The effect of the use of vitamin-mineral pre-mixtures (premixes) imported and domestic (Serbian) origin were investigated in nutrition of fatteners. Research was performed on private farm Fencaroš in Platičevo near Šabac (Serbia). Obtained results showed that: Pigs fed mixtures containing domestic pre-mix realized better gain by 7.6% and better feed consumption by 7.4%. No significant difference in feed conversion between compared groups of animals in the trial was recorded. Domestic premix in mixtures reduced the cost of mixtures by 4.1% and reduced the cost of gain in fatteners by 4.5% compared to nutrition with diets containing imported premixes. Pigs fed domestic pre-mix, realized by 2.0% higher dressing percentage determined on slaughter line compared to animals fed imported pre-mix in the mixture, although the meatiness was the same. In general, obtained results showed that the utilization of both types of compared premixes can be recommended, but it is more economically efficient to use domestic premixes in nutrition of fattening pigs.
