After a review of the literature the report of a trial with 30 dairy cows is presented. The cows were divided into 3 groups of 10; 1 group functioned as control (A), 1 had free access to marrow-stem kale (B), and the animals of the 3rd received 10 kg marrow-stem kale daily (C). The trial period lasted about 6 weeks. Blood samples from all animals were taken before the trial began, twice in the course of the experiment, and 3 weeks after its termination. Estimations were made for haemoglobin, haematocrit, the erythrocyte in vitro uptake of I-triiodothyronine, total protein and protein fractions, serum calcium, inorganic phosphorus and magnesium, as well as for the serum activity of glutamic-oxalacetic acid transaminase (GOT) and ornithine-carbamyl-transferase (OCT). During the trial period differences between groups A and B existed only in haemoglobin and haematocrit, the experimental animals having significantly lower values. The erythrocyte in vitro uptake of triiodothyronine demonstrated a tendency towards lower values in both experimental groups. Other blood values varied between different samples but not between groups. Special mention is made of the total protein value which was substantially lower for the 2nd sample than for the others. This may have been associated with the change from pasture to stall feeding which occurred at the beginning of the trial.
在对文献进行综述之后，本文呈现了一项针对30头奶牛的试验报告。这些奶牛被分为3组，每组10头；1组作为对照组（A组），1组可自由采食羽衣甘蓝（B组），第3组的动物每天接受10千克羽衣甘蓝（C组）。试验期持续约6周。在试验开始前、试验过程中两次以及试验结束后3周采集所有动物的血样。对血红蛋白、血细胞比容、红细胞对I-三碘甲状腺原氨酸的体外摄取、总蛋白和蛋白组分、血清钙、无机磷和镁进行了测定，还测定了谷草转氨酶（GOT）和鸟氨酸氨甲酰转移酶（OCT）的血清活性。在试验期间，A组和B组之间仅在血红蛋白和血细胞比容方面存在差异，实验动物的值显著较低。两组实验组的红细胞对三碘甲状腺原氨酸的体外摄取均呈现出较低值的趋势。其他血液值在不同样本之间有所变化，但组间无差异。特别值得一提的是，第二个样本的总蛋白值明显低于其他样本。这可能与试验开始时从放牧饲养改为圈养饲养有关。
