Antipredator behavior by the red-tailed guenon, Cercopithecus ascanius

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

The effects of two light programs on sleep in dairy cattle

Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

Genetic variation in local Swedish sheep breeds

Sheep have played a very important part in rural history. In Sweden there were many kinds of small native breeds, kept for their meat and fleece. Women cared for the flock that often had very little to feed on during the cold and sometimes harsh winter months. This meant that these sheep over time acquired special phenotypic properties depending on the environment they lived in, and easily fed compared to modern breeds kept for meat. Most of these sheep have since become extinct.

Renen och nötkreaturet, en jämförelse mellan två olika typer av idisslare :

The aim of this literature review was to make a comparison between the feeding requirements of Swedish reindeer (Rangifer tarandus tarandus) and meat producing cattle (Bos taurus) within farming. Reindeer are an intermediate feeding type; they have the ability to adapt to short term seasonal changes in food. They avoid eating fibre as much as possible and display highly selective behaviour while foraging. Adaptation to harsh environments with a limited amount of food has made reindeer dependent upon easily digestible food and consequently their digestive systems are less capable of processing plants with high fibre content. Herding is an extensive system which requires a significant amount of land and labour and describes the reindeer industry.

Hackelselängden beroende av skördemetod :

The conditions for a good silage process start with good wheather and choice of crop, then choice of harvesting machinery. The shorter and more mechanically treated crop, the better quality of the forage. (Pauly 1994). This study has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces.

Utvärdering - till vilken nytta? : En studie om hur utvärderingar användas och vad som gör dem användbara

Syftet med denna studie är att göra en metaanalys kring användningen av utvärderingen Aktiveringspolitikens Janusansikte. Utvärderingen har genomförts i fyra stadsdelar i Malmö inom ramen för storstadssatsningen.Fokus har legat på att undersöka om resultatet av utvärderingen Aktiveringspolitikens Janusansikte har använts i de utvärderade verksamheterna, samt vilka faktorer som påverkar användande eller icke-användande av utvärderingar.För att analysera vilken typ av användning som har förekommit har Carol H Weiss modell för användning av utvärderingsresultat används. Denna har kombinerats tre förklaringsfaktorer för att försöka förstå varför det sker eller varför det inte sker någon användning av utvärderingsresultat. Dessa faktorer är den personliga faktorn, den kontextuella faktorn och utvärderingsfaktorn.Undersökningen visar att användningen av Aktiveringspolitikens Janusansikte inte varit så utbredd i de undersökta stadsdelarna. Däremot framkommer det en generellt positiv inställning till utvärderingar.

The effect of a lowered light intensity at night on cow traffic and milk yield in automatic milking systems

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

Review of the litterature and an attempt to evaluate intake levels of iodine and selenium in dogs with and without lymphocytic thyroiditis

The prime aim of this thesis was to investigate whether high or low iodine intake during certain periods of life was, or was not a strong risk factor for the development of canine lymphocytic thyroiditis (CLT). And secondly, if a high or low selenium intake in a combination with high or low iodine intake also may have an influence on that risk factor. To investigate this, a dietary questionnaire was sent out to dog owners. The dogs were selected from an ongoing genetic study of CLT. The questions investigated brand and type of feed during different life stages (puppy, junior and adult) and also if there were any use of dietary supplements.

Forskningscirkeln och dess påverkan på historieundervisning i en mångkulturell miljö

Under två terminer har vi medverkat i en forskningscirkel på en grundskola som behandlat historieundervisning i en mångkulturell miljö. Forskningscirkeln startades i samband med att den aktuella skolan fick ett stort tillskott av elever med invandrarbakgrund. Det ena syftet med detta examensarbete är att synliggöra lärarnas syn på rollfördelningen inom den aktuella forskningscirkeln. Den rollfördelning vi syftar på är framförallt den mellan forskarna och lärarna, inte lärarna emellan. Det andra syftet är att se hur lärarna upplever att de påverkats av att medverka i forskningscirkeln, och då med fokus på historieundervisning i en mångkulturell miljö.

The importance of Yeheb (Cordeauxia edulis) for Somali livestock production and its effects on body tissues when fed to Swedish domestic goats

The influence of active bomas on habitat choice of the common warthog (Phacochoerus africanus)

The common warthog (Phachocoerus africanus) is a relatively long-legged pig with noticeable curved tusks, a short neck and three pairs of facial warts. It has four recognized subspecies. The common warthog is a non-migratory ungulate living on the African savannah. It is a hindgut fermenter and predominantly dependent on high-quality foods. It prefers open areas for grazing but use bushes for cover.

Jämförelse mellan renskötsel och betesbaserad fårskötsel

This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.

Mötet med lärare : - En studie om elevers upplevelser av lärares påverkan av självkänsla och självförtroende

This study is about how students view the effects teachers have on their self-esteem and self-confidence. The theoretical background covers the consequences of success and failures, and the interaction between students and teachers, in regards of self-esteem and self-confidence. The purpose of the study was to examine what had in-fluenced the students? self-esteem and self-confidence in the interaction with teachers. To reach the goal of the study, several qualitative interviews were made with the following questions as base:? Which factors does the student consider to be of importance for their self-esteem and self-confidence in the interaction with teachers?? How does the student feel that these factors were affected concerning their self-esteem and self-confidence?During the analysis and systematization of the transcribed interviews, five factors emerged that effects self-esteem and self-confidence.

Lungmask och löpmagsnematod hos nötkreatur

Infection with intestinal parasites can in many cases be the reason for decreased performance or production. The gastro-intestinal nematode, Ostertagia ostertagi, and the lungworm, Dictyocaulus viviparus, are the most pathogenic nematodes of cattle and severe infection can lead to death. They have both a direct lifecycle and on the pasture the parasites spread as freeliving worms. The parasites are mainly a problem for the first season grazers. They have not developed immunity against the parasites and are therefor more sensitive to parasite infections.
