Jordbruk och mjölkproduktion med kor i Etiopien :

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

Mjölkböndernas åsikter om VikingGenetics nya produkter X-Vik och GenVik

VikingGenetics is one of the world's largest breeding companies. 2008 was launched two new products, X-Vik and GenVik. Now VikingGenetics want to get information about the effects of the marketing. We have investigated the differences in knowledge and use of the products between different livestock associations, size of herd and farmers' breeding interests. The method used was by sending out a questionnaire by mail.

Importance of epigenetics in animal breeding : genomic imprinting

ABSTRACTThe aim of this study was to give an overview of the evidence for genomic imprinting in livestock and other mammals as well as outline the potential use of gene imprinting in livestock breeding. Epigenetics is the mitotical and meiotical partial hereditary variation in genomic activity without any alterations of the DNA sequence. An example of epigenetic regulation is genomic imprinting where one allele?s expression differs depending on which parent it was inherited from. These parent-of-origin effects are currently overlooked in livestock production.

Köttkonsumtion och svält : Finns det ett samband?

Min utgångshypotes var att en minskad köttkonsumtion ger en minskad boskapsuppfödning. En boskapsuppfödning som idag tar i anspråk ca 70 procent av all jordbruksmark och 40 procent av den globala spannmålsproduktionen.Tanken var att en minskad boskapsuppfödning skulle bidra till en ökad tillgång på spannmål för människor och därmed en minskad svält. Men sambandet mellan svält och jordens resurser var inte så enkelt som jag hade förespeglat mig. Maktkoncentrationen som återfinns i matens distributionsled visade sig ha satt spelreglerna om tillgång och efterfrågan mer eller mindre ur spel. En ökad tillgång på mat genom en minskad köttkonsumtion och bättre resurshantering verkar därför inte påverka fattigdom och svält nämnvärt.Den nuvarande världshandeln visade sig också vara en bidragande orsak till fattigdom och svält då mat från nord, producerad med hjälp av statliga subventioner, konkurrerar ut lokalproducenter i syd.

Kannibaler och veganer : avstånd och gränsdragningar i köttets värld

There are several ways in which people can relate to eating or not eating animals. This essay is focussing two main strategies: Making distances and drawing borders.Today, there are several reasons for not eating meat, including environmental reasons, individual and public health reasons, ethical reasons and more. Yet, people eat more meat than ever. According to the UN, this is a major problem. In 2006 the report Livestock?s long shadow pointed out that meat consumption was a bigger problem from an environmental point of view, than global transports, including air-traffic.

NUDGING Kan nudging leda oss till att äta mer klimatsmart - Ett empiriskt experiment på IKEA med syfte att få restauranggästerna att äta mer vegetariskt

Food consumption generates externalities such as carbon dioxide emissions, which contribute to global warming. The principal issue is that emissions are not covered by the "polluter pays principle". For this reason, new policy instruments need to be tested and implemented to correct the externalities. In food production, beef and dairy production has the largest environmental impact in terms of carbon emissions. As food is a necessity, simply reducing production will not solve the problem.

Brucellosis in small ruminants : an investigation of knowledge, attitude and practices in peri-urban farming around the region of Dushanbe, Tajikistan

Landlocked Tajikistan is situated in Central Asia and is not only the smallest republic of Central Asia, but it is also one of the most mountainous with some of Central Asia?s highest peaks. Tajikistan is currently and historically the most financially disadvantaged country within Soviet Union/Russian territories. Agriculture is the main occupation for more than half of the country?s population. Unfortunately, however, only 7% of Tajikistan is arable land and the agriculture productivity is low.

Genomisk selektion och uppbyggnaden av avelsprogram hos mjölkkor

During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.

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.

Vegetarisk kost - om sjuksköterskors kunskaper. En empirisk studie.

The purpose of our study was to establish whether the knowledge about vegetarian diet was enough among nurses in order to practise professional nursing. We made an empirical study based on a questionnaire. Twenty-one registered nurses answered the questionnaire that consisted of mostly open questions. The result showed that almost everyone experienced that they gave dietcounselling and many nurses mentioned that dietcounselling was important. The majority of the nurses thought that they had enough knowledge to be able in order to deliver a fundamental dietcounselling but nobody considered that they knew much about vegetarian diet..

Vegetarisk kost - ett möjligt behandlingskomplement för symtomlindring vid reumatoid artrit?

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: A vegetarian diet, a possible treatment complement for relief of symptoms ofrheumatoid arthritis? A systematic review.Author: Alexandra Ahlsén and Caroline ForsbergSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background: Rheumatoid arthritis (RA) is a chronic remitting polyarthritis that is relapsing.Symptoms are inflammation of the joints with pain, stiffness and degradation of joint tissue.In some cases, also other parts of the body are involved. The treatment consists ofmedications to reduce pain, inflammation and degradation of joint tissue. Today, the offerednutritional treatment is primarily focused on meeting energy requirements and nutrient needs.The diet has also been discussed as symptomatic treatment, and one of the factors believed toinfluence the symptoms is meat.Objective: To assess the evidence as to whether a vegetarian diet affects the symptoms ofrheumatoid arthritis, and if so, to suggest how it can be implemented in practical dieteticswork.Search strategy The databases used in the literature search was PubMed, Scopus, and AMED.The search words used were: "rheumatiod arthritis", "vegetarian", "vegan", "diet", "meat" and"animal protein".Selection criteria: Studies investigating a vegetarian diet on the symptoms of RA wereincluded. Only RCT, clinical trial, controlled clinical trial, human studies and original articlesin English or Swedish were included.

Hur ska vi komma vidare? : frågor rörande neolitiseringen i Sydskandinavien

This paper deals with the question of neolithisation of Southern Scandinavia. The main goal is to give an overview of three theories regarding how agriculture and livestock breeding was introduced to the Southern Scandinavia. These are as follows: the immigration theory, the socio-economic theory and the historical explanation theory. Furthermore it is investigated which theory has the most probably support in material culture. There are obvious difficulties in interpreting the archaeological material.

Crossbreeding in dairy cattle

The aim of this literature review is to give an overview of the differences between pure- and crossbreeding systems. Crossbreeding is a mating system with individuals of different lines or breeds. It is one of several breeding strategies in dairy production used to increase the economic profit. The use of crossbreeding increases due to changes in the dairy market and an increase of inbreeding among purebred Holstein. The main benefit of crossbreeding is heterosis, which is the improvement in genetic level in a hybrid offspring above the average of the parent breeds.

En utvärdering av avelsprogrammet mot kronisk hjärtklaffsdegeneration hos Cavalier King Charles spaniels :

Chronic valvular disease (CVD) is the most common cardiac disease in dogs, which account for 75% of all the cardiac cases. Cavalier King Charles spaniel (CKCS) is the most affected breed and it´s 13th times more likely that a CKCS, between the age of 7-10 years, will die or be euthanized for cardiac disease, compared with other breeds. The prevalence has been proven to bee independent of coat color and weight but highly dependent on age and gender in CKCS. In 2001 the Swedish Kennelclub and the Special club for cavalier King Charles spaniel created a breeding program against CVD in CKCS. In this program dogs are not allowed to breed until 4 years of age and have to have a heart auscultation without murmurs.

Avel för hållbarhet och livslängd hos köttdjur

The purpose of this literature study was to investigate the possibilities to improve longevity and stayability of beef cattle with breeding. The breeding goal for beef breeds is to produce animals with high capacity for growth and good feed efficiency. Longevity and sustainability are two important features to include in the breeding goal. If longevity is increased each cow can produce more calves and the number of female calves used for recruitment can be reduced and only the best heifers need to be selected for breeding. The benefits of longer life is that it lowers the costs of recruitment animals, it increases the number of young animals that become available for slaughter, and it increases the proportion of high producing animals in the herds.
