Development Of High-Fiber Belgian Waffles And Evaluation Of Product Acceptance, Product-Elicited Emotion, And Purchase Intent By Millennial Consumers, 2253299685 Velasquez

LSU Master's Theses

Dietary fiber may help reduce LDL cholesterol levels and prevent cardiovascular diseases. The US-FDA recommends 14g of fiber/1000kcal consumed, but Americans consume/day. A product containing ≥5 grams of fiber/serving can be claimed as a high-fiber product. Adding dietary fiber to food affects their physicochemical properties and sensory quality, possibly leading to less product acceptability. This study was performed to assess selected physicochemical properties and consumer perception of “high-fiber” Belgian waffles. Waffles were formulated to have fiber contents of


Pasture Management To Improve Dry Matter Intake, Marcus F. Rose, Earl Creech, Blair L. Waldron, S. Clay Isom, Michael Peel, Kara Thornton-Kurth, Jacob Hadfield, Kerry A. Rood Apr 2020

Pasture Management To Improve Dry Matter Intake, Marcus F. Rose, Earl Creech, Blair L. Waldron, S. Clay Isom, Michael Peel, Kara Thornton-Kurth, Jacob Hadfield, Kerry A. Rood

All Current Publications

Agricultural producers are constantly looking for ways to maximize returns while reducing input costs. On dairy operations, a move from confinement feeding to pasture grazing offers the potential to reduce costs associated with harvest and storage of feed. In such a transition, producers sometimes report a decline in milk production and growth of livestock—both of which can strongly correlate to dry matter intake. Fortunately, dry matter intake is something that can be influenced by management practices. In this publication, we discuss the pasture management practices to improve dry matter intake.


Considerations For Crop Rotation From Alfalfa To Corn, Earl Creech, Matt Yost, Grant Cardon, Corey Ransom, Jason Clark Apr 2020

Considerations For Crop Rotation From Alfalfa To Corn, Earl Creech, Matt Yost, Grant Cardon, Corey Ransom, Jason Clark

All Current Publications

The importance of rotating out of a declining alfalfa stand is well established. As the alfalfa stand ages, forage yield and quality decline, while weed, insect, and disease pressures increase. Terminating the stand and growing one or more other crops for several (2–3) years allows a grower to press the reset button on a piece of ground. These years of growing another crop will result in more productive alfalfa when a new stand is planted again.

A Global Perspective On Sustainable Intensification Research, Kenneth Cassman, Patricio Grassini Apr 2020

A Global Perspective On Sustainable Intensification Research, Kenneth Cassman, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Despite general agreement that meeting food demand without further loss of natural ecosystems requires sustainable intensification, there is little dialogue about the research agenda needed to achieve it. To that end, we evaluate current trajectories towards sustainable intensification, review published research on the topic, identify missing links, and propose a prioritization framework to fill gaps. Although progress towards sustainable intensification is behind schedule, we are optimistic that current trends can get back on course assuming a well-prioritized and adequately funded research portfolio and appropriate policies and institutions to support it.

Shifting Landscapes: The Effects Of Male Out-Migration On Food Security And Food Sovereignty In Rural Nepal, Emma Brown

Independent Study Project (ISP) Collection

Rural Nepal is experiencing rapid demographic changes, significantly impacting the socioeconomic and agricultural landscape of these areas. Growing percentages of the male population are migrating out of the country in search of better livelihood opportunities. This is largely a result of poor development processes and governmental policies that have failed to create adequate domestic livelihood opportunities and incentives to work in agriculture, as well as changing ideas on what it means to be successful, spurred by globalization. Further, dominant neoliberal ideology and the commercialization of agriculture is decreasing the profitability of agriculture, making migration a lucrative option. Due to out-migration, …

Investigating Microbiomes And Developing Direct-Fed Microbials To Improve Cattle Health, Alison C. Bartenslager Apr 2020

Investigating Microbiomes And Developing Direct-Fed Microbials To Improve Cattle Health, Alison C. Bartenslager

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

Over the last decade, global beef production has increased to meet the protein needs of the growing population. As a result, the intensification of beef cattle production systems has resulted in broad spectrum prophylactic use of antibiotics and growth promoting agents. With increased concern around antimicrobial resistance (AMR) and emergence of novel pathogenic strains of bacteria, it is critical to understand disease progression and associated changes in the microbiome to develop novel therapeutic alternatives to reduce antibiotic use and control disease. One such approach that is currently being investigated is the development of novel direct-fed microbial strains to outcompete pathogens …

Swanson Apr 2020

Heat Stress-Induced Deficits In Growth, Metabolic Efficiency, And Cardiovascular Function Coincided With Chronic Systemic Inflammation And Hypercatecholaminemia In Ractopamine-Supplemented Feedlot Lambs: Atypical Cyclicity At Puberty In Beef Cows Is Associated With Early Deficits In Muscling, Metabolic Indicators, And Myoblast Function In Offspring But Does Not Impact Feedlot Performance, Rebecca M. Swanson

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

Our 1st study evaluated the effects of b-adrenergic agonist (ractopamine) supplementation on growth, health, and wellbeing in heat-stressed feedlot wethers. Chronic heat stress impaired growth, metabolism, and wellbeing even when the impact of reduced feed intake was eliminated by pair-feeding. We observed systemic inflammation and hypercatecholaminemia that were likely mediators of these deficits. Moreover, ractopamine did not diminish any wellbeing indicators and improved muscle growth without worsening the effects of heat stress.

Our 2nd study assessed the effects of pubertal cyclicity (weaning to 1st breeding) in cows on myoblast-mediated muscle growth, metabolism, and growth efficiency of their …

Comparison Of Comprehensive Health Score In North American Housed Giraffe And Free-Ranging Giraffe From South Africa, Haley Beer Apr 2020

Comparison Of Comprehensive Health Score In North American Housed Giraffe And Free-Ranging Giraffe From South Africa, Haley Beer

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

Stress is evident in many animal species and has been correlated to disease prevalence. During stressful events, allostasis is initiated by physiologic systems to maintain or reestablish homeostasis to protect an organism’s viability. Over time, the acclimation to frequent stress causes systematic dysregulation, leading to the phenomena of increased allostatic load. Allostatic load has been assessed in animal species via serum through selection of representative, multi-system biomarker indices. Perception and number of stress events may impact dysregulation severity, yielding allostatic load as a predictive tool. However, the allostatic load methodology poses application limitations to individuals without historical data and those …
