<p>This thesis is conducted together with the environmental- and health department in Halmstad</p><p>community. The thesis is about allowance of bedding and water supply for pig farms in</p><p>Halmstad community. These farms are chosen randomly from all of the pig farms in</p><p>Halmstad community. It includes inspection of 27 pig farms and writing of a report. During</p><p>the inspections I study the amount of bedding, what kind of bedding, water supply and</p><p>injuries like lameness, shoulder-bone sore, ear-, flank- and pig tail biting. Also the amounts of</p><p>dirty boxes were documented. The reason for this thesis depends on the new regulation about</p><p>bedding that came out the first of October 2007. The regulation about free access of water is</p><p>not new but the community wanted a mapping of these are followed. These inspections show</p><p>that some of the farmers do not follow the regulation about free access of water to the pigs.</p><p>According to the amount of observed shoulder-bone sore and pigtail biting the regulation is</p><p>not followed. According to my investigation there are tendencies of growing amounts of</p><p>shoulder-bone sore when there is too little straw. Sows that get 0-300 grams of straw per box</p><p>per day have a share of 5 % shoulder-bone sore, if the amount of straw increases to 300-600</p><p>grams straw per day the amount of shoulder-bone sore halves. If the amount of straw</p><p>increases to more than 600 grams per day the amount of shoulder-bone sore halves according</p><p>to the sows that get 300-600 grams straw per day. My studies in this subject have shown that</p><p>pig tail biting only existed when the water flow were 3,3 litres per minute or lower. The low</p><p>water flow together with little straw increases the pig tail biting. In the boxes with only 0-300</p><p>gram straw per day the amount of pigtail biting was 4,5 %. If the amount of straw increased to</p><p>more than 300 gram per box a day the amount of pigtail biting was decreased by 50 %.</p><p>Lameness mostly exists on those pigs that get 0-300 grams of straw.</p>

MRSA is a bacteria that is known to cause a wide range of different infections in humans, some more severe than others. In recent years different strains of the bacteria, mainly the MRSA CC398, has been found in many pig farming operations across Europe. Most of Sweden’s pork imports come from Denmark and Germany and the estimation of the prevalence of MRSA in pig farms throughout both countries are more than 50 percent. For this study Sweden were chosen due to the fact that no pigs have been found to carry the infection in this country. The purpose of this study was to find out if legislation and use of antibiotics in each of the countries somehow influence the spreading of the infection, but also to investigate how MRSA transmits between different individuals. The study is split in two parts, namely a literature review and a small survey that were sent to Swedish pig producers. The survey showed that disease protection is important and that 67 percent of the pig producers that answered are worried that MRSA might come to Sweden. From the comparison of the legislation no real conclusion could be made, but antibiotic group treatments of pigs can be linked to an increased incidence of MRSA in pig farms.
