This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed Grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.

Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..

Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.

Rabbits, Oryctolagos cuniculus, rapidly increases as pets. During the right circumstances, rabbits are friendly, social and playful. A rabbit who shows an abnormal behavior should always be examined by a veterinary, though there is almost always a medical problem. This essay is a result of a literature studie with the aim to find the prophylactic measures that may give pet rabbits a more healthy life. Rabbits have got a lot of common health problems, including dental, skin and gastrointestinal problems.

Examensarbetet ?Villa Sassi - ett gestaltningsförslag? redogör för tankar och processer under utformningen av det slutliga förslaget till trädgårdens utformning. Villa Sassi ligger i Lunds norra utpost, och förslaget tar hänsyn till platsen. Huset är ritat av arkitekt Heidi Sassi. De har själva byggt huset. Idag bor de i huset med sin familj. Arbetet inleddes med diskussioner med Heidi Sassi om hennes visioner för trädgården.

No summary of feeding recommendations for foals exists today, which is why this subject was chosen for a literature study. The aim of this study was to describe nutrient requirements of healthy full term foals and how the feeding should be designed to raise foals if they lose their mother. Mare milk composition changes during lactation to meet the requirements of the suckling foal. Foals are born with enzymes in their small intestine and the concentrations of these follow the consumption patterns of the foal. Microbes colonizes the gut as the foal becomes older and these changes cause foal diarrhea.

High-performance equine athletes have an energy requirement that often reaches twice the maintenance requirement. Horses are grazers and adapted to a grass diet, and diets high in grains and concentrates are associated with digestive upsets and behavioural disorders. It could therefore be of interest if the energy requirement of a high-performing horse could be met by forage. It is important that the forage have a high concentration of energy so that the horse is able to consume the whole amount of energy needed from the forage without exceeding the maximum voluntary intake. The purpose of this literature study was to investigate if the energy demand of a high-performance horse can be covered by forage produced under Northern Swedish climate conditions.

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

This study aims to create an understanding of how employees relate to directives that come from a level above them in the hierarchy and is to be implemented in their working activities. This is studied by examining a case where a work group has tried to implement orders, given to them by the government and through a work group in the level above them in the organizations, concerning how employees working with child health care is to educate parents regarding the child convention. The method that have been use in this study is group interviews with 19 child health care nurses and the two main questions that are asked is why has it been difficult to implement the orders and how have the child health care nurses expressed their resistance to the changes, this since only five of the nurses had begun working with the child convention. The theories that have been used focus on how resistance towards change is expressed, organizational incapability and reluctance towards change, as well as how grass root bureaucrats relates to change. The conclusion that can be drawn from this study is that it is important to let the concerned parties participate from the beginning of the process, to minimize their reluctance to the changing process.

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.

Upplands Väsby municipality has a vision that podcars in the future will become an effective alternative in public transport, with reduced car-dependency as a result. The system would also attract new inhabitants and businesses to the municipality.This report deals with various issues that podcar stations may face. Also, suggestions for possible track laying at the stations and station design are presented. Two areas are investigated. Eds allé which is a neighborhood that is planned for housing and where the station may be planned into the cityscape from the start.

Knowledge about feed racks for feeding forages to horses is lacking. Racks for sheep and cows are sometimes used for horses. Feeding roughage on the ground, or feeding silage bales with the plastic and net still on, can bring on a lot of different problems. The opportunity to control the hygienic quality is small and feed losses can be high. The purpose of this experiment was to investigate how the eating behaviour and consumption of horses were influenced by feeding racks of different constructions. Feed losses and changes in chemical composition of the forage were also studied.

The purpose of this study was to examine whether urea could be an option as a nitrogen source for young cattle, the study was limited to risks related to feeding, growth and feed efficiency. Microbes in ruminants have the ability to convert nitrogen to protein, this has been highlighted by beef producers as they are in search of cheap protein feed resources. Urea can be a worthy source of nitrogen for growing young animals, because of its high nitrogen content and the low price. Studies have shown that the replacement of a portion of the total protein content by urea in diets with low content of crude protein, like corn silage, may improve animal growth and feed efficiency. Replacement of all the true protein with urea can result in reduced feed intake and microbial growth.

The higher status homestead called Kullen is located on top of a small hill just outside of Hova in V?stra G?taland. The house stands on a plateau surrounded by a stonewall. Aerial photos from the 1960?s shows what looks like a big parklike garden behind the house, with a gravel walk cutting through on the length of the garden up to the house.
