Storage of feed plays an important role in the economic and health aspect of livestock production. This study was conducted to investigate the effects of varying storage conditions (lit and dark room) on physical changes, occurrence of insects in stored feed, storage loss and nutrient composition of owner selected broiler finisher feeds. Bags of 25kg each of broiler finisher diets from four feed companies (A, B, C and D) were obtained on the day of production and were stored under two storage media (lit and dark room) for a period of 8 weeks. The experiment was arranged in a 4 x 2 factorial layout to form eight treatments with 5 replications. Feed colour, storage loss, occurrence of insects, and proximate analysis were carried out at 2 week intervals. Data generated were statistically analyzed by ANOVA technique in a 4 x 2 factorial design using PROC GLM procedure of SAS (2007). Storage temperature (27.27 oC and 26.65 oC for lit and dark room, respectively) and relative humidity (79.83% and 80.64% for lit and dark room, respectively) monitored were not significantly (p>0.05) different. Colour changes were observed in the feed from the 29th day of storage. By the 42nd day, presence of lesser grain borer (Rhyzopertha dominica F.) was observed in all the feeds. Appearance of frass, dusty particles and webbing were observed in feeds stored in lit room on 42nd day and those in dark room on 56th day. Storage loss (%) was reduced (p
