The experiment was conducted to evaluate the effects of either housing types, mechanical ventilation and natural ventilation or soybean oil supplementation at 1 and 3% levels for layers. The experiment was designed in 2 x 2 factorial arrangements and conducted for three months. One hundred and forty 43-weeks laying old Isa Brown were assigned to four treatments. Layers kept in mechanical ventilation significantly increased (P0.01) egg production (93%) compared with that of natural ventilation cage (76.76%). Dietary supplementation of 1% soybean oil had higher egg production (85.19%) than that of 3% soybean oil (82.57%), but it was not statistically different (P
