完全精炼的高菜籽油（普通菜籽油，B。campestris）和低芥酸（Span oil，B. campestris;商业氢化司盘油和西风油，B. napus）和大豆油以饮食中15重量%的水平喂给雄性和雌性Sprague-Dawley大鼠。在第一个实验中，每个处理组5只雄性和5只雌性大鼠单独圈养，而在第二个实验中，每个处理组5只雄性或5只雌性大鼠以5只为一组圈养。实验1中，体重增加不受饮食处理的影响。然而，在实验2中，与食用大豆油的组相比，食用含有普通菜籽油或斯潘油的饮食的组显示出显着（P小于0.05）较低的体重增量，但与食用氢化斯潘油或Zephyr油的组相比则不然。大鼠心脏组织中发现局灶性病变，但肝脏和脾脏组织中未发现。病变的发生率是相似的所有口粮处理。雄性大鼠心脏病变的发生率显著高于雌性大鼠（P <0.01）。
Fully refined rapessed oils of high (regular rapeseed oil, B. campestris) and low erucic acid content (Span oil, B. campestris; commercially hydrogenated Span oil and Zephyr oil, B. napus) and soybean oil were fed to male and female Sprague-Dawley rats at a level of 15% by weight in the diet. In the first experiment, 5 male and 5 female rats per treatment were housed individually, whereas in the second experiment 5 male or 5 female rats per treatment were housed in groups of five. Body weight gain was not influenced by the dietary treatments in experiment 1. However, in experiment 2 the groups fed the diets containing regular rapeseed oil or Span oil showed significantly (P less than 0.05) lower body weight gains when compared to soybean oil fed groups but not when compared to the hydrogenated Span or Zephyr oil fed groups. Focal lesions were found in cardiac tissue of the rats, but not in liver and spleen tissue. The incidence of lesions was similar on all ration treatments. A significantly (P LESS THAN 0.01) higher incidence of cardiac lesions was found in male rats than in female rats.
