This experiment was conducted in Swine and Avian Research Program, Khumaltar, Lalitpur from 2017 to 2018 for the period of 180days. The objective of this study was to evaluate the different dietary protein level on effects of grower and starter piglet performance. Locally available feed ingredients were used for the feed formulation. Chemical analysis of all required feed ingredients was done and feed was formulated on the basis of nutrient requirement of pig. There were four treatment group (T1-22%, T2-20%, T3-18%, T4-16% for starter level and (T1-20%, T2- 18%, T3-16%, T4-14%) for grower level diet. Sixteen Landrace piglets (30 days old) were selected; four piglets were allocated in each treatment. Data was recorded for monthly average body weight, feed intake and feed conversion ratio. One finisher pig was slaughtered from each treatment for meat quality evaluation and sensory evaluation for different parameters was done by using formatted questionnaire. There was significant different in feed conversion ratio and body weight gain (p<0.05). FCR was better in treatment 3(2.78) compared to other treatment (2.90, 2.92, 2.95). During starter phase, the average body weight gain was higher in treatment 1(48.25kg) but grower phase’s showed contrast as body weight in treatment 3(63.50) was recorded to be highest. No significant difference in feed intake was recorded. Cumulative feed intake was 177 kg in all treatments group. Similarly, proximate analysis of carcass indicated 20% protein content in starter diet and 16% protein in finisher diet should be ideal for better body weight gain and feed conversion ratio.
