Hur en övergång till ett automatiskt mjölkningssystem påverkar juverhälsan :
Automatic milking systems (AMS) have been in commercial use since 1992 and have since 1998 increased a lot. The objective of this study has been to examine the development of udder health on farms converting to AMS. The study also included a comparison of how udder health developed depending on how farms handled cows with mastitis. This was because farms choose to either milk cows with mastitis in a separate barn or in the milking robot.
Other studies on udder health on commercial farms have shown that somatic cell count increases both among individual cows and in the bulk milk when converting to an AMS. No differences between before and after converting to AMS in the proportion of cows treated for mastitis can be found in the literature.
Tidsåtgång i system med självgående/självlastande fullfoderblandare :
In this study I have compared two systems of handling TMR, self-propelled/ self loading mixers and conventional towed mixers, what has been investigated is the time for filling, mixing and feeding TMR as well as maintenance and fuel consumption. The background of this study is the structural rationalization within the Swedish milk production that has put focus on efficiency and reducing of costs. Forage and labour are the two biggest costs in milk production today.
The study has been performed by visiting three farms and with a stopwatch measured the times for filling, mixing and feeding TMR. At the time for the visits, the users have been interviewed regarding maintenance and fuel consumption. They have also had an opportunity to give comments of how they experience the mixers.
The result of the study after processing is that the average stock in the study can save 74000 SEK a year by reducing time for filling, mixing and feeding TMR to cows with a self propelled/ self loading mixer .
The conclusion I can make of this study is that it?s not the size of the stock that decides whether it?s interesting to invest in a self propelled/ self loading mixer, but the presumptions on the farms, for instance forage logistics and mechanical equipment..
Fodersammansättningens betydelse för tillväxt hos häst :
The aim of the present study was to investigate the effect on growth of foals on two different diets, either a forage-based diet or a diet containing approx. 40 % concentrate. The report also includes a review of the pertinent literature on the effects of diet on mares? milk and growth of horses. The hypothesis of the study was that a forage based diet will result in a similar growth pattern as a diet including more concentrates if the diets contain the same amount of energy, crude protein, lysine, calcium and phosphorous.
Effekter av högt kaliumintag på magnesiumbalansen hos mjölkkor :
Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms.
The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.
Jordbruk och mjölkproduktion med kor i Etiopien :
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.
Bystämman som en mötesplats för jordägarna : En lokalhistorisk undersökning om de gemensamma resurserna inom Benestad byalag åren 1886-1928
This study examines the organization of the village society in Benestad, in southern Sweden, during the period from 1886 to 1928. The study focuses on the commonly owned resources in the village and how the landowners there came together and shared the resources. By studying the records of the societies? meetings, and in particular the cases that concerns the common resources, a categorization has been done. The results of the study show that the landowners in Benestad shared pasture lands, milk carriage and other resources with one another. Overall, the village society had a strong organization with at least two yearly meetings about the commonly owned resources.
Storage stability in a milk based UHT-beverage : effect of pH, carrageenan and storage time
The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common
defect in these type of products.
Kreditgivning till lantbruksföretag : en jämförelse mellan Sverige och Danmark
In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease.
This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.
Day to day variation in milk composition at udder quarter level
Syftet med försöket har varit att utröna hur den naturliga variationen ser ut från dag till dag imjölk från separata juverdelar och hur sammansättningen i mjölken skiljer sig inom kor medolika juverhälsa. I den här studien användes 10 kor från Sveriges Lantbruks Universitet sommjölkades kontinuerligt, 2 gånger per dag i 21 dagar på juverfjärdedelsnivå. Mjölken vägdesvid varje mjölkning och analyserades sedan på antal somatiska celler (SCC), laktos, fett,protein, kasein och vassle protein. Resultaten visar att det är signifikanta skillnader imjölksammansättning mellan juverfjärdedel inom ko. För variation är mjölkmängd denparameter som varierar mest och varierar väldigt mycket mellan juverfjärdedelar.
Klostridier och jästsvamp i ensilage ? orsak, verkan och samverkan
Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.
Uppfattning om information avseende kost och fysisk aktivitet vid adjuvant behandling mot bröstcancer
Aim: To describe perceptions about written and verbal information regarding diet and physical activity in women with breast cancer and to study possible differences between ages and perception. Method: A cross-sectional study was conducted and consisted of 57 women with breast cancer stages I-III who started adjuvant chemotherapy within a year (2007-2008). A questionnaire, regarding their perceptions about the written and verbal information they had received about diet and physical activity, was responded to three months following treatment completion. Between 67-93 % of the participants responded to the questions. The answers was analyzed with descriptive statistics and Mann Whitney U-test.
The importance of shade for dairy cattle in Sweden.
Today, there are no regulations saying that cows must have access to some kind of shelter at pasture during the summer. In more tropical countries, it is well-known that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved knowledge.The purpose of this study was to investigate the importance of shade for dairy cows in Sweden. The behaviour of 30 cows was examined to see any differences between cows with access to shade and cows without access to shade.
Hur påverkas kolesterolvärden hos postmenopausala kvinnor med hyperkolesterolemi vid intag av isoflavonoider?
Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical Nutrition3AbstractTitle: How does isoflavones in combination with soy protein impact cholesterol levels in hypercholesterolemic postmenopausal women relative to milk protein?Author: Emma Edberg och Emma NilssonSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician stydy programme,180/240 hpType of paper: Examination paper, 15 hpDate: 2014-05-26Background: Hypercholesterolemia is a major risk factor for cardiovascular disease and the number one cause of death among women in Western countries. Declining levels of estrogen at menopause could be a contribution factor. Isoflavones is a vegetable substance, with structural and functional similarities to the human estrogen. This is a potential reason for possible cholesterol-lowering effects.
Free cow traffic in automatic milking systems (AMS) : a case study on nine commercial dairy farms in Sweden
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.
Kvinnors upplevelser av att leva med bröstcancer
SAMMANFATTNINGSyfte: Syftet med denna studie var att på ett sjukhus i Mellansverige undersöka hur tillfredställda patienterna var med information om läkemedelsbiverkningar Syftet var även att undersöka grad av oro över eventuella biverkningar och jämföra om det fanns någon könskillnad gällande detta.Metod: Studiens design var en kvantitativ tvärsnittsstudie med deskriptiv och jämförande statistik. Data samlades in genom en Studiespecifik enkät. Antalet svarande var 29 inneliggande patienter under 10 veckor som uppfyllde inklusionskriterierna.Resultat: Resultatet visade att hälften av deltagarna inte hade fått information om läkemedelsbiverkningar och att 78 % uppgav sig vilja ha mer information. Nio av tio deltagare instämde till att vara oroliga över eventuella biverkningar och 64 % uppgav att de var osäkra eller inte visste vart de skulle vända sig vid frågor om biverkningar. Trots detta var drygt hälften av deltagarna delvis eller helt nöjda med den information de fått.
