Comparative study of multilevel fish oil suplementation on production and carcass quality was conducted on twenty crossbred female pigs (Large White x Landrace x Duroc) with average weight of 31.77 kg. The pigs were arranged in a completely randomized design. Each group had five pigs weighting from 30-60 kg (Growing) and 60-90 kg (Finishing). They were assigned to a control, and three different diets containing 1, 2 and 3 percent tuna oil. The results indicated that the group that had 1 percent dietary fish oil, showed a higher production performance than that of the control and 3 percent dietary fish oil group, in terms of daily feed intake, total feed intake, weight gain, and average daily gain (P0.05). In contrast, there were no significant difference among groups on slaughter weight, hot carcass, chilled carcass, and carcass length. However, the carcass backfat thickness of control group was significantly lower than that of the 1 percent and 3 percent dietary fish oil group (2.02, 2.60, 2.47 cm respectively). Similarly lean meat percentage (61.54, 59.93 and 59.96 percent, respectively) and loin eye area were the highest in the control group (50.51 square cm).
