Cross-suckling when sows are group housed during lactation : associations with sow productivity and behaviour
Cross-suckling, i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of knowledge regarding cross-suckling increases. The overall aims with this thesis was to investigate how sow behaviour and productivity are associated with the occurrence of cross-suckling, and to investigate consistency in sow nursing behaviour related to cross-suckling.
The study included information about the first 4 parities of 40 LxY sows kept in outdoor and indoor production environments. Sows were single housed the first 2 weeks after farrowing and group housed (4 or 5 sows per group) from 2 weeks after farrowing until weaning, 7 weeks after farrowing.
Vilken nutritionsbehandling har bäst effekt på tillväxten hos barn födda för tidigt och/eller med låg födelsevikt?
Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: ?What nutrition therapy has the best outcome on growth in preterm children and/or children born with low birth weight??Author: Josefine Nyström and Rebecca HammarSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2013Background: There is a number of reasons why a child is born preterm and with a low birth weight, for instance if the mother is underweight, smoking or exposed for malaria. The negative consequences of being born preterm or with a low birth weigth are many, both on long and short term. According to the WHO preterm birth is the most common direct cause of infant mortality. By providing the right measures in time when it comes to nutrition the mortality can be reduced considerably.Objective: To examine and summarise the scientific ground when it comes to the best nutrition therapy for preterm children and children born with a low birth weight.Search strategy: A systematic literature search was done in the databases Pubmed, Cohrane and Scopus.
Implementation av en COLLADA inläsare för Agency9
Behovet av mängden grafiska detaljer i spel och realtidsapplikationer ökar i och med intåget av nyare och kraftfullare hårdvara. Detta sätter mera press på grafiker. Det finns ett behov av att simplifiera processen med att flytta stora datamängder från olika editorer (Maya, 3dsMAX, Blender, mm), processa denna information och presentera det på skärmen utan att låsa sig fast vid en specifik editor. COLLADA är ett steg mot detta mål. Hur kan COLLADA implementeras i grafikmotorn AgentFX, utvecklad av Agency9? Detta examensarbete presenterar ett tillvägagångssätt genom Java och COLLADA med JAXB att implementera stöd för COLLADA i AgentFX, för att rendera komplexa scener byggda i Maya Unlimited 6.5.
Etiologi och patogenes för benign prostatahyperplasi hos hund
This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.
The genetic background of oxytocin and its importance for maternal behaviour of sows
Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.
Om obstetrik och osteologi. Paleodemografiska perspektiv p? graviditet, f?rlossning och obstetrisk v?rd under svensk medeltid och tidigmodern tid
This essay examines possible maternal deaths in paleodemographic analyses and grave material by comparing three cemeteries: Nya L?d?se, Helgeandsholmen and V?sterhus. By comparing mortality patterns and burial practices, the aim is to investigate possible signs of obstetric care during medieval and early modern Sweden. The results show a higher death rate for adult women in all three burial places, indicating possible maternal deaths. Fetuses and small children were found in all cemeteries and potential evidence of medical knowledge were found in Nya L?d?se.
En inventering av hälsoläget hos amerikansk bison (Bison bison bison) : i svenska besättningar
American bison (Bison bison bison) is a new species in Sweden and was
introduced in the year 2000. In this study the result of an interview and a field
investigation is presented. The aim was to investigate the health and parasite
status in Swedish bison herds. The most common reason to begin with bison
breeding was meat production and/or sale of breeding animals and tourism. The
Swedish breeder?s experience of bison is that they in general are healthy.
Tambins inverkan på naturligt förekommande pollinatörer
Det här arbetet handlar om tambins inverkan på naturligt förekommande pollinatörer. Min frågeställning berör: tillgången på näring, hälsotillståndet och populationsnivån hos naturligt förekommande pollinatörer i förhållande till tambins närvaro. Det som framkommit av den här litteraturstudien är att introducerade tambin leder till att naturligt förekommande pollinatörer minskar i antal kring bikuporna, en del arter söker föda på andra blommor eller senare på dygnet än tidigare. Den minskade tillgången på föda som denna konkurrens innebär har en negativ inverkan på humlors kroppsstorlek och därmed deras överlevnad. Samt att tambin kan föra över patogener så som varroakvalster, nosemasjuka och deformed wing virus till humlor vilket leder till minskad livslängd och sämre fortplantning..
Retrospektiv studie av porcint circovirus typ 2 och postweaning multisystemic wasting syndrome i Sverige :
Porcine circovirus type 2 (PCV2) is a common virus present in most parts of the world.
PCV2 has been pointed out as the major causative agent to post weaning multisystemic
wasting syndrome (PMWS) that affects pigs after weaning. The clinical symptoms of PMWS
are impaired growth, diarrhoea, respiratory problems and increased mortality. At autopsy
enlarged lymph nodes with depletion of lymphocytes are commonly found.
Since 1991 PMWS has spread all over the world and was first described among Swedish pigs
in 2003. Although PCV2 is widespread, only some pigs develop PCV2-related diseases.
Why this is and what other factors that are required in order for the disease to develop is yet
unknown. The main theories involve other infections, for example PRRS, and management
issues but also genetic differences between pigs and/or virus strains have been suggested.
BVC-sjuksköterskors upplevelser av arbetet med omsorgssviktande familjer
Many children in Sweden are exposed to maltreatment. Among the purposes of the Child health care (CHC) are to decrease mortality, infirmity and handicaps among mothers and their children, and to decrease hurtful strains for parents and their children. CHC-nurses get critizism for not reporting child maltreatment in high enough numbers to the Social service. The aim of this study was to chart how CHC-nurses finds their work with families suffering from maltreatment. Ten CHC-nurses were interviewed with semistructured interviews.
Balis trädgårdar
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
Kemiskt försvar mot havstulpanskolonisering i marina svampdjur
The purpose of this project is to analyze and study the absorption of the substances ivermectin, spinosad and barettin to hydrophobic and hydrophilic surfaces, and to analyze and study if the barnacle larva are effected when they try to settle on the treated surface.Incubation tests with barnacle larva in Petri dishes were performed as well as absorption tests on hydrophobic and hydrophilic surfaces which were tested with ellipsometry. To determine the surface thickness.The barnacles were placed in hydrophobic as well as hydrophilic Petri dishes that had been incubated with ivermectin, spinosad or barettin. After four to six days the larva was counted to analyze the settling. From the results conclusions could be drawn about the adsorption abilities of the substances to the different surfaces.The barnacles were placed in hydrophobic as well as hydrophilic Petri dishes that had been incubated with ivermectin, spinosad or barettin. After four to six days the larva was counted to analyze the settling.
Födelseordningens påverkan på smågrisens överlevnad och tillväxt fram till avvänjning
Syftet med den här litteraturstudien var att undersöka hur födelseordningen påverkar smågrisens överlevnad och tillväxt fram till avvänjning. Födelseordningen bestäms till stor del redan i livmodern och en sen födelseordning minskar smågrisens chanser att överleva på flera sätt. Smågrisar med en sen födelseordning har ofta en lägre födelsevikt och födelsevikten anges återkommande vara den viktigaste faktorn för att öka chanserna till överlevnad. En stor kullstorlek leder till att födelsevikten minskar genom att placentaarean för varje smågris minskar. Smågrisar med en sen födelseordning löper också en högre risk att födas med en brusten navelsträng eller att drabbas av syrebrist under födsel.
Nytta, skada och kostnader vid screening för bröstcancer med mammografi
The efficacy of screening for breast cancer with mammography has been a subject of controversy during the last decades. However, the general opinion is now that screening reduces mortality in breast cancer (Zackrisson, 2006). It is nevertheless important to weigh the efficacy against the harm and costs associated with screening. Cost-utility and cost-effectiveness analysis of screening have generally failed to incorporate side effects such as anxiety and discomfort related to screening tests and the following diagnostic tests (Gyrd-Hansen, 2000). This study seeks to include such side effects in a cost-utility analysis.
