Grazing Studies at Antelope Range A Progress Report 1964-69

Long term grazing management studies must cover both wet and dry phases of the climatic cycle in order to provide reliable estimates of the effects of various grazing management practices on livestock production and on the range resource. Intensity of grazing studies with sheep have been conducted at the Antelope Range since 1950. A progress report of this work was published by Gartner, Lewis and Trevillyan (1965). The first phase of this study was concluded in 1962

Effect of Flushing and Gonadotropin on Ovulation Rate of Yearling Ewes on Range

Improvement of the reproduction rate of range ewes is of the utmost importance to the range sheep producer. Good grazing management and proper supplementation have been shown to be important. Flushing range ewes has given conflicting results. Gonadotrophic hormones have been used to increase ovulation rates but have been less successful with yearlings than with older ewes

The ecology and management of bluebunch wheatgrass (Agropyron spicatum) : a review

Agropyron spicatum, considered one of the most important native bunchgrasses in British Columbia, western Montana, the Columbia Basin and the area between the Cascades and Sierras and the Rockies, dominated millions of acres of pristine semiarid grass and sagebrush sites. It produced more herbage than all other associated species in these regions. A considerable amount of research has been done with this species since J. E. Weaver's work on roots in 1915. This review summarizes information from more than 300 articles relating to taxonomy, morphology, forage quality, ecology, physiology, and management of A. spicatum. It has been arranged so persons can easily locate articles relating A. spicatum to these various subject areas.Published July 1994.

Characterization of Testing Locations for Developing Cool-Season Grass Species

The identification of best testing locations facilitates the allocation of resources in a breeding program, allowing emphasis to be placed at the sites best suited for identifying superior plant materials for the target environment. The objective of this study was the identification of best locations for the evaluation and testing of cool-season grass species within the Northern Great Plains and Intermountain regions of the USA. This study also sought to subdivide the locations into meaningful environmental groupings based on similar entry performance. The study characterized initial stand frequency and forage production (over a 3-yr period) of crested wheatgrass [Agropyron cristatum (L.) Gaertn.; A. desertorum (Fisch. ex Link) Schultes; A. fragile (Roth) Candargy], intermediate wheatgrass [Thinopyrum intermedium (Host) Barkworth & D.R. Dewey], and smooth bromegrass (Bromus inermis Leyss.) at six locations within these regions. Results suggested the existence of best testing locations and environmental groupings for each of the species. For example, the Ithaca, NE, location was consistently a good location for testing forage production. Although there were some consistencies, generally, the best testing locations and environmental groupings were species and trait specific. Thus, the targeted use of locations appeared to be most useful on an individual species basis, rather than considered across the cool-season grass species
