An experiment was conducted using 30 replacement sows (distributed in 3 groups) with the aim to study the effects of three nutrition levels during pregnancy. The experiment began with mating the sows and it lasted till the weaning of pigs at 35 days of age. During the pregnancy each sow from the group 1 (control) received 2.2 kg/day until the day 80 and 2.7 kg/day from the day 81 to farrowing, those from the group 2, 1.9 kg/day per sow for the entire period, and the group 3, 3.6 kg/day per sow received compound feed containing 13 % of crude protein. During lactation all sows had free access to compound feed containing 15.5 % crude protein. The nutrition level during pregnancy did not affect the number and weight of piglets in the litter at birth and weaning, but had direct effects on the gain of mothers during pregnancy and adverse effects on feed intake and gains of sows during lactations.
