The aim of this study is to with the help of my data, conduct statistic analyses about animal welfare mistakes and scarities, as a preventive measure for the public sector point of view and how farmers handle their animals in these cases, when and how these mistakes and scarities are likely to appear and in this way perhaps manage the existing problems. The aim of using judicial decisions of banning ownership and caretaking of animals according to the 29 § is that this judicial decision is the outermost fortification of animal welfare. In November 1938 the pro tempore investigator handed over a report with a proposition according the animal welfare legislation. Pro tempore proposed that the court should in some cases, be able to order a person guilty of cruelty against animals to a ban of owning or taking care of animals. This proposal unfortunately was turned down. The question about introduce a ban against owning or taking care of animals into the Swedish animal welfare legislation was again discussed in April 1967 at an interpellation debate in the parliaments second chamber.

Japanese encephalitis virus (JEV) is one of the leading causes of acute encephalitis in humans. The virus is spread by mosquitoes, mainly belonging to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept in households owning 10 pigs or less, pigs are widely spread across most parts of the country.

In 1936 a governmental breeding project was started with aim on military use. The police later came to use dogs from this project as well. In order to utilize dogs that could fit for other purposes training and education of dogs for search of different substances and of guide dogs for blind persons was performed. A political decision to privatize the whole dog programme was taken in 1992. During most part of the time one had serious economical issues since too few of the dogs that were bred could be considered to fulfil the basic demands for service. To satisfy the need of service dogs private bred dogs were bought as well.

Veterinärer måste navigera mellan många olika intressen och faktorer i sin yrkesutövning: djuret, dess djurägare, samhällets förväntningar, kollegial lojalitet och ekonomiska överväganden. Det är inte alltid självklart vilka intressen som ska väga tyngst; speciellt inte då synen på djurs moraliska status och (egen)värde varierar, både inom yrkeskåren, befolkningen i stort och inom moralfilosofin. Synen på djur har under stor del av historien dominerats av ett antropocentriskt förhållningssätt, i extrema fall har djur setts som maskiner. Idag finns en mångfald av djuretiska teorier och en global rörelse som ifrågasätter människans behandling av djur. Utilitarism och rättighetsetik är exempel på två filosofier som explicit utmanar dagens djurhållning, den senare också det faktum att djur dödas för människans skull.
