Alfalfa Water Productivity And Yield Gaps In The U.S. Central Great Plains, Kaylin P. Fink, Patricio Grassini, Alexandre Rocateli, Leonardo M. Bastos, Jude Kastens, Luke P. Ryan, Xiaomao Lin, Andres Patrignani, Romulo P. Lollato

Department of Agronomy and Horticulture: Faculty Publications

Context: Yield gap (Yg) analyses using farmer-reported yield and management data have been performed for a number of annual grain crops, but it lacks for perennial forages. The U.S. accounts for 21 % of the global alfalfa production with a large rainfed area located in the central Great Plains, serving as an interesting case-study for Yg in perennial forages. Most existing alfalfa Yg analyses quantified the magnitude of the Yg but failed to identify associated management practices to reduce it. Challenging this analysis, a systematic benchmark for alfalfa water productivity [WP, kg dry matter per mm evapotranspiration (ETc)] that …

The Viability Of Traditional Portuguese Olive Groves In The Alentejo Region Under A Sustainable Development Framework, Sydney Soloway

Independent Study Project (ISP) Collection

Portugal became self-sufficient in olive oil production in 2014 and produces 150% of its needs, which makes Portugal the world’s fourth-largest exporter (DeAndreis, 2022). Olive groves in Portugal were once estimated to be 70-80% low-input traditional type, but rapid intensification toward a predominantly intensive mode of agriculture has been extremely fast (Beaufoy, 2001, p. 22; Silveira et al., 2018, p. 248). The Alentejo region, despite its dry Mediterranean climate and a tradition of extensive, multi-functional agricultural systems, is now home to 85% of Portugal’s olive groves and responsible for 77% of the country’s olive oil production (Dawson, 2019; Silveira et …

What Makes Mad Honey “Mad”? An Investigation Into The Obsession Of The Himalayan Wild Cliff Honey, Codi Farmer

Independent Study Project (ISP) Collection

Mad honey is a rare variety of cliff honey found in the mountainous regions of Turkey and Nepal and has been harvested by Indigenous groups for centuries. In Nepal, it is found on high-hanging cliffs that people risk their lives to face, but what makes this honey so special to cause generations of Nepalis to brave the formidable heights? Through a series of reading primary and secondary sources, watching first-hand accounts of honey hunting, and interviewing honey hunters, filmmakers, authors, and laypeople alike, I work to find the answer to the puzzling question – what makes mad honey "mad"? In …

Perennial Warm-Season Grass Forages Impact On Cow-Calf Profitability In The Fescue Belt, Kyle A. Brazil, Patrick D. Keyser, Andrew P. Griffith, Christopher N. Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

Incorporating a perennial warm- season grass (WSG) into tall fescue (Lolium arundina-ceum [Schreb.] Darbysh.) forage systems in the fescue belt can help avoid the effects of fescue toxicosis on beef cattle (Bos taurus) reproduction and animal performance and provide forage during summer when fescue production is low. However, little information is available on the economics of incorporating WSG into fescue-based forage systems. We developed a simulation model to compare profitability of three forage systems—100% tall fescue, 70% tall fescue/30% bermudagrass (Cynodon dactylon), and 70% tall fescue/ 30% switchgrass (Panicum virgatum)—while also comparing spring- …

There was a strict requirement of labeling application and its review process and clear label use regulations. The use value of labeling was publicized by online and offline media and cooperation with governments. Therefore, the standard management of the whole grain food labeling format, supervision of enterprises' use of labeling, publicity and education of the whole grain food labeling should be paid attention.

Ractopamine At The Center Of Decades-Long Scientific And Legal Disputes: A Lesson On Benefits, Safety Issues, And Conflicts, Kumail Abbas, Aqeel Raza, Ross D. Vasquez, Marri Jmelou M. Roldan, Nemi Malhotra, Jong-Chin Huang, Olivia Erin M. Buenafe, Kelvin H. -C Chen, Shin-Shin Liang, Chung-Der Hsiao

Chemistry Faculty Publications

Ractopamine (RAC) is a synthetic phenethanolamine, β–adrenergic agonist used as a feed additive to develop leanness and increase feed conversion efficiency in different farm animals. While RAC has been authorized as a feed additive for pigs and cattle in a limited number of countries, a great majority of jurisdictions, including the European Union (EU), China, Russia, and Taiwan, have banned its use on safety grounds. RAC has been under long scientific and political discussion as a controversial antibiotic as a feed additive. Here, we will present significant information on RAC regarding its application, detection methods, conflicts, and legal divisions that …

Engaging Farmers, Culinary Schools, And Communities In Value-Added Production To Strengthen Local Food Systems, Lauren B. Errickson, Ethan D. Schoolman, Virginia Quick, Sarah Davis, Anthony Capece

Journal of Extension

Value-added products can generate farm income and improve community food access, yet lack of available kitchen infrastructure and labor can limit farm production capacity. This project explored how community-based culinary schools might fill the gap. A unique “product share” model was identified and piloted, meeting the collective needs of farmers, a culinary school, and urban consumers. By researching farmer crop availability and business model preferences, and aligning value-added production with community food preferences, we demonstrate a successful pilot indicative that similar initiatives can be replicated in other metropolitan areas, with potential to engage cross-disciplinary extension professionals.

Setting The Stage For The Next Farm Bill Debate, Bradley D. Lubben

Cornhusker Economics

The 2018 Farm Bill is set to expire in September 2023. New farm bill legislation will be needed by then if authority is to be extended for a wide range of programs from farm support to conservation, nutrition assistance, credit, trade promotion, rural development, research and education, and more.

The agricultural committees in Congress have already held initial hearings and many agricultural and other interest groups have noted their policy priorities. However, formal debate on a new farm bill is not expected to begin in earnest until early 2023 when a new session of Congress convenes.

While the formal debate …

Are U.S. Consumers Willing To Pay More By The Lake? An Analysis Of Preferences For Great Lakes Region Fish, April Athnos, Simone Valle De Souza, Kwamena Quagrainie, Chinonso Etumnu, William Knudson, Ronald E. Kinnunen, Paul Hitchens

Department of Agricultural Economics Faculty Publications

U.S. per capita seafood consumption is historically high due to population and income growth and consumer preference shifts toward healthy protein options. Despite this expansion, U.S. fisheries, especially those in the Great Lakes region, no longer fulfill domestic demand due to pressure on fish stocks and regulatory constraints. Instead, aquaculture and imports fill the gap. Rainbow trout, yellow perch, and walleye—three species historically produced in the North Central Region (NCR)—exemplify such trends. To expand marketing opportunities for NCR aquaculture producers, this study estimates willingness to pay (WTP) for these species and several search and credence fish attributes. We designed and …

Broiler Vitamin Nutrition Guidelines, Nelson E. Ward

Proceedings of the Arkansas Nutrition Conference

In a time of record feed prices, nutritionists and production managers continue to look for opportunities to lower growout costs. Even though their contribution seldom exceeds 1-2% of feed costs, vitamins are not immune to this cost-crunching scrutiny. Furthermore, in late 2017, an unparalleled drop in global vitamin supply resulted in sharply increased prices, and in some cases, outright shortages. Such events have placed pressure on vitamin fortification levels in broiler feeds. Nutritionists decide on the fortification rates based on a variety of criteria – bird age, production phase, field experience, research trials, and so forth. The rapid change in …

Recent Findings On Phosphorus Digestibility Of Feed Ingredients In Broilers, Jay Hampton, Wenting Li, Franco Mussini, Katie Hilton, Janet Remus, Samuel J. Rochell

Proceedings of the Arkansas Nutrition Conference

Accurately meeting the dietary P needs of broilers is critical to ensure optimal bird performance, health, and welfare without causing undue environmental burdens associated with excess dietary P excretion. Phosphorus is commonly supplied in broiler diets from inorganic phosphates derived from non-renewable sources, but it has been estimated that peak P production will occur between 2030-2040 and that the global supply of P could be depleted within this century (Cordell and Drangert, 2009; Nest and Cordell, 2012). To address these concerns, inorganic P use in agriculture, including use in broiler diet formulation, requires careful stewardship. To this end, the dietary …

Proceedings of the Arkansas Nutrition Conference

A project was initiated to apply dietary CP reduction under commercial conditions. The main objective was to demonstrate and validate that dietary CP can be reduced without compromising broiler performance in a production system which is already rather efficient. In addition, we wanted to demonstrate the potential of dietary CP reduction on reducing N-excretions especially in the context of German revised regulations and monitoring attempts. Finally, as previous research suggested, few further aspects such as impact of dietary CP reduction on litter quality and quantity, footpad health, change of ingredient inclusion levels and related impact on sustainability impact factors were …

Application Of Simulation Modelling In Broiler Integration: Is It A Necessary Nutritional Tool?, Peter Chrystal

Proceedings of the Arkansas Nutrition Conference

Modelling techniques have been used in many industries globally to illustrate to others an understanding of the way processes work. Also, engineers and scientists employ models to predict the consequences of various courses of action. Simple pictorial models, such as the diagram of the chicken digestive system, are useful in education and may be more suitable than a photograph for the purposes of explaining how the animal converts ingested feed into components that can be assimilated, leaving residue that is excreted. Complex, predictive models seek to quantify a specified outcome based on defined inputs. Many attempts have been made over …

State Of The Art Pullet And Breeder Nutrition, Rick Van Emous

Proceedings of the Arkansas Nutrition Conference

During the last six to seven decades, broilers have been successfully selected for maximum growth and feed efficiency (Zuidhof et al., 2014). Modern fast-growing broilers reach a body weight of 2.0 to 2.5 kg in 35 to 45 days with an average daily growth of 55 or more gram a day (Augère-Granier, 2019). In a study with different broiler strains representative of broilers in 1957 or 1978 were compared with a broiler strain from 2005 (Zuidhof et al., 2014). The 2005 strain showed, over a 56-day growth period, a 4.6 times higher growth rate and a 50% lower feed conversion …

Broiler Breeder Males: Feed And Nutrition Discussion, Benton Hudson

Proceedings of the Arkansas Nutrition Conference

The methods for feeding broiler breeder males have evolved over recent decades, and further revisions will likely be needed as males become more challenging to manage. Since the introduction of separate male feeding systems in the early 1980’s, breeder males’ nutrient needs have been better managed via daily feed restriction. If a breeder operation can effectively produce, haul, and store a separate male diet, then it provides more options to use different nutrient levels or feed additives that are designed to enhance fertility. This article will outline the history of male-separate feeding and revisit nutritional research on fertility of broiler …

Amino Acids Were Not All Created Equal, Peter H. Selle, Shemil P. Macelline, Peter V. Chrystal, Sonia Y. Liu

Proceedings of the Arkansas Nutrition Conference

The contention that amino acids were not all created equal is based on the simple premise that intestinal uptakes of non-bound (synthetic, crystalline, feed-grade) amino acids are more rapid than their protein-bound counterparts. The post-enteral ramifications of this difference in bioequivalence are amplified in broiler chickens given their express growth rates and just one complication is the post-prandial oxidation of amino acids. The lack of bioequivalence between non-bound and protein-bound amino acids is a real obstacle to the development and adoption of reduced-crude protein diets that have the potential to promote sustainable chicken-meat production Thus, the purpose of this paper …

Recent Advancements On Calcium And Phosphorus Recommendations In Broilers, Justina Caldas, Marcelo Silva

Proceedings of the Arkansas Nutrition Conference

Calcium and phosphorus have been recognized essential nutrients in chickens since 1950’s (Lesson & Summers, 2001) playing important roles in bone development, among other functions. Calcium is assumed an inexpensive nutrient in animal least cost formulation while phosphorus is considered expensive and scant. The actual economic impact comes from the influence of calcium on phosphorus requirements, changes in phosphorus digestibility, buffer capacity, gut health, trace mineral absorption, fat digestibility, welfare traits, etc. Both minerals have important interactions to be considered during formulation. Few changes have been made over the past 20 years to calcium and phosphorus recommendations because these values …

Decoding The Gut Microbiome; Providing Solutions For Poultry Production, Nichoals Evans, Peter Karnezos, Curtis Novak, Diana Ayala, Emily Kimminau, Kay Russo

Proceedings of the Arkansas Nutrition Conference

The term “microbiome” refers to all the micro-organisms within a particular environment. In poultry, the microbiome is influenced by the barn, diet, and age of the birds and is believed to modulate immunity and inflammation. In the past, culture methods were primarily used to evaluate the presence of the various micro-organisms present in the microbiome; however, recent technological advances in genomic sequencing have revolutionized sample analysis. This technology has opened new avenues of research in poultry production and our understanding of the associated health challenges. Turkey cellulitis has been a major economic and health concern for many years. Traditional bacterial …

Application Of Nutritional Immunology In The Mitigation Of Economic And Production Losses In The Poultry Industry Associated With Food-Borne Pathogens, Coccidiosis, And Necrotic Enteritis., Shahna Fathima, Ramesh K. Selvaraj

Proceedings of the Arkansas Nutrition Conference

Sub-therapeutic doses of antibiotics were used in poultry production since the 1950s for improved production, prophylaxis, and animal welfare. Extensive and indiscriminatory use of antibiotics led to the emergence of antibiotic resistance in food-borne pathogens of public health significance (Jones & Ricke, 2003). As per the United States Centre for Disease Control, more than 2.8 million infections in 2019 were caused by multidrug resistant bacteria. Due to public health concerns, the use of antibiotic growth promoters in livestock production was prohibited by Sweden and Denmark in 1986 and 1998 respectively (Hammerum et al., 2007). The European Union banned the use …
