Forage Production And Nutritive Value Of Cynodon Spp. Under Grazing In Puerto Rico, L E. Tergas, Y Q. Cabrera, A Sotomayor Rios

IGC Proceedings (1977-2023)

Livestock production in the tropics is highly dependent on forages to meet the nutritional requirements of grazing cattle. However, seasonal fluctuations on dry matter production and nutritive value are limiting factors affecting animal perform­ance and production. Stargrass Cynodon nlemfuensis var. nlemfuensis is a highly productive grass recommended for intensive management in the humid tropics of Puerto Rico (Vicente-Chandler et al., 1974). Bermuda Cynodon dactylon and Stargrass produced high yields of quality forage and persisted under intensive grazing in the humid northern coastal plains of Puerto Rico; however, the average production of both grasses was related to rainfall distribution, decreasing during …

Prediction Of The Yield Of Nutritive Matter In Some Autumn Cut Forage Catchcrops, K Kastelic, J A. Nikolic, A Pavlicevic, T Stupica, J Cizec

IGC Proceedings (1977-2023)

Arable land often lies fallow for a time, which provides an opportunity for growing fodder catchcrops between two main crops. This practice should improve the soil structure, conserve soil moisture, eliminate many weeds, maximise land use and enable easier preparation for the subsequent main crop. More­over, subsequent cereal yields may be increased by preceding forage legume crops (Papastylianou and Samios, 1987). The aim of present investigation was to determine the concentration of promising autumn cut catchcrops (D-value) and to assess the possibility of predicting the yield of digestible organic matter (DOM) from the yield of green or dry matter (DM).

Fiber Composition Of Successive Cuts Of Lucerne, D Kolarski, J Pavesic-Popovic,, O Krstic, K Koljajic

IGC Proceedings (1977-2023)

The plant cell walls contain lignin, cellulose, hemicellulose, fiber bound protein and fiber bound minerals. Their nutritive value is limited by their degree of lignification, while cell con­tents is not limited (Barton et al., 1977). Type and extent oflig­nin-polysaccharide bounding could affect digestion more than amount of lignin (Jung et Fahey, 1983). The purpose of these studies was to determine chemical and fiber composition of four cuts of lucerne (Medicago sativa, CV Kl).

Relationship Between The Mineral Content In Pastures And The Content Of These Elements In Blood Serum In Dairy Cows, A Lachowski, I Kuczynska, W Wojciechowski

IGC Proceedings (1977-2023)

Grass tetany, a conditioned Mg deficiency of improper K: (Ca + Mg) ratio is a nutritional problem in various parts of Poland. The aim of the investigations was to determine to what degree the mineral content of grasses in the pastures influenced the mineral content in blood serum in dairy cows. This is very important when the animals are grazing and when cattle slurry is used on grasslands. In the literature we can find opinion con­sidering hypomagnaesemia as a metabolic disorder of rumin­ants typified by low blood serum Mg and generally accompanied by hypocalcemia. It has been related to low …

Characterization Of Biological Properties Of Fodder Value Of Dandelion, Taraxacum Officinale Web., M Falkowski, I Kukulka, S Kozlowski

IGC Proceedings (1977-2023)

In recent years the quantities of dandelion appearing on newly established grasslands has increased quite significantly. In such conditions it can no longer be treated as a meadow herb whose fodder value, according to European literature, equals half of that of valuable fodder plants. Becoming a weed, dan­delion has been the object of investigations on ways of elimina­ting it from the sward by means of herbicides (Schlotter et al., 1988). At the same time, experiments are under way on biologi­cal properties of dandelion with the aim to explain the causes of its expansion. It was found that there is an …

Effect Of Fertilizers On Cutting On Time On Chemical Composition Of Sward From Permanent Meadow, A Golob, Zdenka Berloznik, M Leskosek, Vekoslava Stibilj

IGC Proceedings (1977-2023)

Ecological problems and surpluses of milk and meat have given rise to less intensive systems of grassland utilisation. One of such system is utilisation of air nitrogen via legume sym­biosis with nitrogen fixing bacteria. In Slovenia, where conditions for legume growth are more favourable than in NW Europe, natural meadows fertilized with P and K only give reasonable yields - on average around 7 t DM per ha (Leskosek, 1981). Most legumes suffer after fre­quent defoliation so such meadows should be defoliated only 2- 3 times during the growing season. Under less frequent cutting regime nutritive value of forage is …

Determination Of Condensed Tannins In Tropical Legume Forages, L Telek

IGC Proceedings (1977-2023)

The effect of condensed tannins (proanthocyanidins) in ruminant nutrition is complex and needs further interdiscipli­nary reinvestigations with improved analytical methods. With the « cell rupture » theory of legume pasture bloat (Howarth et al., 1978), the role of condensed tannins seems to be secondary; they are acting as protein precipitants (Goplen et al., 1980) and inhibiting microbiological proliferation in cell­ular spaces (Howarth et al., 1982). Their assumed interference with digesting enzymes in vivo is doubtful (Mole and Water­man, 1985). On the importance of condensed tannins in nutrition, several reviews were published (McLeod, 1974; Tempel, 1982; Kumar and Singh, 1984 and …

Screening Sericea Lespedeza Germplasm For Tannin Concentration In The Leaves And Herbage Palatability, J C. Petersen, J A. Mosjidis, N S. Hill

IGC Proceedings (1977-2023)

Several million hectares in the subtropical world are currently used as grazing land for beef and dairy cattle, how­ever, in many cases animal production is very low. To improve animal nutrition, cultivated legume species can be introduced. Sericea lespedeza has potential and could be utilized in the acid soils of the· subtropics. Generally, sericea is low in palatability and nutritive value because its leaves contain tannins, which have long been associ­ated with low intake and reduced digestibility. Tannins are responsible for an astringent or bitter taste caused by the pre­cipitation of salivary glycoprotein (Goldstein and Swain, 1963). Chopping or macerating …

Gene X Environment Interactions: Polygenic Scores And The Impact Of A Early Childhood Intervention In Colombia, Orazio Attanasio, Gabriella Conti, Pamela Jervis, Costas Meghir, Aysu Okbay

Discussion Papers

We evaluate impacts heterogeneity of an Early Childhood Intervention, with respect to the Educational Attainment Polygenic Score (EA4 PGS) constructed from DNA data based on GWAS weights from a European population. We find that the EA4 PGS is predictive of several measures of child development, mother’s IQ and, to some extent, educational attainment. We also show that the impacts of the intervention are significantly greater in children with low PGS, to the point that the intervention eliminates the initial genetic disadvantage. Lastly, we find that children with high PGS attract more parental stimulation; however, the latter increases more strongly in …

Impact Of Menstrual Cycle Phase On Upper Extremity Function, Emma D. Cochran, Kaitlyn M. Armstrong

Honors Theses

Abstract

The Impact of Menstrual Cycle Phase on Upper Extremity Function

Background: There has been a significant rise in the number of female athletes participating across the spectrum of sports. While there are a multitude of research studies looking at physiology in sports on performance, training methods, and injuries; this research is general across genders. When it comes to female-specific physiology concerning training and injuries, there is little research. One such gender-specific physiological focus is the menstrual cycle in the female population. The literature suggests changes in joint laxity and muscle repair throughout the various phases of the menstrual cycle, …

Resource-Oriented Music Therapy For Musicians' Maladies, Chelsea Ventura, Chelsea Ventura

Expressive Therapies Theses

Professional musicians often experience various stressors brought on by perfectionist training routines, racial and gender disparities, and other occupational challenges. This thesis aims to inform music industry professionals, music educators, and mental health clinicians of the psychological and physiological struggles professional musicians experience with a focus on music performance anxiety (MPA) and music-induced harm (MIH). Findings from this literature review indicate that musicians who identify as BIPoC or female struggle more with mental health and their musician identities than white, male-identifying musicians. The published literature tends to explore treating musicians’ mental health with Western-rooted cognitive behavioral therapy and has under-explored …

Stress And Glucose Regulation In Adults At Risk For Type 2 Diabetes Mellitus: A Secondary Analysis From A Randomized Controlled Trial, Sophia Lysne, Regina Dispa, Brenna Way, Bea Francene Pilnade, Donya Shahamati, Romina Ballesteros, Christopher Acosta, Keren Morales, Esther Adaji, Ohis Egbaidomeh

Undergraduate Research Symposium Posters

Type 2 Diabetes Mellitus (T2DM) is a major public health concern, significantly increasing the risk of cardiovascular diseases (CVDs). Additionally, prediabetes is a critical precursor, as it elevates the risk of developing both T2DM and CVDs. (2)

Recent literature reveals among individuals with severe perceived stress, there is a higher likelihood of HbA1c% levels meeting the criteria for prediabetes (5.7– 6.4%) as compared to those with lower perceived stress. (3)

Studies show that psychological stress has hyperglycemic effects in individuals with T2DM, suggesting that stress is associated with poorer blood glucose control. (4)

Know Thyself: A History Of Ancient Neuroscience, Alex Delano

Departmental Honors & Graduate Capstone Projects

Neuroscience is often described as one of the youngest bodies of science, but documented study of the brain begins as early as the Neolithic period. The ancient Mediterranean was a hub for science, mathematics, philosophy, and literature, all disciplines necessary for the study of the brain. Evidence of neurosurgical procedures like trepanation and craniotomy began in the Neolithic period and were practiced and improved upon throughout the ancient Mediterranean. The first detailed studies on brain anatomy were carried out in the 3^rd century BCE in Greece which created a necessary structure for future scientists to build on. While many …

A Multimodal Intervention To Improve Treatment And Clinical Outcomes In Children With Recurrent Otitis Media, Daniel Courtaney

Evidence-Based Practice Project Reports

Acute otitis media is the number one cause for primary health care visits and antibiotic prescriptions in the pediatric population (El Feghaly & Jackson, 2023). Upwards of 27% of children experience multiple episodes of otitis media (OM) that meet recurrent otitis media (ROM) diagnosis criteria (Pelton & Marchisio, 2023). Guided by the Iowa Model (Iowa Model Collaborative, 2017), the project’s purpose was to implement a multimodal intervention to decrease recurrent OM and repeat clinic visits. A comprehensive literature search of 5 databases yielded 16 sources ranging from levels I-IV (Melnyk & Fineout-Overholt, 2023). Using the AGREE II and JBI Critical …

Conflict, Human Development, And Neonatal Health: A Regional Analysis Of The Eastern Mediterranean, Zynub A. Al-Sherri

Honors Theses

Background. The effects of war and conflict on a population are direct and indirect in nature. One of the most devastating consequences is the destruction of healthcare infrastructure, which severely disrupts access to essential services and impedes long-term socioeconomic development. Among those most affected are newborns, as the neonatal period represents the most vulnerable stage of a child’s life and serves as a sensitive indicator of a society’s overall health and socioeconomic conditions. Given the persistent instability in the Eastern Mediterranean Region (EMR), this study aimed to explore how conflict and human development are associated with neonatal health outcomes …

Assessing The State Of Nutrition Education In Michigan Medical Schools, Sarah Bdeir, James Meza, Kareem Tayeb

Conference Presentation Abstracts

Despite the National Academy of Science recommending a minimum of 25 hours of nutrition education, U.S. medical schools dedicate an average of only 19 hours, and 75% lack mandatory clinical nutrition classes¹. Alarmingly, only 14% of current healthcare providers feel confident discussing nutrition with patients, despite its critical role in disease prevention and management². To address this gap, we surveyed medical students at five of seven Michigan medical schools about their schools' approaches to culinary medicine, self-perceived competence, and recommendations for improving nutrition education curricula. The survey was given to key representatives at each medical school, who distributed the survey …

Role Of The Small Intestinal Microbiota In The Pathogenesis Of Environmental Enteric Dysfunction In Undernourished Children And Mothers, Clara Kao

Arts & Sciences Graduate Student Theses and Dissertations

Undernutrition in women and its propagation in their children remains a major global health challenge. Worldwide, one in five children under five years of age manifests undernutrition as impaired linear growth, or stunting. Stunting, defined as having a length-for-age z-score (LAZ) <-2, is associated with poor developmental outcomes, including impaired neurodevelopment and immune responses. Furthermore, stunting and its long-term sequelae persist across generations, contributing to an intergenerational cycle of undernutrition. Existing nutritional interventions fail to substantially improve stunting, highlighting the need to (i) better understand other factors contributing to stunting and (ii) focus clinical efforts towards treating maternal undernutrition. Environmental enteric dysfunction (EED) is a subclinical inflammatory enteropathy of the small intestine proposed to contribute to stunting. EED is diagnosed histologically by blunted intestinal villi, epithelial barrier disruption and an immunoinflammatory infiltrate in the lamina propria. However, the pathophysiology of EED remains poorly defined. Furthermore, the small intestinal microbiota remains understudied due to difficulties in sampling. Evidence that the small intestinal microbiota contributes to EED pathogenesis comes in part from our collaborative work with colleagues at icddr,b (the International Centre for Diarrhoeal Disease Research, Bangladesh) who oversaw the Bangladesh EED (BEED) study. In this study children, aged 12-18 months residing in an urban slum in the Mirpur district of Dhaka who failed a nutritional intervention for their stunting, underwent esophago-gastroduodenoscopy (EGD) to obtain duodenal mucosal biopsies, aspirates of duodenal luminal fluid and plasma samples. A set of 14 bacteria taxa (defined by 16S rRNA amplicon sequencing) were identified in the duodenal microbiota of >80% of children with EED. Moreover, the absolute abundances of these ‘core taxa’ were positively correlated with duodenal mucosal and systemic inflammation in study participants and negatively correlated with linear growth. Our lab showed that introduction of a consortium of bacteria cultured from these duodenal aspirates, including these core taxa, produced small intestinal inflammation in young adult gnotobiotic, providing …
