Detecting Stress In Animals, Sharon Durham, Ted H. Elsasser

Agricultural Research Magazine

When people get stressed, they seek relief in many ways. Some exercise, some practice specific breathing techniques, and some eat chocolate. Farm animals become stressed, too. In domesticated food animals, stress can affect meat quality, milk production, and general health. But animal stress must often be intuited from clues such as lower-than-anticipated weights and increased illness.

Certain stressful events can be anticipated, for example, birth and weaning. But how do you know if an animal is stressed for some other reason? Ted H. Elsasser of ARS’ Growth Biology Laboratory in Beltsville, Maryland, is investigating nitrated protein as a biomarker of …

Speeding Up Breeding Of Superior Plants, Judy St. John

Agricultural Research Magazine

That oatmeal you ate for breakfast this morning is loaded with healthful compounds known as antioxidants. They help to protect your body from damage caused by molecules known as free radicals. Oats, for instance, are rich in the antioxidants alpha-tocopherol and alpha-tocotrienol.

But what if tomorrow’s oats could provide even more of these health-imparting compounds? That’s a goal of ARS oat researchers at laboratories in several states. Aiding this research is an invaluable tool of modern biotechnology. Known as biomolecular markers, gene markers, or DNA markers, these pieces of genetic material are signposts or clues. They are telltale indicators that, …

G02-1445 Understanding Vaccines, Dicky D. Griffin, Steve Ensley, David R. Smith, Grant Dewell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains the basics of vaccine value, the differences between types of vaccines used in animals, and discusses vaccine selection and vaccination program development.

Vaccines are an important part of disease prevention and control. Like insurance, vaccines come at a cost, including the price of the vaccine, labor to administer the vaccine, localized tissue damage from vaccine injections, and increased metabolic demand of the animal causing potential performance loss during the time the animal is developing a proper immune response. The increased metabolic demand can cause the animal to look depressed and therefore may be confused with illness. This …

Ec02-173 Spotted And Diffuse Knapweed, Neil L. Heckman, Ryan M. Goss, Roch E. Gaussoin, Stevan Z. Knezevic, John L. Lindquist

University of Nebraska-Lincoln Extension: Historical Materials

Spotted knapweed (Centaure amaculosa Lam. = C. biebersteinii DC.) and diffuse knapweed (C.diffusa Lam.) are two of Nebraska’s seven noxious weeds. They are also noxious in at least 17 other states. These are closely related species that are well adapted to a variety of habitats including open forests, rangelands and pastures, Conservation Reserve Program lands, roadsides, and ditch banks. Centaurea is a large genus of over 400 species, 32 of which are common weeds of the United States and several of which [e.g., yellowstar thistle, C. solstitalis L, and Russian knapweed, C. repens L. =Acroptilon repens (L.) …

G02-1476 Prairie Dogs And Their Control, Scott E. Hygnstrom, Dallas Virchow, John Hobbs

University of Nebraska-Lincoln Extension: Historical Materials

Black-tailed prairie dogs are stocky, burrowing rodents that are members of the squirrel family. They are the only species of prairie dog native to Nebraska and they live across the western three-fourths of the state. They cause problems, however, when they conflict with livestock ranching and other land uses, or cause a threat to human health and safety.

This NebGuide provides information on the life history and legal status of black-tailed prairie dogs and prevention and control of the damage they can cause.

G02-1482 Guidelines For A Non-Fasting Feeding Program For The Molting Of Laying Hens, Sheila E. Scheideler, Mary M. Beck

University of Nebraska-Lincoln Extension: Historical Materials

Laying hens are molted at the end of one laying cycle (i.e. one year) to induce a cessation of lay and rejuvenation of the reproductive tract and skeleton for a second cycle of egg production. This is based on the natural molting process that wild birds undergo annually and traditionally it has been induced by fasting the hens for a short period of time. This NebGuide offers guidance on non-fasting feeding program for the molting of laying hens.

Analysis Of Consumer Perceptions Toward Biotechnology And Their Preferences For Biotech Food Labels, St. Everald A. Mclennon

LSU Master's Theses

Using a sample from the seven largest metropolitan areas in the United States, (Denver, Chicago, Los Angeles, Atlanta, New Orleans, New York, and Houston), consumer attitudes concerning agricultural biotechnology is examined. Conjoint analysis is used to examine consumer preferences for the labeling of biotech foods. The study examines the relationship between the consumer’s knowledge and attitudes regarding biotech foods and their preferences for food labels. Consumers’ attitudes regarding a healthy diet, and their risk perceptions regarding biotech foods were found to have a significant effect on the general use of food labels and preferences for labeling of biotech foods. The …

Factors Affecting The Selection Of Business Arrangements By Hog Producers In The United States, Christopher Gazzara Davis

LSU Doctoral Dissertations

The structure of the U.S. hog industry is changing rapidly. U.S. hog farms have become smaller in number, larger in size and more specialized. This study examines the factors that influence the hog producer's choice among business arrangements offered in the U.S. hog industry. A national survey was mailed to 4,986 hog producers to determine these factors. The survey consisted of questions covering topics such as: production characteristics, autonomy, transaction costs, risk, social relationships, and demographics. A response rate of 21% was received from the mailed surveys. Four alternative business arrangements were used: independent production, cooperative farming, flat-fee contract, and …

Botrytis In Wine Grapes In Western Australia, Diana Fisher, Colin Gordon, Peter Wood

Bulletins 4000 -

Botrytis, causal agent Botrytis cinerea, is a fungal disease of grapevines that is commonly referred to as Botrytis bunch rot or grey mould. Botrytis is most prevalent where warm, wet conditions are frequent, but symptoms can occur in cool, wet weather and high humidity. All grape varieties are susceptible. Varieties most at risk are those with berries that are thin-skinned and/or have tight bunches.

Some white wine grape varieties infected with Botrytis may decay, in certain conditions to produce noble rot . Wine produced from these infected bunches produce unique aromatic characters with high residual sugar and are …

Organic Beef A Production Guide, Steven Mccoy

Bulletins 4000 -

Premium markets are expanding worldwide for certified organic and biodynamic beef products – those grown in accordance with recognised organic production and processing standards.

Many agricultural areas in Australia have the potential to produce organic beef, and several Western Australian and Eastern States organic producers are already exporting to Japan. Supermarkets such as Coles and Woolworths have started to build the Australian domestic market.

Converting to an organic system can be easier - requiring fewer changes - in ‘low input’ rangeland cattle production than in more intensive pasture-based or feedlot production. But regardless of the type of enterprise, managing organic …

Genetic Analysis Of Feed Quality And Seed Weight Of Sorghum Inbred Lines And Hybrids Using Analytical Methods And Nirs, C. Hicks, M. R. Tuinstra, Jeffrey F. Pedersen, F. E. Dowell, K. D. Kofoid

Department of Agronomy and Horticulture: Faculty Publications

Eight lines of grain sorghum and their F1 hybrids were evaluated for contents of crude protein (CP), fat (FAT), and starch (STA); protein digestibility (PD); and in vitro dry matter disappearance (IVDMD). The effect of seed weight (SW) on these traits and the potential use of near infrared reflectance spectroscopy (NIRS) to predict them also were investigated. The male lines included three normal-seeded lines (TX2737, TX435, and P954063) and two largeseeded lines (PL-1 and Eastin1). The female lines included commonU.S. seed parent lines (Wheatland, Redlan, and SA3042). The lines and their hybrids were grown under dryland conditions at Kansas State …

Combinatorial Control Of Yeast Fet4 Gene Expression By Iron, Zinc, And Oxygen, Brian M. Waters, David J. Eide

Department of Agronomy and Horticulture: Faculty Publications

Acquisition of metals such as iron, copper, and zinc by the yeast Saccharomyces cerevisiae is tightly regulated. High affinity uptake systems are induced under metal-limiting conditions to maintain an adequate supply of these essential nutrients. Low affinity uptake systems function when their substrates are in greater supply. The FET₄ gene encodes a low affinity iron and copper uptake transporter. FET₄ expression is regulated by several environmental factors. In this report, we describe the molecular mechanisms underlying this regulation. First, we found that FET₄ expression is induced in iron-limited cells by the Aft1 iron-responsive transcriptional activator. Second, FET …
