<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>
