Weaning Date For Spring Calving Cows Grazing Sandhills Range, Lane Ciminski, Don C. Adams, Terry J. Klopfenstein, Dick Clark, Andy Applegarth, Jacqueline A. Musgrave, Russ Sandberg

Nebraska Beef Cattle Reports

A two-year experiment was conducted with March calving cows to determine the effect of the weaning date on cow body condition score, cow body weight, and calf body weight. Treatments were of eight weaning dates imposed at consecutive two-week intervals, beginning in mid-August and ending in late November. Cow body condition score declined linearly as weaning date was later in the fall. Calf body weight gains from August through November increased with weaning dates from August 18 through October 13; however, weaning after October 13 provided no advantage of increased calf body weight gain.

Prosocial Development In Early Adulthood: A Longitudinal Study, Nancy Eisenberg, Ivanna K. Guthrie, Amanda Cumberland, Bridget C. Murphy, Stephanie A. Shepard, Qing Zhou, Gustavo Carlo

Department of Psychology: Faculty Publications

Consistency of measures of a prosocial personality and prosocial moral judgment over time, and the interrelations among them, were examined. Participants’ and friends’ reports of prosocial characteristics were obtained at ages 21– 22, 23–24, and 25–26 years. In addition, participants’ prosocial judgment was assessed with interviews and with an objective measure of prosocial moral reasoning at several ages. Reports of prosocial behavior and empathy-related responding in childhood and observations of prosocial behavior in preschool also were obtained. There was interindividual consistency in prosocial dispositions, and prosocial dispositions in adulthood related to empathy/sympathy and prosocial behavior at much younger ages. Interview …

Integrating Science In Agricultural Education: Attitudes Of Indiana Agricultural Science And Business Teachers, Mark Balschweid, Gregory W. Thompson

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

The purpose of this study was to determine how Indiana Agricultural Science and Business (ASB) teachers perceived the impact of integrating science on agricultural education programs. The population consisted of all Indiana ASB teachers employed during the fall 1999 semester (N = 243). The Integrating Science Survey Instrument developed by Thompson (1996) was used to identify the perceptions of the ASB instructors. From the data it was concluded that many of Indiana’s Agricultural Science and Business instructors have responded positively to the call for the integration of science into the agricultural education curriculum. As a result of their efforts, over …

A Baiting System For Delivery Of An Oral Plague Vaccine To Black-Tailed Prairie Dogs, Terry E. Creekmore, Tonie E. Rocke, Jerry Hurley

United States Department of Agriculture Wildlife Services: Staff Publications

Laboratory and field studies were conducted between July and October 1999 to identify bait preference, biomarker efficacy, and bait acceptance rates for delivering an oral plague vaccine to black-tailed prairie dogs (Cynomys ludovicianus). Twenty juvenile captive prairie dogs were offered alfalfa baits containing either alfalfa, alfalfa and 5% molasses, or alfalfa, 5% molasses and 4% salt. Based on the results of these trials we selected a bait containing alfalfa, 7% molasses, and 1% salt for field trials to determine bait acceptance rates by free-ranging animals. The biomarkers DuPont Blue dye, iophenoxic acid, and tetracycline hydrochloride were orally administered …

A Swat/Microbial Sub-Model For Predicting Pathogen Loadings In Surface And Groundwater At Watershed And Basin Scales, Ali M. Sadeghi, Jeffrey G. Arnold

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Despite the many potential sources of release of pathogenic organisms into the environment, agronomic practices that utilize animal manures contaminated with pathogenic or parasitic organisms appear to be the major contributors to watershed or basin contaminations. High rates of land-applied raw manure increase the risks of surface or ground water contamination, both from excess nutrients and pathogenic organisms. Unfortunately, current technologies are not adequate for handling large-scale treatment processes (e.g., composting, digestion, etc.) for stabilizing human pathogens in animal manures before application to agricultural lands. Therefore, there is a need for modeling capabilities to assess risks associated with individual and …

Resistance Of Tripsacorn To Sitophilus Zeamais And Oryzaephilus Surinamensis, James E. Throne, Mary W. Eubanks

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

One strategy that has been used to find germplasm for developing improved plant varieties is to test ancestral germplasm for the desired traits. Although the progenitors of commercial maize are not known, a hybrid (called Tripsacorn) developed from a perennial teosinte, Zea diploperennis, and eastern gamagrass, Tripsacum dactyloides, resembles the earliest known samples of primitive domesticated maize. We tested resistance of whole Tripsacorn to the primary storage pest (primary storage pests can infest intact kernels) the maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), and resistance of ground Tripsacorn to the secondary storage pest (secondary pests usually cannot infest …

Killing Of Mycobacterium Avium Subspecies Paratuberculosis Within Macrophages, John P. Bannantine, Judith R. Stabel

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Background: Mycobacterium avium subspecies paratuberculosis (M. paratuberculosis) is a facultative intracellular pathogen that resides within host macrophages during infection of ruminant animals. We examined survival of M. paratuberculosis infections within cultured macrophages to better understand the interplay between bacterium and host.

Results: Serial plating of M. paratuberculosis infected macrophage lysates on Herold's egg yolk medium showed that mycobacterial replication takes place between 0 and 24 hours post-infection. This initial growth phase was followed by a steady decline in viability over the next six days. Antibodies against M. paratuberculosis were affinity purified and used in conjunction with transmission electron microscopy to …

Kura Clover And Birdsfoot Trefoil Response To Soil Ph, L. R. Dehaan, M. P. Russelle, C. C. Sheaffer, N. J. Ehlke

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Use of the rhizomatous perennial forage legume kura clover (Trifolium ambiguum M. Bieb.) has been limited by slow establishment. Mature kura clover responds to liming on some acid soils, but the soil pH required for vigorous growth of young plants is unknown. A factorial greenhouse experiment was conducted with two kura clover cultivars (Rhizo and Endura) and one cultivar of birdsfoot trefoil (Lotus corniculatus L., Norcen) planted in three soil types (Sartell loamy fine sand, Hubbard loamy sand, and Sanborg clay loam) amended with Ca(OH)₂ to obtain six soil pH levels. The experiment was performed twice, once …

Mutual Interference Of Pheromone Traps Within Trap Lines On Captures Of Boll Weevils (Coleoptera: Curculionidae), Thomas W. Sappington

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Traps baited with the synthetic aggregation pheromone of the boll weevil (Anthonomus grandis Boheman) are often used to monitor population fluctuations, distribution, and behavior. However, many factors generate variability in daily captures, making interpretation of trapping data difficult. Previous studies have shown that wind speed in the microenvironment around a trap can greatly affect numbers captured on a given day. It is possible that variation in air movement may also generate variation in trap captures through its effects on the pheromone plume. The current study was conducted to determine whether five traps placed in a line at two commonly …

A Personal Account Of Creating The Sterile Insect Technique To Eradicate The Screwworm From Curacao, Florida And The Southeastern United States, Alfred H. Baumhover

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The history is recounted of developing the sterile insect technique to eradicate the screwworm, Cochliomyia hominivorax (Coquerel), from the Caribbean island of Curacao, Florida and the southeastern U.S. Observations of screwworm biology and challenges faced in conducting these eradication projects are described by the author who worked on all aspects of the research and field operations. Eradication was first demonstrated on Curacao, essentially a 170 mi² outdoor laboratory. The population dynamics of the wild screwworm was determined and overflooding ratios and dispersal patterns essential for population suppression were defined. Eradication was achieved with minimal resources by attacking the pest …

Threat Of Foreign Arthropod-Borne Pathogens To Livestock In The United States, Ralph A. Bram, John E. George, Robert E. Reichard, Walter J. Tabachnick

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

There are many exotic animal pathogens throughout the world that, if introduced into the United States, could have a significant detrimental impact on the health of livestock, agricultural economy, the environment, and public health. Many of these pathogens are arthropod-borne and potential vectors are readily available in the United States. A number of these arthropod-borne pathogens are discussed here as examples that illustrate the potential risk and the consequences of inadvertent introductions. Several International agencies have a role in global surveillance and in controlling animal diseases should they begin to expand their range. The risk to the United States is …

Soil- And Plant-Water Dynamics In A C3/C4 Grassland Exposed To A Subambient To Superambient Co2 Gradient, H. Wayne Polley, Hyrum B. Johnson, Justin D. Derner

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Plants may be more sensitive to carbon dioxide (CO₂) enrichment at subambient concentrations than at superambient concentrations, but field tests are lacking. We measured soil-water content and determined xylem pressure potentials and δ¹³C values of leaves of abundant species in a C3/C4 grassland exposed during 1997-1999 to a continuous gradient in atmospheric CO₂ spanning superambient concentrations (200-560 µmol mol^-1).

Fish Species-Richness Trends In The Niobrara River, Nebraska, Below The Spencer Dam, Michael P. Gutzmer, Justin W. King, David P. Overhue, Ed Y. Chrisp

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Nebraska Public Power District (NPPD) has monitored fish populations annually (except 1998) since 1993 on the Niobrara River in Nebraska, in the vicinity of Spencer Hydropower Project before and after "flushing" or "sluicing" activities. These activities could alter water quality in the river downstream, which can negatively impact fish populations. Intensive sluicing-monitoring studies coupled with operational adjustments indicated minimal impacts were occurring to fish populations in the vicinity of the hydro. Long-term diversity and abundance of fish species has been a historical concern, so annual fish sampling has continued through the present. Of the 13,063 fishes in 26 species sampled …
