- ItemIntegrating EndNote from download to research report for distance masters students(Flexible Learning Association of New Zealand, 2018) Laven L; Murray F; Baxter K; Hill KIn order to complete a Masters, students are required to demonstrate a high level of skill in the completion of an original research activity, which relies heavily on information literacy. The Masters of Veterinary Medicine (MVM) is a 120 credit online distance programme comprising of four or five 15 credit taught online courses (15 credit), and a research report (45 or 60 credits). The MVM team identified a need to incorporate the bibliographic software tool EndNote into the online taught courses. Prepopulated compressed Endnote libraries were inserted into the Moodle platform of each taught online course alongside an Endnote instruction forum. Endnote skills or tasks were also provided throughout the online classroom (Moodle) and written materials.
- ItemMeasuring hoof horn haemorrhage in heifers: A history.(Elsevier B.V., 2024-06-27) Laven R; Laven LUnderstanding the aetiology and pathogenesis of claw-horn disease (CHD) is essential for developing prevention/treatment programmes. Haemorrhages in the hoof horn (i.e. white line/sole haemorrhages) are an important part of the pathogenesis of CHD, being precursors to and predictors of lesions such as white-line disease and sole ulcer. Understanding haemorrhage development can provide useful information about the aetiology and pathogenesis of CHD. The development of hoof horn haemorrhages is best studied in cattle without previous claw-horn damage, as previous history of damage can markedly alter the hoof's response to stressors. Since the early 1990s, many prospective studies of the risk factors associated with CHD have been undertaken in late pregnant and early lactation heifers, which have a low risk of having had CHD but which are exposed to the same risk factors as lactating cows. Those studies have used a range of methods to assess hoof horn haemorrhages, with the principal focus, particularly initially (but also more recently), being on measuring lesion severity. However, as the science developed it became clear that measuring lesion extent was also important and that combining severity and extent in a single measure was the best approach to assess hoof horn haemorrhages. Studies of hoof horn haemorrhage in heifers have significantly increased our understanding of CHD, demonstrating the importance of housing and the relative lack of importance of post-calving nutrition. Most importantly, they have shown the importance of parturition as a risk factor for CHD, and how parturition interacts with other risk factors to accentuate their effect. The use of such studies has decreased in recent years, despite recent research showing that we still have much to learn from prospective studies of hoof horn haemorrhages in heifers.
