Welfare impact of social breeding value and straw for growing-finishing pigs

Animal welfare is of increasing concern in present society. In commercial pig farming, animal welfare problems are common. One of the causes for these problems is the barren environment in which pigs are housed, which can cause oral manipulation of pen mates. Providing straw might be one solution to this problem. Another solution could be reached through genetic selection.

Spermaadhesiner i olika fraktioner av hingstsperma :

Breeding-induced endometritis in horses seems to be down-regulated by certain components in the seminal plasma. These components are most likely some of the proteins in the seminal plasma in the stallion ejaculate, the so-called spermadhesins. This study aimed to recognize these proteins and determine their quantities in different fractions of the ejaculate. Fractionated ejaculates from four stallions were used to determine the presence and amount of proteins by way of size-excluding chromatography. All former known proteins, except two, were recognized in this study.

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. .

Hypertrofisk kardiomyopati hos Maine coon katter :

Hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats. Maine coon is one of the breeds where the disease is overrepresented. Studies have shown that HCM is inherited as an autosomal dominant trait in Maine Coon cats. This finding has led to cardiac screening using ultrasound in the breed. The results of the screening are used in a national breeding program constructed to reduce the spread and incidence of HCM in Maine Coon cats.

Hovbroskförbening hos svenska ardennerhästen :

Ossification of the collateral cartilages of the distal phalanx has been studied primarily in cold blooded horses. The clinical relevance of this condition is unknown. Despite this fact, since 1939, all Swedish Ardenner stallions have had to be classified as being free from this ossification to be approved for breeding. Initially, palpation was used as a diagnostic method, but since 1982 radiology has been the only method used. The aim of this study was to assess the outcome of 68 years of breeding program. Dorsopalmar radiographs were taken of the front feet of 58 Ardenners (30 mares, 8 geldings and 20 stallions) and the ossification of the collateral cartilages was evaluated and graded according to three different scales; - Ruohoniemi (grade 0-5), - Swedish University of Agricultural Science (grade 0-3), - and a new scale (grade 0-3), developed for this study.

Från vilda till domesticerade djur - kan man gå ett steg längre?

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

Kunskap & strategi : En studie av strategisk kongruens mellan affärs- och kunskapsstrategi i managementkonsultföretag

This study examines how management consulting firms work with business- and functional strategy and how these strategies are interrelated. More specifically we focus on business strategy (business unit level) and knowledge strategy (functional level) and whether these are aligned or not, i.e. whether strategic congruence exists.A number of recent studies have examined the importance of business strategy and knowledge strategy in management consulting firms separately, but few have pointed out the importance of the alignment between them. With this study we contribute to the strategic field of research with a model that describes how management consulting firms should work with their knowledge strategy given their business strategy. The model is developed through a synthesis between theories in the field of strategic congruence, business- and functional strategies and thereafter tested by an empirical case study of six management consulting firms.

SATS + e2 = SANT? : en studie av SATS lednings kommunikationsstrategi då träningskoncernen förvärvade den dåvarande konkurrenten e2

Aim: The aim of this essay is to study the communication strategy that the company SATS developed before taking over the company e2. The following questions are to be answered: - what was the planned communication strategy before taking over the company e2? - did SATS follow their original plan when implementing this strategy? ? Which strengths and weaknesses of the communication strategy can be identified based on opinions of the employees?Material/Method: Together with literature and document studies, a qualitative method has been used and seven personal interviews have been conducted. One informant was selected due to professional position; the other six respondents were former employees of the affected company e2.Main results: The main results from the study show that the company SATS did in fact follow their plan very accurately with only some minor changes such as an earlier started education program and exclusion of an initially planned evaluation activity. Communication about the takeover of e2 to employees was quick and clear.

En flödesutjämnande driftstrategi för Uppsalas fjärrvärmesystem : En ändrad styrning av framtemperaturen

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

Den digitala strategin : En rapport om arbetet med en digital strategi för ett litet, nystartat företag

Social media, such as Facebook, Instagram and Twitter, have become popular platforms for social communication, and, increasingly, also important channels for business marketing. For a business intending to use social media for marketing, however, developing a strategy and building a trademark can be a challenge. This report describes how a small, newly established business enterprise can develop a digital strategy with clear goals and practical guidelines. The report describes a digital strategy for Gelato Scarfó and shows how this strategy is made concrete through a set of guidelines. The guidelines develop a trademark for identification and loyalty, and give advice on how new materials can be made consistent with the trademark..

Syringomyeli hos hund

The canine population has during it?s time with humans gone through at least 2 major genetic bottlenecks, the first when it was separated from the wolf, and the second when it was divided into different breeds. Among other things, this has lead to the accumulation of unwanted genes, such as genes causing disease in dogs. One such inherited disease is syringomyelia, which has proven to be more common than expected, especially in certain smaller breeds such as the Cavalier King Charles Spaniel. Syringomyelia in dogs is often a secondary condition caused by the malformation called occipital hypoplasia.

Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

Analys av dräktighets- och fölningsresultat inom svensk varmblodig ridhäst och svensk varmblodig travhäst åren 2000-2006

The purpose of this thesis was to analyze conception and foaling results of Swedish warmblood and Standardbred trotters using breeding statistics during the years 2000-2006. Key issues in this thesis were: Have the conception and foaling results of stallions changed during the period 2000-2006? What is the effect of the use of various breeding methods? Is testicle size correlated with conception and foaling results? How important are age, breed and level of inbreeding of the stallion for conception and foaling results? Breeding statistics were available for 537 Swedish Warmblood stallions and 305 Standardbred trotter stallions. To be included in the analyses, a stallion must have mated at least ten mares in total over the period 2000-2006. This criterion was met by 313 Swedish Warmblood stallions and 272 Standardbred trotter stallions.

Romernas situation i Sverige : En studie över vilka typer av integrationsstrategier som återspeglas i Svensk politik

The focus in this study is on the situation of Roma in Sweden. The purpose is to see the integration strategies that are reflected in Swedish politics, considering the inclusion of Roma. Idea analysis has been used as method, and I have analysed the text to find expressions of four different ideal types that represent four different types of integrations processes. The material consists of the government?s strategy plan for the Roma?s inclusion in Sweden between 2012-2032.

Phenotyping of Bali cattle and interviewing farmers in Indonesia - a minor field study

Among the Indigenous cattle breeds in Indonesia, the Bali cattle is the most preferred by small farmers. The Bali cattle is a beef breed, and is considered to have several advantageous characteristics and to be well adapted to the country?s harsh environmental tropical conditions with drought and rain. The main aim of this project was to phenotype of Bali cattle from different locations in order to identify and document diversity within the Bali cattle breed based on their observable characteristics, to compare cattle from different areas and production systems to see the effect of management on phenotype. In this study, 107 cows and bulls of the breed Bali cattle, from Kalimantan, Sumatra, Lombok and Bali were phenotyped.
