Nourish: Promoting Body Acceptance Through Christ-Centered Identity In Female Collegiate Cross Country Runners, Kirsten E. Howland, Melinda B. Smith

Movement and Being: The Journal of the Christian Society for Kinesiology, Leisure and Sports Studies

Competitive runners are at increased risk for developing eating disorders (EDs), which can have serious effects on both sport and life. Clinical and psychological treatments for EDs are largely ineffective; therefore, to reduce the incidence of disordered eating in young runners, there is a need for preventative programs focused on shifting cultural attitudes and mindset. The purpose of this study was to implement and evaluate Nourish, a Biblically-based pilot program designed to promote body appreciation and a holistic view of the self through rooting identity in Christ. Seven members of the women’s cross country team at a private Division …

Turkish Journal of Zoology

As a sea turtle conservation area, Alas Purwo National Park (APNP) shows different patterns in the four species of turtles thathave nesting records, such as an increase in Olive Ridley Turtle (Lepidochelys olivacea), stability in Green Turtle (Chelonia mydas), anda decline in Hawksbill Turtle (Eretmochelys imbricata) and Leatherback Turtle (Dermochelys coriacea). During the survey, which lastedfrom January to July 2023, we discovered that each type of sea turtle preferred nesting sites at specific hypothetical stations, except forthe L. olivacea, which nested at all hypothetical stations along Pancur-Cungur Coast. We also discovered that it is highly encouragedto continue relocations that have …

Student Stress In Animal Science, Jayden Lynn Lawrence

Theses and Dissertations

Anecdotally, college students have high levels of stress when compared to the rest of the population. There have been many studies that support this idea in programs outside of animal science, but with the shift in animal science from students that have prior livestock experience to those that do not, it is important to acknowledge how this shift impacts the student population. By evaluating courses in animal science, and how they impact student stress it is possible to determine if the present-day curriculum causes any additional stress on students that have less prior experience. In the United States, a majority …

Resistance to immune checkpoint therapy (ICT) presents a growing clinical challenge. The tumor microenvironment (TME) and its components, namely tumor-associated macrophages (TAMs) and cancer-associated fibroblasts (CAFs), play a pivotal role in ICT resistance; however, the underlying mechanisms remain under investigation. In this study, we identify expression of TNF-Stimulated Factor 6 (TSG-6) in ICT-resistant pancreatic tumors, compared to ICT-sensitive melanoma tumors, both in mouse and human. TSG-6 is expressed by CAFs within the TME, where suppressive macrophages expressing Arg1, Mafb, and Mrc1, along with TSG-6 ligand Cd44, predominate. Furthermore, TSG-6 expressing CAFs co-localize with the CD44 expressing macrophages in the TME. …

Native Grasslands Of Yugoslavia As A Potential For "Biologically High Quality Food" Production - To Be Preserved And Used For The Benefit Of All, Djordjevic-Milosevic Suzana, Negovanovic Dragan, Zakonovic Miodrag

IGC Proceedings (1977-2023)

Natural grasslands are the base of the livestock production in the hilly-mountainous regions of Yugoslavia. Poor economic power of the owners of these areas brought about a complete dying out of agricultural production in these regions in the last few years. In the same time, the lack of financial resources made it impossible for the farmers to use the fertilisers, protective and other chemical agents which result in a high degree of environmental preservation. Due to current economic policy at this time the population has moved out and there is no industrialisation. The revival of agriculture on the hilly-mountainous regions …

Beef Cattle Production On Renovated Grass Pastures In Savannas Of Brazil, V.P B. Euclides, M.C M. Macedo, M P. Oliveira

IGC Proceedings (1977-2023)

A 3-year grazing trial was conducted, to study animal production on degraded grass pastures, renovated by two levels of fertilization. All paddocks were divided into halves: one received 1.5 t/ha of dolomitic limestone, 400 kg/ha of a fertilizer formula 0-16-18 and 50 kg/ha of microelements (FL1); and the other 3.0 t/ha , 800 kg/ha and 50 kg/ ha of the same fertilizers (FL2). Productivity on FL2 pastures was greater than that on FL1 pastures, averaging 565 and 395 kg of liveweight gain (LWG)/ha/year, respectively. For all grasses the productivity in both fertilizer treatments decreased linearly from the first to the …

Implementation Of Skin-To-Skin Immediately Post C-Section: A Pilot Study, Miah Vernor

Dissertations

Skin-to-skin contact during the golden hour is a practice that has numerous health benefits following the delivery of a newborn. These benefits include a healthy transition to extrauterine state, initiation of breastfeeding, thermoregulation, and more. However, the mode of delivery affects how often this practice is done. Parents who deliver vaginally are routinely offered the opportunity to perform skin-to-skin immediately after delivery whereas birth parents who deliver by cesarean section are not always offered this same benefit due to various reasons. A quality improvement project was conducted on an 18-bed labor and delivery unit at a Midwest hospital. This project …

Experiences Of Food Insecurity Among Single Mothers Pursuing Secondary Education, Amber Bernard

Walden Dissertations and Doctoral Studies

The number of single mothers continues to grow across the nation, and many are at a socioeconomic disadvantage. Little research focuses, however, on how single mothers describe their experiences of balancing motherhood, work, and pursuing higher education, all while undergoing food insecurity. Lazarus and Folkman’s transactional theory of stress and coping was used to formulate the research design. Semistructured interview questions were used to answer the question of how single mothers with food insecurity describe their experiences pursuing higher education. A generic qualitative research approach was utilized in this study. Interviews were conducted with 10 single mothers pursuing postsecondary education …

The formation of multinucleated syncytiotrophoblast (STB) through cell fusion of cytotrophoblast, also termed syncytialization, ensures the proper placental structure and functions. Nutrient insufficiency and inactivation of the mechanistic target of rapamycin complex 1 (mTORC1) in trophoblasts have been shown to enhance STB formation; however, the underlying mechanism remains elusive. Here, we showed that the deficiency of a mTORC1 downstream transcriptional factor, TFEB, significantly impaired STB formation in human trophoblasts and knock-out mice. TFEB conferred direct transcriptional activation of the fusogen ERVFRD-1 and thereby promoted trophoblast syncytialization. Additionally, TFEB expression positively correlated with the reinforced trophoblast syncytialization in human fetal growth …

Strategic Use Of Brachiaria Decumbens Pasture To Beef Heifers During Dry Season, E G. Cardoso, N F. Seiffert, J Marques Da Silva, V.P. B. Euclides, J M. Vieira

IGC Proceedings (1977-2023)

The main objective of this study was to evaluate a Brachiaria decumbens pasture, instead of a common rangeland, for zebu beef heifers during the dry season of the year as a means of anticipating the first calving age from four to three years of age, and so improve the production rate of the herd. Daily liveweight gains (DLWG) were analyzed for the effects of year and three stocking rates during the dry season (SR1=1.5; SR2=2.0 and SR3=2.5 head/ha). The main effect on heifers DLWG was the year (P<0.01), but SR was also important (P<0.05), mainly during the last half of the dry season when pastures are under severe constraints such as soil moisture deficit and low temperatures. The lowest SR presented the highest DLWG (0.204a, 0.174ab and 0.145b kg/head, respectively for SR1, SR2 and SR3), during the dry season. If climatic conditions are not exceptionally bad, heifer first calving occurs at 37 months of age when reared on B. decumbens.

Intensive Rotational Grazing Systems For Dairying In A Subtropical Environment: Animal, Plant, And Soil Responses, J H. Fike, C R. Staples, L E. Sollenberger, D A. Graetz

IGC Proceedings (1977-2023)

Forage species, stocking rate, and supplementation rate effects upon performance of lactating dairy cows were studied. Forage mass and nutritive value and nutrient concentration in shallow groundwater also were measured. Cows (n = 44) grazed bermudagrass (Cynodon dactylon) or rhizoma peanut (Arachis glabrata), stocked at 4.9 or 7.4 cows ha-1, and 2.5 or 4.9 cows ha-1, respectively. Pelleted concentrate:whole cottonseed (80:20) was offered twice daily post milking at 1 kg per 2 or 3 kg of daily milk production. Cows grazing rhizoma peanut produced more (P = .076) milk per day but had greater (P = …

Intake Of High Producing Holstein Cows Grazing Pasture Or Fed A Total Mixed Ration, E S. Kolver, L D. Muller

IGC Proceedings (1977-2023)

The ability of a pasture diet to support a high dry matter intake without supplementary feed was determined using 16 high producing Holstein cows. Cows (n=8) were adapted to an all-pasture diet by incrementally reducing the amount of total mixed ration (TMR) fed over four weeks. A control group of cows (n=8) remained in confinement and were fed a TMR. Performance of grazing cows differed significantly (P < 0.001) from TMR fed cows by intake (19.0 vs. 23.4 kg DM/d), milk production (29.6 vs. 44.1 kg/d), milk protein content (2.61 vs. 2.80%), liveweight (562.1 vs. 597.3 kg), and condition score (2.02 vs. 2.50). Results indicate that intake of good quality pasture is higher than previously estimated for high producing Holstein cows in the USA, but that milk production is 15 kg/d less than when cows are fed a TMR.

Cattle Production And Botanical Composition In Continuously Stocked Grass-Clover Swards, A Elgersma, H Schlepers

IGC Proceedings (1977-2023)

The performance of grass-clover mixtures was evaluated under cattle grazing, and the relations between grass variety, clover content and animal production were studied during four years at three locations. The prostrate diploid perennial ryegrass variety formed a dense sward with less clover and less weeds than the tetraploid or the erect diploid ryegrass varieties, which contained about the same amount of clover in the mixture. The ryegrass tiller density was lowest in the tetraploid. These differences between mixtures were not reflected in differences in animal performance or net energy production.

Sheep Production On An Annual And Perennial Pasture In Southwest Australia, P Sanford, J Gladman, L Cransberg

IGC Proceedings (1977-2023)

Sheep production on an annual and perennial pasture stocked at 11.5 dse/ha, was compared in a mediterranen environment at Manypeaks in Western Australia. The annual sward comprised of 48% subterranean clover (Trifolium subterraneum L.), 20 % annual grasses (Lolium rigidum Gaudin, Hordeum leporinum Link, Vulpia bromoides (L.) S.F. Gray) and 32% capeweed (Arctotheca calendula L.). The perennial sward was 19% kikuyu (Pennisetum clandestinum), 36% subterranean clover, 43% annual grasses (Lolium rigidum Gaudin, Hordeum leporinum Link, Vulpia bromoides (L.) S.F. Gray) and only 2% capeweed which was displaced by kikuyu. Both pasture types had similar growth …

Stocking rate of heifers was 5.9 animals ha- 1 averaging 230 kg. Heifers were rotated weekly and were on a 4 pasture rotation. Grasses were allowed a 3-wk regrowth period. Mean forage growth rate cycle-1 day-1 was not different (P>0.05) between grasses; however Florico and Florona yielded 8 and 21% more cycle- 1 than Florakirk. Mean herbage …

Pasture Heterogeneity Created By Grazing Of Cattle Biotypes With Different Body Size, M S. Cid, M A. Brizuela, M S. Aello, C Ferri

IGC Proceedings (1977-2023)

Cattle grazing leads to the generation of patches differing in forage quality and quantity even in virtually monoespecific pastures. This work assesses the effect of two biotypes of different growth rate and mature body weight on the patchiness of a tall fescue pasture. We analysed height, herbage mass by unit surface, and proportions of heavily and lightly utilized patches through a residual herbage mass gradient generated by both biotypes at four stocking rates from March to December. At the end of spring the residual herbage of paddocks grazed by the small biotype was more heterogeneous. The percentage of heavily utilized …

Forage Productivity And Animal Performance On Different Grass/Legume Pastures For Grazing Management, Sung Seo, Joung Kyong Lee, Dong Eun Shin

IGC Proceedings (1977-2023)

A grazing trial was carried out to determine the effects of different grass/legume pastures on forage productivity, nutritive value, and animal performance. The pasture mixtures were mainly orchardgrass (OG)+ladino clover(T1), mainly OG+alfalfa(T2), mainly perennial ryegrass+alfalfa(T3), and grasses alone (mainly OG, T4). The pastures were rotationally grazed 7 times with growing heifers in 1991 and 1992. The proportion rate of ladino clover in T1 mixtures rapidly increased from 21% up 54 to 68% during the grazing season. However, the rate of alfalfa in T2 and T3 ranged between 12% and 23%. The annual dry matter yield ranged from 9.19 in T4 …

Beef Production From Grazed Grass And Grass/Clover Swards, Edward G. O'Riordan

IGC Proceedings (1977-2023)

grazed grass (fertiliser nitrogen treated) and grass/clover swards, during two grazing seasons which extended from early-April until mid-November. Both permanent (Treatments A, B and C) and reseeded (Treatment D, E and F) swards were respectively stocked with 3000, 2500 and 2000 kg liveweight/ha in Spring using fifteen steers/treatment (liveweight = 570kg/head). There were small and generally non-significant treatment effects on final liveweight in both years, but heavier carcasses were observed on the reseeded swards (P<0.05). Clover based swards (Treatments B, C and E, F) produced heavier carcasses (P<0.05) than the nitrogen fertilised grass swards (Treatments A and D). Pasture production ranged from 7540 to 10,469 and from 6360 to 11,606 kg DM/ha in year 1 and 2 respectively, with highest yields being observed on the nitrogen fertilised treatment and on the reseeded swards.

Cattle Weight Gain And Sward-Animal Nitrogen Relationships In Grazed Hemarthria Altissima Pastures, L E. Sollenberger, G F. Lima, J F. Holderbaum, W E. Kunkle, J E. Moore, A C. Hammond

IGC Proceedings (1977-2023)

Limpograss (Hemarthria altissima [Poir.] Stapf et C.E. Hubb.) in vitro digestion is greater than most perennial grasses adapted to Florida. Weight gain of cattle grazing limpograss has been lower than expected due in part to low herbage N concentration. Experiments were conducted on limpograss pastures to assess N fertilization, overseeding of the legume aeschynomene (Aeschynomene americana L), and feeding of N supplements to cattle as means of overcoming this limitation. Greater N fertilization, overseeding aeschynomene, and supplementation (corn-urea mixtures) increased weight gain 0.30, 0.23, and 0.24-0.35 kg d-1, respectively, over control treatments. Herbage digestible organic matter:crude protein ratio …

White Clover Content In New Zealand Pastures Affects Milksolids Production, S` L. Harris, D A. Clark

During the first 10 day measurement period cows were fed ad libitum and during the second 10 days feeding was restricted to 75% of metabolisable energy requirement. Milk yields of cows fed 50 and 80% clover were 18% and 10% greater than for …

Pasture Species Effects On Animal Performance, T J. Fraser, S=J S. Rowarth, T L. Knight

IGC Proceedings (1977-2023)

Increasing concerns about food quality have resulted in investigations into the effects of different forage species on animal production and carcass quality. Pure species plots of high-endophyte ryegrass (Lolium perenne L.), white clover (Trifolium repens L.), chicory (Cichorium intybus L.), plantain (Plantago lanceolata L.) or lotus (Lotus corniculatus L.) were established and lambs grazed the species for 120 days during summer. Pasture species influenced growth rate, hot carcass weight, GR, wool growth, faecal egg counts, adult nematodes at slaughter, and sheep meat odour and flavour. Lambs grazing white clover, lotus or chicory outperformed those grazing …
