Because of the specific structure of pigs' digestive tract, especially in baby pigs, animal feeds must be composed of highly concentrated digestible nutrients of high quality. The purpose of our investigation was to test the individual impact of added enzyme(s) (experimental group I), thermally processed ingredients (micronization) in feeding rations (experimental group III) as well as joint effect of enzymes and thermally processed feed for weanlings (experimental group II). The best results of feed conversion were obtained in experimental group II, 10 % lower than the results obtained in the control group. Daily weight gain and body weight were also recorded in different phases and the results were better in all three experimental groups than in the control group. Piglets from the second experimental group were characterised by the highest body weight and the highest daily weight gain, which was statistically significant in relation to experimental group I and the control group. As for the daily weight gain, positive results obtained in the third experimental group were statistically significant. Our investigations thus proved a positive joint effect of enzymes and micronization in feeding rations for piglets.
