Three experiments were conducted to compare high (20.6%) or low (4.0%) erucic acid rapeseed oils with soybean oil when the oils were fed at a level of 15% of the diet for pigs from 25 to 90 kg liveweight. The low erucic acid rapeseed oil originated from Brassica campestris cv. Span. A fourth diet containing no supplemental oil served as a control. In one experiment, 48 crossbred pigs were fed ad libitum in groups of three pigs replicated four times. In a second experiment, 48 pigs were individually fed at a level of 80% of the daily caloric intake of the pigs in the first experiment. In a third experiment, 16 pigs in four groups were allowed continuous free-choice access to the four diets. Serial slaughter and digestibility data were obtained. The incorporation of high or low erucic acid rapeseed oil in the diets did not reduce pig performance when such diets were fed either ad libitum or at a restricted level. When given a choice of feed, pigs selected less of the high erucic acid rapeseed oil diet. When not given a choice of feed, pigs consumed as much of a high erucic acid rapeseed oil diet as they did of the other diets. Digestibility coefficients for energy, nitrogen and lipids were not significantly different for any of the three oil-containing diets. Histological examination of the heart, liver and spleen revealed no marked differences due to feeding any of the oil-based diets.

Male Sprague-Dawley rats were fed diets containing 20% (w/w) soya-bean oil, high-erucic acid rapeseed oil or low-erucic acid rapeseed oil for 0, 12 or 23 days. The type of fat present in the diet had no effect on the total phospholipid content of heart mitochondria (micrograms/mg of protein) but did influence the phospholipid class distribution. Rats fed high-erucic acid rapeseed oil for 12 or 23 days had significantly higher mitochondrial phosphatidylcholine content than rats fed soya-bean oil. Low-erucic acid rapeseed oil resulted in elevation of cardiac mitochondrial cardiolipin content after dietary treatment for 12 days. The results demonstrate in vivo that diet is a significant determinant of the phospholipid class content of subcellular membranes.

Maximal Expression

Enzymic activities and gene expression of oleoylCoA elongase were studied during seed development using two different rapeseed cultivars, high-erucic-acid rapeseed (HEAR) and low-erucic-acid rapeseed (LEAR). The overall elongase activities were maximal in HEAR between the fourth and eighth weeks after pollination (WAP) and absent in LEAR. The 3-ketoacyl-CoA synthase (condensing enzyme, CE) mRNA levels and the developmental profiles in the two cultivars were different since maximal expression levels were detected in HEAR and LEAR at WAP 4 and WAP 6, respectively. Anti-CE antibodies revealed two proteins of 60 and 67 kDa in both cultivars and an additional reacting protein of 57 kDa in HEAR.
