A total of fifteen single comb white leg horn cockerels of uniform age and weight were procured and raised in metabolic cages which were used to conduct five trials at 0 and after 4, 8, 12 and 16 weeks of storage of rice polishing. Five force feeding trial were conducted, first trial was conducted by using fresh rice polishing considering 0 week of storage followed by four more force feeding trial after storage of 4, 8, 12, and 16 weeks of rice polishing using the same birds. The birds were fasted first for the period of 21h followed by force feeding of 20g of rice polishing with antioxidant to one an without antioxidant to an other group, a control/ fasting group was also kept to measure endogenous losses. After the period of 48h feces collection was performed for the determination of Apparent and True Metabolizable energy values. Along with the biological trials, laboratory assay of the rice polishing stored with and without antioxidant was conducted to measure the extent of rancidity in terms of Thiobarbituric Acid Value (Thiobarbituric Acid No.) with the help of spectrophotometer at 531 nm. The data obtained was analyzed by using complete randomized design which revealed that, increasing storage periods increased the TBA no. (P<0.05) in both the groups, while the AME and TME showed non significant (P>0.05) change before and after a specified storage periods. It was concluded that there is no effect of rancidity and storage on the nutritive value, AME and TME of Rice Polishing in poultry but TBA No. increases with the passage of storage time.
