Ekologiskt uppfödda kycklingar : en jämförelse mellan två olika foder
Organic rearing of broilers is not a large production in Sweden. In order to create a sustainable yet efficient production of organically produced poultry meat, at a price that the consumers are willing to pay, much more knowledge is needed. It is therefore important to do more research on organic broilers under Swedish conditions. This report is aimed to be a base for further studies.
In the study 2000 broilers of the hybrid Ross 308 divided in to two equal groups. The broiler hybrids that are used in Sweden are selected for a high growth rate and are normally slaughtered at the age of 5 to 6 weeks, with a slaughter weight of 1.7-2 kg.
Optimalt mottagningsstall för kalvar : en fältstudie
A cattle producer that buys calves that are younger than six months to the herd should have a starter stable to prevent infection spreading in the herd. According to the Swedish animal welfare regulation there has to be a starter stable if more than 50 calves that are younger than four months are bought in yearly to the herd. The aim of the study was to improve the knowledge about bovine buildings and management of starter stables to obtain optimal weight gain and health of the calves. The hypothesis 1) The younger the calves are when purchased, the higher the calf mortality and 2) Purchasing calves from a high number of herds involves a higher risk of calf health problems and calf mortality were tested in the study. The objective of the study was to give advices by way of presenting ideal solutions of how a starter stable should be constructed and managed.
A field study was done during June to September 2008 to collect knowledge and experience from existing starter stables.
Sensorer och system i mjölkkobesättningar : en litteraturstudie
The trend in milk production is similar in Sweden and across the world; the farms are getting fewer but increasingly bigger. The costs for hiring workers are increasing, which results in more cows per animal keeper. Sensors can then be a great tool for keeping track of animals which need special attention. With a reported decreasing fertility, sensors that can detect oestrus even at low levels can be especially helpful in bigger herds to pinpoint the cows that may be in oestrus. The number of farms with dairy cows that install AMS, Automatic Milking Systems, are increasing, and that also increases the need for sensors to control milk quality and composition when there is no visual control of the milk by a milker before milking starts.For the sensor data to be useful you have to have software designed to analyze and interpret the data to get relevant information that the farmer can use.
Rörelsemönster och golvrenhet på två olika slags spaltgolv i lösdrift för mjölkkor :
About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.
Welfare impairment of lambs around weaning. Play and other behaviour indicative of affective state
The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.
Gestaltning av boendelandskapet i gränsen mellan stad och land : exemplet Norränga i Lund
This is a 20 credit Master thesis within the landscape architecture education at the Institute for Landscape Planning at the Swedish University of Agricultural Sciences at Alnarp.
Norränga is situated on the fringe of the city of Lund, east of the existing district of Linero.The city planning office of Lund municipality has come up with a ?in-depth comprehensive plan? for the exploatation of the eastern area of Lund. The plan concerns an area of 1035 square kilometre which contains at least 1500 nya buildings, two schools, primaryschools, stores and bus station for local bus traffic and the new bus line - Lundalänken. The townplan is inspired from the historical Square block city with defined street system. The municipality has visions of what the green areas should consist of.
Vedrötor i stadsträd : biologi, detektionsmetoder och förebyggande åtgärder
Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.
Gruppering av sinkor i stora besättningar
The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.
Implementation of renewable energy in the Republic of Moldova : society and landscape in transition
The Republic of Moldova, situated in eastern Europe and a former part of the Soviet Union, is now experiencing
a phase of transition in both society and landscape. They have hardly any fossil depots and
are currently dependent on Russian gas, with 97% of their energy needs imported. The new elected
government wants to move towards the EU and this is generally seen as the way to grow and reduce
poverty. Security in the energy sector is important and one tool is to increase the use of renewable
energy sources.
Through interviews, texts, and visits I have studied the implementation of renewable energies (RE) in
Moldova through a society development perspective. The study has aimed to investigate the sociotechnical
complexity of this subject and to discuss the potentials and way of dealing with the subject in
the specific cultural context of Moldova.
Stureholm - en herrgårdsträdgårds historia, utveckling och framtida skötselmål :
Stureholm Manor and garden is a relatively young farming unit on clay soil in the north
western part of Skåne, a province in Southern Sweden. Since the middle of the 19th century
the landscape has been actively cultivated and has been transformed from oak forrest into
farmingland of high efficiency.
The industrial era during the 19th and 20th centuries meant new posssibilites for cultivation of
these clay soils. With equipment like steam ploughs and the possibility to obtain fertilizers,
the harvest increased considerably. This increased prosperity provided estate Stureholm with
a beatuiful corps de logi, a manor.
The trends prevailing in Europe around the turn of the century 1800-1900 against the growing
industrialism, was turned into a artisan movement known as Arts and Craft. The Swedish
followers idealized our Swedish history and they took the turn of a national romantic
movement that later turned into neoclassicism.

Vindkraftens generationsskifte i Halland
Vindkraften expanderar allt mer i Sverige och årsproduktionen ökade till 6,1 TWh år 2011, vilket är en ökning med 74 % jämfört med 2010.De nya vindkraftverken som sätts upp idag är oftast av effektstorlekarna 2 000 ? 3 000 kW. De som restes tidigare är omkring 200 ? 600 kW. I Sverige finns det många vindkraftverk som har varit i drift under en längre tid, och det är flera som passerat sin tekniska livslängd på 20 år.
Scandinavian Farmers : företagets värde för ägarna DLG och Lantmännen
Parallellt med en stark tillväxt av lantbruket i EUs nya medlemsstater har, sedan halvtidsöversynen av den gemensamma jordbrukspolitiken, marknaden för insatsvaror stagnerat i Sverige. I Danmark kan skönjas en liknande utveckling bland annat genom en allt mer reglerad marknad för exempelvis handelsgödsel. Dessutom sker en kraftig strukturrationalisering hos tillverkarna av lantbruksförnödenheter.
Den största aktören på den svenska marknaden för insatsvaror till lantbruket är Lantmännen ek för. Motsvarande aktör på den danska marknaden är Dansk Landbrugs Grovvaresellskab a.m.b.a (DLG). Båda företagen är kooperativt ägda av lantbrukare i respektive land.
A value chain analysis for timber in four East African countries : an exploratory case study
This study is a value chain analysis for timber in East Africa. It was commissioned by Vi Agroforestry, a nongovernmental organisation registered in Kenya, Rwanda, Uganda and Tanzania engaged in a rural development program that involves promoting tree planting and enterprise development (Vi Agroforestry, 2012). The purpose of the study was to identify and describe common value chains for timber in the countries where Vi Agroforestry operated.
Value chain is a concept and a framework describing how to structure information regarding activities included in satisfying a certain customer need, e.g. procurement, logistics, transactions, production and marketing.
?Sumpighet och Vattensjuka? en centralmakts påverkan på ettlokalt landskap
The purpose of this study was to examine the goals, possibilities and rationales that could be found in the discussions concerning the digging of ditches by governmental subsidiaries in order to drain the peat bogs of late nineteenth century Sweden. A further aim was to look at the effect on the landscape on a local level i.e. Släthults moss in Bäckaby parish, Småland in the south eastern part of Sweden. In order to be able to explain the connections between politics and landscape changes in a local population and its deciding bodies, influenced by ideas, science and production, a quadruple helix model developed from a triple helix model by Björn-Ola Linér was used. As a model of environmental history, three step thought was used, borrowed from Donald Worster.
