During the whole experiment, the body weight of sows did not significantly differ among groups (Table 1). The average body weight of sows at mating was similar in all groups and amounted to 206–225 kg, and at the end of reproductive cycle, body weight of all sows was higher by 19.1–22.3 kg, in comparison to the body weight at the beginning of cycle. During lactation sows lost weight: 9.9 kg (group II) and 12.6 kg (group IV). There was no significant difference among groups in feed intake during the whole reproductive cycle (Table 1).
Body weight gains and feed utilisation of piglets were similar in all groups (Table 2). In the experiment, 265 piglets were born and their average body weight at 1st d of age was 1.46 kg and at weaning 7.21 kg. During the nursing period (1-28 d of age), the average daily weight gains amounted to 214 g and after weaning (28-84 d of age) – 346 g.
