Abstract. Experimental material consisted of 20 piglets from litters of 2 sows of wbp x pbz breed, crossed with the Pietrain x Duroc hybrid breed boar. The piglets were divided into two experimental groups of 10 animals. The experiment lasted 84 days, during which experimental group I received the feed in the form of a mash and group II in a pelleted form adapted to each of the rearing period. Analyzing ADFI rate between 5 and 28 days, a low, statistically significant (P ≤ 0.01) daily intake of feed was noticeable and amounted to 54.3 g for MS − 1 mixed feed and 63.6 for MG − 1 mixed feed. Daily gains were also statistically significant (P ≤ 0.05), favoring mash diet. Between days 29 and 50 no significant differences were observed in any of the tested parameters but the results speak in favor of pelleted mixed feed. A significant difference (P ≤ 0.05) was noted in average daily feed intake in the MS − 3 ration between days 51 and 84, compared to the MG − 3 mix, while the value of ADG did not show significant differences. Analyzing the whole testing period, i.e. from day 1 to 84 days after weaning, there was no significant difference in daily gains between mash and pelleted diets, feed consumption or final body weight.
