Ensiling wet brewer's waste in peri-urban areas of Kampala, Uganda
Ett av de vanligaste fodermedlen hos jordbrukare i Kampala är drav, en biprodukt vid ölframställning. Hög efterfrågan, dyr transport samt dålig lagringskapacitet leder till att tillgången på drav begränsas. Ett sätt att lagra drav och således förbättra tillgängligheten är genom ensilering. Denna studie genomfördes som en Minor Field Study, och var en del i ett projekt mellan SLU och Makerere University, ?feed for livestock in urban/peri-urban areas of Kampala?.
Prevalence of subclinical mastitis in dairy farms in urban and peri-urban areas of Kampala, Uganda
En operation framkallar en icke önskvärd fysiologisk reaktion hos patienten som benämns som kroppens stressvar. Stressvaret innebär att sympatiska nervsystemet aktiveras och att endokrina ändringar erhålls, bland annat minskning i sekretionen av TSH och insulin samt ökning i sekretionen av ACTH, kortisol och ADH.
En viktig uppgift för en veterinär är att välja premedicineringsläkemedel innan en operation. Premedicineringsläkemedel har som främsta uppgifter att motverka det perioperativa stressvaret hos djuret, minska smärta och förstärka anestesimedlens effekt. Syftet med det här arbetet är att beskriva vad som händer i kroppen vid ett perioperativt stressvar och hur svaret kan motverkas med hjälp av premedicineringsläkemedel.
Premedicineringsläkemedel väljs och kombineras från klasserna sedativa, analgetika och antikolinergika. De vanligaste använda sederande läkemedlen på svenska veterinärkliniker är dopaminantagonisten acepromazin och alfa2-agonisten medetomidin.
On the hunt for improvements : possibilities of increasing welfare in captive cheetahs through hunting enrichment
The cheetah (Acinonyx jubatus) is one of the big feline species kept in zoos worldwide. The wild populations are quite small and therefore the captive population make up an important part of the total population of the world. Although life in the wild is not always easy and a captive environment provides shelter and food it does not come without problems. In captivity cheetahs become chronically ill and also develop stereotypic behaviours. Neither of these are problems in wild populations and both can be linked to stress in captivity.
Mykotoxiner i spannmål : hur påverkar dessa mjölkkors hälsa och mjölkens kvalité?
Mykotoxiner är sekundära metaboliter från mögelsvampar som ger toxiska effekter hos djur och människa. Mögelsvampar kan infektera spannmål både på fält och under lagring och kan då producera mykotoxiner vilket innebär att dessa toxiner kan förekomma i fodret till kor. Syftet med den här litteraturstudien är att utreda riskerna med några av de vanligaste mykotoxinerna i spannmål när dessa förekommer i foder till mjölkkor. Fokus har lagts på aflatoxiner, deoxynivalenol (DON) och zearalenon. Litteraturstudien tar upp deras metabolism, hälsopåverkan samt om de förs över i mjölken och även kan utgöra en risk för oss som konsumenter.
Trots att idisslare har högre tolerans mot mykotoxiner än enkelmagade djur så kan även mjölkkors hälsa påverkas.
Evaluation of tools for analysis and quantification of Fusarium mycotoxins
Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.
Outbreaks of African swine fever in domestic pigs in Gulu district, Uganda
The demand for animal products has increased in the last decades, especially for poultry and pork. Pork production has increased drastically globally, and also in Uganda. Thirty-one percent of Uganda´s population lives in poverty. Pig production is believed to play a crucial role in poverty alleviation, because of the ability to convert low quality feed into high quality protein together with high reproductive potential.
African swine fever (ASF) is a lethal disease of domestic pigs often characterized by haemorrhagic fever and with mortality rates up to 100%. The disease is endemic in most sub-Saharan countries and since 2007 in the Russian Federation and Caucasus area.
Påverkas stereotypt vandrande hos amurleopard (Panthera pardus orientalis) vid ökad förutsägbarhet i samband med utfodring?
Stereotypic pacing is frequently observed in captive carnivores, however the underlying causes of this behaviour remain somewhat unclear. One of these possible causes are unpredictable feeding signals, which may give rise to frustration and subsequent pacing. Animal keepers at Nordens Ark had noticed that their Amur leopards had shown stereotypic pacing in connection to the passing of ATVs (All Terrain Vehicles) used by animal keepers primarly when feeding the animals in the park. The aim of this study was to investigate whether the stereotypic pacing of the two Amur leopards at Nordens Ark were affected by the introduction of a signal associated with feeding. The leopards were trained by classical conditioning to associate the sound of a siren with the delivery of food by an animal keeper.
Vitamin A och E i relation till hästutfodring :
The purpose of this study was to examine vitamin A and E in equine nutrition and especially in relation to forages. A literature review was conducted to examine factors that influence the level of vitamins present in forage, the vitamin A and E requirement of horses, and the absorption of vitamin A and E in horses. The influence of DM level on alpha-tocopherol and beta-carotene content in ensiled forage was investigated in a controlled ensiling study using baled silage and haylage. The results from the ensiling study were combined with data of vitamin A and E concentrations collected from literature. Calculations were done to theoretically establish how well the vitamin content in ensiled forage can cover the
maintenance requirements of vitamin A and E in horses.

Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor
In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.
Ekologisk och småskalig uppfödning av slaktkyckling och kalkon i Sverige :
In Sweden in January 2005, there is only one producer of organic broilers and
none of organic turkeys. But there are, on the other hand, a few small-scale
producers whose housing systems to some extent are similar to what is stipulated
in the organic standards. The aims of this work are to investigate what housing
systems are used by the Swedish small-scale producers of broilers and turkeys,
what main challenges they are confronted with and if there is an interest and a
possibility for a change-over to organic production.
For the first part of this work a literature study was performed with the
purpose of detecting the main health problems in conventional as well as smallscale
production. A special focus was on coccidiosis and leg weakness as those
were considered to be of particular importance.
A study was made of Swedish small-scale poultry production units. In two
groups of broilers from the same producer and in three flocks of turkeys the level
of Eimeria oocysts in faeces and litter was investigated.
Policies affecting the competitiveness of dairy production in Sweden, Denmark and Germany
Denmark, Germany and Sweden are along with 24 other countries members of the European Union. Being part of the European Union also means being part of a European market. Within the union barriers for trade has been abolished in order to create more open market. This open market has also contributed towards a more globalized market for dairy products. What used to be a domestic market has become globalised with increasing trade among the members.
JB-TOTALSONDERING : Jämförande sonderingar och utvärdering av egenskaper i isälvsavlagringar kring Igelstaviken
The main purpose of this thesis has been to find a way to evaluate the soil parameters for the Total sounding method (TS), such as the inner friction angles and settlement modules. This study only includes an analysis of soil profiles from the Stockholm region. The chosen location for the study is a proposed residential area east of Igelstaviken in Södertälje. Presently, the subject plot is located in a residential area and is also adjacent to a school area.Total sounding is originally a Norwegian soil testing method. The differences between the sounding methods (weight-, ram-, CPT-sounding) are for instance how the sound is driven into the ground and what kind of parameters that are registered.
Ordning och studiero i klassrumme : En studie om lärares och specialpedagogers uppfattningar om arbetet
Teachers and special education teachers play a vital role in the creation of a study environment that fosters productivity in students. The current study aims to further expand the knowledge regarding teacher?s perception of common work with developing an optimal study environment within the classroom and the educational institution. In order to achieve this, qualitative interviews have been performed and study results analyzed according Nilholm´s model of the three different perspectives on special education: The critical perspective, the compensatory perspective and the dilemma perspective.The study results show that the concept of order and study environment is not clearly defined among the interviewees. However, the concept appears to presuppose the teacher?s responsibility to create the sense of security and effective study environment to those students who express the wish to educate themselves (Children make the things right only if they have been shown the correct way to do it).
Erfarenhetsåterföring i praktiken : En studie vid Jernhusen AB
This examination has been made in cooperation with Jernhusen which is an estate company owned by the government, with estates along the railways in Sweden. This assignment is to help Jernhusens business area Projektfastigheter with their experience feedback, which is to-day almost absent. Business area Projektfastigheter has the task of supporting Jernhusens three other business areas with skills and resources for the estate projects that Jernhusen runs. Jernhusen must become stronger with the collecting of experiences and as a business because of the liberalization of the railways, which leads to a more competitive market. A tool for this is successful experience feedback.The concept of experience feedback is to gain experience across a variety of cases, where individuals and/or groups can chose situations with relevant similarities and differences with current case.
