The experimental desing was a completely randomized whit 6 treatments and 4 replications, in 24 portions of 10 birds per parcel. The treatments corresponded to 6 rations (T1-T6) in phase initial (1-21 days) and 6 rations (T1-T6) in phasem finish (22-42 days) characterized by substitution of corn meal in levels increase 0, 5, 10, 15, 20 e 25% by the molasse dried sugar-cane. The birds received water and free ration during the whole creation phase, being the iso-proteins and iso-calories rations. The variance analysis showed the 1 a 21 days significant differences for average gain weight (P<0,05), average consumption of ration (P<0,05) and average alimentary conversion (P<0,05) and the 22 a 42 days, the analysis of variance showed significant differences for gain in weight (P<0,01) and average alimentary conversion (P<0,05). There no difference significant on average consumption of ration (P>0,05) the 22 a 42 days of age. Results showed out that is possible to use molasse dried sugar-cane up to 8,3 % in broilers ration. It was concluded the level of 8,3 % of addition gave the best economical returns in the experimental conditions / Objetivou-se analisar os efeitos do uso de mel seco de cana (MSC) em ra??es de frangos de corte, bem como estudar a viabilidade econ?mica desta inclus?o. Duzentos e quarenta pintos de corte machos Ross, de 01 dia de idade, foram distribu?dos em um delineamento experimental inteiramente casualizado, com 6 tratamentos e 4 repeti??es por tratamento, em que cada uma deles inclu?a 10 animais. Os tratamentos constitu?ram no fornecimento de 6 dietas (T1-T6) na fase inicial (1-21 dias) e seis dietas (T1-T6) na fase final (22-42 dias), onde o milho foi substitu?do em n?veis crescentes 0, 5, 10, 15, 20 e 25 % pelo mel seco de cana-de-a??car. Todos os animais receberam ?gua e ra??o ad libitum durante o desenvolvimento da experi?ncia, sendo as ra??es iso-prot?icas e iso-cal?ricas. A an?lise de vari?ncia demonstrou que de 1 a 21 dias de idade teve diferen?a significativa para ganho de peso m?dio (P<0,05), consumo de ra??o m?dio (P<0,05) e convers?o alimentar m?dia (P<0,05) e de 22 a 42 dias de idade teve diferen?a significativa para ganho de peso m?dio (P<0,01) e convers?o alimentar m?dia (P<0,05). N?o houve diferen?a significativa para consumo alimentar m?dio de 22 a 42 dias de idade (P>0,05). Os resultados revelaram que em ra??es de frangos de corte, ? poss?vel a utiliza??o de mel seco de cana (MSC) em at? 8,3 %, com um melhor retorno econ?mico
