| Summary: | Present study was conducted to evaluate the effects of supplementation of pig specific mineral mixture on growth performance, nutrient digestibility and production economics. Fattening pigs (12) of 4 month-old, with an average body weight of 47.12±0.13 kg were subjected to 3 different isocaloric and isonitrogenous rations having pig specific mineral mixture at the rate of 0, 1.5 and 2.0%, respectively. Growth performance and digestibility coefficient of nutrients were assessed at 45 days and 90 days of experiment. Results showed that during the entire experimental periods pig specific mineral mixture supplementation @ 1.5% significantly improved body weight gain, FCR of pigs over control but further no significant improvement was observed with 2% supplementation rate. However, in comparison to control, only at 90th days of experiment digestibility coefficient of DM, CP and EE was significantly higher in pigs supplemented with 1.5% mineral mixture with no significant difference with 2% supplemented group. Moreover, calcium retention at both 45th and 90th day and phosphorus retention only at 90th days of experiment was significantly better in pigs supplemented with 1.5% mineral mixture with no further improvement with 2% supplementation. Margin of receipts per pig over feeding cost in 1.5% supplemented group was highest and was Rs. 833.60 higher than control. It was concluded that dietary inclusion of pig specific mineral mixture @ 1.5% is sufficient to improve the growth performance and nutrient digestibility with highest economic return from fattener pigs.
