Nutrient efficiency in Swedish dairy cows fed total mixed rations or partial mixed rations

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Hur påverkar rörelse barns prestation i skolan?   How does movement affect children?s performance in school? : How does movement affect children?s performance in school?

This report is a qualitative interview study which central content enlightens how movement and sports effects children?s performance in school. With the help of five different teachers in three different schools questions like; how does movement effect the performance of children in school? Have been answered.Lots of research and litterateur shows that children is doing better physical and mental, the concentration level is improved and the performance in school is better when exposed to more movement, also there are less conflicts and the students gets better motor skills.Comparison with the ?Bunkefloproject? has been done, which was a project in the south of Sweden where they let the children have physical education every day and then they examined how this effected their performance in school. With this basis this report will examine the teachers view on the subject.The result shows that the teachers think that there should be more movement in the daily schedule for the children because they seam to be more happy and concentrates better after movement.

Lärandemiljöns betydelse för barn i koncentrationssvårigheter The importance of the learning environment for children in concentration difficulties

Syftet med arbetet är att beskriva ett antal pedagogers uppfattningar om lärandemiljöns betydelse för barn i koncentrationssvårigheter samt vilket stöd de önskar av specialpedagogen. Undersökningen bygger på tio intervjuer med pedagoger från två kommuner. I detta arbete vill vi ge en bild av hur dessa pedagoger tänker kring lärandemiljöns betydelse för barn i koncentrationssvårigheter, hur de arbetar samt vilket specialpedagogiskt stöd de anser sig behöva. För att få en teoretisk grund redogör vi först för den litteratur vi utgått ifrån samt den teori som vi tror är aktuell för vårt arbete. Sammanfattningsvis kan vi konstatera att pedagoger är medvetna om att lärandemiljöns utformning är av stor betydelse för barn i koncentrationssvårigheter. Samtliga pedagoger upplever att de stora barngrupperna påverkar problematiken för barn i koncentrationssvårigheter.

Nyckeln till den positiva spiralen - En studie av musikers syn på sitt övande

Title: The key to the positive spiral - A study of musicians views of their practicing. The purpose with this paper is to make clear how continuous practicing on one element affects not just the specific part but also other things. Is it possible to find a positive spiral where everything can be better if you focus your practicing on one thing? Can this element if it is done daily in a qualitative way transform to a key which will help you to unlock the door to the positive spiral? Are there more keys to find? I am going to reflect my ideas in this paper through a philosophical, psychological and the brain sciences perspective. Quality in action is going to be compared with the quality that you need to set a successful goal, and to reach the state of mind called flow you will need both these qualities.

Böklåda med torv på rastgårdsytan i ekologisk slaktsvinsproduktion : effekter på beteende och emission av kväve (NH3 och N2O)

In organic animal production, synthetic amino acids are not allowed. Therefore, a higher level of crude protein is needed in the diet to pigs, which lead to more nitrogen (N) excreted in the faeces and urine. N can be emitted to the air in the form of e.g. ammonia (NH3), which contributes to eutrophication and acidification and as nitrous oxide (N2O), which is a very potent greenhouse gas. The emission of N can be reduced by e.g.

Attributanvändande vid sagostunder på folkbibliotek

The purpose of this Masters thesis is to investigate what attributes were used in story-time activities, why attributes were used in story-time activities and what functions they have. The study is based on qualitative methods in the form of a literature studies, observations and interviews. The interviews were undertaken with two storytellers from the same public library. The story-time activities were adapted for children from three to six years of age. The study suggested that there was a connection between story-time activities and a social and cultural perspective.

Riskbedömning och naturligt producerade dioxiner

The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.

Bekämpningsmedelsrester i dricksvatten : En undersökning av bekämpningsmedel i 50 enskilda brunnar i Laholms kommun

AbstractThe knowledge about pesticide residue in private wells is not well documented in Sweden.Previous studies have detected pesticide residue in private wells, this issue is what made themunicipality of Laholm commission the study. The purpose was to collect water samples from50 private wells in Laholm and have them analyzed for traces of pesticides. The wells in thestudy are spread geographical over the entire municipality. The analysis of the water sampleswas carried out by the accredited laboratory Eurofins. Nine of the 50 wells in this studycontained residue of pesticides and two of these exceeded the allowed concentration of 0,1 ?g/l.Nine different pesticides were detected, among these were BAM, Atrazin and breakdownproducts from Metribuzin.

Massbalansmodellering av fosfor i ett åländskt kustområde : en utredning om lokaliseringen av Lotsbroverkets utloppsledning

This report is commissioned by the Water and Sewage Agency in The City of Mariehamn, Åland. The basic aim is to investigate positive or negative effects of a relocation of the sewage pipe from a wastewater treatment plant, Lotsbroverket. The environmental licence of Lotsbroverket is to be revised and The Environmental Appeal Board at Åland?s Government and Administrative Board has made demands that several possible locations in an outer water area should be examined. The present location of the sewage pipe is in Svibyviken, which has been classified as an ?inner water area?.The objective of this work is to study to which extent the nutrient loading from Lotsbroverket influence the environmental conditions in Svibyviken, and to investigate the suitability of different locations of the wastewater pipe from Lotsbroverket.The way a coastal area looks, i.e., its morphometry, determines to a large extent its ecological characteristics.

Undersökning av luftkvaliteten vid småskalig biobränsleförbränning i två kommuner med modellsystemet VEDAIR

An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced.According to the result, there are areas with poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 µg/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Vid vilken glukosnivå frisätter kor insulin? :

Six cows were subjected to an intravenous glucose tolerance test (GTT) to evaluate the amount of glucose that is needed to stimulate the release of insulin from pancreas. Four of the cows were in early lactation and two were non-lactating and not pregnant. Series of blood-samples were collected to analyze the concentration of insulin and glucose in the blood. The cows were given lower levels of glucose than have been used in earlier glucose tolerance tests. The levels of glucose given were 7,5 mg/kg BW, 15 mg/kg BW, 30 mg/kg BW and 50 mg/kg BW.

Vallfoderproduktion i norrländskt klimat till högpresterande hästar :

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.

Kortare sintid ? hur påverkar det kons mjölkavkastning, metabolism, hälsa, hull och vikt?

A shorter dry period length has in studies abroad showed some positive effects among high yielding dairy cows. Among other things it has been suggested that the periparturient metabolic stress becomes lower, that the fertility is improved and dry off becomes gentler for the udder, due to a lower milk yield. The milk yield is generally reduced during the first period after calving, especially among primiparous cows. The aim of this master thesis was to investigate how Swedish cows were affected by a shortened dry period, regarding milk yield, metabolism, health, body condition and body weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined.

Lokal konservering av bok med mögelskador Förstärkning med Klucel® G

The aim of this paper is to make a plan for local treatment with Klucel® G of a book with moulddamage. The biggest problem concerned handling the book without loosing fragments and tohandle pages that were stuck together. In some places as many as six pages where stuck togetherand it was not possible to separate them without loosing material or breaking them. The otherproblem concerned the use of waterbased adhesives that might cause tidelines and paperdistortions as seen in another volume. The use of Klucel® G dissolved in ethylalcohol functionedvery well as strengtheners and also as an adhesive for lamination.

Equine metabolic syndrome

Obese horses with insulin resistance are often also afflicted with laminitis. Horses with these symptoms are given the diagnosis equine metabolic syndrome (EMS). Signs of insulin resistance are excessive accumulation of adipose tissue on the neck, around the withers and on the dorsal area of the hindquarters. Insulin resistance means that the function of insulin is defective and does not stimulate glucose uptake by the cells in the body in the correct way. This will result in an increased insulin release.
