Transitioning To Net Energy: A Swine Story, John F. Patience
Proceedings of the Arkansas Nutrition Conference
Net energy (NE) is one member of the sequence of energy systems which also includes gross energy (GE), digestible energy (DE), and metabolizable energy (ME). It is perhaps the most sophisticated because it attempts to consider more components of the ingredient or diet which normally cannot be used by the pig for maintenance and/or productive purposes. Gross energy makes no such adjustment and therefore has little direct value in diet formulation. Digestible energy corrects for energy which is lost in the feces, and metabolizable energy also adjusts for energy lost in the urine. The data in Table …

Where Can We Go With Net Energy In Poultry?, Katie Hilton
Proceedings of the Arkansas Nutrition Conference
Metabolizable energy (ME) is the main system used globally in poultry industry for feed formulation and for evaluating feed ingredients and mixed feeds (de Boer and Bickel, 1988). ME is considered a reliable index of what is available to the bird for maintenance and production but is not a predictor of how efficiently the bird uses the available energy (MacLeod, 2000). The ME system developed by Hill and Anderson (1958) was reported to provide less variation in energy values for feed and ingredients than the Fraps PE system, but MacLeod (1994, 1997, 1999) suggest that the low variation …

Limestone Solubility: What Can You Do About It?, Wenting Li, Katie Hilton, Franco Mussini, Janet Remus
Proceedings of the Arkansas Nutrition Conference
Calcium (Ca) is essential for bone development mineralisation, as well as for eggshell formation, muscle and neural functions. Depending on the type of diets (veggie vs. non-veggie), species (turkey, chicken, duck), and age of animal (young vs. adult), limestone can contribute up to 95% total Ca in the final diet, with more Ca from limestone for younger animals with veggie diet. Despite the significant contribution of limestone to total diet Ca levels, the bioavailability variation of limestone Ca is rarely considered. Phosphorus (P) is a limited resource and is the third most costly ingredient in poultry …

Cell-Type-Specific Profiling Of The Arabidopsis Thaliana Membrane Protein-Encoding Genes, Sergio Alan Cervantes-Pérez, Marc Libault
Agronomy & Horticulture -- Faculty Publications
Membrane proteins work in large complexes to perceive and transduce external signals and to trigger a cellular response leading to the adaptation of the cells to their environment. Biochemical assays have been extensively used to reveal the interaction between membrane proteins. However, such analyses do not reveal the unique and complex composition of the membrane proteins of the different plant cell types. Here, we conducted a comprehensive analysis of the expression of Arabidopsis membrane proteins in the different cell types composing the root. Specifically, we analyzed the expression of genes encoding membrane proteins interacting in large complexes. We found that …

Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers
Aspen Bibliography
Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. As aspen ecosystems flourish or diminish, myriad dependent species follow suit. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers that are nutritiously desirable to browsing ungulates. Here, I evaluate aspen reproduction alongside numerous vital indicators of Pando's status in the first trend assessment of this embattled iconic forest. …

Evaluating Success Factors And Challenges Among Small-Scale Agricultural Producers: A Texas Case Study, Katie Tritsch, Ken Mix, Michelle L. Edwards, Manuel Piña Jr.
Journal of Rural Social Sciences
Literature on small farms in the U.S. is limited though they are the most numerous farm type, generate over twenty percent of agricultural production, and are more likely to be operated by historically underserved (i.e., beginning, minority, veteran, women, young) farmers than large-scale farms. This article details an online survey study of small-scale agricultural producers using a purposive sample from Texas. We used cross tabulations to evaluate qualitative operational and demographic (e.g., age, gender) factors of success, finding several significant variables with moderate effect sizes. Generally, producers regarded quality of life as more important to success than profitability. Producers’ top …

County-Level View Of Irrigation Trends In Utah And The West, Matt Yost, Britta L. Schumacher, Luree Johnson, Emily Burchfield, Burdette Barker
All Current Publications
We explored water use management and trends in irrigated agriculture in the U.S. West using operator-level USDA-NASS Farm and Ranch Irrigation Survey (FRIS)/Irrigation and Water Management Survey (IWMS) data aggregated for the first time to the county instead of state scale. Our hope is that this study will guide water managers in developing regional conservation programs, inform extension and research initiatives related to irrigation, promote grower-informed water conservation education, and provide researchers with key information regarding if, how, and why growers consider water conservation in irrigation decision-making.

Exploring The Impacts Of Lead Farmer Selection On Community Social Learning: The Case Of Farmer-To-Farmer Model: A Review Of Literature, Willis Ochieng, Colby J. Silvert, John Diaz
Journal of International Agricultural and Extension Education
Agricultural extension has shifted towards community-centric, farmer-centered, and participatory approaches that enhance rural change through a social learning lens, resulting in the emergence of the farmer-to-farmer extension model. The purpose of the study was to understand lead farmer selection criteria within the farmer-to-farmer model and their impacts on community social learning. We applied Torraco’s (2005) integrative literature review method to guide our discussion around lead farmer selection processes, types of lead farmers selected and their impacts on social learning. The study indicated farmer-to-farmer extension model has the potential of re-invigorating the provision of agriculture extension services owing to its low …
Vermicompost Versus Traditional Compost Amendments Leads To Different Soil Health Outcomes In A Mediterranean Vineyard,

California Polytechnic State University, San Luis Obispo
Vermicompost Versus Traditional Compost Amendments Leads To Different Soil Health Outcomes In A Mediterranean Vineyard, Elizabeth L. Luck
Master of Science in Environmental Sciences and Management Projects
Compost application has become a common practice in vineyard management to increase soil and crop health, however, the environmental externalities such as greenhouse gas emissions (GHG) from cropping systems that utilize organic fertilizers, such as compost, is uncertain. Vermicompost, which is compost created through the digestion of organic matter by earthworms, and its related ‘extract’ are commonly thought to provide more benefits for soil and crop health compared to standard compost. However, organic fertilizers such as vermicompost, vermicompost extract, and compost have not been compared in their effects on soil health in Mediterranean vineyards. In this two-year study, I assessed …

Arkansas Agricultural Experiment Station Research Series
While the basic growth and development of the cotton plant have not changed significantly in recent history, the business of cotton production is ever-changing. The last two years have seen us plant a crop just about as late as we thought possible, yet extended favorable conditions at season's end have been our salvation, helping to lead us to record yields. The economic environment over the last few years has been such that farmers need to produce record or near-record yields to advance. Unfortunately, production levels at the state yield average barely cover out-of-pocket expenses.
Great uncertainties exist for the upcoming …

University of Minnesota - Twin Cities
Butterhead Lettuce Variety Performance Trial In A Hydroponic Nft System, Leah Worth, Mary Rogers, Amanda Reardon
Midwest Vegetable Trial Reports
Lettuce (Lactuca sativa L.) is a cool-season crop grown exclusively for fresh consumption. The intensive consumer demand of pre-packaged and living butterheads in the market today has been supported by the shift of soil production methods to soilless hydroponic systems. Hydroponic varietal and fertility recommendations for living butterhead optimization are limited to small-scale growers, however. To increase understanding of butterhead lettuce fertility preference, we examined two different water reservoir fertility concentrations across 12 replicated nutrient film technique (NFT) systems planted with six butterhead lettuce varieties. No differences were found between varieties grown in either recommended or high fertility concentrations, …

Agronomy & Horticulture -- Faculty Publications
1. Rangelands of the United States provide ecosystem services that benefit society and rural economies. Native tree encroachment is often overlooked as a primary threat to rangelands due to the slow pace of tree cover expansion and the positive public perception of trees. Still, tree encroachment fragments these landscapes and reduces herbaceous production, thereby threatening habitat quality for grassland wildlife and the economic sustainability of animal agriculture.
2. Recent innovations in satellite remote sensing permit the tracking of tree encroachment and the corresponding impact on herbaceous production. We analysed tree cover change and herbaceous production across the western United States …

Crop variety selection is one of the most important choices on the farm. Crop genetics determine a significant portion of the yield potential and resource use efficiency. Crop types and genetics that use water more efficiently will become increasingly important as water becomes scarcer. Throughout Utah and the Western United States, water availability is decreasing due to various factors, including reduced snowpack and rapid urban growth. Alfalfa, other hay, small grains, and corn are grown on more acres than any other crops in Utah and much of the Intermountain West. These crops all have varieties, hybrids, and cultivars with the …
