G03-1485 Guidelines For The Prudent Use Of Antibiotics In Food Animals, Katherine Irwin, David R. Smith, Grasso M. Ebako, Steve Ensley, Dicky D. Griffin, Arden Wohlers
G03-1485 Guidelines For The Prudent Use Of Antibiotics In Food Animals, Katherine Irwin, David R. Smith, Grasso M. Ebako, Steve Ensley, Dicky D. Griffin, Arden Wohlers
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide explains why antibiotics must be used with care and how to prudently use antibiotics to treat food animals.
Antibiotics are used to improve animal health and productivity. You, the animal caregiver, make important decisions about how antibiotics are finally used in food producing animals. Antibiotics should be used prudently to ensure they are effective, do not leave residues in food, and will continue to benefit man and animals in the future. Are you prepared to make the best decisions about using antibiotics in animals?

This NebGuide explains why antibiotics must be used with care and how to prudently use antibiotics to treat companion animals.
Antibiotics are used to improve animal health and performance. You, as the animal owner or caregiver, make important decisions about how antibiotics are finally used in companion animals. Antibiotics should be used prudently to ensure they are effective and will continue to benefit man and animals in the future. Are you prepared to make the best decisions about using antibiotics in animals?

Submersed Aquatic Vegetation Trends In Impounded And Backwater Habitat Types Of Pool 13, Upper Mississippi River System: 1994-2000, Theresa A. Blackburn, Daniel J. Kirby
Submersed Aquatic Vegetation Trends In Impounded And Backwater Habitat Types Of Pool 13, Upper Mississippi River System: 1994-2000, Theresa A. Blackburn, Daniel J. Kirby
Journal of the Iowa Academy of Science: JIAS
Submersed aquatic vegetation (SAV) was sampled from 1994-2000 at fixed sires along established transects in Pool 13 of the Upper Mississippi River System (UMRS), as part of the Long Term Resource Monitoring Program (LTRMP). These data were used to quantify the annual percent frequency of occurrence and mean relative density of SAV within three backwaters (Brown's Lake, Savanna Bay, and Spring Lake) and the impounded area of Pool 13. This investigation used Spearman rank correlation to assess the strength of bivariate relationships between measurements of SAV abundance and biological, physical, and hydrological variables at fixed water quality monitoring sites within …
Restoration And Monitoring Of The River Otter Population In Iowa, J. A. Pitt, W. R. Clark, R. D. Andrews, K. P. Schlarbaum, D. D. Hoffman, S. W. Pitt
Restoration And Monitoring Of The River Otter Population In Iowa, J. A. Pitt, W. R. Clark, R. D. Andrews, K. P. Schlarbaum, D. D. Hoffman, S. W. Pitt
Journal of the Iowa Academy of Science: JIAS
Northern river otters (Lontra canadensis) were widespread in North America at the time of European settlement. However, river otters were extirpated from most of Iowa in the early 1900s due to habitat degradation and unregulated harvest. In 1985, the Iowa Department of Natural Resources began an effort to restore the river otter population throughout the state, including a pilot study of survival to determine if establishment was feasible. Annual survival was estimated to be 86% during the pilot study. River otters dispersed an average of about 11 km from the point of release and exhibited habitat use typical for the …
Occurrence Of Ovotestes And Plasma Vitellogenin In Feral Male Fathead Minnows From Lagoons Of Municipal Wastewater Treatment Facilities In Central Iowa, Robert B. Bringolf, Robert C. Summerfelt
Occurrence Of Ovotestes And Plasma Vitellogenin In Feral Male Fathead Minnows From Lagoons Of Municipal Wastewater Treatment Facilities In Central Iowa, Robert B. Bringolf, Robert C. Summerfelt
Journal of the Iowa Academy of Science: JIAS
Since the early 1990s, endocrine disrupting compounds have been recognized as an important environmental threat. Male fish exposed to effluent from large, metropolitan municipal wastewater treatment facilities (WWTFs) have developed reproductive abnormalities including ovotestes and elevated levels of plasma vitellogenin (Vtg), a plasma protein typically produced by egg-laying females. In the summer of 2000, gonads and plasma Vtg concentrations were examined in feral male fathead minnows (Pimephales promelas) collected from lagoons of 11 small, rural municipal WWTFs and a reference site (a national wildlife refuge) in Iowa. Fathead minnows were captured in traps from five of the 33 lagoons (three …

A Key To The Eggs And Nests Of Iowa Turtles, James L. Christiansen, Jeffrey R. Parmelee
A Key To The Eggs And Nests Of Iowa Turtles, James L. Christiansen, Jeffrey R. Parmelee
Journal of the Iowa Academy of Science: JIAS
Biologists often need to identify destroyed turtle nests where a predator has excavated and eaten the eggs. We present a dichotomous key to the eggs and nests of Iowa's turtles based on egg or nest morphology and known range of the species. Egg and nest morphology clearly separated most nests of the families Chelydridae and Kinosternidae and many of the Emydidae. However, egg morphology must be combined with known range to distinguish wood turtles (Glyptemys insculpta) from other emydids. These factors will also separate most false map turtles (Graptemys pseudogeographica) from other species. Similarities among egg morphologies, nest morphologies, and …
The Influence Of Soil Water Content, Calcite Content, And Temperature On Bulk Electrical Conductivity, Eric C. Brevik, Jaehoon Lee, Thomas E. Fenton, Robert Horton
The Influence Of Soil Water Content, Calcite Content, And Temperature On Bulk Electrical Conductivity, Eric C. Brevik, Jaehoon Lee, Thomas E. Fenton, Robert Horton
Journal of the Iowa Academy of Science: JIAS
Electrical conductivity (EC) as measured by the Geonics® EM-38 has shown promise as a soil survey tool. EC is determined by a combination of soluble salts, clay content and mineralogy, water content, and temperature. While investigating use of the EM-38 for soil survey purposes, it is important to understand the relative contribution of each of these variables on EC. A laboratory experiment was set up to determine the relative influence of water content, temperature, and calcite content on EC using time-domain reflectometry (TDR) probes. TDR was used as a proxy for the EM-38 because of the large volume of soil …

Effects Of Student Ontological Position On Cognition Of Human Origins, Jeremy Ervin
Effects Of Student Ontological Position On Cognition Of Human Origins, Jeremy Ervin
Faculty Dissertations
In this study, the narratives from a hermeneutical dialectic cycle of three high school students were analyzed to understand the influences of ontological position on the learning of human origins. The interpretation of the narratives provides the reader an opportunity to consider the learning process from the perspective of worldview and conceptual change theories. Questions guiding this research include: Within a context of a worldview, what is the range of ontological positions among a high school AP biology class? To what extent does ontological position influence the learning of scientific concepts about human origins? If a student’s ontological position is …
Design And Application Of A Nutrition Education Program Based On A Test Of Improved Practices For Pregnant Women And Women Of Childbearing Age In La Rinconada And Cuambo, Odila Nicaragua
Theses and Dissertations
This study was done with the objective of designing and applying a nutrition education program based on a test of improved practices for pregnant women and women of childbearing age in the rural communities of Ibarra canton: La Riconada and Cuambo. For this, information was collected on knowledge, attitudes, and practices (KAP) regarding the eating habits of pregnant women. These results were used to identify content and recommendations to reinforce and/or instruct about eating during pregnancy. Nutrition education was based on the methodology of the improved practices test, which consisted of testing the recommendations in families' homes before recommending them …
