The purpose of this literature study was to describe the seasonal reproduction in sheep and the presence of genetic variation in fertility traits. Methods to induce oestrus are described and the possibilities to change the reproduction season through breeding are discussed. Sheep have a pronounced seasonality in their reproduction. Mating season starts in the fall and the lambs are born during the spring because this is the most beneficial time. The market request for lamb meat has increased and therefore it is desirable with ewes that could get pregnant all year round.

AbstractThe genetic diversity in cultural plants is considered to be threatened due to global climate change and antropogenic influence. Unknowing of future conditions for cultivation, gene banks all over the world are now trying to build up costly safety nets of species and varieties that may become highly valuable owing to their specific traits and genetic heredity. Hence, in 2002 there was a national inventory, aimed at the Swedish public, asking for seeds believed to be lost. Among the resulting collected seeds were some accessions of garden bean, Phaseolus vulgaris. The objective of this particular study was to assemble a collection of unique varieties and discard possible duplicates.

Ovine black coat colour is determined by the MC1R (Melanocortin 1 receptor) and ASIP (Agouti signalling peptide) genes at the Agouti and Extension loci. The black phenotype is caused by production of eumelanin by melanocytes, whereas yellow-tan or light phenotype is the result of phaeomelanin synthesis. The ovine MC1R gene has two known alleles: the wildtype (E+) and the dominant black (ED) alleles. Two missense mutations (c.218T>A and c.361G>A) constitute ED. The presence of a third allele, the e allele, is proposed and believed to give rise to phaeomelanic phenotype.

The purpose with our essay was to examine which clients/patients get treatment for alcohol problems from either health care units or social service units. We also wanted to find out how staff in these units considers the importance of social background in the assessment of treatment. The questions we have focused are: How do the clients/patients get in contact with the units? How does staff in these units consider the importance of social background in the assessment of treatment? How is the social background like for the present clients/patients? To fulfil the purpose with our investigation and to get answers to our questions, we performed an explorative examination and applied a qualitative method in the form of a semi-structured interview with six persons. The investigation showed that clients/patients get in contact with the units by looking for treatment by themselves or by relatives and other organisations.

In today?s genetic evaluation of Swedish beef cattle, mainly traits that are directly related to productivity are measured. However, other traits, such as temperament and mature cow weight affect the economy of the farmer, as well as the welfare of the animals. This thesis evaluates possible ways of measuring new traits, with focus on temperament and mature weight of suckler cows. The goal is to examine the possible benefits of including these traits in the Swedish breeding scheme.

Dilated cardiomyopathy (DCM) is the second most common heart disease in dogs. Since the disease is seen more frequently in certain breeds, among them Newfoundland dogs, a genetic factor is suspected. This study was partly undertaken to investigate whether there is a significant sex predilection regarding DCM. Moreover, the difference in mean age of death between male dogs and females with DCM was investigated, as well as males and females dying from DCM compared to dying from other reasons (i.e. without DCM).

IT has become more evident in most organisations and has grown to be a part of the infrastructure rather than a tool for competitiveness. Therefore focus should now lie on how IT is adjusted to the business rather than on the usage of IT. To make the best use of IT in the business the CIO needs to start think more business-oriented instead of as before, technology-oriented. To develop the IT-department in that direction the IT-staff need to start cooperate with the business and gain knowledge about stakeholders, markets and the way of working for other staff members in the business.With this as a basis, the purpose of this thesis is to investigate attitudes regarding cooperation between the IT-department and the business and if there is any difference if the CIO has business related background or not.To fulfil the purpose a quantitative investigation with the help of surveys was conducted. The sample consisted of 18 companies with 100-200 employees in the area of Jönköping.

As the quality of internationally competing horses is increasing, a debate concerning the breeding goal of the Swedish Warmblood horse has arisen. Some people claim that the breeding goal should be divided into two separate goals in the future; one for show jumping horses and another one for dressage horses. At the same time others claim that since the largest group of people using the Swedish Warmblood horse today is amateur riders, the needs of these riders should be taken into a larger consideration in the breeding program. The largest emphasis in this matter is on the horses? temperament. The objective of the study was to investigate what the majority of the Swedish horse people think about a variety of questions concerning today?s breeding goal of the Swedish Warmblood horse.

Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.

The main reason for the study was to find out how much naturscience is used in the daily situation in the preschool/school environment with the younger kids. I have studied the teacher`s educations background, if this had any role in the teaching of naturscience. To get my answers I interviewed ten teachers with different teaching background.The result showed that science was present both in the preschool and school for the early years. Everything from teamwork to outdoor play and small experiments. To play out in the woods is most important part teaching in naturscience.My study showed that a teacher`s educations background had no part in the teaching of everyday life in the nature.Keyword: experiment, primary, school, science..

This article presents a retrospective case study combined with a review of the current literature concerning canine gestational diabetes. A total of 14 cases have been collected from six different clinics in Sweden. There are few previously published reports on canine gestational diabetes. Gestational diabetes is a disease that rarely occurs in pregnant bitches. The condition is due to the rise of progesterone that occurs during the estrus cycle.

The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.

This thesis highlights the importance of social relationships for high school adolescents? identity in a multicultural school in Stockholm?s suburb. The second purpose of this thesis is to shed light on, if the school sees the students? cultural background as an asset and how teachers can take advantage and implement it to the way they teach .The theories in the study were developed by Urie Bronnfenbrenner; The ecological theory, Pierre Bourdeau; The three forms of capital and George H. Mead; The significant other, The generalized other and "I" and "Me".
