Abstract:

One of the main deterrents against group-housing systems of dry sows is the aggression between animals and the expensive designs necessary to prevent this. This is related to the low feeding level accepted in practice. The low level of feeding is also linked to the occurrence of stereotypies which are generally accepted as an indication of poor welfare. An ad libitum feeding system which does not result in excessive intake and concomitant problems of obesity, might improve sow welfare and have economical advantages in reducing capital cost. Suitable diets might be high-fibre diets. High inclus

Abstract:

Experiments were conducted to examine the impact of high milk yields on the behaviour and welfare of dairy cows. A preliminary study determined the social interactions existing within a group of 60 cows from which sub-samples of 20 high and 20 low yielding cows, that were not observed to interact with each other, were identified. These cows were used to examine the behavioural strategies employed by dairy cows coping with increased nutritional demands from milk production. Grazing time significantly increased with milk yield, consequently reducing lying time. A second study measured the appeti

Abstract:

A programme of study was undertaken to assess the welfare status of multiparous gestating sows housed in dynamic groups in a straw yard and fed by electronic sow feeders (ESF). Comparison of production figures from the Seale-Hayne herd with those nationally confirmed its status as a typical commercial unit. In an initial series of investigations, detailed ethograms were compiled to describe the animals' repertoire of activities and interactions. Lying and straw manipulation were found to be the predominant behaviours and attacks directed towards the head were the most commonly performed type o

Abstract:

There is evidence from a number of species that body condition or fatness plays a role in the regulation of energy balance, through a direct effect on voluntary food intake (VFI). However, since differences in body condition are frequently confounded with differences in previous nutrition, this study investigated the role of both factors in the control of VFI in sheep. In ewes grazing autumn pastures, there was a negative effect of body condition on VFI, but no independent effect of the previous level of nutrition. However, there was an interaction between the effects of body condition and her

Abstract:

While commonly thought of as a waste product, food scraps and residuals represent an important opportunity for energy and nutrient recapture within the food system. As demands on production continue to increase, conservation of these valuable resources has become a priority area. In the wake of new legislation in Vermont, Act 148, the Universal Recycling Law, the fate of microbial species in food waste, scraps and residuals is increasingly important. The presence of antimicrobial resistance genes in all types of foods calls for an increased need to estimate risk of antibiotic resistance transf

Abstract:

Swine production represents approximately 40% of the world's meat production, and its wastes contain high concentrations of organic carbon, nitrogen (N), and phosphorus (P). Anaerobic digestion is an increasingly popular technology for treating animal wastes while simultaneously generating energy. Its propagation and ability to solubilize organic N and P make adding a struvite recovery process attractive. Recovering struvite (MgNH4PO4) from anaerobically digested swine waste can address global P shortages, meet P discharge guidelines, and produce slow-release fertilizer, which can be sold fo

Growth in the absence of hydrogen in a modular atmosphere controlled system (MACS) was characterised by an intiallag that could be overcome by adding an antioxidant reag

Within the livestock sector, farmers and veterinarians are two groups of people who play a pivotal role in maintaining the health and welfare of animals. How the different welfare needs of farm animals are perceived and prioritised by these two caretaker groups will have direct implications for the animals in their care. People’s perceptions and attitudes directly influence their behaviour, and research has demonstrated that positive attitudes towards animals are paramount to ensuring good animal welfare. The prevention and mitigation of pain is an important component to ensuring good animal w

The purpose of this thesis is to implement Bayesian methods to solve theoretical and practical statistical problems in the selection of animals for breeding. The thesis is therefore mainly on the calculation of posterior distributions of variance components and functions of them, and the construction of optimum Bayesian selection methods for a single quantitative trait and multiple traits. Half-sib family structures are considered throughout, although the theory considered is more general in its application. Conventional and Bayesian methods for variance components estimation are reviewed from

Automatic tracking and video of surveillance on a farm could help to support farm management. In this project, an automated detection system is used to detect sows in surveillance videos. This system is based upon deep learning and computer vision methods. In order to minimize disk storage and to meet the network requirements necessary to achieve the real-performance, tracking in compressed video streams is essential. The proposed system uses a Discriminative Correlation Filter (DCF) as a classifier to detect targets. The tracking model is updated by training the classifier with online learnin

Abstract:

Play is a self-motivated seemingly non-functional behavior mainly observed in young animals. Moreover, play behaviors can be divided into three categories; social play, object play and locomotor play. The type of activity the category contains varies, as play behaviors vary between species. Play behavior is seen as an indicator of positive emotions in animals, therefore play could be an indicator of welfare. However, the relationship between play and welfare requires further studies. In this study, information was compiled from various articles about play and its relation to welfare. Above all

The aggregation of elk during peak transmission allows brucellosis to persist in the feedground populations.
