Greater Sage-Grouse Response To Sagebrush Reduction Treatments In Rich County, Utah, Roger Blair Stringham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Management of greater sage-grouse (Centrocercus urophasianus) in the west has changed over the last several decades in response to environmental and anthropogenic causes. Many land and wildlife management agencies have begun manipulating sagebrush with herbicides, machinery, and fire. The intent of these manipulations (treatments) is to reduce sagebrush canopy cover and increase the density of grass and forb species, thus providing higher quality sage-grouse brood-rearing habitat. However, monitoring of sage-grouse response to such manipulations has often been lacking or non-existent. The objective of our study was to determine the response of sage-grouse to sagebrush reduction treatments that have …

Treatment Of Low Quality Forages By Hydrogen Peroxide And(Or) Anhydrous Ammonia And Their Utilization In Ruminant Nutrition, Mohammed Diouri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three experiments were conducted to evaluate low quality forages treatment by anhydrous ammonia (NH₃) and(or) hydrogen peroxide (H₂O₂).

In experiment I, a control and three treatments of barley straw were compared: NH₃, NH₃ after rehydration of the straw with water (NH₃+H₂O), and NH₃ after rehydration with a H₂O₂ solution (NH₃+H₂O₂). Forages were fed, with a supplement, at two levels of intake (ad libitum and 75% of ad lib.). Treatments were administered in a split-plot in a Latin …
