Working horses in developing countries are mostly used for transportation. They are often owned by people with limited economical resources and lack of knowledge about how to take care of the horses and due to this the horses often suffer from problems such as dehydration, poor body condition, lesions and parasitic infections. The aim of this master thesis was to investigate if free veterinary care improved the health and hydration status of working horses in Nicaragua and it was performed as a part of a project called ?Free veterinary assistance for working horses and training of their owners as veterinary promoters in the Pacific coast of Nicaragua?. Five parameters were used to investigate whether free care improved the health of working horses in six towns along the Pacific Coast of Nicaragua.

Haemonchus contortus is the most important bloodsucking gastrointestinal nematode in small ruminants worldwide. It is often controlled by anthelmintics. Even though other methods to control are available, the most efficient way to treat an animal with clinically manifested haemonchosis is to use one of the available broad spectrum anthelmintics: benzimidazoles (BZ), macrocyclic lactones (ML) or imidothiazoles-tetrahydropyromidines or the narrow spectrum drugs salisylanilides or nitrophenols. Anthelmintic resistance (AR) against all groups of anthelmintics in nematode Parasites has been reported from many countries, and even multiple AR has been observed. In this study I have investigated the resistance levels to all major classes of broad spectrum anthelmintics in a naturally infected flock of sheep of Red Maasai sheep (RM), Dorper sheep (D) and their offsprings on a research farm in Kenya.

Cryptosporidium parvum is a protozoan Parasite causing diarrhoea in many different animal species including cattle and man. It is an important enteric pathogen in neonatal calves and it is the second most common pathogen found in diarrhoeic calves in Sweden. Subclinically infected adult cattle have, in international studies, been shown to shed a low number of oocysts in faeces and this has been recognised as a potential source of infection for new-born calves. The detection methods used for diagnostic purposes are based on microscopic investigation of faecal smears. These methods have a fairly low sensitivity and samples from subclinically infected cattle have to be concentrated before analysis.

I have studied the suburban municipality of Botkyrka, south of Stockholm, from a rural perspective. Through that I`ve compared how countryside comes into being with the planning and building of suburbs. I have looked for a definition of Countryside, and found that it is often explained or defined in negative terms, as what it is not. In that it says nothing about what it really is, or about the qualitiies it has to it. Botkyrka is a suburb, but it does in large parts consist of countryside. Apart from defining countryside and rural I´ve been searching for a definition of suburbia, of it´s structure and the mental picture we have of it as a cultural phenomena. In order to understand the role that suburbs have in planning I describe their history from Italian renaissance villas to sprawl. By opposing urban and rural, modern urban planning and how rural areas are created, I´ve come to a definition of rural planning and the making of countryside. To make countryside, planning and building should come from individual needs and desires. A relationship to the surroundings based on continous interaction between the human beeing and it´s environment, a constant process of shaping and reshaping. To put my thoughts to the ground I have collected examples of projects and ideas, that fits into my view of what rural planning and making countryside is all about. They are put in different categories according to the possibilities of influence and to what degree it is put into private hands. The first category is ?allemansrätten?, every mans right. That is the rigt to use private land as long as you don´t disturb or destroy.

Infection with Parascaris equorum is common among young horses in Sweden as well as in the rest of the world. The Parasite has a direct lifecycle and reproduces in the small intestine. The eggs are passed out with faeces and become infective after approximately two weeks. The horses get infected when they ingest eggs that are dispersed in the environment. The symptoms seen in horses usually include retarded growth and loss of weight.

Organic rearing of broilers is not a large production in Sweden. In order to create a sustainable yet efficient production of organically produced poultry meat, at a price that the consumers are willing to pay, much more knowledge is needed. It is therefore important to do more research on organic broilers under Swedish conditions. This report is aimed to be a base for further studies. In the study 2000 broilers of the hybrid Ross 308 divided in to two equal groups. The broiler hybrids that are used in Sweden are selected for a high growth rate and are normally slaughtered at the age of 5 to 6 weeks, with a slaughter weight of 1.7-2 kg.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and Parasite. These have different characteristics which mean that they require different water treatment to be separated.

Renen har genom tiderna varit ett bytesdjur, arbetsdjur och produktionsdjur. Dagens renskötsel är inriktad på köttproduktion med sekundära inkomster från pälsar och hantverk. Rennäringen drabbas årligen av ekonomiska förluster till följd av snöskred, laviner, trafikolyckor och rovdjur. Även förluster i form av minskad reproduktion och minskad slaktvikt uppstår till följd av exempelvis virus, bakterier och Parasiter. Att Parasiter orsakar förluster för djurproduktion är ett välkänt problem världen över.
