Brucellosis In The Greater Yellowstone Area: Disease Management At The Wildlife–Livestock Interface, Brant A. Schumaker, Dannelle E. Peck, Mandy E. Kauffman Jan 2012

Brucellosis In The Greater Yellowstone Area: Disease Management At The Wildlife–Livestock Interface, Brant A. Schumaker, Dannelle E. Peck, Mandy E. Kauffman

Human–Wildlife Interactions

Elk (Cervus elaphus) and bison (Bison bison) of the Greater Yellowstone area are the last known reservoir of bovine brucellosis (Brucella abortus) in the United States. Domestic cattle occasionally contract the disease while grazing in areas where infected wild ungulates have aborted their fetuses or have given birth. Cases of brucellosis in cattle trigger costly quarantine, testing, and culling procedures. Government agencies and stakeholders, therefore, allocate valuable resources to prevent wildlife-to-cattle transmission. Scientific uncertainty about the biology, epidemiology, and economics of brucellosis makes it difficult to determine the length to which society should go to control it or the combination …

The Effect Of European Starlings And Ambient Air Temperature On Salmonella Enterica Contamination Within Cattle Feed Bunks, James C. Carlson, Jeremy W. Ellis, Shelagh K. Tupper, Alan B. Franklin, George M. Linz Jan 2012

The Effect Of European Starlings And Ambient Air Temperature On Salmonella Enterica Contamination Within Cattle Feed Bunks, James C. Carlson, Jeremy W. Ellis, Shelagh K. Tupper, Alan B. Franklin, George M. Linz

Human–Wildlife Interactions

European starlings (Sturnus vulgaris) are a known risk factor for the occurrence of microorganisms that are pathogenic to cattle and humans in concentrated animal feeding operations (CAFOs). Starling use of CAFOs is known to vary in response to weather; starling control operations on CAFOs often are timed to coincide with favorable environmental conditions to maximize take. The totality of this information suggests that disease risks in CAFOs associated with starlings may be influenced by environmental factors, such as temperature. In this study, we assessed the risk of Salmonella enterica contamination of cattle feed by modeling the interaction between …

Feed Depredation By European Starlings In A Kansas Feedlot, Brandon E. Depenbusch, James S. Drouillard, Charles D. Lee Jan 2011

Feed Depredation By European Starlings In A Kansas Feedlot, Brandon E. Depenbusch, James S. Drouillard, Charles D. Lee

Human–Wildlife Interactions

Confinement cattle-feeding operations have been associated with large populations of starlings (Sturnus vulgaris) during the winter months. Starlings can eat nearly 1 kg each of feed per month (Besser et al. 1968). In the first of our 2 studies, we evaluated feed selection and feed depredation by starlings using 5 concentrate-based cattle finishing diets. Four diets evaluated were in traditional meal-type form, and 1 diet was an extruded pellet. We placed rations into a section of the feed trough that we made accessible to starlings but not to cattle. Of the original 13.6 kg of steam-flaked corn and …

Habitat Correlates Of Jaguar Kill-Sites Of Cattle In Northeastern Sonora, Mexico, Octavio C. Rosas-Rosas, Louis C. Bender, Raul Valdez Jan 2010

Habitat Correlates Of Jaguar Kill-Sites Of Cattle In Northeastern Sonora, Mexico, Octavio C. Rosas-Rosas, Louis C. Bender, Raul Valdez

Human–Wildlife Interactions

Predation on cattle by the endangered jaguar (Panthera onca) can be a serious ecological and economic conflict. We investigated habitat characteristics of kill sites of cattle in Sonora, Mexico, from 1999 to 2004 to see whether habitat management or cattle distribution could be used as effective nonlethal methods to limit predation. Kill-sites were positively associated with oak, semitropical thornscrub, and xeric thornscrub vegetation types, whereas they were negatively associated with upland mesquite. Sites of cattle kills were also positively associated with proximity to permanent water sources and roads. A model including these relationships fi t kill locations well …

Deer Guards And Bump Gates For Excluding White-Tailed Deer From Fenced Resources, Kurt C. Vercauteren, Nathan W. Seward, Michael J. Lavelle, Justin W. Fischer, Gregory E. Phillips Jan 2009

Deer Guards And Bump Gates For Excluding White-Tailed Deer From Fenced Resources, Kurt C. Vercauteren, Nathan W. Seward, Michael J. Lavelle, Justin W. Fischer, Gregory E. Phillips

Human–Wildlife Interactions

White-tailed deer (Odocoileus virginianus) causing damage is a reoccurring theme in the realm of wildlife damage management, especially regarding human safety, disease transmission, and agricultural losses. Fences often are the only reliable long-term nonlethal means of controlling deer damage. The efficacy of fences, however, relies on their weakest link: human-operated gates. Although not overly time-consuming, the act of closing a gate appears to be a burden to individuals, resulting in open-access to an otherwise protected resource. We examined the efficacy of 2 alternatives to traditional gates to evaluate their potential to be used for excluding or containing deer. …

A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark Jan 2007

A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark

Human–Wildlife Interactions

Cattle are the main reservoir for human infection by pathogenic Escherichia coli and Salmonella enterica. To prevent entry of these foodborne pathogens into the human food chain, management factors at the farm level must be identified and controlled. External sources of contamination, such as birds, should be considered as potential sources of transmission over long distances. In this review, we focus on the epidemiology of infection by E. coli and S. enterica and the consequences of birds acting as disseminators of these pathogens at dairy farms in terms of cattle health and the subsequent effects on human health.

Herd Efficiency And Profitability, Jesse Russell, D. R. Zobell Apr 2004

Herd Efficiency And Profitability, Jesse Russell, D. R. Zobell

All Current Publications

Raising beef cattle can be very rewarding. First, if you like raising cattle, maintaining your tie to the land, and seeing the product of your labors, it can truly be satisfying to see young calves in the spring, watch them grow and progress. Second, here can also be a financial reward when the calves are weaned and sold. However, the satisfaction of these two aspects may all depend on your herd’s efficiency and profitability.

Fall Calving In The Intermountain West, Dale R. Zobell, Craig Burrell, Darrell Rothlisberger, Eleanor Jenson Aug 2003

Fall Calving In The Intermountain West, Dale R. Zobell, Craig Burrell, Darrell Rothlisberger, Eleanor Jenson

All Current Publications

Fall calving has been practiced by beef producers for many years, although in small numbers relative to spring calving. The spring calf crop has been a traditional event for most beef producers and probably will continue to be. There are distinct advantages, however, to fall calving which producers could take advantage of. The potential for higher conception and weaning rates, price premiums and the elimination of calf scours are among the reasons some beef producers have switched from spring calving their herd to fall calving.

Video Ordering Information For Realizing The Impact Of Injection Site Lesions, Clell Bagley Jun 2001

Video Ordering Information For Realizing The Impact Of Injection Site Lesions, Clell Bagley

All Current Publications

Injection of almost any drug or solution into the muscles of a food animal will result in scar tissue formation and some residual lesion in those muscle tissues. These lesions are very displeasing to consumers if found in meat products. Their presence also contributes to loss of tenderness for much of the remainder of the cut of meat. If found during processing, the lesions can be trimmed out but this still results in trim loss and increased labor costs for the processor.

Proper Use Of Ammoniated Low-Quality Forages For The Wintering Of Spring-Calving Beef Cow Herds In The Intermountain West, D. R. Zobell Jan 2000

Proper Use Of Ammoniated Low-Quality Forages For The Wintering Of Spring-Calving Beef Cow Herds In The Intermountain West, D. R. Zobell

All Current Publications

Low‐quality forages (LQF) such as cereal straws or post‐ripe hays are often used as economical feed sources for the wintering of beef cow herds. The ammoniation of such forages increases the digestibility and crude protein (CP) enough so that these forages can be used as the basis of beef cow diets, even during late gestation and early lactation if supplemented properly.
