Hästar som utför vävning
The horse is an animal that often becomes humanized. Despite domestication, the horse still has a need to interact with other horses, be able to move for the most of the day, and being able to graze. If these needs cannot be fulfilled, the horse can be negatively affected and develop abnormal Behaviours. An example of abnormal Behaviours is weaving; the horse performs a swinging motion in the front area of the body during a long time. This literature review aims to investigate how different stabling forms (box/stall) affect the incidence of weaving, and also how this behaviour can be prevented or limited.
Från vilda till domesticerade djur - kan man gå ett steg längre?
Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural Behaviours have been made. These have shown that natural Behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal Behaviours.
Social behaviour and time budget of breeding bulls
The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.
Krubbitning hos häst : implikationer på djurvälfärd och argument för en nollvision om förekomst av beteendet
Most descriptions of stereotypic Behaviours have in common that these repetitive Behaviours only has been observed in captive animals and therefore it has been proposed that stereotypies exist because we house animals in environments that are sub-optimal to them. Some scientists claim that performance of stereotypies in itself decreases the animal's welfare due to costs in time, energy and health and a poorer quality of life. Other scientists assert that individuals performing stereotypies may have a better welfare compared to the rest of the animals in the same environment, since these individuals have developed strategies to cope with stress. Studies have estimated the prevalence of abnormal Behaviours in horses to 18-30 % of the population. Several studies on cribbing have revealed a prevalence of 4-5 %, although some results indicate that more than 10 % of the horse population performs this stereotypy.
Mating behaviour and hierarchy among male warthogs (Phacochoerus africanus) in Kenya
Warthogs live under natural conditions in matriarchal groups, bachelor groups and yearling groups. Just like all pig species do warthogs have a complex behaviour repertoire. The semi-wild warthog population at Kichwa Tembo Lodge, outside Masai Mara National Reserve, lives in a fenced area with access to food all over the year and is protected from predators. The aim of this study was to observe the male warthogs? mating behaviour and their hierarchy during the mating season.
Skiljer sig hundvalpars lekbeteende åt mellan raser och kön? :
There are many theories why animals play but none have jet been proven. During observation on Canids, play seems to be important when they learn to control the intensity of the bite and to facilitate the social structure within a group. When dogs play they perform Behaviours that otherwise are used during hunting, reproduction and aggression that in another context would be for example hostile. The dog is one of the species that we humans have domesticated and they have been exposed to an intense and concentrated breeding so they can function in different areas, for example herding and hunting. This breeding has resulted in that the pure bred dogs can be very different between the breeds.
Användning av smärtskala på marsvin ? experimentell studie i klinikmiljö
Assessing and measuring post-operative pain in all animals is a challenge, but doing it in small mammals, for example guinea pigs, presents an even larger difficulty. Validated pain scales developed for use in dogs in clinical practice are currently available, but no such scale has been widely accepted for use in guinea pigs in the veterinary setting. In this experimental study, six guinea pigs that had undergone surgery and anaesthesia were observed for behavioural changes that could be associated with pain. The six guinea pigs were also given pain scores with the use of Colorado State University Feline Acute Pain Scale (CSU-APSF), a scale which uses both behaviour when not handled, body tension and response to palpation to evaluate pain intensity. The six guinea pigs showed a number of different Behaviours, for example rigid posture, fixed stare and ?wet dog response? (the body is vigourosly shaken), that could be associated with pain.
A comparison of group housing and individual housing for dairy bulls kept for breeding
This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.
Från Monopol Till Konkurrens : Telias hantering av den ökande konkurrensen genom förändrade marknadsföringsstrategier
The Swedish telecommunication market was prior to the official deregulation 1975 characterized by Telia?s former monopoly position. This thesis studies how the deregulation of the market, and the thereby increasing competition, has affected Telia and how it has influenced Telia?s marketing strategies.The theoretical framework, from which the conclusions will be made, is a combination of the theory about strategic learning Behaviours by Slater et al, and Grönroos? theory about a marketing continuum. The empirical work material is the result from two interviews with former key figures at Telia, and a briefing of Telia?s annual report between the years 1993 and 2006.Research findings indicate that Telia has gone from being product oriented with a strong technical focus, to becoming gradually more market oriented with competition orientation but foremost customer orientation as their most distinguished learning Behaviours.
Investigating the bond between research dogs and a familiar person and validation of the Ainsworth's Strange Situation Procedure (ASSP)
In the dog-human relationship humans are the ones who provide the dog with safety and comfort. Ainsworth's Strange Situation Procedure (ASSP), which was originally developed in humans to study the relationship between mothers and infants, has been modified to investigate the emotional bond research dogs have to a familiar person. Twelve research dogs were tested to investigate whether the dogs performed any Behaviours indicating a secure-base effect, such as more exploration and play in the presence of a familiar person and proximity-seeking Behaviours when this person is or has been absent. In the ASSP the dog enters a room with a familiar person, is introduced to a stranger, is left alone for a short period of time and experiences moments of separation and reunion. A second variation of the ASSP was added where the familiar person was replaced by another, to the dog, unfamiliar person.

Minkvalpars beteende i större berikade burar vid olika gruppstorlek :
Farmed mink often perform stereotypic Behaviours which is considered to be a sign of reduced welfare. Previous studies have shown that enriched cages can reduce the frequency of performed stereotypies. Most studies on mink in Sweden have been done on adults. The aim of this study was to investigate if larger enriched cages with two or four mink kits reduce stereotypies in mink kits during their growth period in comparison to traditional cages.
In the present study the Behaviours of mink kits that were kept in four different treatments at a private mink farm were recorded. Traditional cages with two mink kits were used as a reference and the other treatments consisted of larger cages with shelves with two kits, larger cages with shelves and a plastic cylinder with two kits, and larger cages with shelves with four kits.
Hur påverkas dvärghamstrar av att vistas i hamsterbollar?
Lately the popularity to keep different species of dwarf hamsters has increased in Sweden.
The requirements of the Swedish legislation to keep hamsters as pets are low which could be a reason for the increasing popularity. Hamsters are in nature generally nocturnal and can travel far distances to find food sources during their active part of the day. Their eyesight is poor, but is compensated by their well-developed hearing and olfaction. ?Run about balls? are made of plastic and the hamster is placed inside it where after the ball is placed on the floor and the hamster can then run protected outside the cage.
Nytt ljus över dagbesvär vid insomni: spelar psykologiska processer en underskattad roll?
This study examined the psychological processes of autonomic arousal and distress, erroneous beliefs about sleep, worry about sleep, selective attention and monitoring and safety Behaviours related to sleep, on the subject of daytime impairments associated with insomnia. The psychological processes were evaluated against as follows: sleep measures, anxiety, depression, medical disease and the use of medications. The measure daytime impairments complied with the established research diagnostic criteria. A correlation analysis indicated that psychological process, anxiety, depression and one of the sleep measures are associated with daytime impairments. The results of a multiple regression analysis proved that only erroneous beliefs about sleep, worry about sleep and safety Behaviours related to sleep are linked to daytime impairments associated with insomnia.
The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation
The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging Behaviours.
In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in Behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.
