Abstract Avaliaram-se os níveis de energia metabolizável normalmente utilizados nas rações de frangos de corte, obtidos pela inclusão de óleos vegetais (soja, canola e palma) e seus efeitos sobre o perfil de ácidos graxos da pele e dos músculos da coxa e do peito, levando-se em consideração a linhagem e o sexo. Foram utilizados 2400 pintos de um dia, machos e fêmeas, das linhagens comerciais Hubbard e Avian Farms. As aves receberam ração inicial e final com níveis de energia metabolizável de 3050 e 3150kcal/kg, respectivamente, obtidos pela inclusão dos óleos vegetais, fornecedores de ácidos graxos, inclusive "ômega-3". Utilizou-se um delineamento inteiramente ao acaso em um arranjo fatorial com 16 tratamentos (4 rações × 2 sexos × 2 linhagens) com duas repetições cada. Diferenças entre médias foram testadas pela dms. Não houve efeito significativo da inclusão de óleos na ração sobre o perfil de ácidos graxos na carcaça. O mesmo ocorreu quanto ao efeito de sexo e de linhagem. An experiment was carried out with the objective of evaluating the effect of metabolizable energy levels, normally utilized in ration for broilers by addition of vegetable oils (soybean, rapeseed, and palm), on the profiles of fatty acids of the skin and meat of breast and thigh according sex and lineage, based on 2,400 one-day-old chicks, males and females, from Hubbard and Avian Farms. The fowls were given initial and finisher rations with metabolizable energy levels of 3,050 and 3,150kcal/kg, respectively, obtained by the inclusion of vegetable oils, which provided fatty acids, including "omega-3". The initial and finisher control rations were based on corn and soybean, without oil inclusion, with metabolizable energy levels of 2,900 and 3,000, respectively. A completely randomized design with factorial arrangement (4 rations × 2 sexes × 2 lines) and SMD test were used. No effects of sex, lineage and oil inclusion on carcass fatty acid profiles were observed.
