In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.

ABSTRACT. Mastitis is one of the most common diseases affecting dairy cows worldwide. In Sweden annu-ally about 60% of the dairy cows get infected and Staphylococcus aureus cause approximately 30% of these infections. Mastitis causes enormous economic losses. In Sweden, the costs to cure mastitis are estimated to be 192 million SEK per year, excluding the costs for mastitis prevention.

Det finns en utbredd rädsla för skott och andra höga ljud, däribland fyrverkerier, hos våra hundar och många behandlar sina djur med receptbelagda läkemedel för att underlätta den stressfyllda situationen. Vid sidan av dessa läkemedel, med kända biverkningar, finns preparat som säljs receptfritt i handeln. Zylkene® är en produkt som utvecklats av företaget MSD Animal Health och innehåller trypsinhydrolyserat bovint ?s1-kasein. Utvecklaren rekommenderar användning av Zylkene® vid situationer som upplevs som stress- och ångestfyllda för hundar och katter, däribland fyrverkerier.

Fetma hos hund är ett ökande problem med flera allvarliga hälsoaspekter. Det finns ett flertal sätt att mäta andelen kroppsfett, men ingen metod som inte kan kritiseras på en eller flera punkter. De metoder som tas upp i denna studie är exempelvis morfometriska tekniker, ultraljud och absorptiometriska metoder. Predisponerande faktorer till fetma, bland annat överkonsumtion av energi, brist på fysisk stimulans, ålder, kastration och interaktion mellan djur och ägare diskuteras också. Slutligen ges förslag på möjligheter att behandla fetma hos hund med en praktisk handledning till veterinärer och djurkliniker. Syftet med denna studie var att kartlägga svenska hundars hull samt studera deras utfodrings- och motionsvanor i form av en enkätstudie.

Most of the beef production in Sweden has been integrated with milk production. Since the 1990:s, the number of dairy cows has decreased. A specialised beef production has developed in purpose to compensate for this decrease. The consumption of beef have increased in the last decade, but the Swedish production has no followed this trend. In 2004, the percentage of beef self-sufficiency in Sweden was 60 %.

ABSTRACT For hundreds of years there has been a tradition with tethered dairy cows in Sweden. The last decades the old fashioned way to hold cows have been questioned and the number of dairy cows in loose housing has been increasing. Last year (2004) 19 percent in total of all farms with milk production in Sweden had their cows in loose housing. Because of EU-legislation concerning all organic production no farms are allowed to build tie stalls any more and after 2010 all organic dairy cows are supposed to live in loose-housing systems. The aim of the thesis was mainly to find out the number of farms with tethered organic dairy cows and if they will continue after the year 2010. Furthermore the purpose was to study if there are any regional differences, how countries similar to Sweden interpret the EU-decision about tethered cows and differences in buildings between organic and conventional farms and the reasons to them.

SUMMARYFor thousands of years horses have been at people's side. They have been used for transportation at war, to save time, manpower and money. For practical reason, man has forced the horses into narrow spaces. Stabling includes factors as feeding and bedding. In the boxes the bedding materials must be kept clean and maintain good hygiene.
