Uppbyggnaden av ett foderstatsprogram för dikor :
The object with this work was to create a simple feeding program for beef cows. Another object was that I could learn more about the properties and functions of Excel and Visual Basic.
I used parts of a program I designed a few years ago. This old program was neither user friendly nor had it an appealing layout.
Initially I decided how I wanted the new program to appear and on which foundation it should be built. I designed various forms into a spread sheet, such as lists and multiple choice buttons. Using VBA (Visual Basic for Application) I could create macros, which used the information chosen in the lists and with the multiple choices to calculate the feeding requirement or the feeding plan.
Differences of progressive retinal atrophy in dogs
A group of diseases that affect the dog?s sight is progressive retinal atrophy (PRA) a disease that means that the photoreceptors in the retina of the eye either not develop normally or undergo degeneration and thereby causes vision loss and blindness. The disease affects many different breeds and is inherited. What have been shown is that it is different genes that had become mutated in the different breeds, this conclude that despite similar clinical symptoms, the underlying reason could be different. Also the genes that are mutated in dogs and give rise to diseases also exists in humans.
Näthinnesjukdomar hos hund :
An array of different retinal disorders is present as a threat in quite a
number of dog breeds. These often lead to profound visual impairment or
blindness. Many of the disorders are genetic, and they are, in Sweden as
well as in other countries, subject to breeding programmes.
The anatomy of the eye and the retina, as well as current examination
techniques (ophthalmoscopy, electroretinography (ERG) and genetic
analysis) are described. The more common retinal disorders encountered
in dogs in Sweden are discussed: retinal dysplasia, generalized
progressive retinal dystrophy, retinal pigment epithelial dystrophy, collie
eye anomaly, sudden acquired retinal degeneration, retinal detachment
and choroiditis. The possibly affected breeds are listed.
The value of diagnostic findings is discussed and current advances on the
subject in ophthalmologic research are accounted for..
Fortplantning och fortplantningsproblem hos tikar av svensk och finsk lapphund : en jämförande studie
The Swedish Lapphund is one of our eleven Swedish domestic breeds of dogs and one of Sweden?s oldest dogbreeds. The Finnish Lapphund?s origin and physical conformation is similar to that of the Swedish Lapphund.
One aim of this study was to examine whether the average litter size differs between these two closely related breeds, and if so, try to find causes for this.
Omplacering av hundar : situationen i Sverige
I the year of 2008 there were more than 60 000 purebred dogs newly registered in theSwedish Kennel Club. In addition there are a lot of mixed breed dogs and in the year of2006 it was estimated that there were over 700 000 dogs in Sweden. In today?s society it isnot unusual that people change their life situation by moving, getting a new job or startinga family. Because of this there is a risk of rehoming for dogs owned by these people.In Sweden dogs are among others rehomed by advertising or by rehoming organisations.
Förekomst av MyBP-C mutationer hos katter med hypertrofisk kardiomyopati :
Hypertrophic cardiomyopathy (HCM) is the most commonly diagnosed cardiac disease in cats. The phenotype varies from mild focal thickening to severe concentric hypertrophy at the left ventricle. Two separate myosin binding protein C (MYBPC3) mutations have been identified in Maine coon cats (A31P and A74T) and one in Ragdoll cats. All three of them seem to cause familial HCM in an autosomal dominant pattern.
The purpose of this study was to investigate the presence of these three mutations in population cats of different breeds with HCM in Sweden. The results may show if HCM is present in the absence of these mutations.
Hälsokontrollen av den gemensamma jordbrukspolitiken (CAP) : effekter på lantbruket genom gårdsstödet
The Healthcheck is an evaluation of the 2003 years reform of the Common Agricultural Policy (CAP). When the Healthcheck of CAP is decided, most likely in the beginning of 2009, there will be a discussion about how CAP will appear in the next budget period 2013. One main question in the Healthcheck is how the farm support will be designed. A suggestion that has arised is if todays addition amount for dairy- and beef production should be transferred to the fundamental farm support. In this exam theses calculations has been done in created typical farms in every Swedish support region for cereals-, dairy- and beef production.
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.
Aortic Body Tumors in Dogs
The purpose of this essay was to review the literature and describe the patophysiology, diagnosis, microscopic and macroscopic appearance of aortic body tumors in dogs. The tumors originate from the chemoreceptor organs situated at the base of the heart. The chemoreceptor organs are neuroendocrine cells responsible for surveillance of changes in e.g. the blood pH. Aortic body tumors are rare and represent 7 % of the total cases of primary cardiac tumors in canines.
Omplacering av hundar : ras, kön, boende och orsak
Many dogs in Sweden are put up for adoption at the Swedish buy- and sales site?Blocket?. This because in Sweden, rescue shelters mostly takes in dogs that have been confiscated by the police. The aim of this study was to investigate what kind of dogs that are put up for adoption and why owners put their dog up for adoption and also compare the results with those from other countries. 800 dog advertisements from ?Blocket? were collected in the study between January 31st and April 10th 2012.
Effekt av utfodring och motion för utveckling av diabetes mellitus hos gråhund och jämthund. :
This study is a follow up of a pilot study made 2004, that evaluated feeding, exercise and weight as possible risk factors for developing any kind of diabetes in dogs. We have selected our material for a certain kind of DM that exists among Norwegian and Swedish elkhounds. These breeds are among the most common breeds affected by diabetes and this kind of DM almost exclusively affects intact bitches.
We performed a case- control study where the owners were interviewed over the phone. The owners of a total of 48 case dogs and 58 control dogs were contacted. The questions for the cases focused on the time before the diagnosis and the questions for the control dogs focused on the dog´s adult life.
Grazing behavior of Ankole and Boran cattle in an improved herding production system
To be able to provide the growing human population with food, the productivity of the animals as well as land use needs to be improved and intensified. Hence, understanding the behavior of animals is crucial both for animal welfare and productivity as well as the management of the cattle. There are many factors affecting the grazing behavior of cattle in tropical conditions, such as human-animal interactions, herd management, breed, season and temperature. The purpose of this study was to investigate the grazing behavior of two tropical cattle breeds, Ankole and Boran cattle. Kenyan Boran belongs to a zebu type of cattle and is preferred to many other breeds due to the higher productive and reproductive capacity and adaptability to tropical conditions.
Prövning av liggtidssensorer som indikator på förestående kalvning hos dikor
The aim of the study was to find repetitive behavioral patterns pre calving that could be used as indications of calving in beef cattle. In the study sixteen Standing- and lying down sensors were attached to the leg of sixteen beef cows. Ten of the sixteen beef cows gave birth to calves during the trial period. From these ten cows, data from six cows were used to assess the sensors fitness for use as calving indicators. The analytical part of the experiment was divided into two parts, calculation of divergence of mean lying time within different time intervals, and the number of lying bouts.The first part consisted of optimization of an equation used to highlight divergence in mean lying time within eight different time intervals (3, 6, 9, 12, 15, 18, 21 and 24 hours).
Klövform och klövsjukdomar hos intensivt uppfödda köttrastjurar :
The top selection of Swedish beef bulls are evaluated yearly by Svensk Köttrasprövning AB at Gismestad. The bulls are selected from six different breeds; Angus, Blonde d´Aquitaine, Charolais, Hereford, Limousin and Simmental, and are kept on straw bedding apart from a concrete alley in front of the feeding area during the six months of evaluation period. The bulls are evaluated according to their fertility scores, growth, exterior and temperament and the exterior, body posture and claw conformation reflect important qualities for their longevity. In spite of good values for fertility, it has been noticed in the last years that the fertility results and longevity have been unsatisfactory and claw and/or bone disorders have been suspected as a contributory cause.
Persson et al. (2007) studied breeding bulls from Gismestad and other places, which had been slaughtered due to poor fertility (no pregnancies in the herd during their last year in service).
Progesteronrelaterad diabetes mellitus hos älghund :
Diabetes mellitus (DM) is a relatively common endocrine disease in dogs and is more common in certain breeds than others, e.g. Nordic spitz breeds. Within the Swedish and Norwegian Elkhound population, female dogs are almost exclusively affected. The hypothesis in this study is that Swedish- and Norwegian Elkhounds develop DM during the progesterone phase of estrous (diestrous or pregnancy).
Medical records from 51 female dogs of the breeds Swedish and Norwegian Elkhound were studied.
