Evaluation Of Drug-Resistant Enterobacteriaceae In Retail Poultry And Beef, Agnes Kilonzo-Nthenge, Emily Rotich, Samuel N. Nahashon

Agricultural and Environmental Sciences Faculty Research

There has been increasing concern on the emergence of multidrug-resistant foodborne pathogens from foods of animal origin, including poultry. The current study aimed to evaluate antibiotic-resistant Enterobacteriaceae from raw retail chicken/turkey parts (thigh, wings, breast, and ground) and beef meat (ground and chunks) in Middle Tennessee. Resistance of the collected Enterobacteriaceae to a panel of antibiotics was determined by the Kirby-Bauer disk diffusion test. Retail meats were also assayed for the presence of Salmonella spp. and Escherichia coli O157:H7. Two hundred thirty-seven samples representing 95.2% of the total of 249 samples tested were positive for Enterobacteriaceae. The level of contamination …

Certified Angus, Certified Patriot: Breeding, Bodies, And Pedigree Practices, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

The pedigree chart is a cornerstone technology for producing bodies and value in livestock pure breeding. It organizes a cluster of processes, technologies, and discourses gathered under the rubric “pedigree practices.” Angus breeders commonly use artificial insemination to import performance “genetics” into their herds, using the “expected progeny differences” predicted by massive pedigree databases that now also contain phenotype data reported by cattle growers. Discourses of biological inheritance, good breeding, and pedigrees arose in the eighteenth century, concomitant with a fascination with races, species, and other biological kinds. A case study from Angus cattle breeding illustrates pedigree practices and the …

Wetland Management Guidelines For Nebraska's Wildlife Management Areas, Ted Lagrange, Randy Stutheit

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Prior to Euro-American settlement, wetlands covered about 6% of the Nebraska landscape. Since settlement, the state’s wetlands have suffered serious decline. For example, approximately 90% of Rainwater Basin playa wetlands and 90% of the eastern saline wetlands have been destroyed or are highly degraded. Remaining wetlands are threatened by conversion to other uses (e.g. agriculture), invasive and aggressive vegetation, siltation, and lack of proper management. Only through sound management can the wetlands on our Wildlife Management Areas (WMA) be preserved for the citizens of Nebraska, as well as the native plants and wildlife dependent on them.

This section is directed …

Native Grassland Management Guidelines For Nebraska's Wildlife Management Areas, Gerry Steinauer, Kent Pfeiffer, Jarren Kuipers

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

This document is one of a four part series produced by the Nebraska Game and Parks Commission to provide direction to managers of Wildlife Management Areas (WMAs) in Nebraska. Other documents in the series cover management of woodlands, wetlands, and converted habitats.

Prior to EuroAmerican settlement grasslands covered 98% of the Nebraska landscape and supported the majority of the state’s biodiversity. Since settlement, Nebraska’s native grasslands have suffered serious decline. For example, approximately 98% of eastern Nebraska’s tallgrass prairie has been lost to development. In central and western Nebraska grassland losses have been less dramatic though still substantial. Remnant grasslands …

Native Forest And Woodland Management Guidelines For Nebraska's Wildlife Management Areas, Gerry Steinauer

This document is one in a four part series produced by the Nebraska Game and Parks Commission to provide direction to managers of Wildlife Management Areas (WMAs) in Nebraska. Other documents in the series cover management of grasslands, wetlands, and early successional habitats.

Prior to Euroamerican settlement wildfires, drought and competition with prairie grasses limited the presettlement distribution of trees in Nebraska to well-watered and somewhat fire protected river valleys and rocky escarpments. At that time, wooded habitats covered about 2 percent of the Nebraska landscape. Though limited in areal, these communities were diverse and supported important components of Nebraska’s …

The Effects Of Myd88 Inhibition On Bovine Lung Endothelial And Epithelial Cell Cytokine Expression, Cassandra Kay Hayne

Honors Program Theses

Bovine respiratory disease complex (BRDC) has major economical implications on the beef industry due to the severe health problems it produces in calves. Although several organisms are associated with it, Mannheimia haemolytica induces the severest amount of damage to the lungs. It has previously been demonstrated that lipopolysaccharide (LPS) produced by this bacterium causes significant permeability increases and cell apoptosis in bovine lung endothelial cells (BPMEC) but not bovine lung epithelial cells (TBPE). The purpose was to determine whether the main signaling pathway for cells that respond to LPS signaling, the Myeloid Differentiation 88 Pathway (MYD88), is present and functional …

Feeding Corn Milling Co-Products To Feedlot Cattle, 3rd Edition, Galen E. Erickson, Crystal D. Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Two primary types of milling processes currently exist, resulting in quite different feed products. These processing plants produce and market a variety of feed products, but in general, the dry milling process produces distillers grains plus solubles (DGS), and the wet milling process produces corn gluten feed (CGF). These feeds can be marketed as wet feeds, or they can be dried and marketed as either dry corn gluten feed (DCGF) or dry distillers grains (DDG) with or without solubles.

For the purposes of this report, wet corn gluten feed (WCGF), wet distillers grains plus solubles (WDGS), DCGF and dried …

Feeding Corn Milling Co-Products To Forage Fed Cattle, 1st Edition, Aaron Stalker, Rick Rasby, Galen E. Erickson, Crystal Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Beef calves from weaning until they enter feedlots, developing heifers, and beef cows are fed primarily forage diets. Especially in the winter, forages are low in protein and phosphorus and need to be supplemented. Corn milling co-products are excellent sources of both protein and phosphorus and fi t nicely into winter supplementation programs. Corn milling co-products are also an excellent source of energy and are particularly well suited to forage based diets.

Two primary types of milling processes currently exist, resulting in quite diff erent feed products. The dry milling process produces distillers grains plus solubles (DGS), and the …

Nlis National Livestock Identification System. Frequently Asked Questions, Department Of Agriculture, Western Australia

Animal production and livestock published reports

Replaces Miscellaneous Publication 29/2004

Which was issued in December 2004

Traceability is fast becoming the most prominent issue between global livestock trading partners. In the future, international markets will demand assurances that individual animals can be adequately traced for the whole of that animal's life , through multiple transactions, and ultimately to its property of birth.

In Australia, the National Livestock identification System or NLIS is the national system for lifetime traceability of livestock. NLIS will enable rapid trace back through all movements made by that animal to the property of that animal's birth in the event of a disease …

Re-Assessment Of Carrying Capacities In The Ashburton River Catchment, Alan L. Payne, A M E Van Vreeswyk, K A. Leighton

Agriculture reports

Potential carrying capacities for land systems in the catchment of the Ashburton River were first estimated in 1983 as a result of a rangeland survey of the area undertaken during 1976, 1977 and 1978. Potential carrying capacity (termed capability capacity in the 1988 report) is a suggested sustainable level of use assuming that all pastures are in good range condition, the entire station is adequately watered for the effective management of livestock and seasonal conditions are average.

The Ashburton Land Conservation District Committee had previously requested a re-assessment of carrying capacities for Ashburton stations following the widespread establishment of buffel …

Crop Performance And Soil Properties Of Sites Previously Used For Production Of Beef Cattle Manure Compost, Daniel Ginting, Bahman Eghball, Daniel T. Walters, Charles A. Francis, Terry J. Klopfenstein, Casey Wilson, Galen E. Erickson

Nebraska Beef Cattle Reports

This study was established on sites that had three or seven years of compost production history. Corn, wheat, barley, sorghum and alfalfa were planted in 2001. In the first year, wheat, barley and sorghum performed better than corn in the windrow areas while alfalfa did not even establish because of excessive salt in the soil. Soil electrical conductivity, K and Na in the 0-6 inch depth under windrows were high and caused soil crusting and poor germination and crop yields. Growing salt tolerant crops, such as barley, can rehabilitate sites used for composting and the process can be accelerated by …

New Beef Zone - The Potential For Beef And Cattle Industry Expansion In The Western Australian Wheatbelt, Alan Peggs, Andrew Quinn, Jason Kelly

Animal production and livestock published reports

Agriculture Western Australia (WA) recently completed a comprehensive analysis of the Western Australian beef and cattle industry entitled, “Rising Above the Herd” (Quin and Manners 1999). A key finding was the need to determine areas where store cattle could be produced competitively in the future. This was in the light of beef production in existing areas such as the South West and western South Coast being “squeezed” out by competition from alternative enterprises. This analysis has been prepared at the request of Agriculture WA to determine the potential for the Wheatbelt to produce store cattle competitively.

The study:
