Observations On Small Mammals Recovered From Owl Pellets From Nebraska, Jeffrey J. Huebschman, Patricia W. Freeman, Hugh H. Genoways, Jospeh A. Gubanyi

University of Nebraska State Museum: Mammalogy Papers

Mammalian remains from owl pellet material collected in 24 Nebraska counties were examined, A total of 1262 individual mammals was identified from all owl pellet material and included 19 identifiable species and 21 total genera. The most commonly consumed prey by owls across the state were Microtus (41 % of identifiable prey material), followed by Peromyscus (18%), and Reithrodontomys (11%). Significant locality information for the northern grasshopper mouse (Onychomys leucogaster), the southern bog lemming (Synaptomys cooperi), and the meadow vole (Microtus pennsylvanicus) are reported

Ec01-158 Integrating Management Objectives And Grazing Strategies On Semi-Arid Rangeland, Patrick E. Reece, Jerry D. Volesky, Walter H. Schacht

University of Nebraska-Lincoln Extension: Historical Materials

Rangelands account for about half of Nebraska's total land area or about 24 million acres. Much of these expansive natural resource areas are in the semi-arid climatic region of Nebraska where grazing management decisions have a profound effect on ranch survival.

The educational object of this circular is to explain management practices that optimize the sustainability of rangeland-based enterprises. Additionally a decision-support tool is provided for selecting grazing systems best suited to livestock production and natural resource management objectives.

Two-Stage Selection For Ovulation Rate And Litter Size In Swine — An Effective Procedure To Increase Reproductive Rate, Agustin Ruiz-Flores, Rodger K. Johnson

Nebraska Swine Reports

Litter size continues to be an important economic variable in pig production. Two determinants of litter size are ovulation rate and uterine capacity, where uterine capacity is defined as the maximum number of pigs a female can carry to parturition. When the number of fertilized ova exceeds uterine capacity embryo/fetal losses during gestation reduce litter size to that sow’s uterine capacity. This experiment tested whether litter size can be increased by direct selection for ovulation rate and uterine capacity. It was accomplished by selecting for ovulation rate (OR) and number of fully formed pigs at birth (FF) in two stages. …

Dietary Manipulation To Reduce Ammonia Concentration In Nursery Pig Facilities, Janeth J. Colina, Austin Lewis, Phillip S. Miller, Robert L. Fischer

Nebraska Swine Reports

Five trials were conducted to determine the effects of Yucca schidigera extract or calcium chloride addition to the diet on aerial ammonia concentration and growth performance in nursery pigs. Trials were divided into two groups: preliminary studies (two trials) and major study (three trials). Pigs were fed one of three diets in separate, environmentally regulated rooms: 1) Control, containing 23% CP; 2) Control diet plus 125 ppm of Yucca schidigera extract; and 3) Control plus 1.95% calcium chloride. Average daily gain (ADG), average daily feed intake (ADFI), and ADG/ADFI were recorded weekly. Aerial ammonia concentration was measured daily using aspiration …

Explanation Of Statistics Used In This Report

Nebraska Swine Reports

Pigs treated alike vary in performance due to their different genetic makeup and to environmental effect we cannot completely control. When a group of pigs is randomly allotted to treatments it is nearly impossible to get an “equal” group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling.

Valine, Isoleucine, And Histidine Supplementation Of Low-Protein, Amino Acid-Supplemented Diets For Growing Pigs, Jose L. Figueroa, Austin J. Lewis, Phillip S. Miller, Robert L. Fischer

Nebraska Swine Reports

Previous experiments have shown that when the crude protein of a growing diet is reduced from 16 to 11% there is reduced growth performance of pigs, even though the diets are supplemented with lysine, tryptophan, threonine, and methionine. To determine which amino acid was next limiting in a corn-soybean meal, low-protein (11%), amino acid-supplemented diet, we conducted three experiments. In each of the three experiments, 36 growing gilts were individually penned and fed one of six diets. The three first diets were used in all three experiments: 1) 16% crude protein (CP) positive control, 2) 12% CP neutral control, and …

Plasma Urea Concentrations Of Pigs On Commercial Operations, Robert Fischer, Phillip S. Miller, Austin Lewis

Nebraska Swine Reports

Research was conducted on commercial swine operations to determine whether plasma urea concentrations could be used as an indicator of the protein requirement of growing-finishing pigs. The research consisted of a 30-question survey and an on-farm visit to collect blood and feed samples. The survey included questions about genetics, nutrition, housing and health. Results showed that when plasma urea concentrations were analyzed across all phases of production, barrows had greater plasma urea concentrations than gilts. Plasma urea concentrations varied between the different phases of production, with nursery pigs having the lowest plasma urea concentrations, followed by growing and finishing pigs, …

Economic Value Of Ractopamine (Paylean™) For Finishing Pigs, Duane Reese, Larry L. Bitney

Nebraska Swine Reports

Ractopamine, a feed additive which improves feed efficiency, daily gain and several carcass characteristics recently became available to pork producers. An economic feasibility analysis on the feeding of 4.5, 9.0, and 18.0 g/ ton ractopamine to finishing pigs fed a 16% crude protein (0.82% lysine) corn-soybean meal diet from 150 to 240 lb was conducted. The analysis was performed in two stages: 1) an economic benefit for ractopamine was calculated from cost savings due to improved feed efficiency and daily gain, and 2) the amount of carcass premium needed per pig to recover the added cost of feeding ractopamine was …

Review: Factors Affecting Decisions On When To Calve Beef Females, L. R. Sprott, Pas G. E. Selk, D. C. Adams

West Central Research and Extension Center, North Platte

The decision of when to calve beef females is critical to production efficiency and profitability in a cow and calf enterprise. Calf production and associated costs are affected by calving season because environmental conditions, stage of production, and season of the year interact to affect nutritional status and reproductive performance. Cow and calf producers typically choose to commence calving and breeding at times of the year when weather is least stressful and forage conditions are optimal. Choosing to do so can reduce the amount of supplemental feed needed to ensure acceptable pregnancy rates, resulting in reduced annual feed costs. However, …

Tests For Cognitive Mapping In Clark’S Nutcrackers (Nucifraga Columbiana), Brett M. Gibson, Alan Kamil

Papers in Behavior in Biological Sciences

In these experiments, the authors examined the nature of the spatial information that Clark’s nutcrackers (Nucifraga columbiana) use during navigation and whether this information is represented in the form of a cognitive map. In Experiment 1, nutcrackers were able to use distal cues to locate a small hidden goal. In Experiments 2 and 3, nutcrackers were given the opportunity to develop a map of a room by viewing local subsets of the landmarks in the room at a goal during training. During transfer tests, nutcrackers were presented with a landmark panorama that was not previously seen at the …

The Prevention Of Infirm Or Monstrous Births, Michael T. Walton, Robert M. Fineman

Quidditas

From ancient times, humans have tried to improve reproductive outcome, that is, to give birth to healthy, beautiful babies. Both folk traditions and medical theories offered hope that inform or monstrous births could be avoided. While most efforts were ineffectual by modern standards, some may have been beneficial. It was not until well into the twentieth century that clearly demonstrable therapies were developed to improve birth outcomes. However, those therapies were almost as limited as the ancient techniques, in light of the possibilities of genetic therapy in the twenty-first century. In the following essay, we will look at the history …

Dialogue On The Practice Of Law And Spiritual Values, James F. Henry, Joseph Allegretti, Robert A. Baruch Bush, Dr. Sarah Cobb

Fordham Urban Law Journal

This dialogue focuses on the relationship between religious/moral values and the various methods employed to resolve legal conflicts, with a primary focus on alternative dispute resolution techniques. General topics touched on include the intangible benefits of ADR (such as better relationships, transformative potential, and the effectiveness of apology) and new moral/ethical problems involved with practicing ADR. Joseph Allegretti explores two questions: (1) why Christianity provides a theoretical justification for ADR, and (2) what a Christian approach to ADR might look like. In an essay exploring the Jewish perspective on ADR, Robert Baruch Bush analyzes the Talmud's explicit preference for judges …

Is Coppa A Cop Out? The Child Online Privacy Protection Act As Proof That Parents, Not Government, Should Be Protecting Children's Interests On The Internet, Melanie L. Hersh

Fordham Urban Law Journal

This Note first presents a historical background of media regulations protecting children, and introduces COPPA. Next, it presents the arguments fueling the debate about who should regulate the Internet - the government or non-government entities. It then argues that in light of COPPA's shortcomings and faulty attempts to emulate regulations of other media, the government should step back and allow parents to maintain the bulk of regulatory responsibility. Finally, it suggests a future course of action for successfully regulating the Internet to protect children's privacy while taking into account the Internet's dissimilarity to previously regulated media. This Note concludes that …
