Kaninen som produktionsdjur

The purpose of this report was to obtain an overview of rabbit meat production in the world, in terms of breeding and feeding. It examines how different feed components contribute to the health of the rabbit as well as the quality of the carcass, and the breeding strategies that are most common in the major producing countries. The production of rabbit meat in Sweden is at present not very large, but it is gaining ground, and that is why this paper mainly deals with the rabbit production abroad. This report also examines the disease Rabbit Viral Haermorrhagic Disease (RVHD) in Sweden, where this disease can cause big problems. The rabbit (Oryctolagus cuniculus) is very special, both in its reproduction and digestion. There is no specific mating Season and the digestive tract is designed to digest forage efficiently.

Förändring av nitratläckage och växtproduktion från låglänt jordbruksmark vid en ny reglering av vattennivån i Mälaren

The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during Seasons, while the annual mean waterlevel will remain the same.

"Så nära men ändå så långt borta" : ? en studie om hållbar destinationsutveckling på Sandhamn

Sustainable destination development has in recent years become an increasingly important concept for tourism destinations. A destination must take into account the environment if it wants to continue being a successful tourism destination in the future. This essay investigates what needs to be developed on theislandofSandhamnfor that the destination can be more attractive in the off Season and how the players on Sandhamn integrate to develop Sandhamn in a sustainable manner. One market research and interviews with five different players were made. Through these interviews grew an understanding for how the cooperation between the municipal and the private party looks like and how the history of Sandhamn is the foundation for the islands tourism development.

Klimatfaktorers inverkan på granbarkborrens svärmningsintensitet i Medelpad

The spruce bark beetle (Ips typographhus) is one of the 25 000 species of insects in Sweden, an insect of great economic importance because it can alone terminate forest of high value. During the past decade, insights of climate change received with increasing attention. If the future brings a milder climate in the north and therefore a longer growing Season, one would think that it would only affect the forestry to the better? Yet in recent time, outbreaks after storm felling seems to occur more frequently. The Spruce bark beetle ruins millions of cubic meter of Norway spruce (Picea abies) in Sweden alone, with more frequent storm felling and a larger amount of wind thrown threes in the forests there will also be room for an advancing reproduction.

Grazemore DSS för att optimera utnyttjandet av bete i mjölkproduktionen :

The aim of the study was to investigate if the Grazemore Decision Support System (DSS) is able to provide a grazing management strategy that gives a high utilisation of grazed grass in milk production in the north of Scandinavia. To do this, a grazing experiment was planed and performed during the summer 2005. Simulations in the DSS were run to get a suggestion of how the cows should graze, grazing calendar 1. Deviations and updates during the Season resulted in the simulated grazing calendar 2. During the experiment, the actual milk yield was recorded twice weekly. The difference between actual and predicted milk yield by Grazemore DSS was analysed statistically with regression analysis and the mean square prediction error (MSPE) was estimated.

Vattensork och åkersork - skadegörare i svensk fruktodling

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter Season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

Underlag för BREEAM-certifiering : Kristianstad Nya Galleria

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Nya träd för stadsmiljö

Trees in urban environment are exposed to extreme conditions, foremost the ones that grow in the hard packed soil along our streets. They are also exposed to damaging insects and fungal diseases both local and new ones spreading from South Europe. The global warming with warmer temperatures provides a longer growing Season, making it easier for insects and fungus to establish a habitat. Based on these facts new tree species need to be available for future urban plantings.To determine what these trees would be an interview study began. Six people were selected who have experience in the field of urban environment planting.

Vårlamm eller dikoproduktion i Dalarna : fallstudie

This study investigates a farm in Dalarna which includes 16 ha of farmland and 1, 7 ha of pasture. The purpose is to find out if it is possible to start an animal production in Dalarna. The study is set only to compare spring lamb production with nurse cow production. There are two buildings on the farm that can be used for this purpose. One is an old cowshed, and the other is an unused silo for silage with a roof on top. Both of the buildings are compared to every alternative in the calculations.

Samband mellan överlevnad, tillväxt och pälskvalitet hos lammen och fruktsamhet och modersegenskaper hos tackan

There are several factors influencing the profitability of production with sheep. Two of the most important factors are ewe fertility and lamb survival. Also growth capacity of the lambs is important. This paper aims to review correlations between the ewe?s fertility and maternal behavior and lamb survival.

Åre kommun och klimatförändringar : En studie kring hotet mot Åre kommuns vinterturism och dess anpassning till framtida klimatförändringar

Today?s climate research shows that the climate may increase its temperature. One sector that is being threatened by global warming is the winter tourism of the Swedish municipality A?re. Tourism is an important economical source of income in A?re and is now threatened by a shortened winter Season.

Inventering av vecklare i Svenska äppelodlingar

Over the last couple of years, growers, researchers, advisors and plant protection companies have noticed increasing problems with tortricids in Swedish apple orchards. Since the insecticide Gusathion (azinphosmethyl) has been banned (end of 2008; KemI 2008), a further increase of tortricid populations can be expected. In order to get a picture of species composition and population densities among the tortricids, an inventory of seven species, Adoxophyes orana, Archips podana, Archips rosana, Cydia pomonella, Hedya nubiferana, Pandemis heparana and Spilonota ocellana was made in 11 orchards in southern Sweden (Skåne) in 2008. Population densities were estimated by bud sampling (April 20-25), pheromone trapping (May 5-September 22) and assessment of fruit damage (September 9-12). In all orchards A.

The shift in forest and tree limits in Troms County - with a main focus on temperature and herbivores

To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.

Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.
