Over 100 years of county agricultural practices:

UC Cooperative Extension Archive continues to grow

The University of California Cooperative Extension (UCCE) dates back to 1914, when farm advisors began to work with local farmers in every county of the state to help shape agricultural practices. For over a hundred years, county offices throughout California have documented activities including agricultural trials, animal husbandry, water management, fire management, the development of integrated pest management, rural food and nutrition programs, and youth development programs, among others.
In the fall of 2016, the UC Merced Library, under a memorandum of understanding with the University of California’s Division of Agriculture and Natural Resources, began archiving and providing digital access to historical materials held in county Cooperative Extension offices. A Major Initiatives grant from the National Historical Publications & Records Commission has supported the expansion of this work. 

These documents provide a fascinating glimpse into efforts to cut high agricultural expenses, such as providing horses with essential nutrients at a lower cost. While alfalfa may be the type of hay preferred by horses, an item found in the Humboldt County UCCE Records collection notes the high cost of hay and suggests alternative sources of food and supplements that might still provide the energy, protein, minerals, vitamins, and fiber that a horse requires. A publication from the 1970s lists pellet foods, corn cobs, citrus pulp, almond husks as viable options... but also includes an item that we’re convinced is neither palatable nor tasty: cardboard.

What essential nutrients could a sturdy, corrugated, brown paper box possibly provide? Find out more in this document called “What can we feed horses?” (Note that diet and nutrition is an ever evolving science, and the recommendations in this document from 1979 may not align with contemporary horse care and ethical practices.)
"What can we feed horses?" 1979, October.
