Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

The aim of this work is to give an example of how archaeoacoustics can broaden our understanding of archaeological remains and to further contribute to the almost non-existing research of ringing stones. With a theoretical discussion about sound from three different perspectives and by means of using different kinds of analysis, this essay will show that there are unknown relations between the three known ölandic ringing stones and the cultural landscape of Öland. Possible patterns in the placement of the stones and the possibility of the sound in this soundscape will be investigated. The essay will also suggest a resonant stone typology and discuss the necessity of one. Finally, the intention is also to shed new light upon the discussion on what the uses of the ringing stones might have been..

Peat litter has been used in animal houses for a long time. Because of its good ability to absorb liquid and nutrients from the manure it can create a dry surface for animals and a valuable manure product. Through changes in agricultural practises the use of peat litter has diminished and is to a great extent replaced by straw, sawdust and cutter shavings although Sweden is rich in peat-findings. The aim of this work was to summarize the presented knowledge about the used of peat litter, techniques, advantages and disadvantages and to compare with other commonly used litter materials. Articles on peat litter have been searched for in magazines, databases and books at SLU library. Visits to peat industries, interviews with peat producers and with peat researchers contributed to the material. Peat is not a uniformly material.

The aim of this study is to understand which roles institutional personnel in HVB-homes (homes for care or living), that include animals ascribe the animals for the young clients in treatment. Using the termsrole, role-taking, primary socialisation and secondary socialisation within the perspective of symbolic interactionism, we intend to analyse the expericences from the institutional personnel of what roles the animals are ascribed in treatment of young clients. We also wanted to find out if the institutional personnel have certain expectations on the animals as tools in the treatment and whether the institutional personnel believes that the animals have important roles in the treatment of the young clients.To find the answers of our aim and approach to our problems, we have used a qualitative study where we have interviewed six institutional personnel distributed in three different HVB-homes that uses animals in treatment of young clients. Our empirical material shows that the institutional personnel ascribe the animals a variety of roles, which among others are: friendly and familiar, meaningful, safe, comforting and soothing. Other roles that the institutional personnel ascribe the animals for the young clients are: teaching in order to develop empathy and responsibility; helping in therapy situation and having an activating role.

This report describes how wavefiles can be recorded with programs written in the C++ language . The report also describes how the recorded sound is handled before it can be analyzed. The report describes the different parts that make a wave file to a wave file and how Windows handle these files. There is always some silence or noise of unknown length that passes through the system before some interesting sound arrives. That silence or nose must not be recorded and therefore some function must be developed that can detect interesting sound or speech.

We have made a litterature study about pain in animals. In this studie we have brought up areas like sign of pains in animals, pain relief and the care perspective. Pain is perceived when body tissue is damaged or nearly damaged by stimuli. Nociceptors, which are receptors placed at nerve endings, responds to a provocation of pain and transmit an impulse along the nerve to the brain via the spinal cord. Pain is urgent or chronic, and can be divided into nociceptive pain (somatic pain and visceral pain) and neuropathic pain. Different pain mechanisms can arise, such as referred pain, which is when signals of pain are referred to other parts of the body.

The United Nations has a responsibility to combat acts of international terrorism, as they constitute a threat to international peace and security. In spite of this, there exists no generally accepted definition of the phenomenom within the UN. By examining resolutions on terrorism, this thesis aims to evaluate the UN?s policy on terrorism since the end of the cold war until 2003. The results show that the UN?s attitude towards terrorism eversince the end of the cold war has been condemning, but that the the events of September 11th 2001 has contributed to an even more firm approach to the problem.

Background: Infection with Human Papillomavirus, HPV, is one of the world's most common sexual transmitted infections. The virus causes genital warts (condyloma) but certain virus types can cause cancer. The most common cancer type caused by the virus is cancer of the cervix. Nowadays there is a screening program for women between 23 and 60 years of age where Pap smears of the cervix is taken to discover abnormalities at an early stage. Cervical cancer is very common all over the world and this screening program saves many lives, but not in the less developed countries since the screening program is too expensive.

To differentiate between bones from sheep (Ovis aries) and bones from of goats (Capra hircus) is a long lasting challenge for zoologists, archaeozoologists and osteologists. Especially considering archaeological remains which are often found fractured and poorly preserved due to taphonomic processes. Zeder & Pilaar?s (2010) and Zeder & Lapham?s (2010) methods of species differentiation has shown promising results when used on bones from modern sheeps and goats. This paper aims to evaluate these methods by exerting them on excavated bones from kv.

This project was initiated by a veterinarian, that at stallion performance tests for breeding during a number of years, noted breed differences in various types of testicular disorders. Therefore it was of interests to examine the proportion of testicular disorders within certain breeds. The aim with the project was in a first part to study cryptorchidism in common horse breeds in Sweden. Information about castrations of stallions performed during a 10 year period (2000-2009) was collected from computerized case records at five animal hospitals. The case records showed the numbers of castrations, normal cases and cases preformed on stallions with cryptorchidism, abdominal respectively inguinal.

In the debate on laying hen welfare, and specifically housing conditions, the main focushas been on physiological and behavioural measures. What is lacking is knowledge of howthe hen experiences the situation ? her state of mind.This study is an attempt to gain insight into the private mental states of former batteryhens. It uses a cognitive bias method based on spatial judgement, i.e. judgement of aambiguous stimulus placed spatially in between a reinforced and an unreinforced stimulus.This method has previously shown differences in judgement by animals in enriched versuspoor housing.

Den ekologiska produktionen styrs av många olika lagar och regler som den konventionella produktionen inte behöver följa. Dessa regler kan ses som en välfärdsgaranti i den ekologiska slaktkycklingproduktionen då reglerna främst är skrivna för att kycklingarna ska kunna utföra sina naturliga beteenden i en passande miljö. Rastgårdar ska finnas till de ekologiska kycklingarna för att de ska få beta, få motion och få chansen att bygga upp sitt naturliga immunförsvar. I många fall ses rastgården som en positiv aspekt av den ekologiska produktionen, men det finns även problem relaterade till utevistelsen då exempelvis vilda djur kan lockas till slaktkycklingarna och på så vis stressa upp dem, smitta dem med parasiter och patogener eller äta upp dem. Det är vedertaget att den ekologiska produktionens dödlighet är högre än den konventionella produktionens på grund av rovdjuren och sjukdomarna och de ekologiska kycklingarna utsätts i många fall för fler smittorisker på grund av utevistelsen.

Jönköping Small Animal Hospital is today the only clinic in Sweden to offer radiation therapy as a treatment of tumours. The body contains of billions of cells that all have to obey the regulations that are established. If a cell is exposed to a harmful substance, for example a chemical, it can be transformed into a tumourcell. Normally the body has a good defence but the tumourcell can survive and start to divide unrestrained. A tumour is starting to develop.

Mulesing is a surgical husbandry procedure performed on lambs in Australia. The reason is toprevent severe fly-strike to the breech area, which otherwise risks to be soiled with faeces.This problem is mainly occurring in sheep of the Merino breed. Their fine wool is in demandworldwide due to high quality. Mulesing has been performed since the 1930?s, and eventhough alternative methods have been discussed nothing is yet generally accepted.
