There is surplus protein and energy that cannot be digested in diet than required. This study investigated the effect of balancing the concentration of nutrients in pigs’ diets aiming at reducing environmental wastage. Eighteen weaned pigs were randomly distributed into three treatments: 22%CP and 3200ME Kcal/kg; 20%CP and 3300ME Kcal/kg; 18%CPand 3400ME Kcal/kg. Each treatment had three replicates and two pigs per replicate. Data were collected on growth parameters, blood profile and nutrient digestibility. Pigs fed treatment 1 had significantly higher (p<0.05) average feed intake and average final weight. Significant (p<0.05) higher values were observed in cholesterol level and high density lipoprotein level in pigs fed treatment 3. Pigs fed treatment 3 had significantly (p<0.05) higher levels of triglyceride and total protein (252.87mg/dL and 7.44mg/dL) compared to those fed with treatment 1 (210.34mg/dL and 5.78mg/dL) respectively. However, low density lipoprotein level increased significantly (p<0.05) in pigs fed treatment 1 (11.13mg/dL) compared to treatment 3 (3.14mg/dL). Digestion of crude protein was significantly (p<0.05) higher (88.71%) in pigs fed treatment 3 compared with treatment 1 (85.12%). It can be concluded that reducing crude protein level to18% and increasing metabolizable energy level to 3400 Kcal/kg in feed would lead to improved nutrients utilization and absorption in pigs.
