This study was conducted to evaluate the nutrient retention of treated sugarcane bark scrapping fermented with rumen liquor (TSBS) on the broiler chickens. Six experimental diets coded as T1 (0%), T2(7.5%), T3(15%) for 4 days’ fermentation and T4(0%), T5(7.5) and T6(15%) for 8 days. T1 (0%) and T4 (0%) are the control in both 4 and 8days fermentation. The feed formulation was compounded such that TSBS replaced maize at 0%, 7.5% and 15% levels respectively in broiler finisher diet.  A total of one hundred and eighty (180) birds of four (4) weeks old broilers were randomly allotted into six treatment groups, each treatment had three replicates in a 2x3 factorial in a randomized experimental design. The facal sample was collected for 7 days at the end of experiment.  Results on nutrient retention of the birds fed TSBS showed that the dietary levels had significant effect (P<0.05) on digestibility efficiency of dry matter, crude protein, crude fibre, ash, and N.F.E retention. However, no significant (P>0.05) difference was observed in ether extract (EE) across the treatments measured. Fermentation days (4 and 8 days) had no significant (P>0.05) effect on digestibility efficiency of all the parameters measured except crude fibre and ash retention. However, interaction of fermentation days and level of TSBS in the diet significantly (P<0.05) affect all the parameters measured except ether extract retention. The interaction between 4 and 8 days shows that irrespective of the levels of inclusion of TSBS 0%, 7.5% and 15% and number of days of fermentation 4 and 8 days, the birds performed well. There was no significant (P>0.05) effect notice from the inclusion of 0%: 4days fermentation and the same for 0%: 8days in all the parameters measured in the feed trials.  In 7.5%: 4days, 7.5%:8 days, 15%:4 days, 15%: 8days show also no significant (P>0.05) difference in the experiment. The interaction on the nutrient retention show that there was significant different (P<0.05) observed in the broiler fed TSBS. The study shows that there was no significant different between 4 and 8 days fermentation, therefore 4 days’ fermentation is recommended to use to avoid time taken and stress in fermentation for longer period.
