Seventy-two working horses (they had been ridden with bit and Bridle within the last two weeks) were examined in the oral cavity. Findings and status were noted. The horses were randomly chosen among individuals without clinical symptoms from the mouth and gastrointestinal system. The result showed that 93% of the horses had changes in the mucus membranes, 86% in the form of ulcerations. The P2 region was most commonly affected followed by wounds more caudally in the mouth (P3-M3 region).

Swedish Trotting association was formed in 1925. They are the ones who design the regulations concerning what is permissible and not permissible for the horse, driver and trainer, when they have a license at a Swedish racing track. The Veterinary department of Swedish Trotting association decides in consultation with representatives from veterinaries around the country what is allowed and not allowed, based proven experience, combined with the availability of scientific data and Veterinary Department's own assessment. After stricter regulations for good animal welfare from the Swedish government, Swedish Trotting association is going to work out a workable model for how new equipment can be tested in the future to see how the equipment affects the horse. In the future, all equipment will be objectively tested before approved. The purpose of this work was to develop a well-functioning model for this. The research-question for this work is: Is this study design a well-functioning model of how the equipment should be tested in the future? The equipment used for designing this model was bitless Bridle with a bit.

The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.

The horse was domesticated about 6000 years ago. Since then humans have used the horse for different purposes, such as work force and in sports. Horses are social, group living animals that spend around 16-17 hours a day on grazing. Horses are often kept stabled in single boxes with a limited feeding time. The forage usually contains grain-based concentrates and roughage.

In 1886 Hans Hildebrand received a Bronze Age hoard found in a field that belonged to Eskelhem´s rectory. A record was made where Hildebrand presented and documented the artifacts. The following year Oscar Montelius reviewed the artifacts, which he described as horse gears. He compared the horse gears with similar artifacts found in Europe that roughly had the same dating in order to trace the origin of the hoard.  Montelius conclusion was that the hoard was created on Gotland around 500 BC.
