This study was conducted to evaluate effects of dietary nutrient levels on growth performance, blood urea nitrogen, and meat quality in finishing pigs. A total of ninety six pigs ($Landrace{\times}Yorkshire{\times}Duroc$) were used in this 66 day study. Dietary treatments included 1) T1 (ME 3,441 kcal/kg, CP 16.30%, Lysine 0.93%), 2) T2 (ME 3,433 kcal/kg, CP 17.00%, Lysine 1.00% and 3) T3 (ME 3,449 kcal/kg, CP 17.00%, Lysine 1.00%). During the overall period, there were no significant differences in ADG (average daily gain), ADFI (average daily feed intake), gain/feed ratio or BUN (blood urea nitrogen) among the treatments (p>0.05). The $b^*$ value of M. longissimus dorsi muscle color significantly increased (p<0.05) with T3 treatment compared to T2 treatment. However, there were no differences in the $L^*\;and\;a^*$ values, pH, M. logissimus dorsi area, drip loss, cooking loss, TBARS and WHC (water holding capacity) for pigs fed the various treatments (p>0.05). The total feed cost per kg of weight gain was not significantly different among the various dietary treatments (p>0.05). In conclusion, these results show no effects of dietary nutrient levels on growth performance and meat quality in finishing pigs, and also suggest that a high nutrient density diet may not be a beneficial feeding strategy for finishing pigs in terms of cost.
