Diet components are one of the determination factors for changing of morphology of small intestines which lead to a change in digestien and absorption of nutritiond subs tonces.To study the histomorphometric changes of small intestine due to hull- less barley food diets in poultry, 20, of 70 weeks old healthy Road Island Red cocks were selected and divided equally into 2 experimental groups and fed with hull less barley, and commonly usual diet (control). Feeding was gradually and by adding the experimental food to the commonly used diet through one week. At the end of the week, all animals starved for 24 hrs and then fed with experimental diets for following week. At the end all animals were weighted and sacrificed after 24 hrs of starving. excreta viscosity and crude diet energy, crude excreta energy and metabolisable energy were measured and the data were analyzed using Duncan method. transverse sections from small intestine were successively cut with 2cm intervals and fixed with 10% buffered formalin. Routine histological laboratory methods were used and sections were studied under light microscope. Heights and width of the villi and dept of the crypts and goblet cells number were measured. Data's were statistically analyzed by ANOVA test. Results showed: increasing in viscosity , increasing the villus heights (p<0.001), villus width (p=0.002) and crypt depth (p<0.001) and number of goblet cells (p<0.001) in jejunum, decreasing in height of the villi (p<0.001) and increasing in crypt dept (p<0.001) and goblet cells number (p=0.04) in the duodenum and increasing of the crypt dept (p=0.004) in the ileum were observed respected to the control.
