ABSTRACT

On the Ground•Natural solutions, such as “avoided conversion of grasslands,” offer agricultural land managers a way to mitigate climate change while monetizing climate benefits.•Managers who avoid converting grasslands to other uses, such as row crops, can quantify the amount of stored carbon and sell credits, but high costs of developing carbon credit projects price many landowners out of the carbon market.•Aggregation can create economies of scale, which lower barriers of entry and allow more landowners to participate in the market.•Given the current low prices in the carbon market, aggregation is not a panacea and aggregated projects are not financially viable for many landowners.•As the demand for carbon credits continues to grow, land managers can position themselves to take advantage of carbon market opportunities should prices increase, and projects become financially viable.

ABSTRACT

The Covid-19 pandemic has required implantation of online education strategies, even for animal science courses, that are traditionally delivered face-to-face (F2F). As universities reopened many students were given the option of attending classes either F2F or remotely via live stream. This scenario, where some students are present in-person while others are present online simultaneously, is referred to as hiflex teaching. Face-to-face and online teaching strategies are established and literature contains pedagogical information, however hiflex teaching presents previously unencountered challenges. It can be difficult for instructors to maintain engagement with, essentially, two separative audiences of students. The objective was to address this issue by providing a graduate teaching assistant (TA) to large lecture courses, where traditionally TA positions were reserved only for lab courses. The hypothesis was that this would enable both audiences to receive appropriate focus. In this study, a TA attended the F2F lecture for an introductory equine science course (total students: n = 75;remote students: n= ~55), with the role of monitoring the simultaneous Zoom session with remote students. We found that questions from remote students increased when they had the ability to post them in real-time using the Zoom chat feature, as opposed waiting for a break in instruction in F2F situations. Having the TA present in the classroom enabled them to answer basic questions via Zoom, and to interact with the instructor should a question arise online that would benefit all students in the course. This allowed the instructor to effectively teach without taking up valuable class time alternating between programs on the computer and risking missing an online student question. This approach received positive feedback from the instructor and students alike. Additionally, it provided a novel teaching experience for a graduate TA. Similar strategies may be used to help to facilitate future success in hiflex courses.

ABSTRACT

The objective is to present a strategy for attainment of capstone course objectives using design thinking. Problem based learning has long been incorporated into STEM, and yet inclusion of a formalized design thinking strategy is a novel approach for student-led cooperative learning. Relevancy of content and potential student impact upon the industry was established via the inclusion of stakeholders representing state livestock commodity groups who, via Zoom, met with students to present an overview of challenges facing their respective industries. Students, working in teams, used these conversations to formulate complex problems as the basis of their design thinking process. Subsequent steps of convergent and divergent thinking and low and high-fidelity prototyping led to creation of prototype solutions, which were continuously revised based upon feedback received after deployment. Solutions were prepared for dissemination to varied audiences using multiple communication strategies. Students were required to develop a technical report, scientific poster, infographic, narrated video, and oral presentation. The necessary buy-in from instructors, guest lecturers, students, and stakeholders is significant and a potential challenge to be addressed from the onset of the course. Further, use of design thinking typically requires students to transition from traditional course delivery and assessments to real world situations in which they receive process guidance, but must develop problem solutions themselves. Students required both prompting and restraint to follow the design thinking process. Frequent and transparent communication are helpful in ameliorating student frustration. The student group dynamic was heavily influenced due to covid-19, as teams contained a mix of students physically attending classes and those working remotely. Preliminary feedback suggests that all students engaging remotely via a Zoom meeting helps to create a more equitable and productive working environment. In its first iteration, students are engaged in design thinking and achieving capstone course objectives on schedule.

ABSTRACT

Beef Cattle Production & Management (ANSC 406) is a Texas A&M University “Communications” course and an elective in the undergraduate Animal Science curriculum. This course (3 hr lecture, 2 hr lab) is taught in Fall, Spring, and Summer semesters. The author has taught this (or equivalent) course since 1995, and various teaching technologies have incrementally crept into the course. Prior to COVID-19 restrictions, the class was taught traditionally through in-person lecture and lab meetings, with in-class, closed-note exams, and supported with online resources. Students are assigned to groups of 4 or 5 for semester-long work on a ranch management project with peer review comprising 20% of the grade. This report summarizes student exam grades and ranch project peer evaluations through semesters Fall 2019 to Fall 2020 where the class format was (1) traditional face-to-face (TF2F), (2) initially TF2F then switched abruptly to 100% remote/online, (3) 100% remote/online for the entire semester, and (4) a blended/hybrid format, respectively. Semester-to-semester exam grades and group member peer evaluations were compared through mixed model analyses of variance. There were no differences in exam grades (P > 0.10) across these semesters with the exception of Exam 3 that deviated 3.7% (P = 0.020) from lowest to highest mean scores. Relative exam grade variability (based on CV and range) remained almost constant from closed-book to open-note format. Remote vs. F2F status did not influence (P > 0.05) group peer evaluation scores regarding Q1: “Overall level of participation” or Q4: “Willingness to work for success of your group” when group number or student were included in statistical models. Model R-square values for Q1/Q4 increased from 0.037/0.050 to 0.161/0.171, and 0.424/0.457 when group, and student were added, respectively. Individual student perceptions and experiences appear to be major drivers of learning outcomes no matter the course delivery style.

ABSTRACT

Due to the recent COVID-19 pandemic, most of the universities across United States limited the amount of in person instruction. This brought a challenging situation in animal sciences courses that required laboratory sessions and hands-on experiences. There is not a real solution to replace the in-person labs, however several approaches can be implemented to overcome some of the challenges for laboratory sessions. Some of the on-line approaches implemented in an introductory class of Animal Sciences during the semester of spring and fall 2020 were live (synchronous) laboratory sessions (live interactions with animals, pre-recorded sessions of the laboratory session, and 360-degree videos of tours to the farms). The main objective of the present report is to assess the usefulness and feedback of these approaches to teach laboratory sessions to an undergraduate introductory animal science course. The official (Blue) university student responses in the course were used to determine the perception and feedback to these approaches. A total of 123 responses were recorded (Spring: 42/96, Fall: 81/174). Overall, no significant differences were observed in terms of the student perception. Overall, the responses were positive toward the laboratory sessions even in an online environment. During the spring semester 40/42 (95%), whereas in 72/81 (88%) strongly agree/mildly agree that labs help them to learn respectively. In terms of the videos used in class and labs, during the spring semester 35/41 (85%) and 68/81 (83%) strongly agree/mildly agree that labs help them to learn. In summary, the new reality due to COVID pandemic is very challenging for Animal Science courses that have laboratory sessions that involves hands-on experiences. Despite this, in conclusion some approaches can be implemented to still provide meaningful experiences to undergraduate students to support their learning and engagement in the introductory animal science course.

ABSTRACT

The global COVID-19 pandemic of 2020/2021 resulted in widespread impacts on the production & processing of animal proteins. Specifically, the U.S. pork industry was hit with multiple, long-term plant closures and slow-downs due to labor safety issues and availability, resulting in a backlog reaction felt throughout the live production supply-chain. Impact and timing differed by region and required variable strategies to address them. While some plants in the Western United States weren’t impacted until the latter stages of the pandemic and thus were attempting to add valuable liveweight, other regions, including the Midwest and Southeastern United States were experiencing moderate to severe reductions in processing capacity that created an accumulation of heavy animals and placed additional feed and ingredient demands on the feed mills. The backlog also reduced available space & disrupted the normal barn fill/empty cycles. While there was no way to prepare for these impacts, university & industry groups attempted to fill the knowledge gap with management and nutritional tools to address the issues of excess inventory, decreasing feed capacity, and supply-chain disruptions. Numerous approaches were employed, including altered grading strategies, sow breeding target reductions, double/triple stocking situations, and feed, ingredient, and nutrient manipulation meant to slow down growth rate and feed intake. Nutritional strategies included the feeding of low energy ingredients as well as low protein/high methionine diets designed to reduce the growth rate of both heavy and light animals. While several of these strategies resulted in moderate success, some resulted in additional issues including stress-related vices, ulcers, increased mortality, and sub-optimal carcass characteristics. Ultimately, continuous planning, coordination, and communication between the plants, feed mills, nutritionists, and production groups enabled a return to normalcy, and while we hope to never experience a pandemic again, we are left with knowledge that will improve the resilience of the U.S. pork industry.

ABSTRACT

Even though forage and grazing lands represent the largest land use in the United States, the number of forage faculty positions nationwide has decreased by 47% in the last 15 years, with only an estimated 2.3 forage research and Extension full-time equivalents (FTE) per state. This challenge has made partnerships with county/regional agents and Extension faculty from other states an increasingly important component of a successful Extension program. Whereas virtual/online programs existed prior to 2020, people of all ages are currently more comfortable and adept with virtual technology because of the COVID-19 pandemic. Moving forward, virtual meetings and hybrid meetings will likely become more routine, making it possible to disseminate knowledge to producers locally and across the state, region, and country concurrently. This approach will enable Extension educators to be more efficient in their knowledge transfer as illustrated by programs such as the Bermudagrass Hay Summit which has seen an almost six-fold increase in attendance from 2020 to 2021 because travel is not required. Lastly, there is a largely untapped opportunity in on-farm demonstrations and research. An example of how this can positively affect adoption of new technology is the regional program Alfalfa in the South. This program combines both on-farm and experiment station research. As a result of on-farm demonstrations, producer interest in adoption of alfalfa across Alabama and Georgia has increased in the last 3 years. There are many challenges to Extension programming in forages, but there are also ample opportunities to partner with other state Extension programs, as well as with producers to disseminate forage and pasture management effectively and efficiently to the forage and livestock sectors across the United States.

ABSTRACT

Beef is an abundant source of all proteinogenic amino acids (AAs;in both adequate amounts and balanced ratios) and physiologically essential nonproteinogenic AAs (taurine and β-alanine). The content and bioavailabilities of proteinogenic AAs in beef are greater than those in plant-sourced foods. Taurine (a potent anti-oxidant) is essential for the integrity and functions of tissues, including eyes, heart, and skeletal muscle, whereas β-alanine is required for the production of antioxidative and neuromodulatory dipeptides. Furthermore, beef contains a large amount of creatine (essential for energy metabolism in tissues, particularly brain and skeletal muscle), anti-oxidative dipeptides (carnosine and anserine), and 4-hydroxyproline (an anti-inflammatory nutrient that maintains intestinal integrity and inhibits colitis). There are myths that plants provide all nutrients that are available in animal-sourced foods. However, taurine, vitamin B12, creatine, carnosine, and anserine are absent from plants, whereas β-alanine and 4-hydroxyproline are low or negligible in plants. Like other animal-sourced foods, beef plays an important role in the optimum growth of children and the prevention of anemia in humans, as well as maintaining muscle mass, delaying ageing, and mitigating sarcopenia in adults, while meeting the high demands of exercising individuals for high-quality protein. Some epidemiological studies raised concern that the consumption of red meat might increase risks for chronic diseases in humans, including obesity, type 2 diabetes mellitus, cardiovascular disease, kidney disease, and cancers. However, findings from many epidemiological and clinical studies do not support these claims. Beef-derived AAs and other nutrients enhance the metabolism (e.g., nitric-oxide and glutathione syntheses) and the functions of monocytes, macrophages, lymphocytes, and other cells of the immune system, thereby helping the human host to kill pathogenic bacteria, fungi, parasites, and viruses. The latter include severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2 (COVID-19). Therefore, beef is a functional food for optimizing human growth, development, and health.

ABSTRACT

In August 2019, a fire at Tyson’s Finney County, Kansas, beef plant removed approximately 5% of U.S. beef packing capacity for 3 months. Subsequent COVID-19 pandemic-related precautions and workforce illness caused multiple packing plants across the country to decrease or stop production in the spring of 2020. Both events resulted in feedlots being unable to ship cattle at optimal finish points or according to projection. Estimates of the number of cattle backlogged during 2020 approach 1 million. Producers were faced with decisions on how to manage finished animals that could not be shipped while considering economic, animal welfare, and animal health outcomes. Many factors further complicated the situation including highly volatile markets, the possibility employee quarantine due to personal or family illness would cause operations to be under-staffed, and shortage of available pens for new cattle. Feeders had the option to slow the rate of growth of finished cattle due to the ability of ruminant animals to utilize low-energy feedstuffs or by calculating programmed rates of gain using the net energy system. Instead, many producers chose to attempt maximal rates of gain hoping persistent growth and feeding margins would offset discounts due to heavy carcass weights and excess fatness when the supply chain began moving again. Regarding new placements, the structure of the beef industry is uniquely developed to absorb cattle in stocker and backgrounding operations. This presentation will review the factors impacting cattle production and provide case-studies related to feeding at maintenance and growth rates, efficiencies, and carcass outcomes of held cattle from an operation and industry level.

ABSTRACT

Meat shortages in many of the largest retail chains during the early months of the COVID-19 pandemic affected millions of U.S. consumers. In addition, wait times for custom slaughter of meat animals increased from days to weeks to upwards of 14 mon. Interruptions in livestock slaughter and meat supplies have renewed the emphasis on medium, small, and very small meat slaughters/processors. Numerous states are investing in slaughter/processing plant construction, renovation of existing plants, and establishing or reestablishing state inspection programs. It is conceivable that this reinvestment may alleviate some of the meat supply limitations;yet, there are a number of factors these plants need to address for economic sustainability, including (but are not limited to): consistency of local and regional livestock supply;availability of trained, experienced workforce;plant holding pens and slaughter floor design;pre-slaughter animal welfare training and compliance;development and implementation of food safety programs;fresh and frozen storage capacities;local and regional marketing channels and modes of distribution;and by-products markets and offal disposal. Regardless of plant size, the ultimate goal of all meat packers/processors is the production of consistent, readily available and affordable, high-quality meat and meat products;however, the traditional driving forces of price and taste are being slowly supplanted by consumers’ concerns about production practices and animal management, perceived nutritional benefits, animal welfare concerns, food locality, and conveniences. This presentation will attempt to amalgamate the challenges facing medium, small, and very small meat processors with consumers’ preferences in relation to the sustainability of these revitalized segments of the livestock and meats industry.

ABSTRACT

Coronavirus Disease 2019 (COVID-19) was declared a global pandemic on March 11, 2020, by the World Health Organization. By April 2020, COVID-19 resulted in the simultaneous closure or reduced operations of many processing plants in the upper Midwest, which quickly resulted in supply chain disruptions. Iowa is the leading pork production and processing state, and these disruptions caused producer uncertainty, confusion, and stress, including time-sensitive challenges for maintaining animal care. The Resource Coordination Center (RCC) was quickly created and launched from the Iowa Department of Agriculture and Land Stewardship. The RCC had strategic collaborations with public representation from the Iowa Pork Producers Association, Iowa Pork Industry Center, and Iowa State University Extension and Outreach, and private partners through producers, veterinarians, and technical specialists. The RCC’s mission was four-fold: (1) implement appropriate actions to ensure the health and safety of RCC members, stakeholders, and the public, (2) evaluate and reassess appropriate actions as needed for continuity of pork production operations, (3) provide information to pork producers during supply chain disruptions, and (4) maintain a safe and abundant pork supply for consumers. The command structure included Incident Commanders, Command Staff, and four Section Chiefs whom worked with their respective experts. Sections covered (1) operations, (2) planning, (3) logistics, and (4) finance and administration. As it related to animal welfare, the RCC provided information on management decisions, dietary alterations to slow pig growth, pig movement to increase living space, alternative markets, on-farm euthanasia and mass depopulation. Veterinary oversight was continually maintained. A manual was created to provide up-to-date information to inform producer decisions and aid. Although originally created for swine, the RCC also assisted poultry, cattle and sheep producers. In a crisis, Iowa created a model that reacted to producer’s pragmatic and emotional needs. This model could be replicated for any emergency by other states.

ABSTRACT

The coronavirus (COVID-19) pandemic provided a unique insight into the impacts of global disasters on pet ownership and companion animal services. This talk will review research on the impacts of various stages of the pandemic on the human-animal relationship, surprising increases in the adoption of pets from animal shelters around the world, and the potential reasons for those increases. I will also present new research on the impact of the pandemic on pet support services within the city of Vancouver, Canada, that will highlight the complex relationships between vulnerable human populations, the city’s response to the pandemic, and pet care. Finally, the COVID-19 pandemic, and its associated economic impact, have completely re-shaped the field of animal sheltering and companion animal support services. In addition to being recognized as an essential service, animal shelter and veterinary staff were confronted with the need to identify only necessary operations to ensure care of animals and their communities without the risk of contracting and transmitting the virus. As a result, emergent animal sheltering trends now emphasize community-based approaches, abolishing harmful discriminative practices, and aiming to keep pets and their original owners together – all from the framework of One Health/ One Welfare. As global disasters are projected to increase in frequency due to climate change, a better understanding of impacts on the human-animal bond and support services will ensure that we can be better prepared for the future.
