Dietary effect of substituting mixed saw dust for wheat offal on internal organ and linear body measurement of broiler finisher was conducted using ninety (90) broilers. The broilers were allocated to three dietary treatments consisting of three (3) replicates of ten (10) birds in each replicate. Three dietary treatments were formulated with the mixed saw dust substituting wheat offal at 0%, 35 and 70% level of inclusion respectively. The experiment lasted for four (4) weeks. The experiment was arranged in a Completely Randomized Design (CRD). Data obtained was analyzed using ANOVA. At the end of the experiment, result showed that there were significant (p< 0.05) difference in the values recorded for the internal organ of broiler across the treatment. The highest liver weight (1.62%) was recorded for birds fed control diet, while the lowest liver weight (1.50%) was recorded for birds on T3. Birds on T1 and T2 had a liver value which is statistically similar and differs from birds on T3. The lowest value (0.40%) recorded for heart was observed in broiler fed with (35%) T2, while the highest heart value (0.50%) was recorded for broiler fed diet 3. The highest kidney weight (0.50%) was recorded for birds on control diet, while the lowest kidney weight (0.32%) was recorded for birds diet 2. Birds on diet 2 had the highest spleen weight, while the lowest spleen weight (0.00%) was recorded for birds on control diet. For linear body weight however, It was observed that the values recorded for all linear body parameters were significantly (P<0.05) differences across the dietary treatments, with the exception of body length, shank length and girth length which showed no significant differences across the dietary treatments. The highest value (2591.00g) of final live weight was noticed in birds fed control diet, while the lowest value (2394.00g) of final live weight was recorded for birds on treatment 3. There were significant (P<0.05) different in the value obtain for average weight gain across the dietary treatment. The value obtained fluctuates as the substitution level of mixed sawdust for wheat offal increased. The highest value (1313.00g) of weight gain was recorded for birds on control, while the lowest value (1119.00g) was obtained in birds on diet 2.It can be concluded that mixed saw dust can be given to birds without having any negative effects on the organ weight and the linear body measurement of broiler birds
