Klöver i ensilage till suggor - effekter på reproduktion och produktivitet

The weather has been extremely rainy the last summers in Sweden. Because of the rain, a lot of harvested straw has been lost since it was too wet to store. When the pig producers couldn?t get enough straw to use as bedding, an alternative was requested. Silage is a realistic alternative to straw but since silage often contains clover, it may not be suitable to use in pig production since clover is rich in phytoestrogens.

Gene expression from a cold-treated Swedish isolate of Haemonchus contortus

Totally 84 differentially expressed mRNA clones from infective L3 larvae of the parasite Haemonchus contortus, a blood sucking nematode, were analyzed with single strand hybridization assay (SSH). Altogether 79 clones were sequenced, edited, and compared with proteins found via BLAST in GeneBank. The aim was to investigate gene expression and potential protein expression following storage at 5 °C for 32 weeks. mRNA was extracted from fresh and stored L3. The SSH derived products were cloned into E.

IgG mediated suppression of immunological memory

Apart from recognizing and neutralizing threats, antibodies also have the ability to regulate immune responses against their specific antigen. IgG administered together with erythrocytes is well known to induce >99% suppression. This has been used to prevent haemolytic disease in new-borns since the 1960's, but the mechanism behind it is still not completely understood. The effect on the primary response is well established, but its influence on induction of immunological memory is still heavily debated. In this study adoptive cell transfer of splenocytes to irradiated mice was used to survey the effect IgG has on induction of immunological memory without disturbance from the primary IgG response.

Refugia som metod för att minska utvecklingen av anthelmintikaresistens hos får

Anthelmintic resistance is a major problem in Sheep husbandry all over the world. One way toslow down the development of anthelmintic resistance is to keep part of the parasitepopulation in refugia (unexposed to drugs) which will maintain the genes for susceptibilitywithin the population. Climate, type of parasite and drenching regimes effect the size of therefugia. Dilution of resistant with susceptible parasites, targeted treatment and targetedselective treatment are all management strategies that employ refugia. Dilution is possible butcomplicated.

Foderhäckar till hästar i lösdrift :

Knowledge about feed racks for feeding forages to horses is lacking. Racks for Sheep and cows are sometimes used for horses. Feeding roughage on the ground, or feeding silage bales with the plastic and net still on, can bring on a lot of different problems. The opportunity to control the hygienic quality is small and feed losses can be high. The purpose of this experiment was to investigate how the eating behaviour and consumption of horses were influenced by feeding racks of different constructions. Feed losses and changes in chemical composition of the forage were also studied.

Ronningsgift

This thesis examines the Sheep shed called Ronningsgift, and its historical functions and geographical location. The study aims to make a comprehensive gathering of the existing knowledge and to shed light on new theories about the history of Ronningsgift. This is done through desk research including literature and archive search, as well as an investigation and description of the construction and materials, and an interview. Further, I got the opportunity to take part of the results of two C14 samples from Ronningsgift. The literature and archive search shows that the most common theory of the historical function is as a guest house (g?ststuga/h?gstuga) or more traditionally called, Malst?ue/Malsteuvu.

Könsselektering av spermier från lantbrukets husdjur

Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.

Knallskott. Böter. Förlust 3-0. : En bildanalys av medierapporteringen efter läktarincidenten i fotbollsmatchen mellan Syrianska och AIK 2011.

In the 2011th Swedish football league three games were suspended because ofbangers that exploded on the terraces. The first suspended match was played by Syrianska and AIK. We have performed an image analysis of two of Sweden?s biggest newspapers, Aftonbladet and Dagens Nyheter, to see how they reported fromthat incident. The reports from the first incident are important because the mediareporting from the first incident might have determined the attitude of the press and the Swedish football association (SvFF) towards the supporters for the remainder of the season.

Under Terra Novas Stenar : en osteologisk- & arkeologisk analys av ett bronsåldersröse på Gotland

This paper discusses an osteological- and archeological analysis of a cairn from the Bronze Age on Gotland. The osteological material consists of both burnt and and unburnt bones from both human and animal. The objective of this paper is to shed light on the individuals who were buried in the cairn. It is also to generate information about continuity in its use and patterns of distribution of the bones and grave-goods in the cairn. The osteological analysis show that a minimum of five human individuals is present in the osteological material.

I människans tjänst? : en studie om relationen mellan människa och djuroffer i gravar från yngre järnåldern

By examine cremated remains from graves dated to late Iron Age I wanted to find out what sorts of animals were placed in the graves. But also to see if the animal sacrifices had any connection to the Old Norse religion. The osteological material that were analysed were from both cremated humans and animals and had been dated to Viking Age. The material is from burial ground 59 at Laxare, Boge parish on Gotland. In addition to the human remains, the material contains bones from horse, cattle, Sheep/goat, pig, dog, cat, bear, birds and fish.

Hästars behov av socialt umgänge- En studie om hur hästhållare i Laholms kommun uppfyller hästars behov av social kontakt

The problem with keeping horses with to little social contact has come to attention in a new regulation that comes into effect august 1st 2009. It states that horses? need of social contact has to be accommodated. That?s why it feels important to try to survey the horse owners? awareness about the regulation and its present fulfillment.

Ruminants´production within agroforestry systems in rural Rwanda : production benefits and problems

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding Sheep and one group interview were conducted.

Vårlamm eller dikoproduktion i Dalarna : fallstudie

This study investigates a farm in Dalarna which includes 16 ha of farmland and 1, 7 ha of pasture. The purpose is to find out if it is possible to start an animal production in Dalarna. The study is set only to compare spring lamb production with nurse cow production. There are two buildings on the farm that can be used for this purpose. One is an old cowshed, and the other is an unused silo for silage with a roof on top. Both of the buildings are compared to every alternative in the calculations.

Brandgravar : Yngre järnålder i Broe, Halla socken, på Gotland : en studie i olika metoder, med fokus på kremeringen

This essay concerns the osteological cremated skeletal remains from Broe, Halla parish, Gotland of  The Late Iron Age.The focus of this essay is to determine the position of the corpse on the pyre, whether the cremated bones were crushed after or prior to the cremation and if the individual was buried in the pyre. In addition the species, age, sex and skeletal abnormalities of the bones in question will be studied.The result of the research has yielded that the cremated bones did not need to be crushed to result in the small fragment sizes. Crushing of the bones may have happened during the cremation, this conclusion has been drawn through the comparison of a pyre experiment were bone fragmentation is evident with cremated foxes, and dogs in the cremation graves from Broe. The construction of the pyre and the position of the corpse could not be determined through colouring and fragmentation of the bones.The human's were commonly buried in the pyre, and in some cases it is possible that the "grave" in fact is the remainder of a pyre. The species found are dog, horse, cow, Sheep/goat and bear.

The shift in forest and tree limits in Troms County - with a main focus on temperature and herbivores

To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.
