This study aims to determine the effect of the use of fermented corn straw (FCS) as a substitute for rice bran on cross breed native chicken productivity. The research method used was a field experiment using a Completely Randomized Design (CRD) with 5 treatments and 5 replications so that there were 25 experimental units. Each test consisted of 10 chicks, so that the number of cross breed native chickens used was 250. Cross breed native chicken basal feed is prepared based on the nutritional needs of cross breed native chicken, starter and finisher periods. The treatment given to livestock is P0 = 100% Basal Feed without fermented corn straw, P1 = 95% P0 + 5% FCS of total bran in the feed, P2 = 90% P0 + 10% FCS of total rice bran in feed , P3 = 85% P0 + 15% FCS of total rice bran in feed, P4 = 80% P0 + 20% FCS of total rice bran in feed . Parameters observed include: Feed Consumption (g / head / day), Weight gain (g / head / day), Feed Conversion and Income Over Feed Cost (IOFC). The data obtained were analyzed using analysis of variance (ANOVA) and continued with Duncan's Multiple Range Test. The results of the analysis of variance showed that the treatment of the use of fermented corn straw instead of rice bran in cross breed native chicken feed had a very significant effect (P <0.01) on feed consumption, weigh gain, feed conversion and IOFC. Discussion, it can be concluded that the replacement of bran with corn straw fermentation to the extent of 10% to produce performan good on cross breed chicken value high IOFC.
