Consumer Opinions On Genetically Modified Food: A Community Discussion August 2005

University of Nebraska Public Policy Center: Publications

On Saturday, August 20, 2005, 48 residents of Lancaster County gathered at Gere Branch Library in Lincoln to participate in a “Citizen Deliberation on Genetically Modified Food.” A citizen deliberation is a technique used to promote informed and thoughtful public discussion on public affairs or policy issues and a means for gauging considered (as opposed to off-the-cuff) public opinions. The purpose of the discussion was to gauge informed public opinion on genetically modified food products and whether they should be labeled. The event was co-sponsored by the University of Nebraska Public Policy Center (http://www.ppc.nebraska.edu/edu/) and a local community leadership development …

Perspectives For Artificial Insemination And Genomics To Improve Global Swine Populations, Roger J. Gerrits, Joan K. Lunney, Lawrence A. Johnson, Vernon G. Pursel, Robert R. Kraeling, Gary A. Rohrer, John R. Dobrinsky

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Civilizations throughout the world continue to depend on pig meat as an important food source. Approximately 40% of the red meat consumed annually worldwide (94 million metric tons) is pig meat. Pig numbers (940 million) and consumption have increased consistent with the increasing world population (FAO 2002). In the past 50 years, research guided genetic selection and nutrition programs have had a major impact on improving carcass composition and efficiency of production in swine. The use of artificial insemination (AI) in Europe has also had a major impact on pig improvement in the past 35 years and more recently in …

Analyses Of Thermoregulatory Responses Of Feeder Cattle Exposed To Simulated Heat Waves, T. M. Brown-Brandl, R. A. Eigenberg, G. L. Hahn, J. A. Nienaber, T. L. Mader, D. E. Spiers, A. M. Parkhurst

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Heat stress in feedlot cattle causes reduced performance, and in the most severe cases, death of the animals, thus causing the loss of millions of dollars in revenue to the cattle industry. A study was designed to evaluate dynamics of thermoregulation and feeding activities when feeder cattle were exposed to simulated heat waves, in comparison with repeated sinusoidal hot and thermoneutral environments. Nine beef steers were randomly assigned to an individual pen in one of three environmental chambers. Each chamber was subjected to each of three temperature regimes (Heatwave simulation from Rockport, Mo., 1995, Heatwave simulation from Columbia, Mo., 1999, …

Effects Of Food Attributes And Feeding Environment On Acceptance, Consumption And Body Weight: Lessons Learned In A Twenty-Year Program Of Military Ration Research, Edward S. Hirsch, F. Matthew Kramer, Herbert L. Meiselman

United States Army: Publications

Twenty years of testing in the field has consistently revealed that food intake is inadequate when packaged military rations are fed as the sole source of food. Food intake is much lower and there is a loss of body weight. Conversely when these rations are fed to students or military personnel for periods ranging from 3 to 42 days in a cafeteria-like setting, food intake is comparable to levels of a control group provided with freshly prepared food. Under these conditions, body weight is maintained. In this review, the consumption pattern is considered in terms of characteristics of the food …

Chronic Wasting Disease Of Elk: Transmissibility To Humans Examined By Transgenic Mouse Models, Qingzhong Kong, Shenghai Huang, Wenquan Zou, Difernando Vanegas, Meiling Wang, Di Wu, Jue Yuan, Mengjie Zheng, Hua Bai, Huayun Deng, Ken Chen, Allen L. Jenny, Katherine I. O'Rourke, Ermais D. Belay, Lawrence B. Schonberger, Robert B. Pertersen, Man-Sun Sy, Shu G. Chen, Pierluigi Gambetti

Zoonotics and Wildlife Disease: Publications

Chronic wasting disease (CWD), a prion disease affecting free-ranging and captive cervids (deer and elk), is widespread in the United States and parts of Canada. The large cervid population, the popularity of venison consumption, and the apparent spread of the CWD epidemic are likely resulting in increased human exposure to CWD in the United States. Whether CWDis transmissible to humans, as has been shown for bovine spongiform encephalopathy (the prion disease of cattle), is unknown. We generated transgenic mice expressing the elk or human prion protein (PrP) in a PrP-null background. After intracerebral inoculation with elk CWD prion, two lines …

Folate Synthesis And Metabolism In Plants And Prospects For Biofortification, Gilles J. C. Basset, Eoin P. Quinlivan, Jesse F. Gregory Iii, Andrew D. Hanson

Center for Plant Science Innovation: Faculty Publications

Folates are essential cofactors for one-carbon transfer reactions in most living organisms and are required for the biosynthesis of nucleic acids, amino acids, and pantothenate. Unlike plants and microorganisms, humans cannot synthesize folates de novo and must acquire them from the diet, primarily from plant foods. However, lack of folates is the most common vitamin deficiency in the world and has serious health consequences, including increased risk of neural tube defects in infants, cancers, and vascular diseases. Consequently, there is much interest in engineering plants with enhanced folate content (biofortification). In this review, we outline progress in defining the plant …

Drought Preparedness Planning: Building Institutional Capacity, Donald A. Wilhite, Michael Hayes, Cody L. Knutson

National Drought Mitigation Center: Faculty Publications

Past attempts to manage drought and its impacts through a reactive, crisis management approach have been ineffective, poorly coordinated, and untimely, as illustrated by the hydro- illogical cycle in Figure 1. The crisis management approach has been followed in both developed and developing countries. Because of the ineffectiveness of this approach, greater interest has evolved in recent years in the adoption of a more proactive risk-based management approach in some countries (see Chapter 6). Other countries are striving to obtain a higher level of preparedness through development of national action programs that are part of the United Nations Convention to …

Crop Depredations By Cranes At Daursky State Biosphere Reserve, Siberia, Stephen H. Bouffard, John E. Cornely, Oleg A. Goroshko

Proceedings of the North American Crane Workshop

Crop depredations by staging cranes have been an annual problem at Daursky State Biosphere Reserve in southern Siberia. In September 2001 we met at Daursky when crane populations peaked to investigate the problem and suggest methods to reduce damages. Peak of crane staging coincided with grain harvest. We counted ≈ 30,000 cranes of 5 species, primarily demoiselles (Anthropoides virgo), in the area. Poor grain yields and cooperative farming systems discouraged efforts to reduce damage. Moving crops further from roost areas may be the most reasonable short term control method, but it’s effectiveness is yet untested. Hazing, lure crops …

Patterns Of Food Use Of Wintering Whooping Cranes On The Texas Coast, Craig M. Westwood, Felipe Chavez-Ramirez

Proceedings of the North American Crane Workshop

Whooping Crane (Grus americana) fecal samples were collected from Matagorda Island National Wildlife Refuge (MINWR) during winter and fall of 1993-94 (Winter-1; n = 59), and Aransas National Wildlife Refuge (ANWR) during winter and fall of 1993-94 (n = 102) and 1994-95 (Winter-2; n = 257) to study crane diets and compare patterns of food use in these areas. Food items varied between areas, across months, and between years in both frequency and percent volume. Blue crab (Callinectes sapidus), wolfberry fruit (Lycium carolinianum), horn snail (Cerithidea pliculasa), razor clam (Tagellus plebius), …

Evidence Of A Decline In Fat Storage By Midcontinental Sandhill Cranes In Nebraska During Spring: A Preliminary Assessment, Gary L. Krapua, David A. Brandt, Deborah A. Buhl, Gary W. Lingle

Proceedings of the North American Crane Workshop

When an ice storm killed an estimated 2,000 sandhill cranes (Grus canadensis) in the Central Platte River Valley (CPRV) in Nebraska on 24 March 1996, we retrieved the fresh carcasses of 118 adults to test for a decline in the condition of spring-staging cranes from that date in 1978 and 1979. We first conducted a principle component analysis on 3 morphological variables (tarsus, exposed culmen, and wing chord [flattened]) and used the first principal component (PC1) as an index of body size. Then, to account for variation in body mass due to size, we regressed body mass on …

Food Acceptability In Field Studies With Us Army Men And Women: Relationship With Food Intake And Food Choice After Repeated Exposures, Cees De Graaf, F. Matthew Kramer, Herbert L. Meiselman, Larry L. Lesher, Carol Baker-Fulco, Edward S. Hirsch, John Warber

United States Army: Publications

Laboratory data with single exposures showed that palatability has a positive relationship with food intake. The question addressed in this study is whether this relationship also holds over repeated exposures in non-laboratory contexts in more natural environments. The data were collected in four field studies, lasting 4–11 days with 307 US Army men and 119 Army women, and comprised 5791 main meals and 8831 snacks in total. Acceptability was rated on the nine point hedonic scale, and intake was registered in units of 1/4, 1/2, 3/4, or 1 or more times of the provided portion size. Correlation coefficients between individual …

Kant On Duties To Animals, Nelson T. Potter Jr.

Department of Philosophy: Faculty Publications

According to Kant we human beings are finite rational beings, who also have an animal nature. Kant occasionally speculates that perhaps on other planets there may be quite different sorts of finite rational animals. But of course we have no specific knowledge of any such. Given that fact, all of our duties are duties to other human beings. We can have no duties to God because he is not an object of possible experience. There are no human beings such that they have only duties and no rights--they would be slaves or serfs. And the apparent duties that we have …

Experimental Transmission Of Chronic Wasting Disease Agent From Mule Deer To Cattle By The Intracerebral Route, Amir N. Hamir, Robert A. Kunkle, Randall C. Cutlip, Janice M. Miller, Katherine I. O'Rourke, Elizabeth S. Williams, Michael W. Miller, Mick J. Stack, Melanie J. Chaplin, Jügen A. Richt

Zoonotics and Wildlife Disease: Publications

This communication reports final observations on experimental transmission of chronic wasting disease (CWD) from mule deer to cattle by the intracerebral route. Thirteen calves were inoculated intracerebrally with brain suspension from mule deer naturally affected with CWD. Three other calves were kept as uninoculated controls. The experiment was terminated 6 years after inoculation. During that time, abnormal prion protein (PrP^res) was demonstrated in the central nervous system (CNS) of 5 cattle by both immunohistochemistry and Western blot. However, microscopic lesions suggestive of spongiform encephalopathy (SE) in the brains of these PrP^res-positive animals were subtle in 3 …

Lake Whitefish And Diporeia Spp. In The Great Lakes: An Overview, Thomas F. Nalepa, Lloyd C. Mohr, Bryan A. Henderson, Charles P. Madenjian, Philip J. Schneeberger

United States Department of Commerce: Staff Publications

Because of growing concern in the Great Lakes over declines in abundance and growth of lake whitefish (Coregonus clupeaformis) and declines in abundance of the benthic amphipod Diporeia spp., a workshop was held to examine past and current trends, to explore trophic links, and to discuss the latest research results and needs. The workshop was divided into sessions on the status of populations in each of the lakes, bioenergetics and trophic dynamics, and exploitation and management. Abundance, growth, and condition of whitefish populations in Lakes Superior and Erie are stable and within the range of historical means, but …

Characteristics And Potential Causes Of Declining Diporeia Spp. Populations In Southern Lake Michigan And Saginaw Bay, Lake Huron, Thomas F. Nalepa, David L. Fanslow, Gretchen Messick

United States Department of Commerce: Staff Publications

Populations of the amphipods Diporeia spp. are declining in all of the Great Lakes except Lake Superior. We examine characteristics and potential causes of declines in southern Lake Michigan and outer Saginaw Bay, Lake Huron. Amphipod populations began to decline within 3-4 years after zebra mussels (Dreissena polymorpha) colonized both areas. In Lake Michigan, which was better studied, the decline occurred first in shallow waters (<30 m) and then progressed deeper (51-90 m). Between 1980- 1981 (pre-Dreissena) and 1998-1999 (post-Dreissena), densities at sites in these two depth intervals declined 92% and 58%, respectively. At a 45-m site in southeastern Lake Michigan, densities of Diporeia spp. …

Preliminary Investigations For Causes Of The Disappearance Of Diporeia Spp. From Lake Ontario, Ronald Dermott, Mohiuddin Munawar, Robert Bonnell, Silvina Carou, Heather Niblock, Thomas F. Nalepa, Gretchen Messick

United States Department of Commerce: Staff Publications

The amphipod Diporeia spp. comprised 60-80% of the benthos in offshore Lake Ontario and was an important food for fish. In eastern Lake Ontario, Diporeia spp. began disappearing in 1993 just after the arrival of dreissenid mussels. We compared survival of Diporeia spp. and Hyalella azteca in sediments from areas where Diporeia spp. populations had vanished with survival in sediments still inhabited. Survival was also examined in the presence of zebra mussel (Dreissena polymorpha) pseudofeces, filtered water from mussel cultures, and added bacteria. The Microtox® test indicated that sediment pore water was not toxic. Sediments from sites with …

University of Nebraska-Lincoln Extension: Historical Materials

Within the last 20 years, several meat-borne pathogenic microorganisms have emerged in the United States, causing numerous outbreaks of disease and death, as well as drastic economical losses.

Guidelines in this NebGuide are suggested for controlling temperature of meat and meat products in fabrication rooms so as to prevent detrimental growth of meat-borne pathogens.

Effect Of Increasing Dietary Crude Protein Concentration On Growth Performance And Serum Insulin-Like Growth Factor-I Concentration In Barrows And Gilts, Robert Fischer, Phillip S. Miller

Nebraska Swine Reports

A study was conducted to investigate the effects of increasing dietary protein intake on growth performance, carcass composition and serum insulin-like growth factor-I (IGF-I) concentration in growing-finishing barrows and gilts. Seventy crossbred pigs (35 barrows and 35 gilts) with an initial body weight of 75.1 lb were used in a 26-day growth study. The pigs were allocated randomly to one of four dietary treatments. The diets were standard corn soybean meal diets, which were formulated to contain 10, 14, 18, or 22% crude protein by changing the ratio of corn to soybean meal in the diet. At the termination of …

Development Of A Ncr-42 Vitamin-Trace Mineral Mix, Laura R. Albrecht, Robert L. Fischer, Phillip S. Miller

Nebraska Swine Reports

A vitamin-trace mineral mix (NCR-42 VTMM) and a vitamin B-safety pak (biotin, choline, folacin, thiamin and vitamin B₆) were formulated as possible common sources of nutrients for cooperative projects for the NCR-42 (North Central Regional) committee on swine nutrition. The adequacy of the NCR-42 VTMM and the vitamin B-safety pak were evaluated in a four-week growth trial with weanling pigs. The pigs (weaned 18-23d) were fed one of six diets: 1) NC, negative control, a common nursery diet with vitamins at minimum levels (VTMM OX); 2) treatment 1, a common nursery diet with VTMM vitamins at 100% of …

Symposium Paper: Economic And Tax Implications For Managing Beef Replacement Heifers, R. T. Clark, K. W. Creighton, H. H. Patterson, T. N. Barrett

Department of Agricultural Economics: Faculty Publications

Sustainable cowherds require replacement of cull cows either internally via raised heifers or externally with purchased females. Managing raised replacements begins with a weaned heifer calf and continues on through her second pregnancy and calving. Replacement costs were estimated from research conducted in Nebraska for spring-calving cowherds and included the opportunity cost of the heifer calf. The analysis, based on research data, showed that heifer development programs targeted to 50 to 55% of mature BW (MBW) at first breeding can be successful, challenging the traditional target of 65% of MBW at first breeding. The lower BW programs achieved …

G05-1583 How To Body Condition Score Dairy Animals, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

Routinely scoring the body condition of dairy animals can help detect potential problems that might cause a decrease in milk production.

As the production level of a herd increases, body condition scoring becomes more important. A routine program for body condition scoring can help detect potential health problems before they significantly reduce milk production. A herd of cattle in good body condition will produce more, and will be less susceptible to metabolic disorders, disease, mastitis and reproductive problems. Underconditioned cows are subject to health problems, and overconditioned cows are subject to calving difficulties, fatty liver syndrome and possible death.
