Daily administration of 40—60 kg rape for 9 weeks to 8 cows produced no changes in the red blood picture. On the other hand a reduction of the myeloid: erythroid ratio and the maturity ratio of the erythroid cells of the bone marrow was found. This is interpreted as a sign of increased erythropoiesis. The Brassica-induced anaemia found in other investigations is assumed on several grounds to be haemolytic. The present study confirms this assumption, the increased breakdown of erythrocytes being entirely compensated by an increased erythropoiesis. The difference between the present and earlier reports, in which anaemia was found after a shorter time of feeding on roughly the same quantities of rape, is discussed, one possible explanation being that differences exist in rhodanid content between Brassica species.
给8头奶牛每日投喂40 - 60千克油菜，持续9周，红细胞指标未出现变化。另一方面，发现骨髓中髓系与红系比例以及红系细胞成熟比例降低。这被解释为红细胞生成增加的迹象。基于多种原因，其他研究中发现的十字花科植物诱导的贫血被认为是溶血性的。本研究证实了这一假设，红细胞分解增加完全由红细胞生成增加所补偿。文中讨论了本研究与早期报告之间的差异，早期报告中在投喂大致相同数量油菜较短时间后发现了贫血，一种可能的解释是不同十字花科植物物种中的硫氰酸盐含量存在差异。
