Performance of laying hens in a cognitive bias task : effect of time since change of environment

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.

Utveckling av en fiberberikad probiotisk fruktdryck

The purpose of this study was to investigate whether resistant maltodextrin is suitable as a fiber source in the probiotic fruit drink ProViva Mango without affecting the probiotic bacterium Lactobacillus plantarum 299v, viscosity or the sensory experience of the drink. Resistant maltodextrin is produced from hydrolyzed corn starch and is classified as a soluble dietary fiber. It is relatively resistant to digestion in the small intestine, where approximately 10% can be broken down, 50% can be fermented in the colon by the intestinal flora and 40 % is excreted in the faeces. Resistant maltodextrin has several important qualities when it comes to food processing. When added in a product, it does not affect the viscosity or taste and it is heat and acid stable.

Selection was made at libraries and on?line through "Pubmed". Specific search words were used.

Wilhelm Reichs mottagande i Sverige psykoanalys, marxism, biologi och kosmologi

In this essay I have been writing about the psychoanalyst Wilhelm Reich. It was written at the Library School in Borås as a contribution to the struggle of the maintenance of the free word. In the essay I have been concentrating on how Reich was received in Sweden from the publication of his first book 1927 to the year of 2000. The work started with a biographical chapter and a chapter about Reich's scientific development, which was divided into three phases: one psychoanalytical and Marxist, one physiological and biological and a third phase that makes a synthesis of these in a cosmological form. The analytic material has been books and articles from periodicals and papers.

Dogs' behavioural responses to repeated positive events

Assessing the emotional state in animals is important in order to establish the quality of their welfare, therefore it is important to investigate under what circumstances animals experience these emotions and to find indicators of their existence. The aim of this thesis was to detect possible behavioural indicators for positive emotions in dogs. These behavioural indicators could be helpful to increase both dogs? and humans? overall well-being in today?s society since they could help e.g. dog owners and caretakers to interpret behaviours displayed by dogs and their intentions so they can respond accordingly.The subjects used were 9 research beagles and each dog participated in three different treatments, assumed to be experienced as positive situations, where communicative interaction was initiated with the dog by engaging in 1) physical contact (P), 2) verbal contact (V) or 3) both physical and verbal contact simultaneously (PV).

Snusets påverkan på balans : skillnad i posturalt svaj hos dagligsnusare före och efter uppehåll från snusbruk

SyfteSnusandet har ökat de senaste åren, särskilt bland kvinnor och yngre personer och till flera samhällsgrupper. Rökning har under många år genomgått rigorös forskning och därigenom bevisats vara förenat med ohälsa. Däremot är forskning på snusanvändandets hälsoeffekter eftersatt. En fysiologisk effekt som föreslagits av långvarigt snusande är påverkan på balans (posturalt svaj). Uppsatsens huvudsyfte är att undersöka effekten på balans av ett långvarigt (sex veckor) uppehåll från snus i en grupp av dagligsnusare. MetodI studien genomförde dagligbrukare av snus (n=13) tester av posturalt svaj före och efter sex veckors uppehåll från snus.

Neuromuskulär återhämtning efter matchspel hos professionella fotbollsspelare

During football games neuromuscular fatigue occuring following eccentric movements such as sprint, jump and run that occur during games. To avoid injury, overtraining and performance decreases, it is important to know when players are recovered. The aim of the pilotstudy was to investigate physiological changes that occur during football matches and if they affect the recovery pattern after several games in professional football players. The method was divided into two sub-studies in which 12 professional footballers, in substudy 1 performed counter movement jump (CMJ) and drop jump (DJ) from 40 cm and fill out a recovery form for muscle soreness 36 hours before, 12-16 and 60-64 hours after 11 different competetive games. Blood samples were taken on the players in connection with one match to examine the activity of muscle enzyme creatine kinase (CK) and lactate dehydrogenase (LDH) of the players.

Distriktssköterskans erfarenheter av samtal med patienter, med hypertoni

Hypertension is one of the most common reasons for visiting primary care. It is one of the most important modifiable risk factors for cardiovascular disease, suffering and death.

Selenium in Swedish sheep production

Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.

Anestesi av det neonatala fölet

Every spring you can see newborn foals running on fields among the mare. But some unfortunate end up visiting the equine hospital requiring surgery. This is a challenge for the anesthetist because of the neonatal foal?s unique physiology. Therefore you need to take these differences under consideration when you anesthetize foals.

En validitetsstudie på beeptestet : avseende maximal aerob kapacitet för elitishockeyspelare

Introduction: This study aimed to investigate the validity and reliability of the 20m multistage shuttle run test (MST) for elite ice hockey players as a predictor of the maximal aerobic capacity and the how the result is affected by the players age, aerobic and anaerobic capacity, body composition and test surface. The purpose of this was to find out the potential of the 20-m shuttle run test as a measuringtool for the maximal aerobic capacity in frequent testing periods during the season. It is very interesting to be able to administer this easily because the competative phase of the season is very long compared to the pre-seasonal phase and earlier studies have shown that the aerobic capacity is being lowered during this competative phase of the season for elite icehockey players.Methods: 34 elite ice hockey players participated in this study (20.0±3.6 yrs, BMI 24.2±1.6 and VO2-max 58.0±4.8 ml O2?kg-1?min-1). During 3-5 days they underwent 2 MST tests (wood and rubber surface), treadmill running with VO2-max assessed with open-circuit technique, Wingate10% and FFM-assessment with underwater-technique.
