Effect of woodchip bedding during wet conditions on feedlot cattle productivity, behaviour and relative adrenal gland weight
Problems associated with muddy pens have been identified as some of the most serious animal welfare issues related to outdoor feedlot beef production, but there is relatively little work examining the use of woodchip bedding for lot-fed beef cattle under conditions of cold, wet, but non-freezing winters on soil under-bases. This study examined the effects of graded levels of woodchip on the performance and behaviour of feedlot cattle housed in wet pen conditions. Bos taurus steers (n = 300" 379.1 ± 24.1 kg) were blocked by weight and breed and randomly assigned to 30 10-steer feedlot pens provided with either no woodchip bedding (Control, n = 10) manure interface only, or 15 cm depth of woodchip bedding (W15, n = 10) or 30 cm depth of woodchip bedding (W30, n = 10). The steers were housed in these treatment pens for 109 days on a feedlot ration, and the pens were irrigated so that approximately 74 mm of total precipitation (irrigation + natural rainfall) fell onto the pen surface every 30 days. Temperatures were mostly <20 C maximum and 1 to 5 C minimum. Steers were weighed on five occasions. Animal position and posture in pen were recorded once a week over an 8-hour day-time period. Carcase characteristics were measured, and adrenal gland weights were recorded. Providing woodchip bedding increased liveweight gain (P < 0.001) and gain:feed (G:F, P = 0.012) after day 28, increased DM intake (DMI) after day 92 (P = 0.049), and increased carcase weight (P = 0.001) and dressing percentage (P = 0.023). There was no additional benefit of W30 over W15 for liveweight gain or DMI, but the benefit of W15 for G:F was lower than that of W30 by the end of the feeding period (P = 0.012). There were no effects of bedding on other carcase quality traits. Steers in Control pens utilised the front of the pen for lying and standing more than the W15 and W30 steers (P < 0.001) suggesting the steers in the Control pens perceived the front of the pen as less aversive, potentially due to increased drainage compared to rest of the pen and proximity to feed bunk. Adrenal gland weight/kg and carcase weight tended to be higher in the Control treatment group than the W30 steers (P = 0.077). This research has demonstrated that for a 109-day feeding period in cold, wet conditions, steer performance and welfare can be improved by providing a minimum of 15 cm woodchip bedding.
Quantitative Skills in the First Year Science Curriculum: Reflections on a Collaborative Journey
An OLT Extension project: 'Acquiring and applying a shared meaning of quantitative skills (QS) across core first year science units with a focus on distance education', commenced this year. One of its aims was to establish an ongoing cross-disciplinary collaboration among scientists, mathematicians and statisticians at a regional university to enhance student learning of QS in interdisciplinary contexts, with a focus on distance education. The success of this project depends on academics from the various disciplines appreciating the need for a collaborative approach, and agreeing to join the facilitator(s) on the journey. This paper will present initial results from the collaborative processes taking place as part of the project but will also examine the complex web of interactions, and formal and informal collaborations that led to the development of this inter-disciplinary, cross-school project.
Nature and level of NTFP reliance: a case study in the buffer zone of Cat Tien National Park, Vietnam
There is growing evidence that collection of non-timber-forest products (NTFPs) remains an essential part of livelihoods for people living near protected areas in developing countries. This study examined the nature and level of livelihood reliance of households on the collection and use of NTFPs and alternative income streams for three ethnic groups (Chau Ma, Stieng and Kinh) in a village in the buffer zone adjacent to Cat Tien National Park, Dong Nai province, Vietnam. Household surveys (n = 150) and key informant interviews (n = 10) were conducted to collect data on forest usage, household socio-economy, and collection of NTFPs. About one-third of Chau Ma and Stieng households had a high reliance on NTFPs, while Kinh households having no reliance on NTFPs for their livelihood. The dependence on NTFPs for Chau Ma and Stieng people was a result of limited opportunities for other livelihood options due to a complex set of factors, including among others low education levels and imposed fundamental changes to their traditional livelihoods. For Chau Ma and Stieng people struggling to adjust from a subsistence forest-based livelihood to living outside the forest, around 42% continued to visit the forest for cultural reasons including traditional food and ceremonies, albeit at low to moderate levels (63%). It is proposed that government authorities acknowledge the livelihood role for local people of low-level traditional use of NTFPs. In addition, for those people who are highly reliant on NTFPs, alternative livelihood strategies should be developed further, to better engage their local knowledge and skills in the co-management of the Park forest.
Addressing the Diversity of Student Mathematics Preparedness for Engineering Surveying: A Proposal for a Technology Supported Learning Scaffold
This paper examines the diversity of mathematics preparedness of students undertaking study of engineering surveying taught at the University of New England (UNE). As UNE is a relatively small institution, this subject is taught at both undergraduate and postgraduate level and as part of a wide range of courses from Engineering, Environmental Science and Geographical Information Systems to Archaeology. As expected from such a diverse group of degree programs, the mathematical background of students is quite variable. As a teacher this is very challenging, so it is proposed to use technology to scaffold students' learning of the necessary mathematics. This will involve the provision of screencasts that will allow students to develop the necessary skills in a self-paced manner.
Partnership approach to topic selection of first year university assessments in sustainability
Engaging engineering and agriculture students to sustainability principles has changed from a marginal issue to mainstream with time. Current professionals in engineering, agricultural and environmental sciences require a clear understanding of the principles of sustainability; supported by accredited bodies such as Engineering Australia. At this regional university these students are required to complete two units of study in sustainability of rural environment, the first of which will be discussed in this paper, which outlines the unique Australian environment. To understand the concept of sustainability, students need to see the relevance in their lives and chosen career. Therefore care needs to be taken in the choice of topics for assessments such as 1500 word essay; and in this article how these topics are chosen will be discussed. This article will outline the process of topic selection that follows a partnership approach between a lecturer, first year advisor and librarian. Placing such importance, on the sustainability of Australia in first year of such a diverse group of students shows innovation in the higher education sector. These degrees that fall within the School of Environment and Rural Science whose aim it is to save the planet, feed the world.
Development and Application of a Distributed Leadership Framework to the Curriculum Mapping of Quantitative Skills in First-Year Undergraduate Agriculture Degrees
Quantitative skills (QS), the ability to use mathematical and statistical reasoning in context, are considered essential threshold learning outcomes in Australian university agricultural courses (degrees). Curriculum mapping can be used to determine how the existing curriculum fosters the development of QS, and identify where opportunities for skills development are missing in the curriculum. To address the challenges of curriculum mapping this paper describes the development and application of a modified distributed leadership model based on the merging of Kotter’s eight steps for structural change (2014) and Jones, Hadgraft, Harvey, Lefoe and Ryland’s framework for distributed leadership (2014). Distributed leadership is built on the foundations of change theory, moving beyond the traditional leadership boundaries and has been increasingly used in higher education. This case study demonstrates how distributed leadership has been used successfully in determining the graduate level QS and driving the mapping process for the first-year curriculum. Curriculum maps showed when the QS were taught, practiced and assessed across 10 science degrees, including three agriculture degrees, at a regional Australian university. As a result, holistic curriculum changes were flagged with the aim of enhancing QS development for both on campus and distance learning students.
Influence of acute mild winter conditions on the productivity of feedlot cattle: An Australian perspective
The impact of cold stress on feedlot cattle has received limited investigation in temperate climates. However, cold stress has been found to impact cattle welfare and production in temperate climatic conditions, where ambient temperature (TA), precipitation, relative humidity (RH), wind speed (WS) and solar radiation (SR) all influencing apparent temperature. While there are many indices to quantify cold stress in cattle, there are limited indices that directly relate to cattle and account for all the interactions between climatic variables. This makes cold stress difficult to quantify, with on-cattle measures such as core body temperature and shivering difficult metrics to obtain in feedlot cattle. Moreover, individual cattle will react differently to cold conditions based on their production, age, sex, coat characteristics (colour and type), breed and nutrition. While cold stress can be difficult to measure, the production status, behavioural and physiological effects of cold stress have been identified, but generally under what could be considered as extreme cold stress events. Similarly, while mitigation strategies such as shelter, bedding and windbreaks have been investigated, limited information is available surrounding their usefulness in temperate climates. Further research is needed to fully investigate the effects of cold stress and how to mitigate those effects in feedlot cattle under conditions, such as those found in Australia.
Perceptions and Applications of Information Literacy by First Year Applied Science Students
This paper examines where students prefer to find information, and then matches survey results with students' assignments. Surveys showed that half the surveyed students used library databases (e.g. ProQuest) as their first preference to locate scientific information; however, of these students, one third did not have any journal articles cited in their assignment. Furthermore, of those students with no journal articles cited in their reference list, 65% claimed to feel comfortable using library databases, against a figure of 100% who felt comfortable using Google Scholar. This indicates a mismatch between students' expressed preferences and their actual ability to locate, evaluate, and include refereed journal articles in their assignments.
The Performance of Alternative Livelihood Initiatives on Local Livelihoods and Forest Conservation Management - A Case Study in Talai Commune, Dong Nai Province, Vietnam
Protected forest areas worldwide are located close to forest dependent communities that continue to use forest resources for their livelihoods to varying extents. With these areas designated as protected areas it prevents local people from practising their traditional income-generating or subsistence activities that rely on access to forest areas. Although governments view protected areas as a measure for forest conservation, they pose a number of key challenges to local people's livelihoods.
In a number of developing countries, including Vietnam, the use of forest resources in protected areas have presented a threat to forest conservation outcomes. A satisfactory resolution to the tension between livelihoods and biodiversity conservation objectives in protected areas is an ongoing challenge for governments and local people living near protected areas.
Cat Tien National Park, a protected area in Dong Nai Province, Vietnam is well-known for its diversity of flora and fauna and offers a noteworthy case study. One of the issues in Cat Tien National Park is the practice of collecting non-timber forest products that is considered widespread, despite it being illegal under the protected status of the Park. Achieving forest conservation goals under these circumstances, even if extraction levels were low, appears to be a challenging task. In order to address livelihood challenges, governmental agencies, and non-governmental organisations have attempted to engage local people in alternative livelihood initiatives. These initiatives commonly seek to provide new income sources as a substitute for earnings from traditional livelihood practices, thereby reducing extraction pressures on the Park. These livelihood initiatives have been active in the last thirteen years.
The aim of this thesis is therefore to examine the performance of two alternative livelihood initiatives (the Talai Ecotourism Venture and the Forest Protection Team (FPT)) on local livelihoods for those ethnic groups living in close proximity to the Park and associated effects on forest conservation management goals. The research provided insights into the participation of local people in decisions about the management and conservation of forest resources in their role as FPT members. It also attempts to draw lessons that can be applied to alternative livelihood initiatives elsewhere in Vietnam and other developing countries. A case study approach with a mixed method has been employed in this study. Household surveys (n=150) of three ethnic groups (Chau Ma, Stieng and Kinh) and key informant interviews (n=36) were conducted to collect data on a range of aspects, including: household demographics, forest usage, and local views on the impact of the two alternative livelihood initiatives on their livelihood and perception of forest conservation. The key informants were interviewed at length about their roles, responsibilities, the quality of the local participation, and evaluation of the effectiveness of the two alternative livelihood initiatives on local livelihood and forest conservation. Field research findings were supplemented and triangulated with participant observation activities to gain insight into the physical, social, cultural, and economic aspects of the case context.
About one third of Chau Ma and Stieng households had a high reliance on NTFPs, while Kinh households had no reliance on NTFPs for their livelihood. The dependence on NTFPs for Chau Ma and Stieng people was a result of limited opportunities for other livelihood options due to relinquishing agricultural land and low education levels. For Chau Ma and Stieng people struggling to adjust from a subsistence forest-based livelihood to living outside the forest, around 41% continued to visit the forest for cultural reasons, but at low to moderate levels (63%).
A significant finding of the study is that the benefits of the alternative livelihood initiatives did not extend to the whole community and were focused largely on those ethnic minorities of Chau Ma and Stieng directly involved in the initiatives. Further, for the two alternative livelihood initiatives, the direct participants gained the greatest benefits either through employment, access to Village Development Fund, or greater access to NTFPs.
The study has also found that current livelihood initiatives have not been effective due to limited local participation in decision-making processes, and minimal interaction with local people outside the initiatives. Specifically, the governance of these initiatives was not aligned with communitybased principles. The one-way information sharing, and top-down decision-making led to the ethnic minorities assuming only a passive role in the process for the two alternative livelihood initiatives.
In addition, local members of both livelihood initiatives did not receive the training or support they required to effectively carry out their responsibilities. The results of the case studies also showed that there was a lack of responsiveness from key governing authorities such as the Private Company, Talai Forest Station, Park Board to variations in ethnic groups' socio-economic status, and levels of literacy. As a whole, such deficient governance arrangements and processes prevented the initiatives from achieving their goals and engaging with the broader community. In addition, evidence suggests that the Talai Ecotourism Venture and the Forest Protection Team initiatives have not led to a substantial change in local people's awareness of the importance of forest conservation and lessening the pressure on forest resource extraction as expected.
These findings demonstrate the need for better governance, which provide stakeholders with the ability to demonstrate their understanding and fulfil their responsibilities independently. A greater level of accountability and transparency in benefit sharing mechanisms such as Village Development Fund (Talai Ecotourism Venture), and Forest Protection Team reporting is also required for ensuring greater community participation and empowerment. Another important implication of improved accountability is for a more effective relationship between government, private enterprise and local people in decision making and empowering them in their roles. Finally, the findings also highlight the significance of capacity building for various stakeholders so that they can develop skills and knowledge required to carry out decision-making responsibilities in ecotourism and forest management. Most importantly, alternative livelihood initiatives need to be designed and implemented with sensitivity to the local cultures otherwise; they can limit potential equality and increase obstacles to local people's participation and decision-making. Thus, it is recommended that Indigenous knowledge should be recognized and incorporated into initiatives for protecting and managing forest resources.
Using the Results of Teaching Evaluations to Improve Teaching: A Case Study of a New Systematic Process
This article describes a new 14-step process for using student evaluations of teaching to improve teaching. The new process includes examination of student evaluations in the context of instructor goals, student evaluations of the same course completed in prior terms, and evaluations of similar courses taught by other instructors. The process has steps to help maximize instructor motivation as well as to help identify good targets for improvement. The article describes as an initial case study the experiences of academics in three disparate fields in using the new process. This initial use of the process led to deeper reflection than usual for the instructors and to ideas for ways to improve their teaching. The results indicate that the new process holds potential as a systematic way of using student numerical ratings and comments to produce plans for improvements in teaching.
