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.

En stor del av jordbrukets växthusgasutsläpp kommer från nötköttssektorn. Dess produktion påverkas i Sverige och EU av EU:s jordbrukspolitik. En större del av jordbrukssubventionerna var tidigare kopplade till produtionen vilket gav incitament att öka produktionen. 2003 infördes en reform med gårdsstöd som var frikopplat från produktionen. I uppsatsen studeras litteraturen kring hur nötköttsproduktionen påverkas av gårdsstödet, och utifrån detta görs egna beräkningar om förändringar i växthusgasutsläpp.

Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.

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.

Electrical stunning is the method that has been used in Sweden to stun broilers prior to slaughter. However, for reasons of animal welfare and Meat quality, research has been made in the EU to develop new stunning methods. Gas stunning is now regarded as the best alternative. In this study literature has been reviewed with focus on different gas stunning systems and observations have been made at two different slaughterhouses regarding animal welfare before, during and directly after stunning. At one slaughter plant carbondioxide was used in a two-stage system where the birds were standing on a conveyer belt during the stunning procedure.

Uppsatsens syfte är att undersöka aktuella mediedebatter om köttkonsumtion ur ett djuretiskt perspektiv. Studien bygger på teorin om karnism och kritisk diskursanalys. Artikelsökningen gjordes genom Mediearkivet Retriever och avgränsades till de fyra största tidningarna i Sverige, Aftonbladet, Dagens Nyheter, Expressen och Svenska Dagbladet, från 2014 fram till idag. Det empiriska materialet bestod av 25 artiklar och ur dessa framkom fem diskurser: köttnormsdiskursen, djurrättsdiskursen, hälsodiskursen, marknadsdiskursen och miljödiskursen. Diskurserna gick ofta in i varandra och hade ofta fler än ett perspektiv.

Hepatitis E virus, HEV, is a frequent causative agent behind, especially waterborne, infections in developing countries such as India. However, during the last years the number of non-travel-associated infections in industrialised countries, for example US, Germany and Sweden, has increased. The symptoms vary from mild with nausea to icterus and it can even be lethal. There are four different genotypes of HEV and many studies consider HEV infection to be a zoonosis. Scientists have by using phylogenetic analyses found great genetic similarity between strains isolated from humans, pigs and food, such as pork and liver, especially among viruses belonging to genotype 3.

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.

In the beginning of the 1990?s ratite breeding for Meat production was introduced in many European countries, including Sweden. The knowledge of ostrich farming and diseases of ratites is increasing internationally but is still often limited among veterinarians. This report consists of a literature study and a summary of pathology findings from ratites submitted for necropsy to the National Veterinary Institute (SVA) in Uppsala, during 1995 to 2001. The purpose is to give a general introduction to ostrich and ratite breeding and to give an overview of the most common diseases. The necropsy data from 1995 to 2001, indicate that many of the diseases are management related rather than caused by infectious agents. Due to cold climate ostrich breeders in Sweden need to supply well designed buildings and good care of the animal.

The Sheep is the oldest livestock, and has been in Sweden for 4-5000 years. Thanks to that you can obtain skin, as well wool and Meat. Therefore it was an important animal. Sheep production has increased, strongly lately due to the pasture support. The purpose of this paper is to find out what kind of different EU-subsidies you can get and to compare the subsidies in Öland and the main land. Sheeps are very good conservationist with grass, bushes and herbs, because of different grazing lands hardness and growth is it important to control the pasturage strain. A good way to regulate this is to have different enclosed pasture to switch between. I have been studying the different EU-subsidies.

The demand för Swedish pork Meat is increasing every day. This leads to agricultural farming having to develop as an industry, with larger and more rationalised units to make the farming more effective and to raise the financial profit. The consequence of this is that it affects the animals when their surroundings become more industrial. The pig´s natural behaviour becomes restricted by the limitations of the facilities, which leads to them becoming understimulated. Helena Kummel, a teacher at Munkagård upper secondary school and also an educated animal inspector has developed a prototype that could possibly replace the pig´s natural rooting behaviour inside the barn. The porpuse of this report is to study "bökboxen" in the gilts´actual living enviroment, through qualitative- and quantitative analysis.

This degree project aims to evaluate alternative methods to the unanaesthetized castration of piglets. Castration of piglets is performed to prevent the development of boar taint. Boar taint can cause great financial losses for the pig manufacturer. Unanaesthetized castration of piglets is not regarded to be satisfactory from an animal welfare perspective and the procedure will for that reason be outlawed in the near future.Several alternative methods are used in countries all over the world with promising result. The purpose of this study is to evaluate if this methods could be applied in Swedish pig production.A literature study has been combined with interviews; field studies, questionnaires and a small study on male pig production.To be applicable to and applied in Swedish pig production the alternative method must be financially accepted by the manufacturers but also accepted from an animal welfare perspective.Castration is the only way to guarantee a Meat free of boar taint.

Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in Meat.
