Over 100 years, the Journal of Dairy Science has recorded incredible changes in the utilization of fat for dairy cattle. Fat has progressed from nothing more than a contaminant in some protein supplements to a valuable high-energy substitute for cereal grains, a valuable energy source in its own right, and a modifier of cellular metabolism that is under active investigation in the 21st century. Milestones in the use of fats for dairy cattle from 1917 to 2017 result from the combined efforts of noted scientists and industry personnel worldwide, with much of the research published in Journal of Dairy Science. We are humbled to have been asked to contribute to this historical collection of significant developments in fat research over the past 100 years. Our goal is not to detail all the work published as each development moved forward; rather, it is to point out when publication marked a significant change in thinking regarding use of fat supplements. This approach forced omission of critically important names and publications in many journals as ideas moved forward. However, we hope that a description of the major changes in fat feeding during the past 100 years will stimulate reflection on progress in fat research and encourage further perusal of details of significant events.
一百多年来，《乳业科学杂志》记录了奶牛脂肪利用的惊人变化。脂肪已经从一些蛋白质补充剂中的污染物发展成为谷物的有价值的高能替代品，本身就是一种有价值的能量来源，并且是细胞代谢的调节剂，在 21 世纪正在积极研究。1917 年至 2017 年，奶牛脂肪利用的里程碑是全球著名科学家和行业人员共同努力的结果，其中大部分研究成果发表在《乳业科学杂志》上。我们很荣幸被邀请为过去 100 年来脂肪研究的这一重要发展贡献力量。我们的目标不是详细描述每一项发展所发表的所有工作，而是指出当出版物标志着对脂肪补充剂使用的思维发生重大变化时。这种方法迫使我们忽略了许多期刊中许多重要的名字和出版物，因为这些想法在不断推进。然而，我们希望描述过去 100 年中脂肪喂养的主要变化，将激发人们对脂肪研究进展的思考，并鼓励进一步详细探讨重要事件。
