Oat Grazing: Forage Composition And Supplementation Response, A J. Freddi, M J. Arzadun, A A. Pissani, P Sastre

IGC Proceedings (1977-2023)

Oat forage (Avena sativa), which has low soluble carbohydrates (SC) and high soluble protein (SP) content, can reduce liveweight gain of grazing animals; supplementation with grain and low degradability protein may serve to counteract the effect. A grazing trial was carried out on two soils with different nitrogen (NO3 -) availability, from 16 April 1994 to 6 September 1994. Steers were randomly allocated to 3 treatments: low nitrogen (LN), high nitrogen (HN) and high nitrogen with supplementation (HNS). Forage of LN showed lower SP (p<0.05) during the first month of grazing, and higher SC (p<0.05), than HN during the first two months of the trial. Animal liveweight gain was: 892, 909 and 775 g/an/day for LN, HNS and HN, respectively, with animals in HN of significantly lower liveweight gain (p<0.05). Under the conditions of this trial, animals grazing on oat forage with lower SC and higher SP had lower liveweight gain and responded to supplementation.

Three systems, 1) native range with pelleted soybean or cottonseed meal as winter protein supplement (NC); 2) native range with wheat pasture (NW); and 3) Plains Bluestem with wheat pasture (PB) were compared. Protein supplements were given twice weekly and cows grazing wheat pasture were allowed 6 hrs to graze. Cows on NW were heavier with higher condition at breeding in the spring of 1994 than those on NC and cows on PB were heavier and …

Relationship Between Height And Sward Quality In Rotational Dairy Systems, M R. Mosquera-Losada, A Gonzalez-Rodriguez

IGC Proceedings (1977-2023)

Height is a good guide for management in dairy systems.Intake by dairy cows depends on amount offered and quality of pasture and for this reason a relationship between that offered and pasture quality with height should be studied. The experiment was conducted in NW of Spain with three different stocking rates in dairy systems. A lower quality sward was found in the taller offered pasture as indicated by its higher ADF and lower CP percentages. Total sward ADF (kg x ha-a) was higher in taller offered pasture, which indicated a lower pasture quality, however the total CP was positively related …

Breastfeeding As Co-Occupation: Occupational Therapy’S Role In Promoting Health And Well-Being, Lisa Joelle Sutton, Julie D. Kugel, Dragana Krpalek, Arezou Salamat

The Open Journal of Occupational Therapy

Background: Even with efforts to encourage mothers to breastfeed exclusively for the first 6 months, the majority of women are not able to undertake breastfeeding as the sole means of infant nutrition provision for various reasons. The role of occupational therapists working with mothers who breastfeed is complex and not strongly supported in the literature. Therefore, this qualitative study was designed to examine the role that occupational therapists may engage in supporting mothers and infants in the co-occupation of breastfeeding.

Method: A qualitative phenomenological study design was applied and included 11 occupational therapists working with breastfeeding dyads. The …

An Investigation Of The Sub-Lethal Impacts To Pollinators From Pesticides, Emily Beahm

Theses

In order to feed a growing global population, agricultural practices must utilize pesticides to maintain high yields. Responsible use of pesticides should be based on literature confirming their efficacy and safety. When pesticides are not adequately investigated prior to their release, there can be severe consequences. Many highly effective pesticides, such as the class neonicotinoids, were allowed to be used commercially prior to thorough assessment of their environmental risks, resulting in consequences that largely have fallen to the exposed pollinator populations. To avoid similar outcomes, I tested the popular biopesticide Botanigard which contains Beauveria bassiana, an entomopathogenic fungus previously exposed …

Provider Implementation Of Probiotics As An Adjuvant Treatment Modality For Patients With Anxiety And Or Depression In A Primary Care Setting, Sarah Dedmon

Doctoral Dissertations and Projects

The prevalence of anxiety and depression among Americans is growing rapidly. Patients are seeking out traditional treatments as offered by their primary care providers, but also frequently look toward integrative or complementary methods of managing their symptoms. The use of dietary supplements is at an all-time high, yet the U.S. Food and Drug Administration does not regulate these substances for potency and purity or evaluate them using quality standards as it does pharmaceuticals. Most providers lack education regarding the physiological interaction their patients may experience when using these substances and are naïve to their place in primary care medicine. The …

Educating Nurses On The Components Of A Healthy Work Environment, Kathryn L. Scott

Doctoral Dissertations and Projects

It is essential to look at the entire picture to ensure patient care is offered in the highest quality manner possible. One must look at patient satisfaction, quality outcomes, and job satisfaction experienced by the nursing staff providing care to accomplish this goal. Research has shown that nurse burnout has increased exponentially as of late. Some blame the COVID-19 pandemic; others look at the generation of nurses graduating from nursing school and starting in the field, comparing the baby boomer nurse to the Gen Z nurse. Many factors are involved, and with the recent addition of paying particular attention to …

Digital Agriculture Applications In Maize Nutrient Management And Soybean Crop Stands Assessment, Bhawana Acharya

LSU Master's Theses

High soil moisture from frequent excessive precipitation can reduce maize (Zea mays L.) yield and increase nitrogen (N) loss. Early-stage soybeans (Glycine max) are also susceptible to damage under these conditions. Traditional methods for assessing N status in maize and plant stands in soybean are labor-intensive and time-consuming. In this study, UAV remote sensing was used to assess maize N status under different N rates and excessive soil moisture. For soybeans, we compared a blob detection method with the YOLOv8 model to estimate plant density using ground images from a handheld camera. Additionally, YOLOv8 performance was evaluated …

Systemic Interindividual Dna Methylation Variants In Cattle Share Major Hallmarks With Those In Humans, Wen-Jou Chang, Maria S Baker, Eleonora Laritsky, Chathura J Gunasekara, Uditha Maduranga, Justine C Galliou, Joseph W Mcfadden, Jessica R Waltemyer, Bruce Berggren-Thomas, Brianna N Tate, Hanxue Zhang, Benjamin D Rosen, Curtis P Van Tassell, George E Liu, Cristian Coarfa, Yi Athena Ren, Robert A Waterland

Faculty, Staff and Students Publications

BACKGROUND: We recently identified ~ 10,000 correlated regions of systemic interindividual epigenetic variation (CoRSIVs) in the human genome. These methylation variants are amenable to population studies, as DNA methylation measurements in blood provide information on epigenetic regulation throughout the body. Moreover, establishment of DNA methylation at human CoRSIVs is labile to periconceptional influences such as nutrition. Here, we analyze publicly available whole-genome bisulfite sequencing data on multiple tissues of each of two Holstein cows to determine whether CoRSIVs exist in cattle.

RESULTS: Focusing on genomic blocks with ≥ 5 CpGs and a systemic interindividual variation index of at least 20, …

"A Life Altering And Special Journey": The Lasting Impact Of Mindfulness On Semester-Long Study Abroad Participants, Ana Conboy, Kevin Clancy

Journal of Contemplative and Holistic Education

Education abroad is held up as a high-impact practice with the potential to engage college and university students in a transformative learning experience (Kuh, 2008). The Institute for International Education (IIE) reports that 347,099 U.S. students received academic credit for study abroad during the 2018-2019 academic school year (IIE). Extensive research into student learning gains abroad have demonstrated that developing student metacognition, or one’s ability to be intentionally self-reflective, is central to transformative learning in the study abroad experience (Vande Berg et al., 2012; Zull, 2012). Consequently, international educators are continually searching for pedagogies (praxis) to facilitate metacognitive learning within …

The characterization of human behavior in real-world contexts is critical for developing a comprehensive model of human health. Recent technological advancements have enabled wearables and sensors to passively and unobtrusively record and presumably quantify human behavior. Better understanding human activities in unobtrusive and passive ways is an indispensable tool in understanding the relationship between behavioral determinants of health and diseases. Adult individuals (N = 60) emulated the behaviors of smoking, exercising, eating, and medication (pill) taking in a laboratory setting while equipped with smartwatches that captured accelerometer data. The collected data underwent expert annotation and was used to train a …

Set-Based Tests For Genetic Association Studies With Interval-Censored Competing Risks Outcomes, Zhichao Xu, Jaihee Choi, Ryan Sun

Faculty, Staff and Student Publications

Over the past decade, massive genetic compendiums such as the UK Biobank have gathered extensive genetic and phenotypic data that hold the potential to provide unparalleled insight into the genetic etiologies of various complex diseases. However, much of the disease information is collected as time-to-event outcomes in interval-censored form, and conventional tools for genetic association analysis are often not available for this type of data. For example, set-based inference for common and rare variants analysis is a fundamental investigation in germline genetics studies, but there is a lack of approaches that can perform set-based testing when the interval-censored outcome of …

Towards Addressing Mental Health In Rural Louisiana: Blueberry Supplementation As A Natural Intervention, Katy E. Venable

LSU Doctoral Dissertations

Depression and anxiety are major public health issues; however, there is an unmet need for novel effective and accessible treatments, particularly in rural communities. Blueberries are an unexplored nutraceutical for these conditions due to their excellent nutritional profile, with particularly high levels of polyphenols and anthocyanins and benefits on mood, cognition, and health. Therefore, we conducted a double-blind, randomized pilot study in a rural population.

Triceps Surae Muscle Forces During Walking And Dancing Across Varied Footwear, Elias Wallnöfer, Clara Egner, Robert Csapo, Arnold Baca, Hans Kainz

ISBS Proceedings Archive

Despite a high prevalence for Achilles tendinopathies in athletic populations, research on individuality in muscle coordination, a possible contributor to this disorder, is limited. Effects of shoe condition and kinematics on force share between triceps surea muscles during normal gait and a dance step were investigated and compared between two methodological approaches. Muscle coordination was analyzed based on musculoskeletal simulations in a generic and an electromyography-informed approach. The electromyography-informed mode revealed higher individuality and a higher force production in medial gastrocnemius for the dance step in high heels compared to bare foot. The study underscores the importance of viewing Achilles …

ISBS Proceedings Archive

Stretching is common, yet little work has explored the influence of stretch intensity and sex differences in response to stretching. We investigated the acute effect of static pectoral stretching at two intensities (110 and 120%) on pectoralis minor length, horizontal abduction range of motion (HA-ROM), and pectoralis major and minor stiffness using shear wave elastography in males and females. Twenty-four participants (N=24, 12 female; age: 25±4.6) attended two sessions where they received three sets of a randomized stretch for 30s with 30s rest between. There were no differences in pectoralis minor length, HA-ROM, or pectoralis minor or major …

Effects Of Short Vs. Long Warm-Up Protocols On Biomechanics And Performance In A 50- M Swimming Trial, Marina Gil Calvo, Mario Asensio Moreno, Daniel Boullosa

ISBS Proceedings Archive

The purpose of this study was to compare the effect of two warm-up, protocols differing in volume, on biomechanical and performance parameters in a simulated 50m freestyle swimming trial. Twelve well-trained male swimmers of regional and national levels performed, in random order, two 50-m time trials on separate days, after a 600m, 12 min warm-up (Short Warm-Up, SWU) or a 1200m, 24 min warm-up (Long Warm-Up, LWU) protocols in random order. The results show that only the SWU warm-up protocol significantly improved swimming performance, although there is no difference between protocols in most kinematic parameters.

Dynamic Versus Self-Proprioceptive Neuromuscular Facilitation Stretching On Vertical Jump Performance, Jason Wicke, Ashley Pauly, Alicja Swiechowska, Giuliana Pocino

ISBS Proceedings Archive

Most warm-up routines are performed without the help from coaches or trainers. Warm-up routines often include a stretching component. The purpose of this study was to determine whether self-PNF is comparable to dynamic stretching prior to performing a vertical jump. Twelve participants performed pre- and post-intervention vertical jumps in random order and at least 48 hours apart. Interventions included dynamic stretching, self-PNF and a control. No significant differences (p > 0.05) were found between or pre- versus post-intervention for vertical jump height and peak force. However, there was a slight increase in both measures for post-dynamic stretching and a slight decrease …

Using Participant Descriptive Characteristics, Heart Rate And Inertial Sensors To Estimate Running Economy, Krista Vohlakari, Sailee Sansgiri, Timo Rantalainen, Esa Hynynen, Neil Cronin

ISBS Proceedings Archive

In this study, we aimed to develop a machine learning algorithm to estimate running economy. Inertial sensor, heart rate and participant descriptive characteristics were used to estimate running economy by training and comparing five different machine learning models. Fourteen subjects performed a VO₂max running test on a treadmill with four-minute stages. Submaximal running speeds (lactate level < 4 mmol/l) were used to train the models. The best-performing model was a k-nearest neighbour regressor, which achieved average root mean square error of 0.097 ± 0.059 kcal/kg/km and average mean absolute percentage error of 8.7 ± 5.8 % compared to ground truth running economy data. Despite reasonably accurate running economy estimates, the model is currently not very generalisable, probably due to the small dataset used for training.
