Lowering Somatic Cell Count With Best Management Practices, Stephen F. Higgins, Kylie Schmidt, Sarah Wightman

Agriculture and Natural Resources Publications

As health and food safety concerns grow, dairy producers are facing more stringent regulations. In 2010, the European Union (EU) set the somatic cell count (SCC) upper limit, an indicator of milk quality, for exported milk at 400,000 cells per milliliter. However, the current U.S. SCC limit is 750,000 cells per milliliter. As of January 2012, any U.S. milk used in export markets must meet the EU standards. It is projected that US milk processors will gradually adopt the EU upper limit, making it difficult for dairy producers to sell milk containing more than 400,000 somatic cells per milliliter. Dairy …

Residential Rain Gardens: Design, Construction, And Maintenance, Suzette Walling, Ashley Osborne, Brad Lee, Richard Durham

Agriculture and Natural Resources Publications

Stormwater runoff carries pollutants such as fertilizers, oil, animal waste, and dirt to local streams, lakes, and ponds and may contribute to flooding during heavy rainfall events, putting added stress on the receiving bodies of water and their ecosystems. Excess discharge impacts streams by causing erosion, destroying habitat, and deforming natural channel flow. Utilizing storage devices such as cisterns or rain barrels will minimize stormwater volume leaving your property. Contaminants discharged to streams can cause illness, impair ecological health, and increase water treatment costs.

An Ipm Scouting Guide For Common Problems Of Apple In Kentucky, Nicole Ward Gauthier, Ricardo Bessin, John Strang, Shawn Wright, Cheryl A. Kaiser

Agriculture and Natural Resources Publications

The National Integrated Pest Management Network defines IPM as “a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health, and environmental risks.” One of the key components of IPM is to continually scout and monitor crops to identify problems before they result in significant economic losses. Proper identification of pathogens and insect pests as well as nutritional and physiologic disorders and even herbicide drift is essential to determining the proper course of action. The pictures included in this guide represent some common pests or problems that growers may encounter …

Genome-Wide Analysis Of The Variation In Host Genetics In Response To Experimental Challenges With Porcine Circovirus 2b, Taylor B. Engle

Department of Animal Science: Dissertations, Theses, and Student Research

Porcine circovirus is the primary causative agent responsible for inducing a group of associated diseases known as porcine circovirus associated diseases (PCVAD), which can have detrimental effects on production efficiency as well as lead to mortality. The variation in host genetics plays a role in the ability to initiate an effective immune response. The objective of this research was to identify major genetic variants and genes that influence immune response and PCVAD susceptibility. Commercial crossbred pigs (n=974) were experimentally infected with a PCV2b strain to analyze genetic sources of variation in PCVAD susceptibility. The strain used for experimental infection was …

Should Ranchers Value Sagebrush? Why We Need Sagebrush, Beth Burritt, Thomas Monaco, Eric Thacker

All Current Publications

This fact sheet describes the value of sagebrush to ranchers. Big sagebrush is beneficial to grasses and forbs growing under its canopy by supplying them water, nutrients,organic matter and protection from overgrazing. It provides food and cover for a number of birds, reptiles, small mammals and beneficial insects. It can provide winter forage for both wildlife and livestock. Lastly, it is an important plant for revegetation efforts in the West.

Nutritional Value And Toxins In Various Noxious Weeds, Beth Burritt, Rae Ann Hart

All Current Publications

Teaching animals to eat noxious weeds may be a solution to reducing noxious weeds. Grazing animals often avoid eating weeds due to novelty even though weeds are often as nutritious as many of our planted pasture and rangelands species. This fact sheet provides livestock producers with the nutritive values of many common weeds. These values were summarized from a variety of peer-reviewed journal articles.

An Examination Of The Feasiblity Of A Food Hub For The Pee Dee Region, Emily Purcell

All Theses

Horry County, the home of Myrtle Beach, South Carolina, attracts a large level of spending by visitors who are helping to fuel growing demand for locally produced food. Regional growers are interested in meeting this demand but are limited by retail requirements with respect to lot size, timing, and quality (including food safety aspects such as Good Agricultural Practices (GAP) certification). A number of communities have turned to food hubs as a means of aggregating production by local growers and providing appropriate marketing functions, such as storage and meeting standards. Hence, food hubs can fill a gap between producers and …

Phenological Relationships Of Nesting Barn Swallows In A Swallow-Fly-Cattle System And Their Potential Role In Suppression Of Pest Flies In A Warming Climate, Claire Stuyck

All Theses

Conservation efforts for birds that provide ecosystem services in agricultural systems require management approaches that cross disciplines. This information is communicated through a variety of outlets but rarely in ways that interface effectively with normal management approaches. The disconnect between agriculture and wildlife conservation reduces the likelihood that ecosystem service benefits will be realized. One understudied ecosystem service provided by birds such as barn swallows (Hirundo rustica) is their role in suppression of flies that are pests to livestock. Climate change, however, may differentially affect flies that respond largely to temperature, and swallows that migrate and respond to photoperiod and …

Chemical Control Of Rootstock Regrowth In Grafted Watermelon And Its Effects On Plant Growth And Development, Shawna Daley

All Theses

High, year-round demand, increased production intensity without crop rotation, and the loss of Methyl Bromide as a soil fumigant, results in unfavorable soil conditions with increased soil pathogen populations for growing watermelon [Citrullus lanatus (Thunb) Matsum and Nakai]. Grafting watermelon onto resistant rootstocks provides successful control of soil-borne pathogens, and could increase yield and fruit quality; however, the high production costs, especially from labor, involved in grafted transplant production, has prevented the adoption of grafted watermelon use in the United States. Much of the labor is required for meristematic regrowth control, which can cause abortion of the scion and competition …

Physiological Impacts And Lactational Performance Of Dairy Cows Fed Brown Midrib Corn Silage During Dry Period Through Early To Midlactation, Alexandra Windley Kelley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Developing solutions to the metabolic stress experienced by cows during the transition period is very important because it can negatively influence lactational performance. The objectives were to: 1) compare physiological changes through body weight (BW) and concentrations of non-esterified fatty acids (NEFA) and β-hydroxybutyric acid (BHBA) and 2) evaluate feed intake, milk production, and energy balance (EB) of cows fed brown midrib corn silage (BMRCS)-based diets when compared with conventional corn silage (CCS)-based diets during the transition. At 4 wk prior to parturition, 40 dry multiparous Holstein cows …

Stacking Of A Stearoyl-Acp Thioesterase With A Dual-Silenced Palmitoyl-Acp Thioesterase And Δ12 Fatty Acid Desaturase In Transgenic Soybean, Hyunwoo Park, George L. Graef, Yixiang Xu, Patrick Tenopir, Thomas E. Clemente

Department of Agronomy and Horticulture: Faculty Publications

Soybean (Glycine max (L.) Merr) is valued for both its protein and oil, whose seed is composed of 40% and 20% of each component, respectively. Given its high percentage of polyunsaturated fatty acids, linoleic acid and linolenic acid, soybean oil oxidative stability is relatively poor. Historically food processors have employed a partial hydrogenation process to soybean oil as a means to improve both the oxidative stability and functionality in end-use applications. However, the hydrogenation process leads to the formation of trans-fats, which are associated with negative cardiovascular health. As a means to circumvent the need for the hydrogenation process, genetic …

A Content And Visual Analysis Of Promotional Pieces Used To Promote The Arkansas Soybean Promotion Board, Amy Hughes

Graduate Theses and Dissertations

A communications campaign was developed for a commodity promotion board in the southern region of the United States with promotional pieces produced and disseminated by a third-party communications group to reach the general public, soybean producers, and animal agriculture producers target audiences through key themes and messages. A systematic, content-driven approach assessed the potential impact on perceptions of individuals. This study utilized a content and visual analysis based on semiotic theory to analyze creative pieces and focus groups to assess content quality and impact.

Many of the creative pieces displayed too many themes, and the themes did not accurately represent …

Delay Of Bud Break On 'Edelweiss' Grapevines With Multiple Applications Of Amigo Oil And Naa, Benjamin A. Loseke

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

‘Edelweiss’ is an important grape cultivar grown in the Midwestern part of the USA. This grapevine is tolerant to extreme winter temperatures which can be experienced in the areas where it is most widely grown. ‘Edelweiss’ is one of the earliest cultivars in the vineyard to break bud, making it very susceptible to late spring freezes. The primary buds of ‘Edelweiss’ produce a significant amount of fruit, while unlike many other hybrids, the secondary and tertiary buds will have little to no yields, thus making it important to protect the primary buds from a late freeze. The objective of this …

Monitoring Citrus Nutrition In The Rio Grande Valley For Fertilizer Recommendations, Iram Lopez

Theses and Dissertations - UTB/UTPA

Soil fertility and plant nutrition is crucial for a better yield and consistent harvest in the Rio Grande Valley for local farmers growing citrus trees. A field of oranges and a field of grapefruits were monitored and nutrition deficiencies were noticed that played an important role during fruit set. Soil samples that were taken throughout the year were analyzed via a carbon dioxide extraction method that mimics the way plants naturally take up nutrients or extract nutrients from every soil type. Macronutrients such as the N, P, K, Na, Ca, Mg and some of the micronutrients (Zn, Fe, Mn, and …
