Salmonellosis in Peruvian guinea pig production : a study to evaluate the prevalence of salmonella spp and importance of the disease

In Peru guinea pigs are raised for meat production and salmonellosis is considered as a major problem. Studies have detected salmonella in Animals with enteritis and pneumonia. Salmonellosis exists both in an acute and a chronic form. In the rural areas the diagnosis is made according to clinical signs and macro pathological findings at autopsy. The major systems applied for the guinea pig production are often classified as family, family-commercial and commercial. These systems differ in number of Animals and how industrialised they are.

Majsensilage i Sverige

Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.

Nötkreaturens val av betesvegetation på naturliga betesmarker :

This study concerns the type of vegetation selected by cattle grazing on semi-natural pastures, and whether the selection depends on the nutrient content of the vegetation or on other factors. The study was carried out in three different semi-natural pastures in the Uppsala area during June, July and August in 2006. The three pastures were first surveyed, mapped out and divided into sub-areas with regard to the type of dominating vegetation. The vegetation types identified were: wet, mesic, dry, wooded, pasture with signs of former cultivation (arable). Within each vegetation type three 1x1 m sampling plots were laid out. The grazing behaviour of the cows was recorded in a behaviour study.

When and what determines the death of an animal? A study investigating the heart activity during slaughter of farm animals

Slaughter of Animals should consist of two steps in order to be considered humane. The first step of the slaughter process is stunning, with the purpose of inducing unconsciousness and insensibility in the animal. The second step is exsanguination, which causes bleeding and eventually death. What death really means in these situations has been discussed intensively, but still no agreed definition has been accepted. Nonetheless, it is conceded that Animals are declared dead when consciousness is irreversibly lost, and absence of respiration and blood circulation are observed.

Impact of EU-regulation on pigs? welfare during transport

Each year 225 million pigs are transported within the European Union (EU) for slaughter, fattening and breeding. This results in poor animal welfare due to the fact that Animals are exposed to several numbers of stress factors in the vehicle during loading, transit and unloading. Animal welfare can be defined as how well the animal attempts to cope with its environment and during transport there is often severe difficulty for the pigs to cope properly. There is a growing societal concern for animal welfare. This resulted in that the European Union enacted a law called the EU-regulation with certain directives of how to improve the welfare of the Animals during transport.

Hägn i skogsbruket :

This survey was made during the autumn of 2002 and the beginning of 2003, on commission from the National Board of Forestry. The purpose with the survey was to gather experience and knowledge in the organisation about fencing and this was made through interviews. The ambition was also to get knowledge from people outside the organisation that have great experience of forestry and fencing. The interviews were based on questions that have been composed by the author with help from the supervisors. The questions were the same to both the personal from the National Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors. The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing Animals. The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.

The cow eye-Function and effect of light on milk yield

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the Animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

Is goat milk a better milk replacement to piglets, rat pups and foals than cow milk is?

AbstractOne opinion among people who are experienced in hand rearing newborn mammals is that goat milk is more suitable than cow milk if the young needs a milk replacer. The purpose of this literature review was to find out if there is scientific evidence that goat milk is a better milk replacer for piglets, rat pups and foals than cow milk. The milk is essential for the newborn animal, as its only source of nutrition until it has learned how to eat solid food. In this literature review, the composition of goat milk and cow milk is compared with the nutrient requirements after birth in piglets, rat pups and foals. The nutrient requirements and the milk composition are partly determined by the newborn mammals activity level and suckling frequency, which also is described.

Bevarande av svensk låglandsboskap

Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).

Genetisk variation i säsongsbunden reproduktion hos får

The purpose of this literature study was to describe the seasonal reproduction in sheep and the presence of genetic variation in fertility traits. Methods to induce oestrus are described and the possibilities to change the reproduction season through breeding are discussed. Sheep have a pronounced seasonality in their reproduction. Mating season starts in the fall and the lambs are born during the spring because this is the most beneficial time. The market request for lamb meat has increased and therefore it is desirable with ewes that could get pregnant all year round.

Advice Animals ? Onlinekulturens nya retorik : En stilanalys av postmodern kommunikation

Syftet med mitt examensarbete är att undersöka hur fem pedagoger på fem olika förskolor väljer att arbeta för att stärka det svenska språket hos barn som har svenska som andraspråk. Jag vill jämföra pedagogernas olika arbetssätt, och likheter och skillnader kommer att diskuteras. Syftet är också att fokusera på vilket förhållningssätt fem pedagoger har till barns användning av sina modersmål vid inlärning av ett andraspråk och hur pedagogerna ser på betydelsen av barns modersmål när barnen lär sig ett andraspråk. Jag har använt mig av en kvalitativ undersökningsmetod med intervju som datainsamlingsmetod. I resultatet framkom det att pedagogerna har en viktig och betydande roll för barnens tillägnande av ett andraspråk.

Echinococcus multilocularis in wild boar : aiming at an alternative surveillance method

This study was the first part of a larger project investigating a new surveillance method for Echinococcus multilocularis. In this study we examined livers from wild boar (Sus scrofa), looking for lesions caused by E. multilocularis. E. multilocularis is a small tapeworm which has an indirect life cycle.

Mellan makt och myt : om gravritual och brända ben från en småländsk vikingatida gravhög

For this essay, 12 liters of cremated bones from the Viking age grave mound RAÄ Berga 134:1 in Trotteslöv, Berga parish, Småland have been osteologically analysed.  The aim with this paper concerned questions as sex, age, number of individuals and animal species in the grave. Further questions that have been investigated are the relationship between the osteological sexdetermination and artifacts as well as which role Animals played in burial rituals and as grave goods.The grave contained a middle-aged woman and a number of sacrificed Animals: two horses, two dogs, three birds, a boar and a cat. The bones were fragile and very fragmented. One of the birds was determined as a bird of prey, and that together with findings of horses and dogs indicates hunting with bird of prey, an activity performed only by powerful and wealthy individuals.  The woman was buried in a mound of notable size, and with common grave goods for the time period: combs, beads, bronze and iron items. An unusual finding was textile which indicates high status. The number of sacrificed animal species also suggests that the grave belonged to a powerful individual. During the Viking age Animals generally played an important role in grave rituals and as items to be used by their master in the next life.

Fullfoder för får :

During recent years the use of TMR (total mixed rations) has increased in Swedish lamb production. For many years TMR has been used for cattle and hence the information and knowledge is vast, while the knowledge concerning sheep and TMR is more limited. The aim of this thesis is to present an overview of the scientific knowledge on the subject, and also to compile practical experience from sheep farmers using TMR. The thesis begins with a literature review where different aspects relevant to the usage of TMR are dealt with. It is concluded that there are differences between sheep and cattle that must be taken into account.
