First Evidence Of Plague (Yersinia Pestis) In Nebraska Is Found In Panhandle Predators, Dallas Virchow, Wayne L. Kramer, Charles S. Brown, Scott E. Hygnstrom, Alan M. Barnes

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

In September, 1992, plague (Yersinia pestis) antibody was found in the blood of a coyote (Canis latrans) (1:128 titer) and a badger (Taxidea taxus) (1:2048 titer) taken near a suspect black-tailed prairie dog (Cynomys ludovicianus) town in Sioux County. However, a 1989-1991 survey of 96 coyotes taken from nine Nebraska Panhandle counties demonstrated no plague antibodies. Passive hemagglutination tests of Nobuto blood-sampling paper proved useful to quickly survey a predator population that is distributed across a broad geographic area.

Crossbreeding Systems And The Theory Behind Composite Breeds, James A, Gosey

Range Beef Cow Symposium

Crossbreeding serves the beef cattle industry as a tool to improve productivity through heterosis (hybrid vigor) and through complementarity (combining different breed strengths) to match genetic resources to various feed resources, climates, management levels and markets. Commercial cattlemen need to understand the principles of crossbreeding so they can adapt crossbreeding to their specific environment and needs. Seedstock breeders must be able to intelligently advise their commercial customers and know where their seedstock best fits into crossbreeding programs. Cattlemen today can be much more sophisticated in their approach to using crossbreeding. They realize many of the crossbreeding mistakes of the past …

Matching Cattle Nutrient Requirements To A Ranch’S Forage Resource, Or “Why We Calve Late”, Gregg Simonds

Range Beef Cow Symposium

Our goal at Deseret Land and Livestock is to maximize long-term profit. Our profit is a function of the following factors: the prices we receive for our production, our amount of production, the costs of production, and the productive capabilities of our land and labor. Prices, production, and cost are managed on an annual basis. The long-term outcome of one’s management is determined by their attention and skill in enhancing the capability of land and labor.

These factors of profit can vary tremendously within and between years. For example, prices for 400-500 pound steer calves from 1979-1989 varied nearly $.58/pound …

Biotechnology – Harnessing An Exciting New Tool For Beef Production, Burke Healey

Range Beef Cow Symposium

As ranchers and cattle breeders we are entering what may well be the most exciting decade of our era. A new tool has been unleashed. That tool is biotechnology. Yes, the future is here. All we have to do is harness this amazing breakthrough.

Characteristics Of Diverse Breeds In Cycle Iv Of The Cattle Germ Plasm Evaluation Program At The U.S. Meat Animal Research Center, Larry V. Cundiff, Keith Gregory, R. M. Koch, John D. Crouse, Michael E. Dikeman

Range Beef Cow Symposium

Breed differences in performance characteristics are an important genetic resource for improving efficiency of beef production. Diverse breeds are required to exploit heterosis and complementarity through crossbreeding and new composite breeds and to match genetic potential with diverse markets, feed resources and climates. This report presents preliminary results from an ongoing study at the Roman L. Hruska U.S. Meat Animal Research Center (MARC) to characterize breeds of cattle representing diverse biological types for traits that influence quantity and value of production.

Management Strategies For Improving The Re-Breeding Of The Cow, James E. Kinder, Leree A. Werth

Range Beef Cow Symposium

What are the primary factors that influence the ability of cows to rebreed following calving? From a broad perspective, two key factors influence when conception occurs. First, cows must initiate estrous (heat) cycles following calving to provide the proper conditions for conception to be possible. Secondly those events involved in conception must occur. We will discuss what has to occur before estrous cycles are initiated. The influence of the presence of bulls on initiation of estrous cycles is emphasized. In the second section of the paper, we describe conception rates in 2 and 3 year old cows during the early …

Managing Cow Calf Resources, Bob Taylor

Range Beef Cow Symposium

Effective management involves the decision-making process whereby success can be achieved. Success is the progressive realization of worthwhile goals.

A realistic management goal for profit-oriented cow-calf producers is as follows:

Manage the available resource (optimum combination) for maximum continuing net profit while conserving and improving the resources.

Cow-calf operations have several resource areas that must be profitably managed. These resources are land (forage), cattle, markets, equipment, human (hired labor, management and family) and possibly others. Biological and economical relationships within and between these resource areas that affect productivity and profitability must be understood and managed.

Without question, the human resource …

If Immunity Fails, Don’T Pick On Your Drug Salesman – It May Be Nutritional, Cheryl F. Nockels

Range Beef Cow Symposium

“But I vaccinated those calves for enterotoxemia, they couldn’t have died from Clostridium perfringens. That vaccine must not be any good! Just wait until I get hold of that drug company salesperson.” Does this scenario or a similar experience seem familiar to you? I’m not saying that there aren’t times when vaccines fail to cause the animal to produce its own protective response by stimulating the immune system. A substance foreign to the body that induces the immune system to response is called an antigen, as found in vaccines or organisms such as bacteria or viruses. An animal’s immunological …

Instrumental Valuation Indicators For Natural Resources And Ecosystems, F. Gregory Hayden

Department of Economics: Faculty Publications

Beldon Daniels, in the early draft of his latest book, which has a working title of Rediscovering America, 1992, has written that there have been four major eras in human history. The fourth, into which we are now evolving, according to Daniels, is the age of intelligence. Although the intelligence activity of the modern age both uses and directs the development of large quantities of data, information, and knowledge; a measurement concept, or unit for valuation has yet to be developed. The industrial age from which we are evolving, consistent with the technology of that era, has used industrial …

Stings Of Ants Of The Tribe Ectatommini (Formicidae: Ponerinae), Charles Kugler

Insecta Mundi

The sting apparatus anatomy is described and compared for 24 species in six of the 9 extant genera of Ectatommini: Paraponera, Acanthoponera, Gnamptogenys, Ectatomma, Proceratium, and Discothyrea. Phylogenetic analysis sorts 15 species of Gnamptogenys into four species groups. Phylogenetic analyses on the six ectatommine genera suggest that: 1) Gnamptogenys and Ectatomma are sister genera, 2) Proceratium and Discothyrea are sister genera, 3) Acanthoponera may be more related to Gnamptogenys and Ectatomma than to the others, and 4) Paraponera may not belong with the other five genera.

Phylogenetic Analysis Of Alloglossidium Simer, 1929 (Digenea: Plagiorchiiformes: Macroderoididae) With Discussion Of The Origin Of Truncated Life Cycle Patterns In The Genus, Joseph P. Carney, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alloglossidium comprises 9 species of North American plagiorchiiform digeneans using ictalurid catfish, freshwater crustacea, and hirudinid leeches as definitive hosts. Two hypotheses about the evolution of this array of definitive hosts were examined using phylogenetic systematic analysis. Two most parsimonious trees, based on 15 homologous series derived from morphological data, each indicated the two species utilizing ictalurid catfish definitive hosts are basal members of the group, whereas the two species using freshwater crayfish definitive hosts and the five utilizing leech definitive hosts each comprise relatively derived monophyletic sister groups. The results suggest that species using crustaceans as definitive hosts are …

A Novel Transposon Trap For Mycobacteria: Isolation And Characterization Of Is1096, Jeffrey D. Cirillo, Raul G. Barletta, Barry R. Bloom, William R. Jacobs Jr.

School of Veterinary and Biomedical Sciences: Faculty Publications

In the course of developing strategies to obtain a mutation in the aspartate semialdehyde dehydrogenase (asd) gene of Mycobacterium smegmatis, an efficient transposon trap was constructed which may be generally useful for the identification of transposable elements in mycobacteria. A DNA fragment containing the asd gene was replaced with an aminoglycoside phosphotransferase gene (aph) to generate a Δasd::aph allele. Attempts to replace the wild-type asd gene with the Δasd::aph allele were unsuccessful, suggesting that this deletion was lethal to the growth of M. smegmatis. The plasmid, pYUB215, which …

A Conservation Tillage Educational Program, Elbert C. Dickey, Paul J. Jasa, David P. Shelton

Department of Agricultural and Biological Systems Engineering: Faculty Publications

An educational program was conducted to enhance the adoption of conservation tillage practices in targeted areas to reduce soil erosion and on-farm fuel use. Traditional extension methods such as meetings, field days, demonstrations, and plots were used extensively. In addition, the following nontraditional educational methods were used to achieve project objectives: targeting high priority areas, local program guidance committees, surveys to evaluate perceptions and use of conservation tillage, employment of extension assistants to work in the target areas, use of a rainfall simulator to demonstrate the effectiveness of residue cover in reducing erosion, and small group or "coffee shop" meetings …

1992 Beef Cattle Report, Darrell W. Nelson

Nebraska Beef Cattle Reports

Economic efficiency of beef production to weaning and to slaughter was estimated in three groups, different in milk available (low, medium, and high) to the calves but the same in growth potential. Efficiency was the ratio of income to expenses. Income was derived from cull cows and calves at weaning or carcasses of calves fed to slaughter. Feed and non-feed expenses for the cowherd and for calves to weaning or to slaughter were included. Efficiencies were estimated assuming observed reproductive rates and energy requirements for maintenance, as well as for equal reproductive rates and equal requirements for maintenance in the …
