Background and Objective: The nutritive value of mao pomace includes a high concentration of organic acids, which can be exploited in broiler chicken production. The performance and economic characteristics were evaluated of broilers fed varying dietary levels of mao pomace. Materials and Methods: In total, 400 days old Cobb broilers were randomly allocated based on a completely randomized design into 4 treatments with 5 replications (20 birds/replicate). Dietary treatments consisted of (1) Basal diet (CON), (2) Basal diet+0.5 g kg1 of mao pomace from the juice industry (MPJ1), (3) Basal diet+1.0 g kg1 of mao pomace from the juice industry (MPJ2) and (4) Basal diet+1.5 g kg1 of mao pomace from the juice industry (MPJ3). Data were analyzed by general linear models, using a completely randomized design (CRD), the means were compared with Duncans test (p<0.05) using Tukeys test. Results: The results showed that the feed intake and feed conversion ratio were higher in MPJ2 (p<0.05) during age 7-14 days, whereas, viability was unaffected after dietary supplementation during the starter period (p>0.05). In addition, body weight gain, feed intake, average daily gain and production index were unaffected during age 15-42 days (p>0.05). The feed conversion ratio increased in MPJ2 during the overall period, whereas, viability improved in MPJ1, MPJ2 and MPJ3 during the overall period relative to the control (p<0.05). Moreover, the feed cost per gain and net profits per bird increased in MPJ3, whereas, the return of investment in comparison with the control group was significantly suppressed in MPJ2 (p<0.05). Conclusion: The MPJ-supplemented birds exhibited better viability and it was better to supplement the basal diet during age 7-14 days. Further detailed study is required on the mechanism and meat quality analysis in broilers.
