Some Morphological And Chemical Responses Of Blackbrush (Coleogyne Ramosissima) To Goat Browsing: Influences On Dietary Blackbrush Selection By Goats And Cattle, Frederick D. Provenza
Some Morphological And Chemical Responses Of Blackbrush (Coleogyne Ramosissima) To Goat Browsing: Influences On Dietary Blackbrush Selection By Goats And Cattle, Frederick D. Provenza
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Domestic goats were used to modify the growth form of blackbrush, a spinescent shrub occurring in nearly monospecific stands on several million hectares of rangeland in the southwestern United States. The objective of this research was to evaluate goat browsing as a means of improving these rangelands for cattle. Winter goat browsing stimulated spring twig growth from basal and axillary buds which resulted in increased production.
Twig production by heavily browsed plants (>95 percent removal of current season's twigs) was a function of precipitation, soil depth, branch location on the plant, and period of rest after browsing. As precipitation …
Economic Analysis Of Long-Term Management Strategies For Two Sizes Of Utah Cattle Ranches, Roger E. Banner
Economic Analysis Of Long-Term Management Strategies For Two Sizes Of Utah Cattle Ranches, Roger E. Banner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Utah cattle ranchers realize relatively little profit from ranch ownership and management. This study represents an attempt to identify ranch management strategies that produce more profit over time than do conventional strategies.
To identify optimum management strategies for the long term, analyses of ranches under both normal and adverse ranch operation conditions using the COPLAN linear programming model were made for strategy comparison. To depict these ranch business environmental conditions, production levels were estimated from available biological data and price levels were estimated by indexing 1977 ranch product prices (the most current budget data available for Utah). The variability of …
G81-581 Cross Fences For Pastures Under Center Pivot Irrigation, James T. Nichols
G81-581 Cross Fences For Pastures Under Center Pivot Irrigation, James T. Nichols
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide discusses different types of fences for center pivot irrigated pastures.
Irrigated pastures produce more forage and maintain stands longer under a "graze-rest" system of use. When grazing is practiced season-long, cross fences are necessary to control 1) when and for how long grazing is permitted on a particular pasture, and 2) the degree of desired use. These controls are not possible without cross fences, and sound grazing management becomes difficult.
G81-574 Reproductive Diseases In Cattle, Duane Rice
G81-574 Reproductive Diseases In Cattle, Duane Rice
University of Nebraska-Lincoln Extension: Historical Materials
The reproductive diseases mentioned in this NebGuide comprise some of the more common problems confronting the cattle industry today.
Although many advances have been made in controlling reproductive diseases in cattle, serious losses are still common. These losses can be reduced by recognizing the diseases and following the proper management recommendations that are available today. Nearly 50 percent of reproductive failure in cattle is due to infectious diseases, and there are vaccines available that can prevent some of these. Management recommendations may include: 1) vaccines, 2) general sanitation, 3) artificial insemination (AI) or, if a problem is already present, 4) …
