Ec05-473 Functional Foods, Theresa Herring, Julie A. Albrecht Jan 2005

Ec05-473 Functional Foods, Theresa Herring, Julie A. Albrecht

University of Nebraska-Lincoln Extension: Historical Materials

Just as consumers grew weary of hearing about the bombardment of foods that contain unhealthy, disease-causing components, researchers and nutrition educators have shifted their focus to the study and promotion of functional foods. Foods that have physiologically active components, which can improve one's health and prevent disease beyond that of one's essential daily nutritional requirements, are called functional foods.

This Extension Circular defines functional foods. It reviews food label rules for functional foods, their physiologically active components, and their specific health benefits. Examples are provided of the advantages of whole food consumption compared to one isolated component. Key definitions are …


Nf05-624 Omega-3 Fatty Acids, Jennifer Larsen, Linda S. Boeckner Jan 2005

Nf05-624 Omega-3 Fatty Acids, Jennifer Larsen, Linda S. Boeckner

University of Nebraska-Lincoln Extension: Historical Materials

Fats in our food are categorized according to the predominant fatty acid that is present. Typically fats are categorized as saturafed fatty acids or unsaturated fatty acids. Some examples of foods that are high in saturated fats are butter and lard. These fats are solid at room temperature. Fats that are high in unsaturated fatty acids are liquid at room temperature. Examples are vegetable oils such as canola, corn, olive or soybean.

This NebFacts discusses the benefits of Omega-3 fatty acids, supplements, how much is enough and the cautions on eating certain fish.


Estimating Drc-1339 Mortality Using Bioenergetics: A Case Study Of European Starlings, H. Jeffrey Homan, Randal S. Stahl, John Johnston, George M. Linz Jan 2005

Estimating Drc-1339 Mortality Using Bioenergetics: A Case Study Of European Starlings, H. Jeffrey Homan, Randal S. Stahl, John Johnston, George M. Linz

Wildlife Damage Management Conference Proceedings

We developed a bioenergetics model for European starlings (Sturnus vulgaris) that estimated mortality from baitings with CU Bird Carrier pellets treated with 1% DRC-1339 Concentrate and diluted 5:1 (untreated:treated pellets). A bioenergetic analysis of heat and radiative energy exchanges between the starling body surface and surrounding environment was converted to daily caloric demand based on a steady-state energy balance. The amount of Bird Carrier eaten per starling was governed by subroutines in the model that used probability distributions to simulate variability in dietary intake at the bait site. Mortality was estimated through dose-response regression analysis. Compared to onsite …


Deer-Vehicle Crash Patterns Across Ecoregions In Michigan, Krishnan Sudharsan, Shawn Riley, Brent Riley, Brian Maurer Jan 2005

Deer-Vehicle Crash Patterns Across Ecoregions In Michigan, Krishnan Sudharsan, Shawn Riley, Brent Riley, Brian Maurer

Wildlife Damage Management Conference Proceedings

Deer-vehicle collisions (DVCs) impact the economic and social well being of humans. We examined large-scale patterns behind DVCs across 3 ecoregions: Southern Lower Peninsula (SLP), Northern Lower Peninsula (NLP), and Upper Peninsula (UP) in Michigan. A 3 component conceptual model of DVCs with drivers, deer, and a landscape was the framework of analysis. The conceptual model was parameterized into a parsimonious mathematical model. The dependent variable was DVCs by county by ecoregion and the independent variables were percent forest cover, percent crop cover, mean annual vehicle miles traveled (VMT), and mean deer density index (DDI) by county. A discriminant function …

Helping End-Users “Engineer” Dependable Web Applications, Sebastian Elbaum, Kalyan-Ram Chilakamarri, Bhuvana Gopal, Gregg Rothermel Jan 2005

Helping End-Users “Engineer” Dependable Web Applications, Sebastian Elbaum, Kalyan-Ram Chilakamarri, Bhuvana Gopal, Gregg Rothermel

School of Computing: Conference and Workshop Papers

End-user programmers are increasingly relying on web authoring environments to create web applications. Although often consisting primarily of web pages, such applications are increasingly going further, harnessing the content available on the web through “programs” that query other web applications for information to drive other tasks. Unfortunately, errors can be pervasive in web applications, impacting their dependability. This paper reports the results of an exploratory study of end-user web application developers, performed with the aim of exposing prevalent classes of errors. The results suggest that end-users struggle the most with the identification and manipulation of variables when structuring requests to …

G05-1587 Understandng Effective Fiber In Rations For Dairy Cattle, Paul J. Kononoff Jan 2005

G05-1587 Understandng Effective Fiber In Rations For Dairy Cattle, Paul J. Kononoff

University of Nebraska-Lincoln Extension: Historical Materials

Fiber type, quality and length are key to herd health and production.

Fiber is a key component in dairy rations. When nutritionists are faced with herd challenges such as low milkfat tests, foot problems, or low feed conversions, ration fiber often is evaluated. Effective fiber depends on the type and amount of forages and nonforage fiber sources being fed, the particle size of those forages and the amount of available nonfiberous carbohydrates included in the diet.


Phosphorus And Dairy/Beef Nutrition, Larry D. Satter, Terry J. Klopfenstein, Galen E. Erickson, J. Mark Powell Jan 2005

Phosphorus And Dairy/Beef Nutrition, Larry D. Satter, Terry J. Klopfenstein, Galen E. Erickson, J. Mark Powell

Department of Animal Science: Faculty Publications

Phosphorus (P), a required nutrient for all livestock, has numerous essential physiological functions in the body that include energy transfer (ATP), structure of bone, teeth, and membranes, and buffering pH changes in the rumen (salivary phosphate). Ruminants use a larger proportion of dietary P than nonruminants because rumen microbes produce phytase, the enzyme that hydrolyzes P from phytate. The majority of P in most grains is in phytate form, a P form largely unavailable to swine and poultry.


Comparison Of A Corn Silage Hybrid With High Cell-Wall Content And Digestibility With A Hybrid Of Lower Cell-Wall Content On Performance Of Holstein Cows, S. K. Ivan, R. J. Grant, D. Weakley, J. Beck Jan 2005

Comparison Of A Corn Silage Hybrid With High Cell-Wall Content And Digestibility With A Hybrid Of Lower Cell-Wall Content On Performance Of Holstein Cows, S. K. Ivan, R. J. Grant, D. Weakley, J. Beck

Department of Animal Science: Faculty Publications

We hypothesized that substituting a corn hybrid with high cell-wall content and high neutral detergent fiber (NDF) digestibility (HCW) for a hybrid with lower cellwall content and lower NDF digestibility (LCW) would improve feed intake and milk production in lactating Holstein cows. There was a 3.6 percentage unit difference in NDF content and a 4.1 percentage unit difference in 30-h in vitro NDF digestion between the 2 corn hybrids. In trial 1, 40 cows (12 primiparous) ranging in milk production from 24.1 to 44.0 kg/d, following a 2- wk preliminary period, were used in a crossover design with 2-wk periods. …

Genetic And Environmental Factors Associated With Incidence Of Infectious Bovine Keratoconjunctivitis In Preweaned Beef Calves, G. D. Snowder, L. Dale Van Vleck, L. V. Cundiff, G. L. Bennett

Department of Animal Science: Faculty Publications

Infectious bovine keratoconjunctivitis (IBK) is one of the most economically important diseases in preweaned calves. This study examined the health records of 45,497 calves over a 20-yr period to determine environmental and genetic factors influencing the incidence of IBK. Three data sets were analyzed with an animal model. The first data set (n = 41,986) evaluated environmental factors and genetic differences among nine purebred (Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Pinzgauer, Red Poll, and Simmental) and three composite breeds (MARC I, MARC II, and MARC III). Weaning weights of calves diagnosed with IBK were 8.9 kg lighter (P < 0.05) than weights of healthy calves. Incidence of IBK was related to age of the calf and the seasonal life cycle of the face fly (Musca autumnalis …


Optimal Wet Corn Gluten And Protein Levels In Steam-Flaked Corn-Based Finishing Diets For Steer Calves, H. C. Block, C. N. Macken, Terry Klopfenstein, Galen E. Erickson, Rick Stock Jan 2005

Optimal Wet Corn Gluten And Protein Levels In Steam-Flaked Corn-Based Finishing Diets For Steer Calves, H. C. Block, C. N. Macken, Terry Klopfenstein, Galen E. Erickson, Rick Stock

Department of Animal Science: Faculty Publications

A feeding trial evaluated the hypothesis that wet corn gluten feed would improve growth performance of cattle fed steam-flaked corn-based finishing diets and supply required degradable intake protein (DIP). The trial used 360 steer calves (initial BW = 288 ± 11 kg) housed in 36 pens for 166 d in an incomplete 4 × 3 factorial arrangement of treatments. Pens of steers were assigned to treatments according to a completely randomized design (four replicates per treatment combination). Treatments were wet corn gluten feed (0, 20, 30, or 40% of dietary DM) and CP (13.0, 13.7, or 14.4% of dietary DM) …


Foraging Behaviors Of Alouatta Palliata, Mantled Howling Monkeys, Jeffrey A. Baum Jan 2005

Foraging Behaviors Of Alouatta Palliata, Mantled Howling Monkeys, Jeffrey A. Baum

Nebraska Anthropologist

Research was conducted at the EI Zota biological field station to determine the amount and type of food processing exhibited by mantled howling monkeys (Alouatta palliata) prior to consumption. Mantled howling monkeys have been labeled as behavioral folivores with limited morphological adaptations for foliage digestion. The purpose of this study was to determine if A. palliata displayed any food manipulations and how food was selected by the species. Breakdown of the data was done to evaluate differences based on sex for these feeding and foraging behaviors. Results showed no behaviors that could be classified as manipulating food items …


Theory Of Mind In Chimpanzees: A Rationalist Approach, Benjamin Grant Purzycki Jan 2005

Theory Of Mind In Chimpanzees: A Rationalist Approach, Benjamin Grant Purzycki

Nebraska Anthropologist

The question of whether or not chimpanzees possess the ability to mentally represent others' mental states has been a popular question since Premack and Woodruff (1978) originally asked the question. It is well established that humans have a theory of mind (ToM), but extending this psychological faculty to our evolutionary cousins has created a massive amount of literature and research attempting to resolve this issue. Such a resolution is arguably not possible given the nature of the debate. An Either/Or approach to chimpanzee theory of mind both ignores the essential components of ToM as well as foreclosing on the possibility …


Postpartum Depression: An Evolutionary Perspective, Mark Tracy Jan 2005

Postpartum Depression: An Evolutionary Perspective, Mark Tracy

Nebraska Anthropologist

There is no common consensus among theorists regarding the nature and purpose of postpartum depression. Evolutionary theorists have proposed that the onset of postpartum depression is an adaptive function that signals a potential fitness cost to the mother i. e. the investment in the child will be cost more than the evolutionary benefits to be gained from rearing this child Many studies have shown that there is a strong correlation between postpartum depression and lack of paternal or social support indicating that when these two variables are absent the mother is more likely to experience postpartum depression. In this paper …


Seasonal Acceptance Of Fourwing Saltbush By Sheep When Crested Wheatgrass Is The Alternative, Christine W. Royer, R. D. Horrocks, Val J. Anderson, Stephen B. Monsen Jan 2005

Seasonal Acceptance Of Fourwing Saltbush By Sheep When Crested Wheatgrass Is The Alternative, Christine W. Royer, R. D. Horrocks, Val J. Anderson, Stephen B. Monsen

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

Many sagebrush-grass ranges have been seeded to crested wheatgrass [Agropyron desertorum (Fischer ex Link) Shultes]. These ranges are generally nutritionally inadequate for sheep (Ovis aries L.), except for short grazing periods in the spring and fall. To increase production and diversity, particularly crude protein for late-season grazing, fourwing saltbush [Atriplex canescens (Pursch.) Nutt.] was planted in an existing stand of crested wheatgrass. Quantification of sheep forage preferences on these improved ranges aids in determining the length of the grazing season and the extent to which shrubs provide the supplemental nutrition required. This seasonal grazing study was conducted …

Herbivory Alters Resource Allocation And Compensation In The Invasive Tree Melaleuca Quinquenervia, P. D. Pratt, M. B. Rayamajhi, T. K. Van, T. D. Center, P. W. Tipping

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

The Australian native Melaleuca quinquenervia is highly invasive in the Florida Everglades, U.S.A., where it experiences limited competition or herbivory from native species, making it a likely candidate for compensation. The introduced biological control agent Oxyops vitiosa feeds exclusively on the seasonal flushes of developing foliage at branch apices, which represents ~ 15% of the total foliar biomass.


Maintenance Of A Narrow Host Range By Oxyops Vitiosa; A Biological Control Agent Of Melaleuca Quinquenervia, G. S. Wheeler Jan 2005

Maintenance Of A Narrow Host Range By Oxyops Vitiosa; A Biological Control Agent Of Melaleuca Quinquenervia, G. S. Wheeler

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

Host range expansion in insect herbivores is often thought to be mediated by several factors, principal among them are secondary plant metabolites. In weed biological control, the host range of a prospective agent is one of the most important considerations in its implementation. Extensive host testing tests seek to determine the behavioral acceptance and nutritional value of different test plant species to the potential agent. A list of test plants is compiled that comprises species that are close taxonomic relatives of the target weed plus other species of economic or ecologic importance. The host testing of the Melaleuca quinquenervia biological …

Morbidity And Mortality Factors In Pre-Fledged Florida Sandhill Crane (Grus Canadensis Pratensis) Chicks, Robert J. Dusek, Marilyn G. Spalding, Donald J. Forrester, Nicholas Komar, Jonathan F. Day Jan 2005

Morbidity And Mortality Factors In Pre-Fledged Florida Sandhill Crane (Grus Canadensis Pratensis) Chicks, Robert J. Dusek, Marilyn G. Spalding, Donald J. Forrester, Nicholas Komar, Jonathan F. Day

Proceedings of the North American Crane Workshop

One hundred and fifteen Florida sandhill crane (Grus canadensis pratensis) chicks were captured in Osceola and Lake Counties, Florida in 1998 - 2000 and examined for evidence of disease. Evidence of Eimeria gruis and/or E. reichenowi infection was found in 52% of chicks examined. Ten chicks were positive for antibodies to St. Louis encephalitis virus and 1 of these chicks was also positive for antibodies to eastern equine encephalitis virus. Predation was the most commonly identified cause of mortality. An unidentified microfilaria, and an unknown protozoan were detected in blood smears from crane chicks. A number of other …


Sandhill Crane Use Of Managed Chufa Wetlands In New Mexico, John P. Taylor, Loren M. Smith Jan 2005

Sandhill Crane Use Of Managed Chufa Wetlands In New Mexico, John P. Taylor, Loren M. Smith

Proceedings of the North American Crane Workshop

Natural wetland food plants help meet energetic requirements for sandhill cranes (Grus canadensis). Chufa (Cyperus esculentus) tubers were found to be a prominent item in the winter diet of cranes in New Mexico and Texas. In 1996 and 1997, chufa production was compared among mowing, discing, and sustained-flooding treatments intended to enhance chufa tuber growth. Sandhill crane numbers were monitored on wetlands during winter flooding to determine treatment preferences. No differences in sandhill crane use of treated wetlands were found in 1996, however in 1997, crane use was higher on disked field than sustained flood fields …


Factor Structure And Construct Validity Of The Anxiety Sensitivity Index Among Island Puerto Ricans, Jennifer A. Cintrón, Michele M. Carter, Sonia Suchday, Tracy Sbrocco, James Gray Jan 2005

Factor Structure And Construct Validity Of The Anxiety Sensitivity Index Among Island Puerto Ricans, Jennifer A. Cintrón, Michele M. Carter, Sonia Suchday, Tracy Sbrocco, James Gray

Uniformed Services University of the Health Sciences

The factor structure and convergent and discriminant validity of the Anxiety Sensitivity Index (ASI) were examined among a sample of 275 island Puerto Ricans. Results from a confirmatory factor analysis (CFA) comparing our data to factor solutions commonly reported as representative of European American and Spanish populations indicated a poor fit. A subsequent exploratory factor analysis (EFA) indicated that a two-factor solution (Factor 1, Anxiety Sensitivity; Factor 2, Emotional Concerns) provided the best fit. Correlations between the ASI and anxiety measures were moderately high providing evidence of convergent validity, while correlations between the ASI and BDI were significantly lower providing …
