The effect of physical treatment of prestarters on production and nutritional characteristics was studied in one on-farm comparative feeding trial with 318 piglets and in one metabolism trial with 12 piglets. A prestarter of uniform standardized formulation was fed: untreated ingredients were used in control group (N), grains and protein feeds were extruded in group E and a loose mixture was used, and the prestarter in group G was treated in the same way as in group E, but it was in granular from. The best results were obtained in group G. Average daily weight gain after weaning was higher by 46 % in comparison with the control, total weight gain was higher by 29 %. The results of metabolism trial show significantly positive effects of physical treatment (extrusion, granulation) on protein utilization and deposition, especially at 36-40 days of age, when protein deposition in piglets of group G was higher by 45 % in comparison with the control (N). Significant differences were also indicated by comparison of groups N and E (by 27 %).
