Abstract

For the purpose of comparing the effects of rapeseed oil and soybean oil on the weight increment and thriving of young pigs two experiments were performed. The first experiment was made with 12 and the second with 10 pigs divided into two groups, groups R receiving rapeseed oil and groups S receiving soybean oil in their food. The share of added oil in the net energy content of the food mixture was 34.5 %. Each experiment was divided into a period of restricted feeding and a period of ad libitum feeding. During the restricted feeding no marked differences between the two groups could be noticed, but during the ad libitum feeding in the second experiment the animals of group S showed a better appetite and a more rapid weight development than their mates in group R. In addition, there was a difference in the consumption of drinking water between the two groups in each experiment. The animals of groups R consumed more water than their mates. In the investigation of the bodies after slaughtering no differences were noticeable between the groups.
