Är korta spenar ett problem i samband med mjölkning? :

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

Vi vill inte skriva om böcker. Vi vill prata. : En studie i boksamtalens betydelse för yrkeselevers litteraturläsning.

This qualitative study was conducted to investigate how subordination and superiority emerges in the interaction between heterosexual couples between 20 to 30 years old, without children. Eight semi-structured interviews with four couples have been conducted to provide insight into how subordination and superiority is made in the interaction between the cohabiting couples. All interviews were transcribed and then manually categorized along specific main themes and sub themes. The empirical data were then assayed by a hermeneutic interpretation.   Three previous studies have formed the basis for this study, Det kallas kärlek by Carin Holmberg, the anthology, Jämställdhetens pris and Familjer i tiden by Christine Roman and Helen Peterson. The theoretical framework consists symbolic interactionism, and especially the concept of asymmetrical role-taking and also doing gender.

Effekten av kvävegödsling på gasproduktionen vintertid i boreala sjöar

To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.

Hållning av kastrerade och icke kastrerade försöksmöss i par som en lösning på aggressivt beteende

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Blir ko och kalv mindre stressade vid ko-kalvseparation med nos- och slickkontakt än när de bara kan höra varandra?

The aim for this study was to investigate if it is less stressful for cow and calves in loose housing systems when separation is made so they can see and touch each other (Physical Contact-PC) instead of just hearing each other (Hearing Contact-HC). The behavior of eight cow- calf pairs (n=4 pairs per treatment) on an ecological dairy farm with cubicle housing were studied for four hours directly after separation and four hours the day after separation. The first four cows that gave birth were used for treatment PC, and the following four cows that gave birth were used for treatment HC. The only selection criteria used was that both cow and calf were healthy. Separation took place 3-4 days after birth and the calves were put separately in two different pens while the mothers were let loose into the cubicle system.

Beteenderesponser hos farmuppfödda minkar (Mustela vison) hållna i stora och berikade burar :

The standard housing of farmed mink provides little opportunities for them to behave naturally and abnormal behaviours such as stereotypic behaviour and tail biting may occur. To prevent abnormal behaviours animals in captivity are often provided with different kinds of enrichments. The aim of this study was to investigate what kind of enrichment farmed mink use when they have several kinds to choose from and to observe if abnormal behaviours can be decreased with a larger cage and a more multifaceted environment. Totally 20 silver blue, 10 months old female mink were kept in traditional cages (80x30x40 cm) for 7 days and in larger cages (195x80x40 cm) with several types of enrichments for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding during 7 days per treatment in April 2004.

Prosodisk förmåga hos svenska grundskolebarn med cochleaimplantat

Prosody can be characterized as the rhythm and the melody of speech. Prosodic features convey emotions, thoughts and geographic origins of each individual. Spoken language without prosody would be monotonous, without variations in loudness and rate. Children with cochlear implants perceive speech in a different way than children with normal hearing. Consequently the speech produced by a child with cochlear implants may sound different.The purpose of this study was to examine prosodic skills in Swedish children with cochlear implants and to compare them with the prosodic skills in Swedish children with normal hearing.

How to build a rein tension meter

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.

Kan man genom kartstudier förutse häckningsframgång för ängshök (Circus pygargus) i Uppland? :

Montagu´s harrier (Circus pygargus) is a diurnal, Eurasian raptor, which migrates from its northern breeding grounds to winter in sub-Saharan Africa. In Sweden, its core breeding area is centred on the island of Öland, with a stable breeding population of approximately 40 pairs. The province of Uppland is on the northern end the distribution range, where 4-8 pairs have regularly bred since the 1980s. In Sweden, the Montagu?s harrier is classified as an endangered (EN) species. This classification is partly due to a lack of preferred nesting habitat, such as shrub-lands or dense wetlands with Claudium spp.

The results showed that the congruence of the managers' strengths was 74% whereas that of their weaknesses was 59%..

Färgval hos blomkrabbspindeln (Misumena vatia) med och utan konkurrens

The colour choice of spiders and the effects of competition on this phenomenon were examined in the laboratory using the sit-and-wait predator goldenrod crab spider (Misumena vatia, (Thomisidae)). This species can  be both white and yellow (could also change colour)  and it was here examined whether individuals preferred to sit on flowers which has the same colouration as their bodies. I found that M.vatia showed preference for flowers that matched their own body colour, but when competition was introduced this preference disappear. It seems, however, that position is a factor that can influences the substrate decisions of M. vatia, where the edge of the flower is preferred..
