-HEIGHT: 115% FONT-FAMILY: " times="">levels (P>0.05).</span> دانه کامل سویا, اکسترود, ویتامین E, عملکرد, جوجه گوشتی Whole soybean, Extrud,Vitamin E, Performance, Broiler 35 43 http://rap.sanru.ac.ir/browse.php?a_code=A-10-1-99&slc_lang=fa&sid=1 Mohammad Moradi محمد مرادی 100319475328460010225 100319475328460010225 Yes University of Gonbad Kavous دانشگاه گنبد کاووس Shahriar Maghsoudlou شهریار مقصودلو 100319475328460010226 100319475328460010226 No University of Gonbad Kavous دانشگاه گنبد کاووس Faramarz Rostami فرامرز رستمی 100319475328460010227 100319475328460010227 No University of Gonbad Kavous دانشگاه گنبد کاووس Yousef Mostafalou یوسف مصطفی لو 100319475328460010228 100319475328460010228 No University of Gonbad Kavous دانشگاه گنبد کاووس
