Social preference and diet learning in goat kids at pasture

AbstractHerbivores can be classified into either hiders or followers depending on their postpartum behaviour. The two behaviour types affect the spatial relationship between the mother and her infant. Goats are seen as hiders, although the environment plays a central role when it comes to the behaviour. Therefore, in the first part of this study the aim was to investigate how the goat kids? spatial relationship changed in the transition from indoor housing to pasture.

Selen och incidens av typ 2-diabetes - en systematisk översiktsartikel

Background: Type 2 diabetes is a disease which causes vascular damage, stroke and premature death.Oxidative stress may play a role in the development of insulin resistance and diabetes. Selenium is amineral involved in the protection against oxidative stress, and has been thought to be favorable in theprevention of the disease. However, this has changed since trials observed positive correlationsbetween high selenium levels and incidence of type 2 diabetes.Objective: To examine the studies that investigates seleniums effect on the incidence of typ 2 diabetesSearch strategy: Searches have been done in PubMed and Scopus.Selection criteria: Included studies were human studies in English/Swedish with RCT or cohortdesign with the aim to investigate the correlation between selenium and incidence of type 2 diabetes.Excluded studies were studies whose aim was to investigate the role of selenium in patients withexisting diabetes. Studies regarding pregnant women, animals or children and with in vitro design werealso excluded. Of the studies found in Scopus where MeSH terms were available, the ones who did notinclude relevant terms were excluded.Data collection and analysis: Studies were collected according to the aforementioned criteria.

En utvärdering av avelsprogrammet mot kronisk hjärtklaffsdegeneration hos Cavalier King Charles spaniels :

Chronic valvular disease (CVD) is the most common cardiac disease in dogs, which account for 75% of all the cardiac cases. Cavalier King Charles spaniel (CKCS) is the most affected breed and it´s 13th times more likely that a CKCS, between the age of 7-10 years, will die or be euthanized for cardiac disease, compared with other breeds. The prevalence has been proven to bee independent of coat color and weight but highly dependent on age and gender in CKCS. In 2001 the Swedish Kennelclub and the Special club for cavalier King Charles spaniel created a breeding program against CVD in CKCS. In this program dogs are not allowed to breed until 4 years of age and have to have a heart auscultation without murmurs.

Metabolism av mykotoxiner i våmmen

SammanfattningMykotoxiner är sekundära metaboliter som kan bildas av vissa mögelsvampar. Idisslare har generellt ett högre skydd mot mykotoxiner än vad enkelmagade djur har då våmmens mikroorganismer kan fungera som ett extra skydd mot mykotoxikos. Trichotecenerna deoxynivalenol och T-2 toxin bryts ner till de-epoxymetaboliter i våmmen genom att dess toxiska epoxyring spjälkas bort. Deoxynivalenol metaboliseras helt eller delvis av våmmens mikroorganismer, medan T-2 toxinets nedbrytningskapacitet inte är lika hög. Aflatoxin B1 har en låg nedbrytbarhet, och inga metaboliter har kunnat detekteras i våmmen.

Vaccinationsbiverkningar hos hundar i Sverige

Vaccinology is an ever expanding field. As a member of the veterinary staff it is important to stay up to date with the continuous new scientific data and recommendations that affect the care that our companion animals receive at the veterinary clinic. This paper presents adverse vaccination reactions, their cause, risk factors and suggestions how we can minimize the risk of adverse vaccine events in dogs. Dog owners in Sweden were allowed to answer a questionnaire about adverse events following vaccination. Lethargy, edema and pruritus were among the most frequently seen adverse effects.

Biodiversitet av evertebrater på vegetativa tak

In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.

Förekomst av Chlamydia/Chlamydophila spp hos gris med och utan konjunktivit.

ABSTRACTChlamydia and Chlamydophila are species of a family of bacteria (Chlamydiaceae) that cause a range of diseases, including conjunctivitis, in a variety of animals including pigs and humans. Some species cause zoonotic disease. This study examined the occurrence of Chlamydiaceae in samples taken from the lower eyelid conjunctiva in pigs with and without conjunctivitis. The study was initiated based on a herd investigation aimed to examine the experienced increase of conjunctivitis in some finisher herds. This study was conducted as a case-control study, by collecting samples from 62 case pigs (16-26 weeks old) and an equal number of controls, from three herds in Uppland, Sweden.

Fysiologiska effekter av lök : nyttiga eller toxiska?

Lökarterna som tas upp i denna litteraturstudie är främst gul lök (Allium cepa) och vitlök (Allium sativum), men också dagglök (Allium flavum). Syftet är att ta reda på hur farliga ämnena i lök är, om de negativa effekterna överväger de positiva, hur djurslagsskillnader ter sig, om det spelar någon roll hur löken är tillagad och vilka symptomen på lökförgiftning är. Eftersom det är många faktorer som avgör om lök får negativa eller positiva effekter är det svårt att säga om lökens effekter är endast positiva/negativa. Effekterna kan vara både positiva och negativa, det beror till största del på dosen men även djurslag och lökart spelar roll. Positiva effekter av lök har utvärderats i studier. Fenolerna har visats vara antioxiderande, antiinflammatoriska, antibakteriella och antifungurala, de flesta av dessa studier gjordes in vitro. Lökinducerad hemolys drabbar de flesta djurslag som får i sig för mycket lök men det finns de som är mer eller mindre känsliga.

Blandfoder i automatiska mjölkningssystem

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

Äppelpressmassa i Sydsverige - nuvarande användningsområden och möjligheter till nya produkter

Pomace is the solid remains (i.e. stems, pulp, seeds, and skins) after pressing for juice. The annual production of apple pomace is 593 000 ton worldwide. Its field of application depends on local conditions. In order to investigate the field of application of apple pomace in the Southern Sweden, six persons on companies with production of apple juice were interviewed.

Svampsamhällen och svampsjukdomar på åkerböna samt svamparnas inverkan på grobarheten

Broad beans are becoming a larger crop in Sweden. This is probably due to the current discussion about the cultivation of soya beans that are imported to be used as protein fodder. Broad beans are a good break crop in a small grain intensive crop rotation and works as a protein source for animals together with for example ley. At present little research has been done on broad beans and more knowledge is needed. This study is about fungal communities and diseases on broad beans and the impact of these fungi on seed germination.

Växters förmåga att ackumulera metaller : Vass, bredkaveldun och gäddnate i Bergviks dagvattendamm

AbstractSurface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one bigger has been constructed in order to decrease the pollutant pressure from the receiving waters of Kattfjorden. Several heavy metals are essential for plants and animals in low concentration but when they occur in higher concentrations, they become toxic to the organism. The larger pond at Bergviks shopping centre has a sedimentation function so the heavy metals sink to the bottom thereby not releasing directly in to Kattfjorden.

Vad ridskolor lär ut om hästens beteende

The horses have been in the care of humans for about 5000-7000 years. But even though the horses have been domesticated and artificial selected for such a long time their natural behaviours and instincts still remains. In the rich countries there are many people who have the opportunity to ride either on their own horses or at riding schools. Many of these people have not grown up on farms and have no experience of handling big animals. This can lead to implications of the horses? welfare.

Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity

Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.

Hästtransportsläp - krav, utformning och funktion :

SUMMARY The interest of horses in the riding sector has increased the last decades. A large amount of horses are transported in a 1 or 2-horse trailer, which is pulled by a car. Today a large number of different products and designs of trailers can be found on the market. The difference in shaping of trailers depends on tradition and experience. There are no detailed directions on the demands for shaping of horse trailers today. The literature review contains a market analysis of both Swedish and imported horse trailers.
