Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and Breed of the pig.

The German equine housing system, HIT Active Stable?, are adjusted for keeping horses in groups, and are well establishes in Germany. Now the system attracts attention here in Sweden. The purpose of this study was to investigate if the horses have any be-haviours need of free access to roughages like straw or hay, after they have been visit the concentrate feeding station. A study was carried out at family Krohn?s active stables in Bönningstedt, Germany.

The purpose of this Master thesis is to examine and describe dog Breeders? information activities. Questions posed in this study are:? What are the information needs of dog Breeders?? How does the dog Breeder seek and use information?? How can the relationship between serious leisure and information activities be described?The theoretical framework consists of the sociologist Robert A Stebbins? theory about serious leisure. The study is based on a qualitative methodology.

Drinking water from drilled wells has a high content of iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the iron content in water and the health of dairy cows. Initially a literature study was made about iron and it´s function in ruminants.

Ossification of the collateral cartilages of the distal phalanx has been studied primarily in cold blooded horses. The clinical relevance of this condition is unknown. Despite this fact, since 1939, all Swedish Ardenner stallions have had to be classified as being free from this ossification to be approved for Breeding. Initially, palpation was used as a diagnostic method, but since 1982 radiology has been the only method used. The aim of this study was to assess the outcome of 68 years of Breeding program. Dorsopalmar radiographs were taken of the front feet of 58 Ardenners (30 mares, 8 geldings and 20 stallions) and the ossification of the collateral cartilages was evaluated and graded according to three different scales; - Ruohoniemi (grade 0-5), - Swedish University of Agricultural Science (grade 0-3), - and a new scale (grade 0-3), developed for this study.

The purpose of the study was to describe the nurse´s role and experiences aroundpreparation of children in front of peripheral venous catheter (PVC) placement andblood draw. The study used a descriptive design with qualitative approach and wasperformed on a pediatric clinic in Sweden. Semi-structured interviews were performedwith seven nurses of whom the first was a pilot interview, which was included in theresult. The recruitment of nurses was made by a purposeful sampling, maximumvariation sampling, with help of the quality coordinator of the pediatric clinic. Thecollected data was analyzed with the manifest qualitative content method.

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red Breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

Steroid-responsive meningitis-arteritis (SRMA) is a common form of meningitis in dogs. The condition is immunopathological, but the etiology is not yet fully understood. The aim of this study was to compile facts about the disease from records of Swedish dogs. The owners were interviewed by telephone for follow up where it was possible. 15 dogs were included in the study. All of them were neurologically examined in the Small Animal Clinic at the Swedish University of Agricultural Sciences.

Farmers? main reason for crossBreeding dairy cows is that they have seen a decline in functional traits, especially in the Holstein Breed. Throughout crossBreeding, the farmers can combine functional and production traits of different dairy Breeds and utilize the heterosis effects which emerge when two or more Breeds are crossed. Results from different studies with Holstein crossed with Jersey, Brown Swiss, Normande and Scandinavian Red have shown that the crosses had higher fertility, longer productive life, had fewer stillborn calves and had easier calvings than purebred Holstein. The Holstein crosses have shown very good results and sometimes even better than the purebred Holstein for fat production, which gave higher amount of energy corrected milk (ECM) and higher income for the farmers.

The purpose of this literature study was to investigate the possibilities to improve longevity and stayability of beef cattle with Breeding. The Breeding goal for beef Breeds is to produce animals with high capacity for growth and good feed efficiency. Longevity and sustainability are two important features to include in the Breeding goal. If longevity is increased each cow can produce more calves and the number of female calves used for recruitment can be reduced and only the best heifers need to be selected for Breeding. The benefits of longer life is that it lowers the costs of recruitment animals, it increases the number of young animals that become available for slaughter, and it increases the proportion of high producing animals in the herds.

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.
