Wool loss in sheep

The idea behind this project came from a feed study executed two years during the lambing season. Both years Wool loss was experienced. Low temperature in combination with shearing was believed to cause the Wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of Wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for Wool loss and how common Wool loss is in Swedish sheep herds.

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.

Är merinokorsningar ett alternativi jämtländsk fårhållning?

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Barn med 22q11.2 deletionssyndromet ? hur hör de?

The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.

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.

Vilka strategier och metoder kan vara användbara för en hållbar viktnedgång?

The purpose of the study was to examine what methods and strategies individuals use to maintain their weight loss. Another aim was to explore which factors can complicate or simplify weight loss maintenance. Fifty-four individuals who had maintained their weight loss more than a year, participated by answering a questionnaire. The questionnaire was constructed and distributed through the internet. The answers were registered in the program google docs.  The participants mentioned successful methods and strategies, such as exercising regularly, the majority exercised 30 minutes at least five times per week.

Hörselnedsättning hos för tidigt födda barn ? En litteraturstudie

A stay in the neonatal intensive care unit of greater than 5 days is one of the identified risks ofa sensorineural hearing loss. Preterm infants usually have at least one risk factor for hearingimpairment. The period from 25 weeks' gestation to 5 to 6 months of age is most critical tothe development of the auditory system. We think it is important to investigate hearingimpariment among infants born preterm, degree and type of hearing loss, risk factorsassociated with hearing loss and how the auditory system may be affected by preterm birth.ObjectiveA critical review of the current literature including studies of preterm infants born betweengestonal age 25-37. Our aim is to identify the most common type and degree of hearing lossamong infants born preterm and if there is an association between hearing loss and pretermbirth.MethodA literature search of Scopus and Pubmed resulted in 16 articles from 2000-2015ResultsMost of the infants in this study had a severe to profound sensorineural hearing loss.

Traditionella och samtida bottenbj?lklag: med fokus p? isoleringsmaterialen

The survey aims to shed light on traditional and contemporary bottom floor frames, their construction and different insulating materials; mineral wool, wood shavings and charcoal. The purpose is to analyze and discuss the similarities and differences as well as the pros and cons with a focus on the construction and the different insulating materials. The work has been limited to comparing two different wooden floor frames. The first one is based on a real floor frame from an older building, this example is presented as the traditional floor frame in this study and are from around 1940. The other floor frame is presented as a contemporary floor frame and is based on wood building type descriptions and literature.

Kartläggning av allmänhetens attityd till hörselnedsättning och självskattad kunskap om hörsel ? en enkätundersökning

Objective: 1.4 million people in Sweden state that they are having problems with hearing and the majority havehad no contact with the hearing rehabilitation services. To have a hearing loss seems to be associated withseveral negative attributes. This could be due to bad attitude and insufficient knowledge on hearing loss intoday?s society.Purpose: The purpose with this study was to map the adult populations attitude towards hearing loss and selfratedknowledge of hearing with a survey.Methods: A web survey was made for this study. An official link to the survey was shared from two Facebookaccounts to a total of 997 contacts and a total of 247 responses were collected.Results: The majority of the respondents have estimated their general knowledge of hearing to fairly extensivefollowed by very small.

Hörselnedsättning bland diabetiker med typ 1-diabetes respektive typ 2-diabetes ? en jämförande metaanalys

Background: Diabetes mellitus is one of today's major public health problems, affecting up to 347 million people worldwide. Several studies have shown a correlation between hearing loss and diabetes mellitus. However, it is still unclear whether this correlation differs between type 1-diabetes and type 2-diabetes.Purpose: The purpose of this study is to investigate whether there is any difference in prevalence of hearing loss in type 1-diabetics versus type 2-diabetics.Method: A meta-analysis was performed based on ten studies that were identified through the database PubMed and through manual searching of references. Odds ratios for the risk of developing hearing loss were calculated in each study. Pooled odds ratios were calculated using a random effects model.Results: Pooled odds ratios indicates that both type 1-diabetics and type 2-diabetics are more likely to develope hearing loss compared to non-diabetic controls.
