Bakterietillväxt i strömedel till mjölkkor
The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores.
In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied.
Most bacteria need humidity and prefer a quite high water activity to be able to grow.
En jämförande studie av kalvuppfödningen på KRAV-anslutna och konventionella mjölkgårdar :
In order to investigate if the KRAV-regulations have any effects on the health and welfare of calves, KRAV-affiliated farms were compared to conventional farms with respect to calf management and outcome. The dairy calf has had a low economical impact during history. Even today the value of the calf is low and a lot of calves have a poor health status. The calf breeding is built on tradition and on the fact, that cheap antibiotics have made it possible to ignore, the recommendations about good hygiene in the calf?s environment.
?Man får inte vatten i stövlarna på en gång? : En undersökning om miljöbevakningen i Rapport och Dagens Nyheter i samband med IPCC:s klimatrapporter
The purpose of the study was to find out whether the interaction between mentally disabled individuals and pet positively affects the individual and gives a feeling of well-being to the extent that this might be implicated in the psychologically disabled people?s everyday life in some form of rehabilitation measure. The study is qualitative and builds on an ethnographic design. Data collection was performed through six observations, six interviews and reflections. Interviews were also conducted with relatives and assistants for greater opportunity for follow-up questions, and descriptions of the situation.
Under Terra Novas Stenar : en osteologisk- & arkeologisk analys av ett bronsåldersröse på Gotland
This paper discusses an osteological- and archeological analysis of a cairn from the Bronze Age on Gotland. The osteological material consists of both burnt and and unburnt bones from both human and animal. The objective of this paper is to shed light on the individuals who were buried in the cairn. It is also to generate information about continuity in its use and patterns of distribution of the bones and grave-goods in the cairn. The osteological analysis show that a minimum of five human individuals is present in the osteological material.
Dendroklimatologisk analys av lokalklimat vid Grövelsjön i Dalafjällen
Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation. In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.
Träning av motorisk/postural kontroll
Humans and dogs are both mammals. One of the differences between the two species is that man walk on two legs and dogs on four legs. There are also differences in the nerve system between the two species. The human nerve system is supposed to provide opportunity for fine motor tasks- while the nerve system of the dog is more focused on the ability to perform locomotor tasks. Humans need to increase their motor control and postural control when affected by various conditions and diseases.
Genomisk selektion och uppbyggnaden av avelsprogram hos mjölkkor
During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.
Skador på ytliga böjsenan hos ridhästar - en retrospektiv fallstudie över konservativ behandling :
Injuries of the superficial digital flexor tendon are common in racehorses with many reports on different treatment regimes. However there are few studies in riding horses. The purpose of this study was to document the result of conservative treatment of injuries on the superficial digital flexor tendon in riding horses and to find factors that may be important to the outcome.
Hospital records from 1999 to 2003 of 17 non-racehorses at ATGs Animal Hospital in Skara with the diagnosis tendonitis of the superficial digital flexor tendon were reviewed. Follow-up information on treatment, convalescence and final outcome was collected.
Deltidsbete : effekt på mjölkkornas foderintag och avkastning
Detta arbete är en litteraturstudie som handlar om hur deltidsbete påverkar mjölkkors avkastning, foderintag och välfärd. I Sverige har vi beteskrav till skillnad från många andra länder i världen. Detta skapar problem då besättningstorlekarna ökar och det blir svårare att få marker i närheten av gården att räcka till alla kor. Det största problemet med mjölkkor på bete är dock att högavkastande kor inte producerar lika mycket på bete som inne på stall. Det är därför viktigt att finna ett sätt att lösa problemen som både gynnar kon och bonden.
DJUR : Djurkroppar som material i konst, hantverk och design
Detta examensarbete behandlar fenomenet att använda djurkroppar som material. Studiens syfte är att undersöka fenomenet döda djur och djurkroppar i konst, hantverk och design, och lyfta fram på vilket sätt döda djur används och hur användandet kan tolkas och förstås. Teorin belyser relationen djur och människa ur historiskt perspektiv, hur djur framställts inom konsten, samt den etiska aspekten. Metod och material består i en analys utifrån texter och medier, och en kvalitativ intervju med Märta Mattsson, som skapar smycken av främst insekter. Studien visar på att djur har varit symbol för många olika saker som mod, tapperhet, häxkonst och erotik.
Interaktionskvalitet - hur mäts det?
Den tekniska utvecklingen har lett till att massiva mängder av information sänds, i höga
hastigheter. Detta flöde måste vi lära oss att hantera. För att maximera nyttan av de nya
teknikerna och undkomma de problem som detta enorma informationsflöde bär med sig, bör
interaktionskvalitet studeras. Vi måste anpassa gränssnitt efter användaren eftersom denne
inte har möjlighet att anpassa sig till, och sortera i för stora informationsmängder. Vi måste
utveckla system som gör människan mer effektiv vid användande av gränssnitt.
För att anpassa gränssnitten efter användarens behov och begränsningar krävs kunskaper
om den mänskliga kognitionen.
Granföryngring på tallmark, hur ofta förekommer det? :
This survey was made during the summer of 2004 and the spring of 2005, on commission
from the National Board of Forestry.
The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.
Population and management models for the Swedish wild boar (Sus scrofa)
The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.
Laktatnivån i blodet : en prognostisk markör för tikar med pyometra?
The purpose of the present study was to explore if blood lactate levels are increased in bitches with pyometra, and if the lactate measurement could be used as a prognostic indicator and to determine outcome. The present study
included 16 bitches with pyometra that were admitted to the University Animal Hospital, Swedish University of Agricultural Sciences, Uppsala, Sweden. For comparison, a control group consisting of 14 healthy staffowned
bitches was also evaluated. In all bitches, a physical examination was performed and blood samples for analysis of haematological and biochemical parameters were obtained. In all bitches with pyometra, surgical ovariohysterectomy was performed and a uterine sample for bacteriological culture and identification was collected.
Avelsarbete med mjölkproducerande getter ? fokus på Norge och Frankrike
The main part of the goats in the world is located in developing countries, whereas active breeding programs are mainly restricted to Northern America and Europe. Goat milk can be processed to several products and goat cheese is the main product. An organized breeding program is carried out in France and Norway but is not present in Sweden. Important selection traits for milk producing goats include milk, protein and fat yield along with protein and fat content. Functional traits have been more important the past years and they have large economic importance for the farmers.
