Nutritive Values Of Russian Wildrye, Crested Wheatgrass, And Intermediate Wheatgrass Grazed By Cattle On Utah Foothill Ranges, George W. Mitchell
Nutritive Values Of Russian Wildrye, Crested Wheatgrass, And Intermediate Wheatgrass Grazed By Cattle On Utah Foothill Ranges, George W. Mitchell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A comparative index to digestible nutrients was established for Russian wildrye, crested wheatgrass, and intermediate wheatgrass seeded on foothill areas of Utah. The nutritive values of these grasses were compared by the lignin ratio method, the chlorophyllan ratio method, and the in vivo rumen bag process.
Average digestion coefficients computed by the lignin ratio method for dry matter, ether extract, cellulose, and gross energy were highest for intermediate wheatgrass. Protein was more digestible for Russian wildrye. Digestible energy was adequate in all species to meet requirements for late lactation.
Results from the chlorophyllan ratio method were excessively high and were …

Determining Market Areas For Livestock Grazing, Robert G. Williams
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Differentials between rancher costs of operating on private and public range were studied in an attempt to define market areas for livestock grazing in western United States.
The problem of defining market areas is basically a problem of grouping differentials between rancher costs of grazing on private leased range and National Forests that are reasonably homogeneous and statistically testing differences among means of the different groups.
Several methods were used to group forests with reasonably uniform differentials into market areas for cattle. A grouping of forests which have the same average grazing fee does not, however, yield market areas which …
