Jämförelse mellan subjektiv och objektiv bedömning av hälta hos häst på böjt spår.
The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.
Herbs for horses
The aim of this study was to find out how many and which of the herbs used for horses that have been scientifically studied with results to justify the use. In order to find out which herbs that are commonly used by horse-owners a phone interview was performed where six companies selling herbs for horses was contacted and asked to provide information on the most sold herbs for horses in Sweden. Devil's claw (Harpagophytum procumbens), chamomile (Matricaria recutita), dandelion (Taraxacum officinalis), nettle (Urtica dioica) and monk's pepper (Vitex agnus-castus) where the most sold herbs, followed by marshmallow (Althaea officinalis), burdock (Arctium lappa), marigold (Calendula officinalis), purple coneflower (Echinacea angustifolia/purpurea), cleavers (Galium aparine), licorice (Glycyrrhiza glabra), rose hip (Rosa canina), thyme (Thymus vulgaris) and vervain (Verbena officinalis), in no particular order. Of the most used herbs, research with focus on the use for horses was found for purple coneflower, licorice, devil's claw, monk's pepper, rose hip, thyme, and vervain. These studies did not cover the whole range of traditional use for the mentioned herbs, and more studies are needed to be able to claim that these herbs have, or have not, scientific support for use in equine management..
Genernas påverkan på köttkvaliteten
Multiple factors are involved in control of beef sensory quality so great variation can be induced. The perception of meat quality can be affected anywhere in the product chain. Both the environment and the set of genes of the animals have an effect on the final output. A problem facing the beef industry today is the significant variations in meat quality between individual animals, which is reflected in the uneven quality of the meat that reaches the consumer. If the quality of meat in stores varies significantly over time, the consumers? trust may decrease.
Glucose markers in healthy and diabetic bitches in different stages of the oestral cycle
The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase.

Prevalens av Sarcoptes scabiei hos thailändska gatuhundar :
The aim of present study was to evaluate the prevalences of Sarcoptes scabiei in Thai stray dogs. The study was performed in Pattaya, Thailand, and included 62 stray dogs, all cross-breeds. Degree and type of skin lesions, and presence of macroscopic ectoparasites were recorded for each individual. Blood samples were collected to determine the seroprevalences of IgG-antibodies against S. scabiei with ELISA.
Effekt på östralcykeln hos ston tillförda GnRH-analogen deslorelin (Ovuplant) :
This article starts with a review of the literature regarding the normal reproductive physiology of the mare, prolonged luteal phase and medical drugs used within reproduction of the horse, with emphasis on Ovuplant®. The purpose of this article was to measure the progesterone level in blood, of mares implanted with deslorelin acetate (Ovuplant®). The study was performed at the Department of Clinical Sciences, SLU, in Uppsala. There were seven mares included in the study. They were divided into two groups, one experimental group (four mares) and one control group (three mares).
Renal dysplasi hos engelsk cocker spaniel :
Renal dysplasi (RD) is a congenital chronic renal disease affecting young dogs. It is a rather common disease that occurs in a large number of dogs and in some breeds there is a familiar incidence or suspected hereditary background. Both the etiology and pathogenesis are still unknown, but a theory about the cause of RD is that the two components that form the kidney, the uretheric bud and the metanephrogenic blastema, don´t interact normally in the embryo. Kidneys affected by RD contain fetal (immature) structures that are inappropriate for the state of development/age of the dog and abnormal structures caused by an abnormal differentiation. Affected dogs usually are under .
Aortainsufficiens hos häst : patofysiologi och behandling
Aortic insufficiency is a very common valve problem in horses and most often affects older individuals, but nevertheless existent within younger ones. The root cause for aortic insufficiency can be varied, for example; endocarditis, ventricular septum defect or congenital valve disease but the most common are progressive valve degeneration or elite competition. Depending on the root cause, different changes can be observed on the aorta valves, but they do all have the same effect, the valves do not seal properly and blood leaks backwards.
Many horses can, even with this deficiency, perform highly without any visible impacts and there is therefore no need to treat those subjects. Most often the symptoms arise at a later stage in life and they are, more often than none, put down for other reasons. In the occurrence of the clinical symptoms showing, treatment guideline is to inhibit these symptoms since the valve degeneration is presently irreversible.
Beteendeproblem hos hund som kan leda till avlivning
Too many dogs are euthanized because of different kind of behaviour problems today. Is it really necessary? Who has the main responsibility for this action? Do breed differences matter when it comes to increased risk of euthanasia of the dog? The purpose of this piece of work is to find the answers to these questions and also to find out what kind of behaviour problems that can lead to euthanasia of dogs in general.
The most common reason for dogs being euthanized is aggression. The aggression can be directed toward humans or other animals, mostly other dogs. There are some important factors of the dog that increases the risk of being euthanized, and these are the breed, the gender and sexual status and also the size of the dog.

Variation in fattening pig exterior, gait and weight gain in commercial organic herds
Pigs in Swedish organic production systems have been shown to have more findings of arthritis at slaughter, compared to pigs in conventional pig production. With this in mind a study was performed, to primary, investigate variation in exterior, gait and weight gain between sire breeds and, secondly, to investigate variation between herds, season, gender, age and assessment occasion on these recordings. Swedish commercial hybrids, crosses between Norwegian Landrace and Swedish Yorkshire were inseminated with either Hampshire or Duroc as terminal sire. All the pigs had known pedigree as each semen dose contained sperms from one individual boar. All piglets were individually tagged closely after birth, and exterior and gait assessment were performed at two separate occasions, early and late during the fattening period.
Jämförelse mellan två olika plastningsprinciper, Cross Pac kontra konventionell plastning :
Baled silage has become one of the most important conservation methods in Sweden. Because
we take our grass as silage we get the quality and the good hygenic that we would like to
have. Silage has become a big buisiness also in the horse feeding where many of the breeders
have changed from the hay to the hay-silage. The difference between regular silage and haysilage
is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands
on machinery and wrapping material since the grass gets sharper and harder to press together
real hard.
The main reason for the test was to compare two different systems for wrapping, the new
Cross Pac and conventional.
Fördelning av frambensskador på ytliga böjsenan hos galopphästar :
Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein.
It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact.
The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries.
The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..
Genetisk variation i brunststyrka hos svenska mjölkkor :
When cows in Sweden are inseminated the heat strength is reported to the Swedish milk-recording scheme and AI scheme. Cows that show strong signs of estrus are desirable and the trait is included in the Swedish breeding goal. A strong heat makes it easier to inseminate at the right time and to avoid long and expensive days open. Since ten years the heat strength is scored from one to five by the farmer and reported to the milk-recording scheme and AI scheme. Earlier the score was from one to three and the decision was made by the AI technician.
Utveckling av metod för utvärdering av synnervens funktion hos häst :
VEP, visual evoked potential is an electrophysiologic test that can be used for evaluating the higher visual pathways. The aim of this study was to investigate if it is possible to adapt this method to horses. This method could have a clinical use in addition to the existing diagnostic methods that are available to evaluate vision in horses.
Firstly, this study contains a summary of relevant studies done on animals and, secondly, an experimental part where the possibility of recording VEP in nonsedated and sedated horses is investigated and where to position the recording electrode to obtain the best results.
Our results show that it is possible to record VEP in horses in a clinical setting. VEP was best recorded in the sedated horse to avoid movement artifacts and other disturbances.
