More Than Fiber: Forage Carbohydrates Affecting Animal Performance, M. B. Hall

IGC Proceedings (1977-2023)

Forages are well known as an important source of fiber in livestock diets. However, their carbohydrate contribution is more than fiber. Forage grasses and legumes supply sugars, fructans, and other water-soluble carbohydrates as well as soluble fiber that behave very differently than starch in the rumen. With a focus on ruminants, we will explore the forage supply, and ruminal and animal impacts.

Extending The Grazing Season Through The Use Of Cover Crops, D. D. Harmon

IGC Proceedings (1977-2023)

The use of cover crops in integrated crop-livestock systems is not a novel approach but has increased in popularity over the last few years due to the renewed interest in soil conservation, nutrient cycling, and water conservation. Moreover, cool-season annual forages have the ability to extend the grazing season, reduce the need for stored or bought supplemental feedstuffs, and as a result, lower winter-feeding costs. Small grain cover crops, legumes, forbes, and annual ryegrass (Lolium multiflorum Lam.) vary in their growth distribution and can be planted alone in monocultures or planted in mixtures to take advantage of the individual …

In Vitro Methane Production From Heifers Offered Four Bermudagrass Cultivars, A. R. Hines, W. G. Bergen, M. K. Mullenix, S. L. Dillard, T. R. Callaway, W. B. Smith

IGC Proceedings (1977-2023)

Though bermudagrass (Cynodon dactylon [L.] Pers.) is one of the predominant warm-season perennial forage supporting the southeastern United States livestock production systems, little is known about its influence on parameters of ruminal metabolism, including carbon loss as methane. With the multitude of cultivars of this grass that have been developed and released, one may question whether the physiological cultivar differences will manifest varying results in digestive efficiency and subsequent methane emissions. Thus, the objective of this study was to evaluate in vitro methane (CH4) production as influenced by four bermudagrass cultivars. Ruminally-fistulated heifers (n = 4) were assigned randomly …

Adoption Of Plantain Within New Zealand Farming Systems, Michael B. Dodd, J. B. Pinxterhuis, P. Hedley, L. Keenan, A. Duker, A. Moorhead

IGC Proceedings (1977-2023)

In New Zealand, plantain has been incorporated into the pasture forage base in three ways: as a short-term pure crop; as a major component in “herb mixes” that include clovers and chicory; and as a minor component in perennial grass-based swards. All types are typically grazed in-situ. Given the incentive to optimise the plantain proportion in livestock diet to mitigate nitrogen losses and the observed lack of persistence in grass-dominant pasture over time, there is a need to use various pasture types strategically across a farm system to ensure a long-term sustainable contribution of plantain to feed intake. The inclusion …

A Multicriteria Assessment Of Forage Or Concentrate-Based Finishing Diets For Temperate Pasture-Based Suckler Beef Production Systems, P. R. Doyle, Edward G. O’Riordan, Mark Mcgee, Paul Crosson, A. K. Kelly, A. P. Moloney

IGC Proceedings (1977-2023)

This study evaluated the effect of contrasting ‘finishing’ diets on animal performance, meat nutritional value, land use, food-feed competition, farm economics and greenhouse gas (GHG) emissions in temperate pasture-based suckler weanling-to-steer beef systems. Post-weaning, eight-month-old, spring-born, late-maturing breed steers (333 kg) were assigned to one of three systems: (1) Grass silage + 1.2 kg concentrate DM (148 days), followed by pasture (123 days) and finished on ad libitum concentrates (120 days) - slaughter age, 21 months (GRAIN); (2) as per (1) but pasture (196 days) and finished on grass silage ad libitum + 3.5 kg concentrate DM (124 days) - …

Nutrient Cycling And Crop Responses On Integrated Crop-Livestock Systems, José C. B. Dubeux Jr., E. R. S. Santos, J. E. Portuguez-Acuna, L. M. D. Queiroz

IGC Proceedings (1977-2023)

Integrated crop-livestock systems (ICLS) can bring numerous benefits to crops or livestock systems, such as increase soil C sequestration, farm profitability, and provisioning of ecosystem services. In a changing world, production systems need to become more resilient and sustainable. Specialized agriculture is characterized by a high level of inputs and outputs, and oftentimes specialize in a single crop to simplify management. However, such operational systems stray away from sustainable standards. Furthermore, specialized cropping systems may face problems such as persistence of pests and diseases, loss of biodiversity, stagnant yields, development of herbicide-resistant weeds, soil erosion and consequently loss of soil …

Forage Brassica Use In New Zealand And Australia Farming Systems, A. Dumbleton, H. G. Judson

IGC Proceedings (1977-2023)

Forage brassica, genus Brassica, are annual feed crops grown on farming enterprises throughout New Zealand and Australia. These crops provide a source of high-yielding, high-quality feed, which is particularly useful to complement pasture production during periods when pasture growth is reduced. There are six forage brassica species and subspecies of agricultural importance including bulb turnip, swede, kale, forage rape, leafy turnip, and raphanobrassica. All of these, as well as interspecific crosses and individual cultivars, offer a range of characteristics to fit various environmental and livestock production challenges. Consumption of forage brassica crops in ruminant animals may reduce methane emissions …

Wildland Resources Faculty Publications

We evaluated the relationship between individual and herd GIN infection level, nutrition, production performance and anemia parameters in a tropical farm context. Fifty-four female goats were monitored to assess their body condition score (BCS, nutritional status indicator), live weight (LW) and LW gain (LWG, both used as production level indicators), FAMACHA© and hematocrit (HT, both used as anemia indicators). Goats browsed for 4 h in a tropical forest and received balanced feed and chopped grass. The eggs per gram of feces (EPG) indicated the GIN burden, with fecal samples obtained at 7:00 (AM) and 15:00 h (PM.) from each goat …

The field of developmental biology has declined in prominence in recent decades, with off-shoots from the field becoming more fashionable and highly funded. This has created inequity in discovery and opportunity, partly due to the perception that the field is antiquated or not cutting edge. A 'think tank' of scientists from multiple developmental biology-related disciplines came together to define specific challenges in the field that may have inhibited innovation, and to provide tangible solutions to some of the issues facing developmental biology. The community suggestions include a call to the community to help 'rebrand' the field, alongside proposals for additional …

Dantas, R. Caitlin Hebert, Ma Kayla Tanksley, Robbie A. Beyl, Edward C. Mader, John P. Kirwan, Christopher L. Axelrod, Prachi Singh

School of Medicine Faculty Publications

Obstructive sleep apnea (OSA) is associated with increased risk for diabetes, and standard treatment with positive airway pressure (PAP) device shows inconsistent effects on glucose metabolism. Metformin is known to treat and prevent diabetes, but its effects on skeletal muscle mitochondrial function are not completely understood. Here, we evaluate the effects of metformin on glucose metabolism and skeletal muscle mitochondrial function in patients with OSA. Sixteen adults with obesity (50.9 ± 6.7 years, BMI: 36.5 ± 2.9 kg/m2) and moderate-to-severe OSA were provided with PAP treatment and randomized to 3 months of placebo (n = 8) or metformin (n = …

Food Labeling: Ingredient Exemptions And Product Claims, Elena Krasovkaia, Bradley J. Rickard, Brenna Ellison, Brandon R. Mcfadden, Norbert Wilson

Agricultural Economics and Agribusiness Faculty Publications and Presentations

New breeding methods have provided scientists with opportunities to improve traits in a wide range of crops, however, there remains resistance to foods that are produced from these crops, and mandates on labels used to describe such processes continue to be a source of policy debate. Here we focus on gene editing and examine (i) whether consumer acceptance varies when the technology is applied to different ingredients (unrefined versus highly refined ingredients) and (ii) the impact of two different claims related to gene editing (health-focused claim versus an environment-focused claim). Our results show that consumers are less likely to purchase …

Mindfulness Resources In The Academic Library, Rebecca Maynite, Beryl White-Bing, Lauren Odom, Robin Mcneil

Library Faculty Presentations & Publications

Listeners describe "tingles" as the ASMR experience, but many others enjoy ASMR even if they don't get tingles. ASMR videos have grown in popularity over the years. Recently, they made a resurgence on TikTok, even in parody form (think of the viral Mercedes ASMR video and all of the responses). Becca and Robin have utilized ASMR videos for relaxation and stress-management for the past 10 years. Beryl and Becca thought this could be a great resource for students.

Veggie Meat Alternatives: A Virtue-Ethical View, Carlo Alvaro

Publications and Research

This chapter discusses practical and ethical aspects concerning veggie meat alternatives. Upon consideration, it is argued that while the production, sale, and consumption of veggie meat alternatives seemingly contribute to a solution to environmental problems, we ought to consider veggie meat alternatives from a virtue-ethical perspective concerning human excellence and flourishing. Doing so reveals previously unexplored ethical reasons for not promoting the production, sale, and consumption of veggie meat alternatives. One reason in particular is that veggie meat alternatives stem from the lack of the virtue of temperance.

Heterogeneity In Maternal Mrnas Within Clutches Of Eggs In Response To Thermal Stress During The Embryonic Stage, Atsuko Sato, Yukie Mihirogi, Christine Wood, Yutaka Suzuki, Manuela Truebano, John Bishop

School of Biological and Marine Sciences

Background: The origin of variation is of central interest in evolutionary biology. Maternal mRNAs govern early embryogenesis in many animal species, and we investigated the possibility that heterogeneity in maternal mRNA provisioning of eggs can be modulated by environmental stimuli. Results: We employed two sibling species of the ascidian Ciona, called here types A and B, that are adapted to different temperature regimes and can be hybridized. Previous study showed that hybrids using type B eggs had higher susceptibility to thermal stress than hybrids using type A eggs. We conducted transcriptome analyses of multiple single eggs from crosses using eggs …

Phase I Study Of Mtorc1/2 Inhibitor Sapanisertib (Cb-228/Tak-228) In Combination With Metformin In Patients With Mtor/Akt/Pi3k Pathway Alterations And Advanced Solid Malignancies, Vivek Subbiah, Niamh Coleman, Sarina A Piha-Paul, Apostolia M Tsimberidou, Filip Janku, Jordi Rodon, Shubham Pant, Ecaterina E Ileana Dumbrava, Siqing Fu, David S Hong, Shizhen Zhang, Ming Sun, Yunfang Jiang, Jason Roszik, Juhee Song, Ying Yuan, Funda Meric-Bernstam, Aung Naing

Faculty, Staff and Student Publications

BACKGROUND: Sapanisertib (CB-228/TAK-228) is a potent, selective ATP-competitive, dual inhibitor of mTORC1/2. Metformin is thought to inhibit the mTOR pathway through upstream activation of 5'-AMP-activated protein kinase (AMPK) suggesting combination therapy may enhance antitumor activity of sapanisertib. We report preliminary safety, tolerability, and efficacy from the dose-escalation study of sapanisertib in combination with metformin in patients with advanced solid tumors.

METHODS: Patients with advanced metastatic solid tumors resistant or refractory to standard treatment, with and without mTOR/AKT/PI3K pathway alterations, received sapanisertib 3 or 4 mg daily together with metformin once to three times daily (500-1,500 mg). All patients underwent 14-day …

Children in the workplace are becoming a more common discussion in various work environments, including libraries. Since the university has no policy addressing this issue, a task force was charged to draft a recommended policy for the university library regarding bringing children to the workplace. The task force reviewed existing policies and conducted a survey and interviews with library employees. The resulting policy provided guidelines for employees and their supervisors without being overly prescriptive. This article provides a case study of how the task force used assessment methods and tools to create an appropriate and inclusive policy. While the specific …

The Effect Of Breastfeeding Practices Of Undernourished Mothers In Rural Sierra Leone On Infant Growth And Mortality, Aminata Shamit Koroma, Kevin B Stephenson, Per O Iversen, Mark J Manary, David Taylor Hendrixson

2020-Current year OA Pubs

Breastfeeding provides optimal infant nutrition; however, <50% of infants are exclusively breastfed (EBF) for 6 months. We aimed to describe breastfeeding practices and their effects on growth and mortality among a high-risk mother-infant cohort in rural Sierra Leone. This was a secondary analysis of data from a randomized nutrition intervention trial among undernourished pregnant women. The study's primary outcomes were infant weight and length gains at 6 weeks of age. We included 1270 singleton infants in the analysis, with 1092 (85.6%) having 24-week outcome data. At 6 weeks, 88% were EBF, but the rate of EBF decreased to 17% at 24 weeks. The EBF infants at 6 weeks had improved length (difference of 0.9 mm/week; 95% CI 0.4 to 1.3;

Fruit Forage Integrated Systems For Diversification And Other Ecosystem Services, S. Ahmad, N. H. Mir, S. S. Bhat

IGC Proceedings (1977-2023)

The interspaces (alleyways) in fruit orchards are generally not utilized for cultivation of perennial forage crops by a majority of farmers. These alleyways are often occupied by weeds or kept bare or clean with repeated tillage. The weeds may act as alternate/collateral hosts, thereby harboring pests and pathogens that may harm the fruit trees. In addition to this, the frequent tillage may subject the soil to erosion losses. Intercropping of perennial forage grasses and/or legumes with fruit crops is thus beneficial for not only providing high quality forage but also for providing various ecosystem services.Owing to an ever burgeoning population, …

IGC Proceedings (1977-2023)

Two systems of grass farming were compared in an eight-year experiment in West Virginia, USA. The grassland consisted primarily of cocksfoot (Dactylis glomerara L.), Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), and red (Trifolium pretense L.) and white clover (T. repens L.). The objective was to compare two systems of beef cow calf production. The experiment was a randomized complete block with two replicated treatments. The grassland of treatment 1 (system 1) was overseeded with legumes, grazing started 1 wk earlier and continued 1 wk later than treatment 2 (system 2) and …

Grazing Cover Crops In The Eastern Us: Performance Of Sheep, Goats, And Cattle Grazing Brassica Cover Crops, K. Cassida

IGC Proceedings (1977-2023)

Grazing annual forage crops has attained new interest with the increase in use of cover crops. Grazing annual forages grown as cover crops not only allows livestock producers to extend the grazing season but also gives row crop growers a way to recoup the cost of planting cover crops through grazing leases. Species in the Brassicaceae family (turnip, rape, kale, radish, and hybrids) have wide adaptability across the eastern US, excellent forage yield potential, and extremely high nutritional value. Brassicas are sometimes described as “high-moisture concentrates.” Their low effective fiber content drives the common recommendation to grow them with annual …

Isoflavones In Legumes As Functional Forages And Feeds In Ruminant Grazing Systems, B. E. Davis, Michael D. Flythe, T. A. Hamilton, D. G. Ely, L. H. Anderson, J. R. Weinert-Nelson

IGC Proceedings (1977-2023)

Legumes are often utilized in livestock grazing systems to improve diet quality, diversity, and consequently animal performance. In addition to their nutritional utility, legumes contain phytoestrogenic isoflavones that have selective antimicrobial activity in the rumen and once absorbed can cause arterial vasodilation. These added bioactive functions of isoflavones suggest that legumes could be strategically utilized in grazing systems as functional forages to improve ruminant performance and health. The objective of this presentation will be to discuss past and current research on the application of isoflavones via legumes as an antimicrobial for growth promotion and as a mitigation strategy for fescue …

Cool-Season Annual Legumes And Forbs For Grazing And Cover Crop Systems, S. L. Dillard

IGC Proceedings (1977-2023)

Annual forage legumes and non-leguminous forbs can be used to interseed into perennial forage grasses or as a short-term grazing option between row crop rotations. Diversification of cropping systems by increasing number or type of cover crops in crop rotation plays an important role in improving land-use efficiency and in promoting sustainable agriculture. Legumes and other broadleaf forages provide increased forage digestibility and crude protein as a result of their greater leaf-to-stem ratio. In the Southeast U.S, few novel cultivars have been released in the last 20 years, resulting in the reliance on only a few forage cultivars and species. …

Animal And Forage Performance Of Integrated Crop-Livestock Systems, S. L. Dillard

IGC Proceedings (1977-2023)

Grazing of cool-season cover crops has been shown to be a viable tool for extending the grazing season while mitigating environmental risks associated with row-crop farming systems. Grazing cover crops is not novel, but most recent information available on this practice focuses on soil health as opposed to forage production and animal performance. Research has shown that forage quality of cool-season annual cover crops is sufficient to maintain an average daily gain of at least 1 kg/d and as high as 1.5 kg/d. Forage species selection plays an important role in the success of an integrated crop-livestock system. Grasses typically …

Swath Grazing: Feeding “Hay” Without The Production Expenses, V. Baron, A. C. Dick, A. Omaha

IGC Proceedings (1977-2023)

Swath grazing is a practice for overwintering beef cows on small grain forage left in the field to graze through snow, but annual variation occurs. The objective is to review 18 years of research at Lacombe, Alberta (AB) to describe how production attributes are related to cost mitigation and cow performance. Five trials compared swath grazing management options to pen-fed controls to determine feasibility. Associated studies monitored forage quality, soil fertility requirements and planting date impacts on yield. Mean, standard deviation, coefficient of variation, maximum and minimum values (n=18) for forage yield, pasture days, carrying capacity and percent utilization were …

IGC Proceedings (1977-2023)

Native warm-season grasses (NWSG) can produce high quality forage and high rates of gain for beef cattle. However, little data is available on how NWSG affect the productivity of cow-calf operations on a farm scale. Therefore, we implemented an experiment at three sites, Booneville, AR, Linneus, MO and Louisville, TN, with cow-calf pairs (mature cows over ≥ 3 years old, spring calving). We evaluated two forage systems that mix either a drought or drought/flood tolerant native C₄ species [big bluestem (BB) blend or eastern gamagrass (EG)] with a cool-season perennial, tall fescue (TF), and compared them to the most …

Fodder Scenario And Hortipastoral Opportunities To Enhance Fodder Production In India, Nagaratna Biradar, C. Lakshmi Devi, Vinod Kumar, Narendra S. Kulkarni, G. K. Kumar Anil, S. S. Guledagudda, A. Bheemappa

IGC Proceedings (1977-2023)

Food grain production and livestock production are closely related in India as crop-residue forms the major source of fodder for livestock. It’s thus assumed that increase in food grain production has positive effect on availability of dry matter to the livestock. Using land use classification, crop production (2015 to 2020) and livestock census (2019) data, dry matter (DM) availability for livestock for 28 states of India was estimated. Hortipastoral opportunities by estimating area available under orchards in southern India were done to assess the possibility of introducing fodder crops in orchards. Some of the fodder crops were introduced in orchards …
