  The main objective of this trial was to find out the best metabolizable energy (ME) consumption in order to improve the egg quality. 288 laying hens Hissex Brown aging 30 weeks were randomly assigned in a 3x3 factorial design with nine treatments and four replications each, being respectively 280, 300 and 320 kcal/bird/day and three levels of oil (0.00, 0.75 and 1.5 g/day). Daily feed intake was based on 115, 110 and 105 g/bird/day to achieve the desirable levels of ME and oil. The rations were formulated to furnish the following amounts: protein 18g; Ca 42 g, total phosphorus 0.66; methionine 0.40 g;methionine+cystine 0.73 g and lysine 0.83. No significative statistical differences were detected (P>0.05) for mean egg weight (g) and specific gravity. There was significant quadratic effect of the energy consumption on the egg shell percentage (%), with decrease of the percentage among 280 and 300kcal of ME/bird/day and increase of the same among 300 and 320kcal of ME/bird/day, significant reduction of the albúmen percentage (%) and increase of consume and Haught Unit (UH) which decreased as daily the yolk percentage with the increase in the oil consumption energy intake increased (P<0.05). There was a significative interaction between energy and oil KEY WORDS: Egg quality, energy, semi heavy layers, vegetable oil.
