Extract

In designing feeding regimens for sows much attention should be paid to the effects on piglet performance and piglet mortality, as these traits are of great economic significance. Clearly, piglets may be influenced by sow feeding regimen in several ways. For example, sows offered food ad libitum may be calmer and hence step upon or overlay fewer piglets than sows restrictedly given food. A gestation diet with a low protein content and protein of vegetable origin may reduce the frequency of agalactia (Ringarp, 1960; Göransson, 1989) and thereby enhance piglet survival.

In a sow feeding experiment performed at the Swedish University of Agricultural Sciences, the Swedish feeding standards (Simonsson, 1988) were compared with offering food ad libitum in lactation and a simplified gestation diet. The main objective was to study effects on sow weight and backfat changes and reproductive traits, but effects on piglet mortality were also studied.

The experiment was performed at the pig research station of the Swedish University of Agricultural Sciences from 1986 to 1990. The following treatments were applied.
