Excerpt from The Feeding of Dairy Cattle
The art and science of feeding dairy cattle has ever been changing, and during the last two decades greater improve ments have been brought about in this branch of agriculture, by practical feeders and investigators, than ever before. ... The importance of the dairy cow as an economic factor is now recognized. This is primarily due to the fact that, with little waste of energy, she converts the roughages and other feeds grown on the farm into products suitable for human consumption.
In making this presentation of the feeding problem the aim has been to render the work broad enough to be of aid to the student. For this purpose the earlier sections contain a brief résumé of material which belongs to the field of nutri tion rather than to that of feeding. It is hoped that this will render it possible for the student to link up his work on feeding dairy cattle with the training he has previously received in nutrition. At the same time it is hoped that the man interested in feeding, but with little foundation in nutrition, may obtain some information of value from the earlier part of the work. To put it brie¿y, the main object in view has been to review, in a non-technical manner, the main principles on which the feeding of dairy cattle is founded and then discuss the problems of practical feeding.
