Abstract:

Changes in animal production over the last several decades, whilst enabling a reliable supply of animal-based protein, have caused concern among consumers and stakeholders within the food industry regarding the impacts of farming on animal welfare, the environment, and human health. Many people consider animal welfare a public good, yet the role of government intervention to protect it is limited and therefore market forces are currently acting as the major driver of improvements to welfare standards. It is important to understand consumer attitudes towards animal welfare and whether concerns

Abstract:

This thesis describes a methodology of Precision Livestock Farming, to investigate animal health and welfare, through the monitoring of animal behaviours and vocalisations using image and sounds analysis instead of the visual observation methods. The main purpose of PLF is to improve the production efficiency, increasing animal and human health and welfare, through the application of advanced information and technologies, to control the entire production process. This thesis was particularly dedicated to the importance of using new technologies and methodologies to improve animal health, welfa

Abstract:

The livestock production main purpose is to satisfy the customer requirements at a price that enables the producer to make a profit. This trend moved the farm concept to the new control and monitoring technology system to support its operations. This new idea of the farm takes the name of “Precision farming technology” (PFT). The objective of the researches described in this thesis is to study and evaluate different type of technologies used in the PFT. To achieve this objective, six different trials were done; in the first trial, it was evaluated the use of an electronic system for automatic

This thesis is a sociological exploration of how people involved in commercial and hobby livestock production, in Northeast Scotland, make sense of their relations with livestock, from birth to slaughter. I carried out an ethnographic study that combines fieldwork and unstructured interviewing to elicit how mart workers, auctioneers, vets, farmers, stockmen, hobby farmers and slaughter workers regard and interact with livestock. Although livestock are the raw materials of production, I show that the commodity status of livestock is variable and that people's relationships with livestock are co

Greasy fleece weight also increased with increasing age and plane of nutrition but fibre quality declined since the increase in mass was achieved by means of increased fibre diameter with no effect of age or plane of nutrition on the fibre elongation rate.

Abstract:

Agricultural intensification has created a great deal of public skepticism. One major area of concern has been the welfare of animals. This thesis explores a diversity of issues centering on perceptions of the welfare of animals. Chapter 1 begins by reviewing the literature on theories of welfare in both humans and animals. After highlighting several challenges for contemporary theorizing about animal welfare, I conclude that philosophical progress on these problems can be enhanced via experimental research.

The intensification of animal production has been associated with an increased incidence of production diseases, which can negatively impact upon farm animal welfare (FAW). While there is considerable research focused on public attitudes towards improved FAW, it is not clear whether this relates specifically to a reduction in diseases related to animal production systems. This research therefore seeks to establish public attitudes towards FAW with a specific focus on production diseases, and whether the incidence of diseases and interventions associated with these represent a barrier to their
