Diagnosis and molecular epidemiology of bovine rotavirus and coronarvirus in Brazil
Rotavirus and coronavirus are the two most common viral causes of neonatal calf diarrhea and their presence causes a lot of economic damage to the farmers as well as suffering to the animal. By getting better knowledge about the viruses we may help in tracing transmission and in producing new vaccines. This paper served to study the molecular epidemiology of rotavirus and coronavirus in fecal samples collected from two different farms in the state of São Paulo, Brazil. These samples have been studied with focus on the gene VP4, VP7, NSP4 in rotavirus and the gene S1 in coronavirus. From the first farm the screening PCR showed that 12/48 samples were positive for rotavirus and 4/48 positive for coronavirus.
Födosammansättning hos gråsäl (Halichoerus grypus) samt test av flotte för insamling av sälfekalier.
During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.
Tillskottsutfodring av smågrisar under digivningsperioden :
Weaning is one of the most critical events in the piglet production with problems such as growth check and post-weaning diarrhea as a result. The lighter the piglets are when the growth check occurs, the harder they have to get back to normal growth rate. Creep feeding of piglets is used to reduce the problems by increasing the weaning weight and adapting the digestive tract to a starter diet. Hodge (1974) showed that the sow?s milk can not provide enough nutrients for maximal growth rate.
Gårdssmedjor i södra Gästrikland En studie av Hedesunda och Österfärnebo socknar
Poorly maintained forges are a common sight in the province of Gästrikland. Because of their changed appearance, possible move from the origin location and poor items related knowledge they will rarely qualify for the range of funds available through Länsstyrelsen. Therefore this study deals with the problems associated with the forges in southern Gästrikland, i.e. Hedesunda and Österfärnebo parishes.The aim of the study is to increase the items related knowledge of forges and perhaps form the basis for restoration projects in the area. Eleven forges have been examined and the changes they have undergone have been highlighted.A forge was erected on the farm and was used for the households needs such as producing and repairing tools.
Inventering av flodpärlmussla i Fylleån norr om Gyltigesjön
Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.
Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder
This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).
Fullfoder och blandfoder till mjölkkor : vad är viktigt för att lyckas enligt rådgivare och lantbrukare?
Total mixed rations (TMR) and TMR complemented with individual grain feeding to dairy cows are a growing practice in Sweden. This is because the heard sizes of the farms are increasing. Some farmers and farm advisors in Sweden have great knowledge and practical experience of working with TMR. In the same time there are many advisors that do not know how to handle TMR and farms that have a group based feeding of their animals.
In this MSc thesis, the knowledge of farmers that use TMR and advisors with lots of experience of TMR are gathered, with the aim to create a guide book for advisors that are about to start or just have started working with TMR.
Kreditgivning till lantbruksföretag : en jämförelse mellan Sverige och Danmark
In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease.
This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.
Utformning av entréområdet till Maglarps Golf på Lyckebo gård i Skåne : ett designförslag inspirerat av trädgårdshistorien kombinerat med dagens publika krav på en golfanläggning
Lyckebo farm is the original name of the four building big farm, where year 2000, the former farmer established Maglarp/ Lyckebo golfcourse on his land of culture. In 2007, new owners are approaching the Maglarps golfcourse with thoughts of expanding the business. A first step in that direction is to form the area of the entrance, the specific area the visitors are staying at before entering the actual golfcourse to play.
The designproposal is inspired by the peasant garden history of southern Sweden during the nineteenth centuary. It also aims to satisfy the demands of function and usefullness of a golfcourse today.
Information till mjölkföretaget : vilken information behövs och hur bör den utformas när gården ska ta investeringsbeslut?
The fast developments in information and data technology during the recent years have accentuated the need for the business manager to interpret and act on information from the surrounding environment. Today we know little about what information is really used in the unique decision-making. Further, little is known about how information should be designed to fit people with a more intuitive approach to interpreting information. This study is therefore about the difference between peoples approach to interpreting information and how information should be designed to fit those with a more intuitive approach to interpreting information. The application is made to dairy farms in Sweden.
The literature review describes the strategic leadership, the decision-making process and the intuitive and the analytic thinking.
Bristen på arrendemark som hinder för expansion av lantbruksföretag : arrendelagstiftningens och gårdsstödets påverkan på den svenska arrendemarknaden
Improved profitability, a reasonable yearly income or the possibility to have employees are all incentives for expansion. A prerequisite for farm businesses to expand is for land to be made available, either to buy or to rent. In Sweden, 43 % of the total arable land is leasehold land, which implies that a functioning leasehold market is of great importance for the Swedish agriculture. Several factors can affect the supply of leasehold land, for instance the leasehold legislation and the Single Payment Scheme. The fact that the leasehold legislation is compulsory, in protection of the leaseholder, might keep land owners from leasing their land out.
Hållbar och funktionell utemiljö för järnvägsstationer
In a time when milk producing farm businesses face decline in profitability it is of great importance to examine how the situation can be improved. This thesis is a study off efficiency in milk producing farm businesses represented by Swedish, Dutch and German farms. The aim of this study is to investigate whether any differences exist between companies in these countries. Moreover, the study includes a mapping of a number of factors that determine how efficient milk production can be managed. This mapping is based on a literature review on prior efficiency studies followed by qualitative interviews with milk production advisors as well as a questionnaire sent out to dairy farmers in Sweden.
Räfstens vår : Skillnader och likheter i rannsakning och bestraffning ur ett genusperspektiv under ärkebiskop Angermannus visitationsresa våren 1596
The aim of this study was to investigate and analyze similarities and differences in trials and punishment from a gender perspective, during the inquisition in the episcopate of Linköping. A inquisition initiated by duke Karl but performed by archbishop Abraham Angermannus in the year 1596.During the working process a quantitive method was used in the purpose of getting statistic data considering number of men and women that were trialed and punished. A hermeneutic qualitive method was also used in the purpose of closer investigating certain cases that men and women were involved in. The theoretical concepts that have been of importance and used in this study are the individual and the female subject that is based on gender in judicial procedures.The results showed that 49 % of the men were trialed for quarrel. Not as many men were trialed for contempt towards the church and witchery.The most frequently used corporal punishment in this cases were flogging that were executed for totally 38 % of the men.The investigation also proved that men were punished with these forms of corporal punishments for showing their contempt towards the church.
Utvecklingsalternativ för grisbesättning :
The purpose of this report was to compare two different options for expanding of an
existing pig farm. For the time being there are low prices within the agricultural market
of pig production, and it is interesting to see if it is worth expanding or not.
The two different options this report is based on are: expanding from a herd with 50
sows in breeding gilt production to a herd with 100 sows in breeding gilt production
(option 1), or expanding to a herd with 140 sows in breeding gilt production (option 2).
The number of pregnant gilts produced per year will stay the same for both alternatives;
about 300 pregnant gilts per year. The rest of the breeding gilts will be sold at a weight
of 25 kg. The pigs that are not sold as breeding gilts (e.g. castrates, and female pigs that
are too small or that have disorders) will be kept on the farm as growing-finishing pigs
until 120 kg of live weight, and then sold to the slaughter house.
By using the existing buildings, even after the expanding, the investment costs, and
thereby costs for housing, were kept as low as possible.
Förstudie för en vindkraftpark på Malmölandet i Norrköping : En undersökning av förutsättningarna för en vindkraftpark på ett sen tidigare planerat område
This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.
