Genetic Variation Among Canada Wildrye Accessions From Midwest Usa Remnant Prairies For Biomass Yield And Other Traits, Kenneth P. Vogel, A. A. Hopkins, K. J. Moore, K. D. Johnson, I. T. Carlson Jan 2006

Genetic Variation Among Canada Wildrye Accessions From Midwest Usa Remnant Prairies For Biomass Yield And Other Traits, Kenneth P. Vogel, A. A. Hopkins, K. J. Moore, K. D. Johnson, I. T. Carlson

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

Canada wildrye (Elymus canadensis L.) and Virginia wildrye (Elymus virginicus L.), which are native to the USA, were collected from remnant Midwest prairies. The objectives of this study were to determine the genetic variability among the collected accessions for biomass yield and other traits, determine the extent of genotype 3 environment interactions for these traits across Midwest environments, and to determine the relationship between the geographical location of the collection site and evaluation sites for these accessions for plant biomass yield which can be used as a measure of adaptation. Seed collected from six Midwest states was bulked …

A Mathematical Model For The Validation Of Safe Air-Blast Chilling Of Cooked Hams, L. J. Wang, A Amézquita, Curtis L. Weller Jan 2006

A Mathematical Model For The Validation Of Safe Air-Blast Chilling Of Cooked Hams, L. J. Wang, A Amézquita, Curtis L. Weller

Department of Agricultural and Biological Systems Engineering: Faculty Publications

An integrated mathematical model of heat transfer and temperature-dependent bacterial growth was developed to validate the safety of cooked hams during air-blast chilling. Heat transfer through a cooked ham was mathematically modeled and analyzed with a finite element method. Response of bacteria to temperatures was quantitatively described using predictive microbiology. The cumulative effect of temperature history on the bacterial growth was taken into account in the model. For chilling cooked hams from 71°C to 10°C, the maximum error between the predicted and experimental core temperature was within 2.2°C, and the deviation between the predicted and measured total weight losses was …

Feather Mites Are Positively Associated With Daily Survival In Cliff Swallows, Charles R. Brown, Kathleen R. Brazeal, Stephanie A. Strickler, Mary Bomberger Brown Jan 2006

Feather Mites Are Positively Associated With Daily Survival In Cliff Swallows, Charles R. Brown, Kathleen R. Brazeal, Stephanie A. Strickler, Mary Bomberger Brown

School of Biological Sciences: Faculty Publications

Feather mites (Acari: Astigmata) have been reported to be parasitic, commensal, and even mutualis-tic on the birds that serve as their hosts. We investigated whether there was a relationship between number of feather mites (Pteronyssoides obscurus (Berlese, 1885)) on the wing and daily survival of cliff swallows (Petrochelidon pyrrhonota (Vieillot, 1817)) during the breeding season at 12 nesting colonies in Nebraska in 2005. Survival of birds with known mite loads was monitored by mark–recapture, and survival models with and without a linear effect of mites were compared with the program MARK. For adult swallows, mites were positively associated …

Mechanomyographic Amplitude And Frequency Responses During Dynamic Muscle Actions: A Comprehensive Review, Travis W. Beck, Terry J. Housh, Joel T. Cramer, Joseph P. Weir, Glen O. Johnson, Jared W. Coburn, Moh H. Malek, Michelle Mielke Dec 2005

Mechanomyographic Amplitude And Frequency Responses During Dynamic Muscle Actions: A Comprehensive Review, Travis W. Beck, Terry J. Housh, Joel T. Cramer, Joseph P. Weir, Glen O. Johnson, Jared W. Coburn, Moh H. Malek, Michelle Mielke

Department of Nutrition and Health Sciences: Faculty Publications

The purpose of this review is to examine the literature that has investigated mechanomyographic (MMG) amplitude and frequency responses during dynamic muscle actions. To date, the majority of MMG research has focused on isometric muscle actions. Recent studies, however, have examined the MMG time and/or frequency domain responses during various types of dynamic activities, including dynamic constant external resistance (DCER) and isokinetic muscle actions, as well as cycle ergometry. Despite the potential influences of factors such as changes in muscle length and the thickness of the tissue between the muscle and the MMG sensor, there is convincing evidence that during …

The Future Of The Beef Industry, Gary C. Smith Dec 2005

The Future Of The Beef Industry, Gary C. Smith

Range Beef Cow Symposium

Weaber and Miller (2004) said “The structure of the cattle industry has changed dramatically over time, particularly in the packing and feeding segments. It’s a change driven by market dynamics that require participants to minimize production costs while at the same time, maintaining or improving quality. Producers that have met these two demands have remained in business through the various ‘boom or bust’ cycles in the beef industry.”

New Demands On Beef Products, Jim Coakley Dec 2005

New Demands On Beef Products, Jim Coakley

Range Beef Cow Symposium

The natural beef business is founded on the idea of providing food products that are an alternative to commonplace and are inherently high quality. A brand that is built on trust of the company and its suppliers to produce food products using specified raising practices that measure up to what the consumer desires and believes to be best for family and planet.
In 1989 the company wrote a mission statement that said:
By understanding our customers we will lead in the profitable marketing of natural and organic products using ecologically focused principles.

Management Strategies To Reduce Embryonic Loss, Tom Geary Dec 2005

Management Strategies To Reduce Embryonic Loss, Tom Geary

Range Beef Cow Symposium

Embryonic loss may represent the single greatest economic loss for cow/calf producers. With 40,000,000 beef cows and heifers exposed to breeding each year in the U.S., annual losses exceed $1.2 billion. The mechanisms involved in pregnancy establishment and maintenance are complex, and based on the literature, we have made little progress reducing embryo wastage in the past 90 years. This paper will focus on when and why pregnancy failures occur and discuss some management practices that may alleviate these losses.

In beef cattle, it is generally accepted that fertilization rates to a single service are between 90 and 100% regardless …

Supplementation, Winter Cow Nutrition, Don C. Adams Dec 2005

Supplementation, Winter Cow Nutrition, Don C. Adams

Range Beef Cow Symposium

It is generally accepted that protein supplements help beef cows efficiently utilize dormant forages and maintain body condition score (BCS) during fall-winter grazing. Additionally, protein supplements fed during fall and winter may impact subsequent cow reproductive performance and calf growth. Applications of supplementation in different extended grazing systems are presented.

Getting The Most Out Of A Vaccine Program, Charles L. Stoltenow Dec 2005

Getting The Most Out Of A Vaccine Program, Charles L. Stoltenow

Range Beef Cow Symposium

Vaccination programs have long been touted to be the answer to all your cattle disease problems. It isn’t that way. Vaccination is only one of many tools that producers and ranchers have at their disposal to try and manage an efficient and profitable operation. There are many other tools at their disposal.

When discussing vaccines, I have a favorite quote from Dr. Tim Richards at Kamuela, HI. He was the veterinarian for Parker ranch, the largest ranch in the United States. When Dr. Richards made that quote, Parker ranch was sending their feeder cattle by boat to the mainland for …

Key Indicators Of Success In Ranching: A Balanced Approach, Barry H. Dunn, Matthew Etheredge Dec 2005

Key Indicators Of Success In Ranching: A Balanced Approach, Barry H. Dunn, Matthew Etheredge

Range Beef Cow Symposium

While it has often been recognized that a ranch is greater than the sum of its parts, measuring and reporting the performance of the parts seems to be the common method of measuring the success of a ranch. Depending on the interest of the owner and manager, emphasis may be focused on cattle performance, or range management, or financial performance, or individual or personal accomplishments. Seldom does the discussion of success encompass some overarching measurement. The management tool known as “The Balanced Scorecard,” first developed by Robert S. Kaplin and David P. Norton in the early 1990s (Kaplin and Norton, …

Determining The Best Time To Wean, Steve Paisley, Kellie Chichester Dec 2005

Determining The Best Time To Wean, Steve Paisley, Kellie Chichester

Range Beef Cow Symposium

Production analysis and survey data suggests that the greatest contribution to annual cow production costs in the Northern Plains is harvested and purchased feed (Taylor and Field, 1995). Harvested hay is not only expensive to purchase, but it is expensive to put up and feed. Dunn (2002) showed that interest and depreciation on capital (required to handle hay) were major factors limiting profitability of ranching operations. Profit margins in cow/calf production are slim due to high production costs (Taylor and Field, 1995) and lost opportunity to capture value from marketable ranch products (NASS, 1999). Low input systems, or systems that …

A Producer’S Experience On Moving Calving Date, Mark H. Mccarty Dec 2005

A Producer’S Experience On Moving Calving Date, Mark H. Mccarty

Range Beef Cow Symposium

I grew up on a purebred operation, where we did everything the hard way. If it involved more labor, more overhead, and more inputs we did it that way. Calving season was of course the most labor intensive, coldest time of the year. We calved every cow through the barn and watched them around the clock. Each calf was weighed, tagged, vaccinated at birth, and not to mention probably nursed. Now we calve around 2,500 commercial cows and sometimes we check them, but most of the time we don’t even see the calves until branding time.

Effects Of Common Forage Phenolic Acids On Escherichia Coli O157:H7 Viability In Bovine Feces, J. E. Wells, E. D. Berry, V.H. Varel Dec 2005

Effects Of Common Forage Phenolic Acids On Escherichia Coli O157:H7 Viability In Bovine Feces, J. E. Wells, E. D. Berry, V.H. Varel

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

Ruminant animals are carriers of Escherichia coli O157:H7, and the transmission of E. coli O157:H7 from cattle to the environment and to humans is a concern. It is unclear if diet can influence the survivability of E. coliO157:H7 in the gastrointestinal system or in feces in the environment. Feces from cattle fed bromegrass hay or corn silage diets were inoculated with E. coliO157:H7, and the survival of this pathogen was analyzed. When animals consumed bromegrass hay for <1 month, viable E. coliO157:H7 was not recovered after 28 days postinoculation, but when animals consumed the diet for >1 month, E. coli …

Child Abuse And Neglect, David K. Dilillo, Michelle A. Fortier, Andrea R. Perry Nov 2005

Child Abuse And Neglect, David K. Dilillo, Michelle A. Fortier, Andrea R. Perry

Department of Psychology: Faculty Publications

Although all child abuse is disturbing, the story of Little Diana represents a particularly horrific example—one involving extreme cruelty that resulted the death of a young child. While death is not the most common consequence of abuse, it is the most tragic and unacceptable outcome. What can be gleaned from this case that might prove useful in preventing similar incidents of abuse in the future? In considering this question, two factors emerge that may shed light on important directions for child abuse advocacy. These factors center around the unique challenges faced by immigrant families, and the need for increased perpetrator …

Rapid Senescence In Pacific Salmon, Yolanda E. Morbey, Chad Brassil, Andrew P. Hendry Nov 2005

Rapid Senescence In Pacific Salmon, Yolanda E. Morbey, Chad Brassil, Andrew P. Hendry

School of Biological Sciences: Faculty Publications

Any useful evolutionary theory of senescence must be able to explain variation within and among natural populations and species. This requires a careful characterization of age-specific mortality rates in nature as well as the intrinsic and extrinsic factors that influence these rates. We perform this task for two populations of semelparous Pacific salmon. During the breeding season, estimated daily mortality rates increased from 0 to 0.2–0.5 (depending on the year) over the course of several weeks. Early-arriving individuals had a later onset and/or a lower rate of senescence in each breeding season, consistent with adaptive expectations based on temporal variation …

Safety Regulations For New Gmo Crops, Richard K. Perrin Oct 2005

Safety Regulations For New Gmo Crops, Richard K. Perrin

Cornhusker Economics

Starlink. Monarch Butterflies. Frankenfoods. These words conjure foreboding thoughts of potential catastrophe lurking behind the development of genetically modified organisms, or GMO’s. Are they really safe to be released? Are they safe to even experiment with? The purpose here is to describe the federal regulatory system that addresses these issues.

Corn Stalk Nitrate Concentration Profile, W. Wilhelm, G. E. Varvel, J. S. Schepers Oct 2005

Corn Stalk Nitrate Concentration Profile, W. Wilhelm, G. E. Varvel, J. S. Schepers

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

The end-of-season nitrate test provides a method of assessing the N available to the corn (Zea mays L.) crop during the latter part of the season. This study was conducted to determine how stalk nitrate test results and interpretations are affected by sample composition. Stalks were collected from three filed sites and separated into phytomers (node plus internode above), which were subdivided into three or five segments after length was measured. Nitrate-N concentration of phytomers decreased linearly from the soil to the ear. Within a phytomer, segments also decreased acropetally (from base to apex). Node tissue NO3-N …
