Fullfoder till mjölkkor i Sverige

Syftet med litteraturstudien var att sammanfatta den forskning och litteratur som finns om fullfoder i Sverige. Hur utformas ett bra fullfodersystem med hänsyn till näringsinnehåll, fodrets struktur och fiberinnehåll samt praktik i Sverige? I vilka besättningar lämpar sig ett fullfodersystem bäst? Definitionen på fullfoder är att alla fodermedel förutom vatten blandas samman innan utfodring. Det medför ett jämt flöde av fodermedlen till våmmen vilket stabiliserar dess miljö. Användningen av fullfoder blir allt vanligare i Sverige, framförallt eftersom systemet är enkelt att expandera och besättningsstorleken ökar.

Identifiering av lakbara potentiellt farliga ämnen i gummiasfalt

The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.

Vibrationsdämpning av värmepump

Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

Early immune responses to an adjuvant (AbISCO-100) tested in porcine peripheral blood mononuclear cell

Immune stimulating complex (iscom) matrix is a formulation that is used as anadjuvant within research. The capability of the iscom matrix to elicit an immuneresponse when not present together with an antigen has not been extensivelyinvestigated. One way to evaluate the status of the immune system is to measure theamount of cytokines that usually are produced by various cell types during an immuneresponse. The aim of the present study was to evaluate the early immune responses inporcine peripheral blood mononuclear cells (PBMC) after stimulation in vitro with theiscom matrix, AbISCO®-100. The immune response was evaluated by measuring themRNA expression for various cytokines, a chemokine receptor (CXCR4) andregulator of G-protein signaling (RGS16) in porcine PBMC after stimulation withAbISCO®-100 or other inducers like a lipopolysaccharide (LPS) and a CpGoligodeoxynucleotide (ODN 2216) used as controls.

Pedagogisk måltid i förskolan : Förskolepedagogers attityder och ätande

Syftet med denna studie var att undersöka huruvida det finns skillnader i förskolepersonalens lunchmåltid beroende på om de äter pedagogisk lunch, det vill säga samma mat som barnen, eller medhavd matlåda. Studiedesignen är av beskrivande och jämförande karaktär, och undersökningen skedde i en medelstor svensk stad där tre förskolors kvinnliga personal deltog. Tolv individuella halvstrukturerade telefonintervjuer genomfördes. Sex pedagoger åt samma mat som barnen och övriga medförd matlåda. Resultatet visade att respondenterna som åt medhavd matlåda hade ett högre totalt energiintag i form av protein, fett, men även en högre konsumtion av c-vitamin och järn.

Betesdrift för mjölkkor :

The Swedish Animal Welfare Act say that all milking cows must have access to pasture in summer time. That was a gift to Astrid Lindgren o her 80th birthday from the Swedish Government. Sweden is a predecessor in animal welfare, but how well do we live up to these big expectations? In this thesis I will examine how well the pasture for milking cows works. I have been interviewing farmers with milking cows and people in the business. I have also been searching information on Internet, and using the library of Alnarp. Cows that are kept on pasture are exposed to different kind of parasites, but on the other hand they run a smaller risk to getting acetonemi, pareses and udder infection. Veterinary Pierre Nordmark means that cows on pasture are more healthy then cows kept inside all summer.

Butorfanol till get : farmakokinetik efter subkutan injektion

Today there are no analgesic drugs approved to be used in goats. Drugs approved for use in other species are consequently being used without knowing the pharmacokinetics of these drugs in goats. The purpose of this study was to investigate the pharmacokinetics of the opioid butorphanol when given subcutaneously in goats. Subcutaneous administration might extend the half-life compared to intravenous or intramuscular administration. Eight clinically healthy, non-pregnant 6 months old female goats were used.

?Processutveckling av metod f?r tillverkning av en funktionell tibetansk mejeriprodukt?

Probiotics is a special group of health products on the market. The most common type of  these is live cultures of lactic acid fermenting bacteria from raw milk . These include, among others, yogurt and various trademarks such as Hälsofil ®, Acidophilus ®, Dofilus ® and Kefir ®. Such products are often used by patients who are treated with antibiotics to combat the intestinal flora eliminated, thus causing digestive problems. The present work deals with yet another type of health product, viz.

Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Bestämning av utfallet av translokationen t(11;18)(q21;q21) hos patienter med MALT-lymfom genom FISH analys

Lymphoma is a group of malignant tumour diseases developing in the secondary lymphatic system. These diseases can develop in all organs as lymphocytes are ubiquitously in the body. In connection to mucus membranes we find mucosa-associated lymphoid tissue, MALT, in which lymphoma can spontaneously but slowly develop, mostly at chronic inflammation or at autoimmune diseases. Today these diseases are incureable with the exception of some cases caused by Helicobacter pylori-infection. Antibiotic treatment of these cases can induce remissions.MALT-lymphomas have characteristic histological and molecular properties.

Produktion av single cell protein från restströmmar från 2:a generationens bioetanolproduktion

Rapporten ingår i ett FoU- projekt för Högskolan Dalarna, där målet är att ta fram en konstruktion utan ångspärr som ska klara dagens mått på lufttäthet och fuktkrav.Syftet med denna rapport är att utreda hur fukt påverkar en byggnad medmassivträstomme och olika isoleringsmaterial utan ångspärr. Mineralull och träfiberisolering jämförs mot varandra för att se hur dessa påverkarfuktbelastningen i en väggkonstruktion. Testobjektet är lokaliserat i Dalarna, inget fukttillskott har funnits inomhus i byggnaden.För att genomföra detta arbete har tre stycken olika metoder används. Ensimulering, verkliga uppmätta värden och en provtagning. Fuktsimuleringen genomfördes med hjälp av programmet WUFI, uppmätta värden i form av relativ fuktighet och temperatur har samlats in kontinuerligt under två års tid från väggkonstruktionen via mätsensorer.

Tillväxt i medelstora företag: En problem- och åtgärdsanalys för tillväxt hos Sveriges "bortglömda" företag

Many sources point to the same conclusion; throughout the history the research sphere, mass media, governmental industry policies and public life in common have not paid the same attention to medium-sized companies as to small, new or large companies in Sweden. Yet, there are some researchers claiming the need for the medium-sized companies to grow, becoming tomorrow?s Swedish new large companies. Hence, the need for understanding the specific growth conditions of the medium-sized companies are definitely clear. This study aims firstly to identify whether there are specific requirements and obstacles for growth in connection to being a medium-sized company.

Ombyggnation av ett stall för bundna mjölkkor till boxsystem för rekryteringskvigor

To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..
