Abstract:

To establish the prevalence of diseases in sheep flocks in North-east Scotland responsive to the application of preventative measures which may be incorporated in flock management plans. A survey of a sample of commercial sheep flocks was carried out to ascertain management and marketing practices. A critical assessment was made of the 'Flock Diary' 'Detailed' and 'Daily' Lambing Diaries produced by the Meat and Livestock Commission and their use. A mastitis survey showed an overall incidence for acute severe and chronic mild mastitis of 1.5% and 4.2% respectively. Orf was a particularly impor

Abstract:

This thesis presents an Actor-Network Theory (ANT) inspired analysis of sheep scab in Scotland. Sheep scab is caused by scab mites, and it has a long history in terms of its legislation and available treatments in the UK. In 2010 it became a notifiable livestock disease again in Scotland. Even though sheep scab is studied by natural scientists and economists, it remains unclear how scab is understood by sheep practitioners. This means that the stories, practices and knowledges of sheep practitioners who work at the forefront of sheep scab (in terms of its recognition, diagnosis, treatment and

The objective of this thesis was to better understand the epidemiology of caseous lymphadenitis (CLA) and its economic effects on the Australian sheep industries. The work also sought to apply this knowledge to better understand how to control the disease in Australian sheep flocks. The occurrence of CLA in some other species, as a comparison to CLA in sheep, is described in the literature review. However a comprehensive review of research on CLA in all livestock species is not needed to meet the aims of the thesis. The research used serological tests developed in the 1970s and 80s to exami

Abstract:

Facial eczema disease (FE) is a secondary photosensitisation disease of ruminants caused by exposure to the mycotoxin sporidesmin. Resistance to FE has a significant genetic component and previous research has included a whole genome scan and investigation of candidate genes. The aim of this study was to use multiple approaches to identify genes associated with resistance to FE. ABC transporters have been considered as putative candidate genes for FE since the yeast ABC transporter, PDR5, was found to modulate sensitivity to sporidesmin in Saccharomyces cerevisiae.

The aim of this study was to investigate the characteristics of an outbreak of foot-and-mouth disease (FMD) in Greece during 1994. This epidemic suggested that under certain circumstances transmission of foot-and-mouth disease virus (FMDV) may not be as efficient as is classically thought. Here, analysis of field data from the epidemic has shown that conditions at the source of the epidemic may have provided an initial amplification of the force of infection, enabling the virus to cause a limited number of outbreaks elsewhere. These favourable conditions included a high density and large numbe

The ability of different 'M. ovipneumoniae' strains to grow in various media adaptations, where PPLO broth had been replaced by a vegetable protein source was investigated.

Abstract:

Merino sheep are the most numerous domestic livestock in Australia and feral goats are wide-spread and locally abundant in many of the regions where sheep are grazed. Foot and mouth disease (FMD) is a disease of ungulates that causes severe economic hardship to countries where outbreaks occur or where it has become endemic. In India, Africa, Greece and recently the United Kingdom and Eire, sheep and goats have been implicated in the spread and maintenance of FMD. In Australia, there are contingency plans (AUSVETPLANS) for dealing with an outbreak of FMD. Included in those plans are strategies

Abstract:

Expression of the cellular prion protein (PrPC) from the PRNP gene is crucial for the development of a group of fatal neurodegenerative disorders called prion diseases. During prion infection a misfolded protein homologue of PrPC, PrPSc causes further misfolding on interaction with native PrPC molecules. PrPSc is highly resistant to proteinase K and aggregation of this protein is considered a hallmark of infection. Sheep are considered a model of natural infection and susceptibility to scrapie in sheep is defined by polymorphisms in the PRNP gene. It is still not fully understood how these pol

Abstract:

Over the last 60 years, grass tetany has been recognised as a significant lethal condition in sheep and cattle.Outcomes from this study include documentation of the likely precursors to grass tetany, ways to recognise these precursors, and long term practices that will enable producers to minimise livestock deaths. The benefit of this research to beef producers is that the environmental circumstances thought to be associated with outbreaks of grass tetany have been identified, along with remedial action that can be taken to prevent deaths occurring.Recommendations to industry on best practice
