Factors affecting the heifer´s age at pregnancy
Several factors affect the heifer´s growth and development, the newborn calf´s feeding of co-lostrum during its first hours of life is one important factor. The colostrum contains higher amount of immunoglobulins and insulin growth factors compared to matured milk. A high intake of immunoglobulins from colostrum results in a high blood concentration of immuno-globulins until the age of eight months. This leads to a lower incidence of diseases that can affect the growth and development negatively. Diarrhea is the most common disease in calves younger than 30 days.
Utfodring av föl före och efter avvänjning :
Swedish horse breeders have generally very few mares producing a few foals a year and the
breeders have relatively few traditions, little knowledge and experience to breed foals
successfully. It is therefore important to provide adequate information about new findings in horse nutrition. However, there is not much research about feeding the suckling foal to ensure a sound growth. Current feeding recommendations in the literature seems to be different. This gives a confusing message and the information is difficult to apply.
This paper reviews some publications in the area of feeding the suckling and weaning foal.
Most authors stress that it?s important to start feeding the foal early in life.

Leaders have many tools in their toolbox when it comes to managing their firms, assuring that they are moving in the right direction. One of these tools is vision. Vision can be a powerful tool for steering a company. But to be able to use it fully, you must also understand how vision is best conveyed to employees and followers. If you understand the vision as a tool, you can fully utilize it.
Borrelia burgdorferi : metodutveckling och tillämpning avseende odling och resistensstudier mot komplement, särskilt interaktion med faktor H
The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.
Strategiska Allianser: En studie av inledningsprocessen
The purpose of the essay has been to clarify why and how small companies, whose major resource is knowledge, establish strategic alliances and which opportunities it brings. We have increased our understanding for the concept of strategic alliances through empirical search and through well-known scientist work. The method, which has been used in the essay, is principally qualitative interviews and gathering secondary data from articles from well-known authors. Our study has given that we have found that entering strategic alliances can make growth and by that way create competitive advantages for the company in question. We also found that there are risks with strategic alliances and the company can protect themselves by legal actions.

Från passiv till aktiv strategi - Näringspolitisk förändring och handlingskapacitet i industrikommunerna Bromölla och Östra Göinge
Since the 1980's economic policies has become an important issue in municipalities and more resources are put into projects that are intended to have a positive influence on the local economic growth. From a theoretical perspective of regime theory and a model of local political economy, concerning the strategies chosen by the actors involved designed by Jon Pierre, the discussion points to the fact that it is possible to affect the local development. The municipalities discussed and compared in this thesis, Bromölla and Östra Göinge, have similar prerequisite for growth mainly due to their dependence to large industrial companies.In order to fulfill the aim of the thesis and examine the change in economic policies over time and between the two municipalities a comparative method is used. The creation of local governing coalitions is emphasized which makes efforts and intentions of individual actors crucial for the success of the local economic policies. Bromölla started their more active efforts in the area of economic policies earlier than Östra Göinge and has also come a bit further in the process.
Bärarskap av meticillinresistent Staphylococcus pseudintermedius (MRSP) hos svenska hundar :
During the last years, meticillin resistant Staphylococcus pseudintermedius (MRSP) have caused an increasing number of infections in Swedish dogs. MRSP is resistant against a majority of the antimicrobials available for dogs in Sweden, making it difficult to treat the infection. Our knowledge of the bacterium is limited, making it hard to handle infected dogs in a proper way. The aim of this study was to investigate for how long time dogs, who have an infection caused by MRSP, become carriers of the bacterium. Other factors like treatment with antimicrobials, the correlation between clinical symptoms and carriage, common diagnoses and institutionalization where also looked upon.
Goat production in Laos and the potential of using Erythrina variegata as a feedstuff
Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.

Relationship between social behaviour, feeding behaviour and performance of boars using single-space feeders
A study on the behavioural patterns of growing boars is presented. The study was preformed at Quality Genetics? boar testing station Månseryd in Sweden. The boars were purebred Yorkshire, Hampshire or Landrace, born in nine different nucleus farms. The study is based on two batches of boars, with 63 and 69 boars respectively.
Konstruktion av en fotobioreaktor för odling av alger : ett småskaligt försök
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :
The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings.
A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce.
In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils.
The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season.
The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
A retrospective study of bitches with pyometra and mucometra medically treated with aglepristone
Pyometra is a common and life threatening disease of intact bitches. The disease is caused by a hormonal influence on the uterus in combination with a bacterial infection. The most common treatment is ovariohysterectomy, but several medical options are available to maintain fertility or avoid surgery and anaesthesia. Drugs that can be used for medical treatment are for example progesterone-receptor antagonists, prostaglandins and dopamine agonist. The present study focused on treatment with the progesterone-receptor antagonistaglepristone in combination with antimicrobial therapy.
Samband mellan en längre tillväxtsäsong och en ökad smoltstorlek i Vänerområdet
AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.
Behöver tillväxten en stad? Om Dublin som politisk arena, aktör och tillväxtmotor
This thesis intends to examine the role of the city, Dublin, in the Irish economic growth during the 1990s. It is a case study where Dublin is compared with current theories on post modern cities as growth machines and increasingly prominent actors in the global context. The study has an interdisciplinary approach but focuses on political science issues such as power distribution, global-local governance and local political organisation. It is a theory driven study that also intends to add aspects to the understanding of the cities of our time. I argue that Dublin has faced a lot of changes during the last decades in accordance with the post modern city.
