Vinterlamning : en pilotstudie : vilka faktorer påverkar fruktsamhetsresultatet?
Under den senaste tiden har det svenska beteskravet varit omdiskuterat. Många lantbrukare ser beteskravet som ett problem och har löst det genom att endast erbjuda sina kor en liten rastfålla där de har tillgång till utevistelse och fysisk aktivitet. Syftet med denna studie var att undersöka deltidsbete i en besättning med automatisk mjölkning. Rastbete jämfördes med produktionsbete med avseende på mjölkavkastning, mjölksammansättning, foderkonsumtion och betesbeteende. Korna i båda behandlingarna (rastbete och produktionsbete) erbjöds bete under 9,5 h/dygn.
Rovdjursproblematik i Sverige med fokus på varg och får. Vilka lösningar finns?
The Swedish wolf population is like continue to grow and this will eventually lead to an increase in the predation of livestock. In Sweden carnivore attacks happen most frequent on Sheep farms and the majority of these attacks are performed by wolves. Because of this, the main focus in this study is on the Sheep and wolf problematic.
It is not only the direct killing of livestock that affects the animals and their owners in a negative way. It has also been shown that livestock that lives close to carnivores sometimes change their behaviour in a way that will affect their ability to reproduce and to forage efficiently.
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.
Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder
This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, Sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).
Samband mellan överlevnad, tillväxt och pälskvalitet hos lammen och fruktsamhet och modersegenskaper hos tackan
There are several factors influencing the profitability of production with Sheep. Two of the most important factors are ewe fertility and lamb survival. Also growth capacity of the lambs is important. This paper aims to review correlations between the ewe?s fertility and maternal behavior and lamb survival.
A screening for Schmallenberg Virus among sheep and goats in Tanzania
Schmallenberg virus (SBV) is a novel arthropod-borne orthobunyavirus emerging in Europe in 2011 to 2012. Acute SBV infection causes diarrhoea, fever and reduced milk production in dairy cattle, but it is mainly the reproductive disorders (abortions, malformed foetuses and stillborn animals) in ruminants that have caused substantial economical losses. The prevalence of the virus outside of Europe is poorly investigated. SBV or SBV-like antibodies were detected in Mozambique in 2013, which raised interest for a similar study in Tanzania.
In this study in Tanzania, blood samples were collected from 478 Sheep and goats from 39 herds in 15 different villages in three districts, covering areas in the north, south and east of Tanzania. The epidemiology of the virus was investigated by tracing antibodies by ELISA and mapping of the virus by PCR was started.
Bräkanden från förr : att skilja får från getter utifrån kv. Apoteket 4-5 i Visby
To differentiate between bones from Sheep (Ovis aries) and bones from of goats (Capra hircus) is a long lasting challenge for zoologists, archaeozoologists and osteologists. Especially considering archaeological remains which are often found fractured and poorly preserved due to taphonomic processes. Zeder & Pilaar?s (2010) and Zeder & Lapham?s (2010) methods of species differentiation has shown promising results when used on bones from modern Sheeps and goats. This paper aims to evaluate these methods by exerting them on excavated bones from kv.
Mulesingens historia och framtid, samt desskonsekvenser för djurvälfärden.
Mulesing is a surgical husbandry procedure performed on lambs in Australia. The reason is toprevent severe fly-strike to the breech area, which otherwise risks to be soiled with faeces.This problem is mainly occurring in Sheep of the Merino breed. Their fine wool is in demandworldwide due to high quality. Mulesing has been performed since the 1930?s, and eventhough alternative methods have been discussed nothing is yet generally accepted.

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.
A serological study of Rift Valley Fever virus in two regions in Tanzania
Rift Valley Fever (RVF) is a disease caused by Rift Valley Fever virus (RVFV), which is an arbovirus. An arbovirus is a virus that is transmitted by an arthropod vector, in this case a mosquito. The virus is a member of the Phlebovirus genus in the family Bunyaviridae. It was first identified in the Rift Valley in Kenya in 1930. The disease is a zoonosis but mainly affects domestic ruminants inducing massive abortions and a high mortality among young animals.
Betyg och bedömning : i en förberedelseklass år 9
Grades and assessment are a natural part in the school's everyday existence, deliberations about equivalent assessment is discussed all the time between teachers, students, home and school. They that in front are influenced of a grade or a judgement are in first hand the students and therefore are the important for the students to know which objectives and grade criteria that apply for them to achieve at the end of years 9. The aim with this survey is to get the knowledge about how a tutor grade family?s student in a preparatory class in stopped of years 9, in Swedish as a second language. Do the students in a preparatory class's get grades or a judgement? This is interesting also in order to know to which grade criteria students in a preparatory class have to achieve in the compulsory education?s later years and to know how a tutor assesses these students on the basis of those objectives and criteria that apply.
Produktion av finfibrig ull genom avel och utfodring - inkorsning av merino i sveafårsbesättningar :
To produce fine fibre wool as a complement to lamb meat production, Merino and Svea Sheep are currently being crossbred in the county of Jämtland. The aim of this study was to evaluate growth and wool quality of the first crossbred lambs. In addition, a literature study about nutritional effects on wool production has been carried out.
The literature study showed that fine fibre wool should foremost be achieved through directed breeding. Nutritional requirements of the Sheep at different stages of production should determine their feeding.
A screening for Schmallenberg virus among sheep, goats and cattle in Zambezia province, Moçambique : and preparations for a metagenomic survey of virus in mosquitoes
As the world´s population increases and people's living conditions are improving, larger areas are needed for houses as well as food production. This means that
new areas are exploited and that people, livestock, blood sucking insects and wild animals are forced to live close together. In combination with the global warming,
leading to extreme weather such as floods and storms, this allows both new and old pathogens to emerge. The number of "emerging infectious diseases", EIDs, has increased in recent years and many of them have their origin in poor, tropical countries. Moçambique is therefore considered to be a high risk area for EIDs.
Schmallenberg virus, SBV, was discovered in 2011 as an "emerging infectious disease" in dairy cows in Germany.
Corynebacterium pseudotuberculosis hos alpacka : utredning av ett utbrott i en svensk alpackabesättning
The alpaca is a camelid that originate from the South American highland. During recent years it?s been possible to keep alpacas in other parts of the world. Today there is a world-wide interest in alpacas, but there is still limited knowledge about this fascinating animal. There are approximately 350-400 alpacas in Sweden in 2007.
