An experiment was conducted to assess the effects of different levels of extruded full fat soybean (EFFSB) on blood constituents, digestive organ weights, ileal digesta viscosity and performance of broiler chickens. Full-fat soybeans (FFSB), were extruded at high temperature short time (155°C, 15 s) with high pressure and shear forces at a feed plant and used at the levels of 0, 75, 150 and 225 g/kg in isocaloric and isonitrogenous starter, grower and finisher diets. One hundred and 90 2 d-old Ross 308 male broiler chicks were allocated to 4 dietary treatments with 4 replicates of 12 birds each. Performance criteria were recorded weekly. Blood samples of one bird from each replicate were taken via wing vein and percentage of oxygen saturation (SO2%) measured with gasometric system on d 18. One bird from each replicate was slaughtered, digestive organs weighed and ileal digesta was collected to determine the viscosity on d 21. All data was analyzed using GLM procedure of SAS (9.1). The blood gasometry results showed that percentage of oxygen saturation in blood (SO2%) of control birds was significantly (P < 0.05) higher than those fed diet contained high level of EFFSB (69.83% vs. 64.43), showing that high level of EFFSB in diet, can affect blood oxygen saturation in chicks. With increasing the level of EFFSB in diet up to 225 g/kg, total body weight gain (BWG) reduced significantly (P < 0.05) but feed conversion ratio (FCR) and production number (PN) were similar in birds fed different diets. The pancreas to live bird weight increased significantly (P < 0.05) in birds fed diet contained high level of EFFSB as compared with control ones (0.420 vs. 0.502%), but gizzard, proventriculus, small intestine, ceca, liver and abdominal fat to live bird weight were similar in all birds (P > 0.05). High levels of EFFSB in diet, did not affect ileal digesta viscosity in chicks (P > 0.05). It is concluded that addition of EFFSB up to 225 g/kg diet did not have negative effects on broiler performance and ileal digeta viscosity but influenced blood SO2% and pancreas weight.
