Three experiments had been carried through where the first one had the objective to evaluate the nutricional and energetic value of the guava residue (RG) and of the tomato (RT), the variation of the chemical composition, as the time of collection, and the effect of the age on the values of energy of these residues. The values of chemical composition RG and RT had varied when it comes to the time of the collection, presenting high quantities of gross fiber. The age of the birds did not influence the values of EMA, EMAn e CMEB of RG, while for the RT there was influence on the EMA e CMEB, but there was not for the EMAn. The second and the third experiments had the objective of evaluate the effect of guava and tomato residues inclusion, respectively, on the productive performance of cut down chicken. The results of productive performance (fodder consumption, weight gain, alimentary conversion and carcass income) had not been meaningful, when the different levels of guava inclusion residue and the fodder reference to 42 days were compared. However the productive performances observations with the use of tomato residues reveal inferiors results with the inclusion of rising residues levels, especially on 1 to 28 days of age period and on total period, there was not meaningful effect to the carcass income. According to the present research it is recommended up to 12% of residue inclusion in cut down chicken fodder, on 1 to 42 days of age period, however, the tomato residue can be included up to 20 % in cut down chicken fodder in phases of 28 days of age, so that it does not occur damages in the cut down chicken productive performance.
