?Processutveckling av metod f?r tillverkning av en funktionell tibetansk mejeriprodukt?
Probiotics is a special group of health products on the market. The most common type of these is live cultures of lactic acid fermenting bacteria from raw milk . These include, among others, yogurt and various trademarks such as Hälsofil ®, Acidophilus ®, Dofilus ® and Kefir ®. Such products are often used by patients who are treated with antibiotics to combat the intestinal flora eliminated, thus causing digestive problems. The present work deals with yet another type of health product, viz.
Mjölkkyl till espressomaskin : Impressive cooler
The project was made in cooperation with Coffee Queen AB, Arvika. The task was to develop and design a new cooler for the milk to Jura Impressa X9, an espresso machine. The good assistance with staff at Coffee Queen and engineers in China and at KPA in Karlstad led to a solution to the problem. It was a long road to get there, many different concepts was developed. When the day came to decide which concept to work with, the choice stood between two different technical solutions.
Ombyggnation av ett stall för bundna mjölkkor till boxsystem för rekryteringskvigor
To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..
Effekten av sulforafan på genuttrycket av breast cancer resistance protein i MCF-7 celler
Sulforafan är en isothiocyanat-förening som finns i stora mängder i olika kålväxter. Sulforafan har setts ha en kemopreventiv inverkan bland annat genom att inducera fas II-enzymer styrda av transkriptionsfaktorn nuclear factor E2-related factor-2 (Nrf2). Nrf2 är mycket viktig i cellers skydd mor oxidativ- och elektrofil stress och inducerar uttrycket av många olika gener, bland annat olika tranportproteiner. Breast cancer resistance protein (BCRP) är en av transportörerna som tros induceras av Nrf2. BCRP finns i stora mängder i lakterande juvervävnad men också i många andra vävnader där den transporterar läkemedel ut ur cellerna.
Genetisk modifikation möjliggör resistens mot mastit orsakad av Staphylococcus Aureus
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.
Introduktion av förstakalvare i AMS : en enkätstudie
Habituation to an automatic milking system (AMS) for cows in their first lactation differs from habituation to other milking systems. In AMS the cows are supposed to visit the milking station (MS) voluntarily. The milking takes place individually during the whole day, except when the milking system is cleaned. Milking is carried out without any human survey.
The aim of the study was to describe the cow?s introduction in AMS in their first lactation.
Q-feber ? en yrkesrisk för veterinärer?
Q-feber är en endemisk zoonossjukdom som förekommer i hela världen med undantag av Nya Zeeland. Sjukdomen orsakas av den gramnegativa intracellulära bakterien Coxiella burnetii som är mycket motståndskraftig i miljön och kan spridas i aerosoler via vind och damm. Flera olika djurslag kan drabbas av Q-feber men nötkreatur, får och getter samt husdjur som hund och katt är de främsta källorna till humana infektioner. C. burnetii kan hos djur ge upphov till reproduktionsstörningar som t.ex.
Kons fertilitet : kostnader och åtgärder
To get a good economy on the dairy farms the fertility control of heifers and cows is a crucial
factor. It is also important to know which key parameters that should be tracked.
In this work well established routines for heat detection have to be applied. When the dairy
farmers use technical aid in estrus control it is important not to forget that technical aids can
not replace the human eye. Approximately 50 % of all opportunities to inseminate are missed
because clear signs of estrus have not been displayed and/or recorded.
The cattle fertility has been declining over recent years. During the same time the cow?s
proceeds have increased, consequently applying a higher pressure on the cow and the
manager.
Effekter av investeringsstödet i miljö- och landsbygdsprogrammet för perioden 2000-2006 : en studie på företagsnivå
Investment aid is a part of the Rural Area Programme, which contains support to Swedish agriculture and the countryside. There is a new programme every seventh year and SLU (Swedish University of Agriculture) has the mission to perform the evaluation of the previous programme, which lasted between 2000 -2006. The investment aid's aim is to support investments that, among other things, support the adaptation or conversion to more environmentally friendly production methods, improves the product quality, develops new or complementing activities, and improves the environment and the animal- and working environment. The question is if it's only money that matters for these kinds of investments to be done and what has happened with the money that was paid? This thesis investigates how the investment aid has affected the receivers.
Nu a?r det dags att agera! : en analys av konsumentbeteende fra?n mjo?lkupproret i Ska?ne
At the end of 2008, Arla concluded agreements with several supermarkets in southern Sweden. The agreement with the supermarkets excluded Ska?nemejerier from the stores. This meant that Ska?nemejerier lost approximately 7% of sales volume.
Ambitionen om det essentiella : Innebörder av urmjölkning utifrån levda erfarenheter för mammor vars barn fötts prematurt
Bakgrund Många mammor som fött barn prematurt önskar amning som uppfödning för sitt barn för bröstmjölkens immunologiska faktorer och som en kompensation för att graviditeten avslutats för tidigt. Amningens etablering kan vara komplicerad och kräva tålamod när barnet behöver vård. Beroende på barnets känslighet kan det ta olika lång tid tills barnet kan påbörja amningsträning. En av de viktigaste faktorerna för att amningen ska kunna etableras är att mamman får igång en tillräcklig mjölkproduktion motsvarande den mängd ett fullgånget barn skulle kräva. För att få igång en tillräcklig produktion är det bra att komma igång med urmjölkning så fort som möjligt efter barnets födelse.
Hackelselängdens betydelse för tuggtid och foderkonsumtion hos mjölkkor :
Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis.
Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.
Äppelpressmassa i Sydsverige - nuvarande användningsområden och möjligheter till nya produkter
Pomace is the solid remains (i.e. stems, pulp, seeds, and skins) after pressing for juice. The annual production of apple pomace is 593 000 ton worldwide. Its field of application depends on local conditions. In order to investigate the field of application of apple pomace in the Southern Sweden, six persons on companies with production of apple juice were interviewed.
Mjölkkors välbefinnande i AMS och konventionell lösdrift : skillnader i beteende och hormonstatus för oxytosin och kortisol mellan kor av hög och låg social rang
The purpose with this study was to investigate how the behaviour and physiological parameters differ between high ranked and low ranked cows, and between cows in an automatic milking system verses conventional milking parlour. The study was carried out at the Kungsängen research Centre, Department of animal nutrition an management, Swedish University of Agriculture Sciences, Uppsala. Twelve cows, the six highest and the six lowest in social rank were selected from the automatic milking system for the experiment. Ten cows, the five highest and five lowest in social rank were selected from the conventional system. Blood samples were taken during milking and resting.
EU ger eko bland korna - från uppbundet till lösdrift :
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.
