Pastures And Pasture Management For High Animal Production In New Zealand, R W. Brougham, G P. Cosgrove

IGC Proceedings (1977-2023)

Limits to pasture and animal production from perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) pastures have been studied in systems experiments with fattening dairy beef bulls in the lowland Manawatu region of New Zealand. At high stocking rates the management system utilizes peak spring pasture growth and provides sufficient herbage for animals during periods of low growth in self contained, no conservation farmlets. High animal production of approximately 1000 kg of carcass meat/ha annually has been achieved. Accumulation of pasture reserves in autumn through long rotations and reductions in grazing pressure in summer through slaughter of fattened animals …

Mosaic Grazing - Animal Selectivity In Tropical Savannas Of Northern Australia, J J. Mott

IGC Proceedings (1977-2023)

In set stocked, heavily grazed, unburnt, native grass/sown legume pastures in the tropical savannas of northern Australia, animals were found to graze very selectively. This contrasts with the more uniform light grazing usually occurring in the extensive, lightly grazed native grasslands which are normally burnt annually. Once heavy selective grazing of an area was initiated, this grazing pressure was maintained, while ungrazed areas grew rank and unacceptable. Although three different sized paddocks were used to give different stocking rates, the area heavily grazed was the same at all stocking rates. In unfertilised paddocks, plants died within two years when selectively …

Influence Of Herbage Mass And Structure Of Warm-Season Grass Ingestive Behavior Of Grazing Cattle, T.D A. Forbes, S W. Coleman

IGC Proceedings (1977-2023)

An experiment was carried out to investigate the effects of herbage mass and height on cattle ingestive behavior and herbage intake, when grazing Asiatic bluestem (Bothriocloa spp.) swards. Three levels of herbage mass were maintained under continuous grazing, corresponding to 1.8, 2.0 and 4.4 t dry matter/ha. Estimates of diet in vitro organic matter digestibility, rate of biting, grazing time and intake per bite were used to calculate digestible organic matter intake (DOMI). Differences in herbage mass led to significant differences in grazing time, intake per bite and DOMI but not in diet digestibility or rate of biting. The …

Selection, Mastication, And Digestive Tract Response Of Cattle To Plant Canopy And Composition, D S. Fisher, K R. Pond, J C. Burns, R D. Mochrie, D H. Timothy

IGC Proceedings (1977-2023)

The relationship between pasture sward structure and animal intake of digestible dry matter is not well understood. To aid in developing an understanding of the plant-animal interface, flaccidgrass (Pennisetum flaccidum Griseb.) and switchgrass (Panicum virgatum L.) swards were harvested and stratified by cutting them into 5-cm layers. Strate began 5-cm above the soil and continued to the extended height of the sward. The strate were separated into leaf blade, stem, and dead material. Samples were analyzed for dry weight and in vitro dry matter disappearance {IVDMD). Esophageal sample analysis showsd steers consumed leaf material even in swards with …

The Role Of Sward Adaptations In Buffering Herbage Production Responses To Management Manipulation, S A. Grant, J King, G T. Barthram

IGC Proceedings (1977-2023)

The aim of this study is to improve understanding of sward responses to grazing manipulation so that objective guidelines for management may be provided. Rates of growth and senescence per tiller, tiller population densities and the photosynthetic efficiency of the sward canopy were measured at intervals on Lolium perenne dominated swards under contrasting management regimes involving steady-state and controlled fluctuations in sward conditions. The results suggest that the combination of changes in tiller populations, sward structure and photosynthetic efficiency and in the balance between growth and senescence per tiller act as a buffer such that net production varies little within …

Sward Utilization In Warm Season-Cool Season Grass Grazing Systems In The North-East United States, R L. Reid, G A. Jung

IGC Proceedings (1977-2023)

Grazing and behavioral trials were run over a 4-yr period to investigate use of warm season (WS) range grasses in management systems for beef cattle on marginal hill land. Grasses tested were switchgrass (Panicum virgatum L.), big bluestem (Andropogon gerardii Vitman), Caucasian bluestem [Bothriochloa caucasica (Trin.) C.E. Hubb.], indiangrass [Sorghastrum nutans (L.) Nash] and Plains bluestem [B. ischaemum (L.) Keng var. ischaemum]. The grasses were originally planted in pure stands and evaluated as summer pasture for yearling heifers following spring grazing on native bluegrass (Poa pratensis L. )-white clover (Trifolium repens L.). Other systems tested …

Mixed Grazing By Sheep And Cattle: Effects On Herbage Production And Utilization, J Hodgson, J C. Arosteguy, T.D A. Forbes

IGC Proceedings (1977-2023)

Two experiments were carried out to examine the effects of mixed stocking with cattle and sheep on aspects of herbage production and utilization from sown swards. On plots grazed down over three days both sheep and cattle tended to concentrate their grazing activity progressively on areas of sward previously grazed by the opposite species. Cattle were shown to be much less tolerant of cattle dung than of sheep dung, but sheep were relatively tolerant of both sheep and cattle dung. In a second study sheep and cattle were grazed alone, or in combination, on swards maintained at similar surface heights …

Animal Production Of Fattening Young Steers And Beef Cows By Precursor- Follower System On Two Pasture Types, Y Takimoto, K Nishimura, H Takeda, E Tsuneishi, T Suyama, T Mitamura, S Murasato

IGC Proceedings (1977-2023)

Animal productions were compared on two pastures, i.e. PW pasture (perennial ryegrass-white clover dominant pasture) and PO pasture (perennial ryegrass-orchardgrass dominant pasture), through precursor-follower system using feeder steers and beef cows. The experiment was carried out in 1983 and 1984. After close of grazing feeder steers were fattened for 6 or 7 months, then the carcass characteristics were examined. Feeder steers used in the experiment 1983 were born in spring and grazed for 2 seasons. And in the experiment 1984 steers were born in spring and in fall. They grazed for 2 seasons and 1 season, respectivery. By the precursor-follower …

Relations Between Nitrogen Fertilization, Herbage Production And Milk Yield, E A. Lantinga, L T'Mannetje, H Schlepers

IGC Proceedings (1977-2023)

The response to N-fertilizer of animal output and of herbage production was compared. There appeared to be no difference in the responses to applied nitrogen between intensive continuous grazing and weekly cutting in the range of 300 to 500 kg N/ha/yr. It is hypothesized that the response to applied nitrogen in a continuously grazed sward is mainly determined by the intensity of grazing and that the benefit from nitrogen circulation through excreta has little meaning for the pasture as a whole.

Modelling Grazing Intensity Studies, David I. Bransby

IGC Proceedings (1977-2023)

Grazing intensity models have traditionally related animal production per head and per ha to stocking rate. The value of such models is limited by the omission of pasture information. In this paper the relationships between average daily gain, grazing days and standing herbage are used to develop models relating animal production per ha to standing herbage. These models can also be extended by relating changes in their parameters to additional quantifiable variables, or by using them in economic models to express profit per ha in terms of standing herbage.

Grazing As A Part Of Agroforestry, Harold F. Heady

IGC Proceedings (1977-2023)

Multiple use of land by the small landholder for food crops, trees and animals, often called agroforestry, holds great promise for aiding people near poverty in developing countries, but new forages and techniques of management must be developed.

An Interdisciplinary Approach For Increasing Yield And Improving Quality Of Forages, J R. Wilson

IGC Proceedings (1977-2023)

The contribution of some basic plant disciplines, principally physiology and histology, to the improvement of pasture yield and quality is discussed. Studies of temperate pasture grasses have identified several sources of loss of potential yield and have provided selection criteria for increasing yield. Integration of this physiological research with studies of forage consumption on the same pastures is proving a valuable inter- disciplinary approach to defining management options for maximising pasture and/or animal productivity. In tropical grasses, research towards increasing total dry matter yield is perhaps unwarranted but there is need for more co-operative studies involving plant and animal scientists …

When Creative Practice Becomes Research, James Kelly

Staff Scholarship - Australia & Dubai

This seminar examines approaches to practice and research within an academic context, with particular reference to the academic scholarship framework at SAE University College. It introduces distinctions between creative practice and research, demonstrating how disciplinary practice may be transformed into recognised scholarly output when it is contextualised within a theoretical framework, critically reflective, and disseminated for peer engagement.

Drawing on methodologies by Candy (2006), Skains (2018), and Barrett (2019), the presentation outlines methodological models for Practice-as-Research (PaR), Practice-Based Research (PBR), Practice-Led Research, Research-Led Practice, and hybrid approaches. It highlights the iterative and open-ended character of creative research processes, in which …

Bandung And The Future Of Africa’S Pasts, Rabiat Akande, Olufemi Elias

Articles & Book Chapters

The idea of decolonization that animated the spirit of the 1955 Bandung Conference continues to power imaginations of an alternative to the world Bandung inhabited. In this essay, we look upon Africa from Bandung, and simultaneously from Africa to Bandung, to recover an “otherwise”—a seeing of the future from Africa’s pasts. In the future envisioned in Bandung and beyond, flag independence was regarded as the first stop in the project of decolonization.1 The conference was to provide both “guidance to mankind … [on] the way which it must take to attain safety and peace” and “evidence that Asia and Africa …

Examining Children’S Intuitive Understanding Of Mechanical Systems With A Gears Assembly Task, Nicole Taboada

Theses

Children’s causal reasoning about machines and their components is crucial for acquiring knowledge about science and math. Mechanistic understanding involves knowing how parts can be effectively connected to work together as a functional mechanical system. Little is known about how children’s understanding of mechanical systems develops across the lifespan. Legare and Lombrozo (2014) developed a gears assembly task to assess children’s understanding and learning of mechanics but did not track this skill across ages. The present study adapted the gears assembly task to measure mechanistic understanding in children between the ages of 4 to 11 years and adults. The goal …

Decarbonization Is Happening In U.S. Higher Education, But Carbon Neutrality Goals Alone Are Not Delivering It, Alexander R. Barron, Nubraz F. Khan, Greta Anesko, Emma S. Larsen, Junwen Ding, Shey P. Sanges, Aaron L. Strong

Environmental Science and Policy: Faculty Publications

Carbon neutrality emerged as an overall framework for climate action several decades ago, with the assumption that institutions would follow a carbon management hierarchy - reducing their own emissions (i.e. decarbonization) and relying on high-quality offsets to address any residual emissions. In practice, offsets and other accounting-based emissions reductions have often dominated both discussion and action. However, sector-wide studies examining the balance between decarbonization and offsetting have been limited. Here, we examine 23 U.S. Higher Education Institutions (HEIs) that have declared carbon neutrality and contrast their direct (Scope 1) greenhouse gas emissions reduction efforts with a broader universe of U.S. …

Clinical Course And Treatment Outcomes In Solid-Basaloid Adenoid Cystic Carcinoma Of The Breast: A Systematic Review And Case Report, Stephanie Kim, Kyle Sheth, Xiaoying Yu, Laura Porterfield, Elizabeth M Vaughan

Faculty, Staff and Students Publications

Background: Adenoid Cystic Carcinoma (ACC) is a rare, indolent subtype of triple-negative breast cancer, accounting for < 0.1 % of cases. The solid-basaloid subtype (SBACC), comprising approximately one-quarter of breast ACCs, has a poorer prognosis. While ACC is typically managed with surgery and is chemo-resistant, SBACC is more aggressive and often treated with chemotherapy and, more recently, immunotherapy-though supporting evidence remains limited.

Aim: To assess clinical characteristics and treatment outcomes of SBACC of the breast.

Methods: This study presents a case of breast SBACC and a systematic review of five databases (inception-September 10, 2024). Eligible studies reported clinical course, treatment, and outcomes. Exclusions included duplicates, non-SBACC focus, animal studies, and those lacking clinical or with only pathological data. Descriptive statistics were used for binary and categorical variables. Risk of bias was assessed using JBI tools, following PRISMA 2020 guidelines. The review is registered in PROSPERO.

Height And Phytotelm Size Affect The Invertebrate Communities Of Epiphytic Bromeliads In The Amazon Rainforest, Xaali O'Reilly-Berkeley, Alex Pazmiño-Palomino, Andrea Hidalgo-Cárdenas, Sofía I. Trujillo-Regalado, Hannah Mossman, Jennifer K. Rowntree, Richard F. Preziosi

School of Biological and Marine Sciences

Tank bromeliads are found in rainforests across the Neotropics and harbour diverse invertebrate communities between their leaf axes. Various factors influence the invertebrate species richness and differences in composition in bromeliad phytotelmata, most notably, habitat size. However, there has been little work on invertebrate communities in bromeliads in western Amazonia or at different heights in the canopy. We collected 63 epiphytic bromeliads (Aechmea hoppii (Harms) L.B.Sm, A. nidularioides L.B.Sm) on the eastern edge of the Tropical Andes Biodiversity Hotspot in Ecuador and explored which biological and physical variables explained the differences in invertebrate composition among bromeliads. We extracted a total …

The Big Bang Theory’S Blurred (Tele)Vision Of Scientific Ethics: Some Thoughts For Educators Who Want To Change The Channel, Lee-Anne Broadhead, Sean J. Howard

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This article investigates the way the popular American television program The Big Bang Theory represents the pursuit of scientific knowledge and reflects on the cultural and educational implications of the show’s contradictory problematization and valorization of the reductionist method at the core of modern Eurocentric science. Drawing on story-lines relating to military research, animal experimentation, and pharmaceutical drug trials, we consider the show’s precarious balance of implicit critique (the consistent exposé of systematically violent, often unethical research) and overt celebration (the presentation of science as “cool,” and its practitioners as flawed but endearing). This tension, we argue, enhances the show’s …

On The Road To A Better Life? Rural Road And Economic Development In Albania, Santosh Gautam, Ermal Llirjani, Patralekha Ukil

Faculty Research, Scholarly, and Creative Activity

This study evaluates the impact of investment in rural roads on household welfare in Albania using a difference-in-differences method. We find that treated households experienced a 35-percentage point increase in the road quality and reduced travel times to the nearest motorable roads. Land and housing values rose significantly, and household heads were less likely to be unemployed, with a shift toward self-employment. While household income did not change significantly, consumption—particularly on non-food items—increased. These findings highlight the welfare-enhancing effects of improved connectivity and suggest that rural infrastructure investments can promote local economic activity. Policymakers should consider pairing road upgrades with …
