Levande vikt vid olika åldrar och sambandet med bröstomfång och mankhöjd hos SRB och SLB :

Live-weight at different ages for Swedish Holsteins (SLB) and for the Swedish Red and White Breed (SRB), and the correlation to heart girth and height at withers. The aim of this investigation was to study the live-weight changes and mature weight for the Swedish Red and White Breed (SRB) and for Swedish Holsteins (SLB), and to estimate the correlations between body weight and body measurements such as heart girth and height at withers, respectively. The material used was from one of the experimental dairy herds (Jälla) of the Swedish University of Agricultural Science. It included recordings on 293 dairy cows with information from 7142 weight occasions and recordings on 275 dairy cows with information of 557 heart girth measurements and 560 measurements of height at withers. The registrations were done during 1993-2002. There was a large variation in live weight between cows in different ages and lactation stages.

Effekt av biotintillförsel på klövhälsan hos mjölkkor i lösdrift : ett kontrollerat fältförsök på tre gårdar

The Effects of dietary biotin supplementation on hoof health in Swedish dairy cows - a controlled cohort field study. The aim of the present degree project was to investigate the effects of biotin supplementation on hoof health in dairy cows. The experiment was performed as a controlled cohort study in three commercial farms in western Sweden from January 2002 to October 2002. The cows were all housed in cubicle systems with transponder concentrate feeding systems. Within each farm the cows were allocated to either biotin or control treatment. The biotin groups received 20 mg of biotin per cow and day, starting 14 days before expected calving.

Swedish dairy farmers? interest in using price risk management tools : a study of correlating factors

The dairy market will change importantly in the coming years. The quota system, which has regulated the European dairy production, will disappear in 2015 and the European dairy market will then be importantly affected by the volatility characterizing the dynamic of world prices. Besides this, the global demand of dairy products is expected to increase due to the growing world population. Farmers in countries such as the U.S. and New Zealand, when compared to Swedish farmers, show greater familiarity and experience with risk management tools.

Teknik för egen foderberedning :

There is an uncertainty in the market for grain forcing the meat/milk producers to review alternative feeds to a larger extent, in order to get control over the feed costs. This has led to that the meat/milk producers need to have a good knowledge regarding how the different feeds influences the animals and which technical equipment to use for handling. For those that produce their own feedmix, there is a need to put interest in new crops and their characteristics to be able to get the knowledge of what is required for their own production. It is beneficial to keep an open dialogue with advisors to be updated in new crops and new technology for feeding. When mixing feed at farm level, the legislation is not very clear since it the target group is large scale mixing plants. We have brought up the most important rules and regulations from the EU parliament Council as well as the ones from the Swedish Board of Agriculture (SJV), regarding feed mixing on farm and factory level. We have studied beans and pea at two different moisture levels, in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill.

Development of new food products with components active against Helicobacter pylori - with purpose to improve gastric health in humans

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

Fertility before and after installation of Herd Navigator?

The fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.

Deltidsbete : effekt på mjölkkornas foderintag och avkastning

Detta arbete är en litteraturstudie som handlar om hur deltidsbete påverkar mjölkkors avkastning, foderintag och välfärd. I Sverige har vi beteskrav till skillnad från många andra länder i världen. Detta skapar problem då besättningstorlekarna ökar och det blir svårare att få marker i närheten av gården att räcka till alla kor. Det största problemet med mjölkkor på bete är dock att högavkastande kor inte producerar lika mycket på bete som inne på stall. Det är därför viktigt att finna ett sätt att lösa problemen som både gynnar kon och bonden.

Calcium homeostasis at calving in cows milked prepartum

Dagens hästägare utfodrar inte sina hästar med enbart grovfoder. Många av dem fodrar stora mängder kraftfoder och en del hoppas att det kommer förbättra hästens prestation. Spannmål har ofta ett förhållandevis högt energiinnehåll och lämpar sig därför i foderstater till hästar som har ett högt energibehov. Utfodring av stora mängder energi kan orsaka problem för hästen, bland annat i form av kolik och många stereotypier som vävning, krubbitning och boxvandring. Eftersom det finns hälsorisker med foderstater med mycket kraftfoder i, är det av intresse att undersöka hur olika kraftfoder påverkar hästens hälsa, ämnesomsättning och prestation men även om det går att ersätta kraftfoder med ett energirikt vallfoder.

Magnesiumstatus hos mjölkkor : en fältstudie

Magnesium is an essential mineral that is important for several physiologic and biochemical processes in the body. Deficiency of magnesium is mainly associated with grass tetany, but can also appear in cows during the indoor period. Since long it is known that potassium has a negative effect on the absorption of magnesium. Due to the fact that potassium fertilisation leads to a higher potassium content in forage, it is of interest to study interactions of potassium on the magnesium balance in dairy cows. There are few studies about magnesium feeding to dairy cows in Sweden and the purpose of this study was to investigate how much magnesium and from which feed-sources dairy cows in Sweden get their magnesium. Data was collected from seven farms in the northern part of Uppland and from seven farms in Skaraborg in Sweden.

Outsiders i Gus Van Sants filmer : En tematisk auteurstudie

In this paper I have examined how the structure of society affects the characters in the movies of Gus Van Sant, and what there is that characterizes Van Sant as an auteur. I have also looked at the thematics and how the characters develop throughout from his first movie Mala Noche (US 1985) until one of his latest Milk (US 2008). Van Sant is open with his Homosexuality and those perspectives are of major importance for this study. He presents how his characters try to live a normal life in a society that is not made for them. I have chosen to analyze five different movies.

Breastfeeding and caries. Is there a connection between breastfeeding longer than one year and caries before the age of six years?

Studien syftet är att undersöka om barn som har ammats längre än ett år har ökad risk för karies före sex års ålder. Metoden är en systematisk litteraturstudie där databaserna Cinahl, Cocharane och PubMed har sökts. Resultatet baserades på fyra kohortstudier och tio tvärsnittsstudier. Resultatet av dessa fjorton studier kan indelas i två riktningar, studier som visar att amning längre än ett år ökar kariesrisken och studier som indikerar att amning inte ökar risken för karies. Slutsatser: Utifrån resultatet av artiklarna får det anses att det vetenskapliga underlaget är otillräckligt för att hävda att amning ökar risken för kariesutveckling..

The effect of hoof trimming on dairy cows´ behaviour, locomotion and production

The Swedish dairy production today consists of big farms and different housing systems are in use. These systems put demands on the cows? ability to cope with the environment and one challenge is the claw health in the herds. Some claw lesions that are frequently observed are foot rot, hemorrhages, digital dermatitis and sole ulcers, which can be caused by, for example, the claws? environment and the flooring type used.
