G1600 Freeze Concentration Of Fruit Juices, Durward Smith, Carol Ringenberg, Eric Olson

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes research conducted to examine the feasibility of freeze concentration with small-scale, simple equipment; and research results on juice extraction and concentration from fruit held in frozen storage.

When Grandmother made jelly the wonderful aroma of cooking fruit filled the house. That wonderful aroma was the delicate fruit flavors being evaporated and lost from the jelly. When volatile flavors are retained food has a much better flavor. Freeze concentration of fruit juices is a method of removing water from juices without heating and changing juice flavor. Freeze concentration is effective because a solute in solution has a lower …

Application Of The 1996 Nrc To Protein And Energy Nutrition Of Range Cattle, H. H. Patterson, D. C. Adams, T. J. Klopfenstein, G. P. Lardy

Department of Animal Science: Faculty Publications

Based on applications of the 1996 National Research Council (NRC) Nutrient Requirement of Beef Cattle (2000 update) model at our laboratories and on use of the model to evaluate published literature, it is our assessment that the NRC model (Level 1) represents an advancement in nutrient requirements of grazing cattle. We evaluated 8 published studies (35 treatment observations) to compare observed changes in body condition score (BCS) to those predicted by the NRC model, and to develop criteria to help with application of the model to range cattle nutrition. When in vitro organic matter disappearance (IVOMD) of grazed diets was …

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

The objectives of this study were to evaluate the accuracy of the Decision Evaluator for the Cattle Industry (DECI) and the Cornell Value Discovery System (CVDS) in predicting individual DMI and to assess the feasibility of using predicted DMI data in genetic evaluations of cattle. Observed individual animal data on the average daily DMI (OFI), ADG, and carcass measurements were obtained from postweaning records of 504 steers from 52 sires (502 with complete data). The experimental data and daily temperature and wind speed data were used as inputs to predict average daily feed DMI (kg) required (feed required; FR) for …

Contribution Of Postmortem Muscle Biochemistry To The Delivery Of Consistent Meat Quality With Particular Focus On The Calpain System, M. Koohmaraie, G. H. Geesink

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

Tenderness has been repeatedly reported as the most important quality aspect of meat. However, a number of studies have shown that a significant portion of retail meat can be considered tough. As a consequence, a significant consumer segment is willing to pay a premium for guaranteed tender meat. However, apart from measuring the shear force, there is no reliable method to predict tenderness. Most of the branded meat programs therefore attempt to ensure eating quality by controlling some of the factors that affect tenderness.

Meat tenderness is determined by the amount and solubility of connective tissue, sarcomere shortening during rigor …

Natural Abundance Of Foliar 15N As An Early Indicator Of Nitrogen Deficiency In Fertilized Cotton, S. Stamatiadis, C. Christofides, C. Tsadilas, V. Samaras, James S. Schepers

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

Information on the contribution of various soil nitrogen (N) sources to plant N uptake is often needed for the implementation of sustainable or site-specific management practices in agriculture. Considering the limitations of traditional methods in meeting these needs, this study investigated the potential of leaf δ¹⁵N as an early indicator of nutrient deficiency in cotton. The spatial and temporal natural abundance of ¹⁵N was measured in the soil and leaves of a fertilized cotton field located near the village of Moschochori (Larissa, Greece). The isotopic signal of the leaves was interpreted in the context of the relative …

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

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

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 …

Science-Based Organic Farming 2006: Toward Local And Secure Food Systems, Charles A. Francis, Katja Koehler-Cole, Twyla Hansen, Peter Skelton

Publications from the Center for Applied Rural Innovation (CARI)

Organic farming includes growing food and fiber—animals, agronomic crops, horticultural fruits and vegetables, related products—as one dynamic and rapidly evolving component of our complex U.S. food system. Even as more farmers are moving toward organic certification and participation in an environmentally sound and economically lucrative market, questions arise about the long-term social impacts and sustainability of a set of practices that has gone from a movement to an industry. Consolidations in the organic trade have brought multinational corporations to the table, as they have observed a grassroots activity that has grown by 20% per year for the past two decades, …

The Fathead Minnow In Aquatic Toxicology: Past, Present And Future, Gerald T. Ankley, Daniel L. Villeneuve

United States Environmental Protection Agency: Publications

This paper reviews the roles of the fathead minnow (Pimephales promelas) as a small fish model in the field of aquatic toxicology. The species has been (and is) extensively used both for regulatory testing and research, especially in North America. For example, tests with the fathead minnow, ranging from 48-h lethality through partial and full life-cycle assays, are routinely used for regulatory programs aimed at assessing potential risks of new chemicals such as high-production volume materials and pesticides, as well as impacts of complex mixtures like effluents. The species also has been used for a wide variety of …

Differential Expression Of Immune Response Genes In Steller Sea Lions (Eumetopias Jubatus): An Indicator Of Ecosystem Health?, Lizabeth Bowen, Brian Aldridge, Kimberlee Beckmen, Tom Gelatt, Lorrie Rea, Kathy Burek, Ken Pitcher, Jeffrey L. Stott

United States Department of Commerce: Staff Publications

Characterization of the polygenic and polymorphic features of the Steller sea lion major histocompatibility complex (MHC) provides an ideal window for evaluating immunologic vigor of the population and identifying emergence of new genotypes that reflect ecosystem pressures. MHC genotyping can be used to measure the potential immunologic vigor of a population. However, since ecosystem-induced changes to MHC genotype can be slow to emerge, measurement of differential expression of these genes can potentially provide real-time evidence of immunologic perturbations. MHC DRB genes were cloned and sequenced using peripheral blood mononuclear leukocytes derived from 10 Steller sea lions from southeast Alaska, Prince …

Continued Disappearance Of The Benthic Amphipod Diporeia Spp. In Lake Michigan: Is There Evidence For Food Limitation?, Thomas F. Nalepa, David L. Fanslow, Andrew J. Foley Iii, Gregory A. Lang, Brian J. Eadie, Michael A. Quigley

United States Department of Commerce: Staff Publications

Benthic surveys were conducted in the southern basin of Lake Michigan and throughout the lake to assess trends in benthic populations, emphasizing recent changes in densities of the benthic amphipod Diporeia spp. and dreissenid mussels. In the southern basin, Diporeia populations declined 89%, 91%, and 45% between 1993 and 2002 at sites <30, 31–50, and 51–90 m, respectively. Lakewide, the population declined 65% between 1994–1995 and 2000. Over the same time period, dreissenid densities, particularly Dreissena bugensis, increased. Intensive studies at 45 m sites in the southeastern region examined changes in lipid content, age structure, and benthic food inputs relative to the hypothesis that food limitation was a factor in Diporeia’s disappearance. As Diporeia densities declined to zero, length–weight remained unchanged, …

Miller, Rodger K. Johnson

Nebraska Swine Reports

This report is an annual update of an ongoing experiment initiated in 2005 to investigate effects of energy restriction during gilt development on reproduction through four parities. Gilts of two genetic lines expected to differ in rate of growth are used and are developed with either ad libitum access to feed or are restricted in energy to 75% of ad libitum amounts from approximately 120 days of age to breeding. Semen of the same sires, an industry maternal line, was used to produce gilts of both lines, but their dams were from two uniquely different populations. Dams of one line …

Effect Of Low-Protein Non-Amino Acid Supplemented Diet And Ractopamine (Paylean®) On Growth Performance And Serum Urea Concentration Of Late-Finishing Pigs, Roman Moreno, Robert Fischer, Phillip S. Miller

Nebraska Swine Reports

When feeding excessive amounts of protein, the nitrogen eliminated by the pigs in swine facilities has an important impact in the environment. Therefore, it is important to define nutritional strategies that promote a more efficient use of protein. This study was conducted to evaluate the effect of a low-protein non-amino acid supplemented diet and ractopamine (Paylean®) on performance of late-finishing pigs. Thirty-six finishing barrows and gilts with an initial body weight of 153.4 lb were used in a 42- day experiment. Pigs were penned individually and had ad libitum access to feed and water. The pigs were randomly allotted to …
