Genes involved in ovulation rate and litter size in sheep

Fertilitetsegenskaper har ofta låga arvbarheter och selektion baserat på fenotyp är ofta ineffektiv och långsam. För att förbättra fertilitetsegenskaper som ovulationsmängd och kullstorlek hos får är det effektivast att selektera avelsdjur utefter deras genotyp. Olika mutationer i gener tillhörande transforming growth factor-? (TGF?) superfamiljen har visat sig påverka ovulationsmängd och kullstorlek hos får. Dessa gener är BMPR-1B, BMP15 och GDF9.

Prion infection of ovine cell culture with a natural Swedish scrapie isolate from 1986

Scrapie is an infectious neurologic disease in sheep caused by prions, corresponding to transmissible spongiform encephalopathies (TSEs) in other species. The prion is presumably constituted of PrPSc, the misfolded form of the normal endogenous prion protein, PrPC, which is found in practically all cells in the body. PrPSc can induce a conformational change in PrPC and misfold it as an imprint of itself; this is how prions amplify and spread. The process of conformational change is poorly understood and there might exist intermediate forms between PrPC and PrPSc. Bioassay using mice has traditionally been the golden standard in prion studies but is limited by cost and time.

Seroprevalence of Rift Valley fever in domestic sheep and goats of Gaza province, Mozambique

Animal welfare is of increasing concern in present society. In commercial pig farming, animal welfare problems are common. One of the causes for these problems is the barren environment in which pigs are housed, which can cause oral manipulation of pen mates. Providing straw might be one solution to this problem. Another solution could be reached through genetic selection.

In this research our goal is to conclude the aspects of interactivity which can prove to be important during the creation of a website. The focus in this essay is websites functioning as travelingguides, because we live in a time of traveling, experiance and learning. How can an analyzing method of websites be shaped? What can an analyze of interactivity on current travelingguides provide for recommendations by the creation of interactive travelingguides? The analyzingmethod is based on three shapingmethods and a poll that was answered by both national and international people. The analyze gave us quite clear results, if you follow the basics of Use Case, Personas, Usability and design, the website will have a bigger chanse of attracting people than if it doesn't..

Diurnal behaviour of cattle, sheep and goats on semi-arid pastures in Kenya

Studien genomfördes i Shompole i södra Kenya. I det här området är invånarna herdar som förlitar sig på kor, får och getter som sin enda inkomstkälla. De föder upp boskap under extensiva förhållanden, med naturligt bete som huvudsaklig födokälla för sina djur. Sex besättningar av den typen ingick i studien som genomfördes från mitten av december 2009 till mitten av februari 2010, vilket gav totalt 65 observations-dagar.

Att marknadsföra politik i Sverige : En fallstudie av tre svenska politiska partiers marknadsföringsstrategi gentemot yngre väljare

BackgroundPolitics in some ways has always been about communication and marketing. In Sweden some people believe that communication and meaningful relations with the voters are of no value, instead it is the political content that is of importance. Media evolution has changed the conditions of political marketing; this has meant that the choices of the right communication channels in political marketing have become more important today than ever. Political competition in Sweden has become more even in recent years, this has called for political communication and marketing to be more planed and well thought out. Political parties have therefore begun to spend millions on marketing themselves.

ST-läkares identitetsarbete: En studie av läkare under specialiseringstjänstgöring

The results from 13 interviews and one opinion poll answered by resident physicians were interpreted as stories about identity as primary material for this thesis. The resident physicians stress the importance of considering whether their work primarily concerns curing people from diseases or if the process of working with sick people also includes how to handle the pressure of work, either by adapting to it or changing it, and the search for balance between work and private life. Residents separate themselves from older physicians by saying that younger physicians accentuate empathy to a greater extent while older physicians emphasise a high work load. Identity seems to effect how the residents perceive and relate to their work, themselves as residents and different types of patients..

Verksamhetsstyrning i Stockholmsstad : En studie av verksamhetsstyrningen i Skarpnäcks stadsdelsförvaltning

This paper is a study of corporate governances in the municipal of Stockholm. The purpose of this paper is to enlighten the problems and opportunities for the corporate governances of the wards in the municipal of Stockholm.

Effekter av högt kaliumintag på magnesiumbalansen hos mjölkkor :

Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms. The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.
