Analys av blått och grönt vattenfotavtryck för nötkött från ICA:s sortiment

ICA vill utveckla sitt miljöarbete i vattenfrågor. Denna rapport syftar till att öka medvetenheten hos ICA om verksamhetens miljöpåverkan genom att analysera vattenfotavtrycket ? vanligen kallat Water Footprint ? för ett livsmedel. Vattenfotavtryck är ett verktyg inom miljösystemanalys som används för att kartlägga sambandet mellan produktion och konsumtion av produkter och vattenanvändning. Studien visade att vattenfotavtrycken är ungefär 14 500 liter/kg och 16 500 liter/kg för svensk respektive irländsk nötfärs.

Artificiell insemination i dikobesättningar

Den vanligaste produktionsformen av nötkött sker i dikobesättningar, där kor och kvigor förväntas föda en kalv per år. I sådana besättningar är fertilitet hos djuren en viktig faktor, då förmågan att föda fram en kalv varje år påverkar inkomsten. I Sverige används naturlig betäckning i störst utsträckning, men ett alternativ är artificiell insemination. Syftet med detta arbete är att undersöka för- och nackdelar med artificiell insemination och varför det inte används i samma utsträckning inom dikobesättningar som hos mjölkkor, samt när det kan vara aktuellt att använda sig av. Den artificiella inseminationens påverkan på dräktighetsresultat varierar mycket i studierna, från 37 till 74 %, men det antyds att 50 % är ett gränsvärde där resultat över detta kan anses godtagbara. Ekonomiskt finns fördelar så som ökade kalvvikter och mindre förluster relaterat till kalvningssvårigheter, men nackdelar i form av ökade kostnader för veterinärtjänster och mediciner samt för arbete.

Storlommens (Gavia arctica) häckningsframgång relaterad till vattenkvalitet

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

Återhämtningsprocessen hos en svensk livsmedelsproducent efter ett allvarligt produktfel : En studie av Findus hantering av ?Hästköttsskandalen? under våren 2013

This study deals with a Swedish company in a food industry that got affected by product failure, which led to consumer trust crisis followed by media and was needed to be managed. Situation had a negative impact on company?s trademark, which acquired long recovery work by the company. Study is following a case example of Findus problems with having horse meat in their meat product that was supposed to contain beef meat. Study aims to research how the company dealt with situation, through crisis communication and recovery strategies.

FORL : Feline Odontoclastic Resorptive Lesions

This report was written in an attempt to summarize old and new theories and scientific results regarding FORL (Feline Odontoclastic Resorptive Lesions). Several different kinds of treatment are presented in this study. Among them teeth extraction and crown amputation seems to give the best long-term results. It seems clear that the domestic cat of today have no trouble digesting dry foods without their teeth. The most accurate way to diagnose FORL is by using intraoral dental radiology technique.

Jaktprov hos brittiska stående fågelhundar

In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures. Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.

Evaluation of indirect blood pressure measurement, plasma endothelin-1 and serum cortisol in clinically healthy horses

Equine metabolic syndrome (EMS) it?s a clinical condition that includes obesity, regional adiposity, insulin resistance (IR) and laminitis. A similar syndrome exists in human medi-cine, the metabolic syndrome (MS), were systemic hypertension also is a prominent fea-ture. The systemic hypertension seen in humans with MS is partly due to a vascular endo-thelial dysfunction with an enhanced endothelin-1 (ET-1) mediated vasoconstriction. There are indications that systemic hypertension might be a feature in EMS as well but if ET-1 is involved in the development of the systemic hypertension in horses is not known.

Sjukdomsfrekvens och utslagningsorsaker hos kor med 12 respektive 15 månaders kalvningsintervall

The incidence of many of the most common diseases in dairy cattle has been proven to be highest during the time closest to calving. It is possible that the current breeding strategy with 12 month calving intervals increases the risk for disease in dairy cattle, which is problematic concerning both animal welfare and for economic reasons. The economic incentives behind a calving interval of 12 to 13 months have mainly been based on milk- and feed- costs and no costs due to diseases or fertility disturbances have been included.The aim of this study was to see if a lengthening of the calving interval would result in lower disease frequency. The hypothesis is that cows with a planned calving interval of 15 months have a lower disease incidence than cows with a calving interval of 12 months due to less number of calvings. Therefore the difference in disease frequency should be larger when compared over a long period of time, such as over lifetime, since cows with a longer calving interval experience fewer calvings.The study was performed between August 17th, 1994, and January 24th, 2007.

Levande vikt vid olika åldrar och sambandet med bröstomfång och mankhöjd hos SRB och SLB :

Live-weight at different ages for Swedish Holsteins (SLB) and for the Swedish Red and White Breed (SRB), and the correlation to heart girth and height at withers. The aim of this investigation was to study the live-weight changes and mature weight for the Swedish Red and White Breed (SRB) and for Swedish Holsteins (SLB), and to estimate the correlations between body weight and body measurements such as heart girth and height at withers, respectively. The material used was from one of the experimental dairy herds (Jälla) of the Swedish University of Agricultural Science. It included recordings on 293 dairy cows with information from 7142 weight occasions and recordings on 275 dairy cows with information of 557 heart girth measurements and 560 measurements of height at withers. The registrations were done during 1993-2002. There was a large variation in live weight between cows in different ages and lactation stages.

Polisens utvärdering av farliga hundar enligt lag (2007:1150) om tillsyn över hundar och katter

Aggression is a normal part of a dog?s behaviour repertoire and has always been an evolutionary relevant behaviour. Even if aggression in some contexts is relevant, it is one of the most common problem behaviour reported by dog owners. It has been discussed if some breeds are more likely to show aggression and therefore should be banned. On the 1st of January 2008 a new act was enforced by the Swedish government giving the police force greater authority in decisions to apprehend and euthanize dogs if they after an appropriate evaluation of the dog?s temperament think it is necessary.

Artificiell insemination av får

AbstractThe purpose of this bachelor thesis is to describe the use of artificial insemination (AI) in sheep and discuss the possibilities for AI in Sweden. Male and female fertility, heat detection, semen handling and insemination techniques in sheep are described. Advantages and disadvantages of AI are discussed. In order to achieve genetic progress it is important with well planned and implemented breeding programs. The Swedish Sheep Recording Scheme and computer software from Elitlamm are the basis for sheep breeding in Sweden.

Höjdsättning av mark : faktorer som påverkar processen i markprojektering

The parasite Neospora caninum is an intracellular protozoa discovered in the late 1980s. N. caninum has an indirect lifecycle which means it needs a definitive host and an intermediate host. The confirmed definitive host for N. caninum is dog and the intermediate hosts are among others dog and cattle.

Urea som kvävekälla till växande ungnöt

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.

Djurskydd för paragrafernas eller djurens skull? :

The purpose with this thesis was to form an opinion of how the animal welfare in Sweden is experienced by both farmers and animal inspectors. A great part of this work consists of an inquiry concerning the south and the middle of Sweden. We sent the inquiries to milk and meat producers and to animal inspectors. The response was high, which indicates that this is a subject that affects many people. Our literature study is mostly made on the library bases LIBRIS and LUKAS. The facts we found there were directed towards animal experimentation and furred animal breeding. In order to compare with earlier results we used investigations that had been made by Riksrevisionen 2003. There is a difference in opinions about the new Swedish animal welfare agency that started first of January 2004.
