Resumo: 	We assessed the extent to which the removal of fat source, and consequently its compounds, such as linoleic acid, can affect the performance of broilers. We used 600 male Cobb 500 day old chicks. The birds were distributed in a completely randomized experimental design, with five treatments and six replicates of 20 birds each. The treatments were: (T1) diet - positive control (PC), which met the nutritional needs; (T2) diet - negative control (CN), a reduction of 100kcal/kg and low linoleic acid content; (T3): diet - negative control reformulated for low linoleic acid content and a set of Quantum phytase XT and Econase XT 25 (BAL + QFit-Eco), (T4): diet - negative control reformulated, with the percentage of linoleic acid adjusted to an intermediate value between the value of the diet and diet CP and CN to use a set of Quantum phytase XT and XT Econase 25 (IAL + QFit-Eco) and (T5): diet - negative control reformulated, with the percentage of linoleic acid adjusted to a value similar to that of the positive control diet and joint use of Quantum phytase XT and XT Econase 25 (AAL + QFit-Eco). The joint use of Quantum Phytase and Econase promoted improvement in the performance of broilers from 1 to 21 days. The greatest weight gain was obtained with diets containing percentages of total fat and linoleic acids. Dietary supplementation with enzymes resulted in higher levels of calcium in the tibia, whatever the percentage of linoleic studied.
