G96-1286 Porcine Reproductive And Respiratory Syndrome (Prrs) Virus, Angela Baysinger, V. L. Cooper

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains Porcine Reproductive and Respiratory Syndrome--its symptoms, transmission and diagnosis; and it discusses methods of prevention, management and control.

History

Porcine Reproductive and Respiratory Syndrome (PRRS) was first observed in 1986 in the United States and in 1990 in Europe. The syndrome was initially called Mystery Pig Disease in the United States since no known swine pathogens could be implicated. A number of titles have been used to describe this disease syndrome: swine infertility and respiratory syndrome (SIRS), porcine epidemic abortions and respiratory syndrome (PEARS), blue-eared pig disease as well as others. Since 1992, PRRS has been the …

G96-1292 Winter Care For Horses, Kathleen P. Anderson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses energy requirements, feeding alterations, water requirements, hair and hoof implications, and shelter needs for horses during winter.

As the weather turns cold, many horses are ridden less and less. It is easy to become relaxed in a horse's daily care since they are not being used as often. However, horses still require much care and attention throughout the winter. Often, even greater attention is needed since there are no green pastures to graze or ponds and creeks to drink from.

G96-1285 Dairy Health Management For Optimum Production And Reproductive Performance, Duane N. Rice, Rick J. Grant, Larry L. Larson

University of Nebraska-Lincoln Extension: Historical Materials

Maintaining a healthy herd is a constant challenge to today's dairy producer. This NebGuide suggests ways to increase and maintain the quality of your dairy herd. Maintaining a healthy herd is a constant challenge to today's dairy producer. Each year an average of 20 to 25 percent of dairy cows are culled due to poor reproductive performance or other health problems. Many factors influence the health and performance of a dairy herd. These include the entire scope of management factors from "on farm" activity to the associated business and financial interactions. All of these are controllable but require knowledge and …

Ec96-824 Dairy Economics In Nebraska: An Analysis Of Costs And Returns And Comparisons With Other States, H. Douglas Jose, Richard J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

Dairy Economics in Nebraska

The dairy sector is undergoing major structural changes and economic adjustments. The industry is also becoming more market oriented as government price supports decline. Increased competitiveness has kept milk prices relatively stable, but increased grain and other input costs in 1995-96 have put increased pressure on profit margins which were already narrow.

This publication is a compilation of data related to the current economics of dairy farming. The objective is to provide data to help dairy farmers make adjustments in their operations, such as expanding their herds, and to provide basic data for operators setting up …

Performance Of Vegetative Filter Strips With Varying Pollutant Source And Filter Strip Lengths, Puneet Srivastava, Dwayne R. Edwards, Tommy C. Daniel, Philip A. Moore Jr., Thomas A. Costello

Biosystems and Agricultural Engineering Faculty Publications

Vegetative filter strips (VFS) can reduce runoff losses of pollutants such as nitrogen (N) and phosphorus (P) from land areas treated with fertilizers. While VFS effectiveness is considered to depend on lengths of pollutant source and VFS areas, there is little experimental evidence of this dependence, particularly when the pollutant source is manure-treated pasture. This study assessed the effects of pollutant source area (fescue pasture treated with poultry litter) length and VFS (fescue pasture) length on VFS removal of nitrate N (NO₃-N), ammonia N (NH₃-N), total Kjeldahl N (TKN), ortho-P (PO₄-P), total P (TP), …

Vegetative Filter Strip Design For Grassed Areas Treated With Animal Manures, Dwayne R. Edwards, Tommy C. Daniel, Philip A. Moore Jr.

Biosystems and Agricultural Engineering Faculty Publications

Vegetative filter strips (VFS) are a low-cost management option that have been demonstrated to be effective in reducing runoff transport of fertilizer constituents applied to grassed areas (pasture or meadow). Runoff quality studies involving fertilizers applied to grassed areas suggest that VFS can be designed by assuming that (1) only infiltration is responsible for pollutant removal, (2) the first post-application runoff event is most important from a water quality perspective (enabling a design event approach), and (3) no pollutant build-up that degrades VFS performance will occur. The purpose of this study was to develop a VFS design algorithm for grassed …

Simulation Of Runoff Transport Of Animal Manure Constituents, Yang Wang, Dwayne R. Edwards, Tommy C. Daniel, H. Don Scott

Biosystems and Agricultural Engineering Faculty Publications

Runoff losses of land-applied animal manure constituents can adversely affect the quality of downstream waters. Reliable mathematical simulation models can help estimate runoff losses of animal manure constituents and identify management measures to reduce these losses. The objective of this study was to develop and calibrate an event-based simulation model to describe the runoff transport of solids (soil and manure particles) and nutrients (nitrogen and phosphorus) from areas treated with animal manure. The resulting model, consisting of linked hydrology, soil/manure transport, and nutrient transport components, is process-oriented and uses measurable parameters to the greatest degree possible. The three components of …

Quality Of Runoff From Four Northwest Arkansas Pasture Fields Treated With Organic And Inorganic Fertilizer, Dwayne R. Edwards, Tommy C. Daniel, John F. Murdoch, Philip A. Moore Jr.

Biosystems and Agricultural Engineering Faculty Publications

Long-term land application of animal manures, even at agronomic rates, can promote accumulation of soil phosphorus (P) which can, in turn, contribute to increased P loadings to downstream waters. The objective of this study was to assess the soil and runoff effects of replacing animal manure as a soil amendment with inorganic fertilizer (ammonium nitrate, NH₄NO₃) on fields that had been treated previously with animal manures. Runoff from two pairs of small fields (0.57 to 1.46 ha) was sampled from September 1991 to April 1994. All fields had been treated previously with animal manures; after runoff …

Poultry Litter-Treated Length Effects On Quality Of Runoff From Fescue Plots, Dwayne R. Edwards, Philip A. Moore Jr., Tommy C. Daniel, Puneet Srivastava

Biosystems and Agricultural Engineering Faculty Publications

Using experimental data and/or mathematical simulation models to identify practices that reduce pollution from manure-treated areas is sometimes perceived as limited by the unknown validity of extrapolating plot-scale data to larger areas and by uncertainties in modeling transport of various pollutants. The objectives of this study were to assess the effect of length of manure treatment on runoff concentrations of poultry litter constituents and to define the modes of transport (particulate versus soluble) for nitrogen (N), phosphorus (P), carbon (C), and solids. Poultry litter was applied to three 1.5- x 18.3-m fescue (Festuca arundinacea Schreb.) plots with runoff collection …

Application Of Simplified Phosphorus Transport Models To Pasture Fields In Northwest Arkansas, Dwayne R. Edwards, C. T. Haan, Andrew N. Sharpley, John F. Murdoch, Tommy C. Daniel, Philip A. Moore Jr.

Biosystems and Agricultural Engineering Faculty Publications

Runoff transport of phosphorus (P) is often predicted from simple equations with parameters determined from data applicable primarily to row-cropped and fallow cover conditions. The applicability, accuracy, and precision of such P transport prediction equations under pasture situations are less well defined. The objectives of this study were to determine parameters of simplified runoff P transport equations for pasture fields and to assess the accuracy and precision of the equations. Runoff, sediment yield, soluble P transport, and particulate P transport data were collected from four pasture fields in northwestern Arkansas. Runoff event enrichment ratios and extraction coefficients were computed, and …

Toolibin Catchment Revegetation Manual, Avril Baxter

Natural resources published reports

In1983, heavy winter rains resulted in severe inundation and flooding of the lower parts of the Toolibin catchment. The damage to crops and pastures was immense and costly. Local farmers realised that they needed to work together to minimise the impact of heavy rainfall events on their farm productivity.

At the same time the Western Australian Department of Conservation and Land Management (CALM) was concerned about the quality of both ground and surface water in the catchment area for Toolibin Lake, the last remaining wooded freshwater lake in the southern wheatbelt. This mutual interest led to the formation of the …

Investigations On Determination Of Nutritional Status Of Apricot (Cv. Hasanbey) Grown In Erzincan, Muharrem Güleryüz, İbrahim Bolat, Lütfi Pirlak, Ahmet Eşi̇tken, Sezai Erci̇şli̇

Turkish Journal of Agriculture and Forestry

This study was carried out to determine the seasonal variations in the amount of leaf nutrient elements, and nutritional status through soil and plant analysis in Erzincan apricot (cv. Hasanbey) orchards. The seasonal variations of plant nutrient element in leaves were generally minimum starting 20 days before harvest and lasted until harvest in Erzincan. This term was found the best time in order to collect the leaf samples At the experimental site pH ranged from 0.77 to 3.16%. Leaf N contents of some orchards were found to be below normal. P content of both soil and leaves was generally insufficient. …

Annual Forages: New Approaches For C-4 Forages, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

The current agricultural paradigm in the U.S. is heavily biased towards the production and marketing of crops as commodities. This paradigm is kept in place by grain handling and marketing infrastructure, as well as government farm programs, designed for crops as commodities. Sorghum (Sorghum bicolor L. Moench) and maize (Zea mays L.) grown for grain certainly fit into this current paradigm.

A new approach to agricultural production and marketing, identity preserved products, is gaining in importance. This is made possible through new technologies and markets demanding products designed specifically for their needs. Examples of investment in identity preserved …

Breeding Sorghum And Pearl Millet For Forage And Fuel, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Sorghum [Sorghum bicolor (L.) Moench] and pearl millet [Pennisetum glaucum (L.) R. Br.] are unique species in their ability to be used in many forage llivestock system roles. Such flexibility has made prioritizing breeding objectives difficult and has even contributed to contradictory opinions on appropriate forage breeding objectives. Few breeding projects identified in the USDA-ARS, USDA-CREES, or at ICRISAT had forage sorghum or forage pearl millet as their sole research assignment. In the United States, it can be argued that breeding resources committed to forage sorghum improvement are probably declining. A new forage sorghum and forage pearl millet …

Media Effects On Phenotype Of Callus Cultures Initiated From Photoperiod-Insensitive, Elite Inbred Sorghum Lines, H. F. Kaeppler, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Sorghum (Sorghum bicolor L. Moench) is a crop of worldwide agronomic importance. Routine production of high quality (friable, embryogenic, fast growing) callus cultures is fundamental to tissue culture based genetic study and improvement of sorghum. Genotype by culture medium interactions for sorghum callus growth and morphology have been previously reported. The objective of this study was to identify tissue culture media that would support high quality callus growth across photoperiod insensitive, relatively elite genotypes. Explants from immature inflorescences of 11 sorghum genotypes were cultured on 6 tissue culture media of differing composition. After 3 and 5 months in culture, calli …

Movement Of Crop Transgenes Into Wild Plants, Kathleen H. Keeler, Charles E. Turner, Margaret R. Bolick

School of Biological Sciences: Faculty Publications

Despite the great potential and increasing importance of other weed control options (Turner et al. 1992) and unwanted environmental side effects of some herbicides, herbicides constitute a very important means of weed control. The escape of herbicide resistance genes to wild, weedy plants could cause more severe weed problems, and presents a very real threat to the efficacy of herbicides as a weed control option. Therefore, management strategies that prevent, or reduce the likelihood and frequency of HRG escape through containment methods are advisable, as are mitigation plans in the event of HRG escape to wild plants.

Pilbara Steer Growth Evaluation : 1994 - 1996, Wayne Fletcher, Brian Mcintyre, Shane Cridland Dr, J L. James

Agriculture reports

Growth potential of steers in the Pilbara - a summary. The trial was conducted over a range of conditions on three locations. The pasture type at Wyloo, the Ashburton River frontage, which is regarded as one of the most productive pasture types in the area, combined with conservative stocking, a fresh paddock and excellent seasonal conditions during 1995, gives us an indication of the District's potential. In extrapolating any of these data to other cases, consideration must be given to adjustment base

Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller

Theses : Honours

The Bremer river catchment, on the South-coast of Western Australia, is typical of most river catchments in this region in that it has been seriously affected by sedimentation, salinisation and eutrophication brought on by the gradual dominance of agricultural land management practices. Vegetated rehabilitation and changed agricultural land management practices (ie minimum / zero tillage) have now been widely adopted throughout the catchment in response to these degradation issues. This study examined the potential impact minimum / zero tillage, vegetated rehabilitation and remnant vegetation could have on both a farm and catchment wide scale. A Geographical Information System was developed …

"Near-Organic" And "Mainstream" Crop-Livestock Production: South Dakota Case Study, Donald Taylor

Economics Research Reports (1969 - 2017)

In this report, results are presented of a case study on alternative strategies for producing crops and beef cattle in South Dakota. The alternative production strategies are termed "nearorganic" and "mainstream." "Near-organic" producers were defined as farmers/ranchers1 expected to substantially meet standards of private "organic" certification authorities in raising crops and livestock, whereas "mainstream" producers were defined as those who generally follow practices recommended by the S.D. Cooperative Extension Service. Four matching pairs of near-organic and mainstream case study farmers from the following locations were selected for study: Morristown in the Northwest Region, Norris in the South Central Region, Roscoe-Eureka …

Endangered Species And Irrigated Agriculture, Water Resource Competition In Western River Systems, United States Department Of Agriculture, Economic Research Service

Agriculture

This report characterizes several aspects of water allocation tradeoffs between fish species listed under the Federal Endangered Species Act and agriculture in the American West. The geographic intersection between endangered/threatened (E/T) fish and agricultural production reliant on surface water for irrigation is identified. Three findings are: (1) 235 counties, representing 22 percent of the West's counties, contain irrigated production that relies on water from rivers with E/T fish, (2) areas generating the highest revenues per acre from crop production are those most dependent on surface water irrigation, and (3) these same areas are also most likely to be drawing water …
