The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

Går det att mäta blodtryck med fotopletysmografi och bioakustisk sensor i kombination?

The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Hydroperikard hos katt : patofysiologi, diagnos och behandling

Hydropericardium or pericardial effusion (PE) is the accumulation of fluid in the pericardial sac and is often secondary to pericardial diseases or diseases related to the heart. It is unusual with clinically relevant pericardial diseases in cats but pericardial effusion is the most common one. Since PE causes serious symptoms and may lead to death it is important with a quick diagnosis and treatment. PE can be acute and cause cardiac tamponade, which gives severe clinical signs. Cardiac tamponade needs to be treated immediately or else the cat will die from cardiogenic chock. More common is chronic PE where the fluid accumulates during a longer period of time and the pericardial sac stretches.

Arbetsprov i fält på ridhästar

Sport horses are widely used for performance in jumping, dressage, endurance etc. To enable comparisons of horses, training facilities, programs or physical status, an exercise test can be used. Exercise tests are also important to increase knowledge about exercise physiology of the horse considering different ways of training to compare training methods or individual qualities, development of an individual or other investigations of equine exercise physiology. Since several investigations are done on standard- and thoroughbred horses but less on sport horses, it is of great importance to get an overview of the investigations done. Most common is to investigate heart rate and lactate concentration.

En utvärdering av avelsprogrammet mot kronisk hjärtklaffsdegeneration hos Cavalier King Charles spaniels :

Chronic valvular disease (CVD) is the most common cardiac disease in dogs, which account for 75% of all the cardiac cases. Cavalier King Charles spaniel (CKCS) is the most affected breed and it´s 13th times more likely that a CKCS, between the age of 7-10 years, will die or be euthanized for cardiac disease, compared with other breeds. The prevalence has been proven to bee independent of coat color and weight but highly dependent on age and gender in CKCS. In 2001 the Swedish Kennelclub and the Special club for cavalier King Charles spaniel created a breeding program against CVD in CKCS. In this program dogs are not allowed to breed until 4 years of age and have to have a heart auscultation without murmurs.

Hur påverkas beteende/känslor och fysiologiska faktorer på människa och häst vid interaktion mellan parterna? :

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

Upplevelser av hjärtinfarkt hos kvinnor i det akuta skedet: En litteraturstudie

Sjukdomar i hjärtats kranskärl och dess komplikationer förorsakar 23% av alla dödsfall hos kvinnor i Sverige där akut hjärtinfarkt ensam står för 6% av fallen. Atypiska och diffusa symtom är en av orsakerna till att kvinnor med hjärtinfarkt inte alltid kommer till sjukhus i tid. Syftet med denna litteraturstudie är att belysa kvinnors upplevelser av hjärtinfarkt i det akuta skedet. Vi vill även få klarhet i varför kvinnor ofta väntar med att söka vård och dessutom riskerar att inte bli tagna på allvar. Vi har valt metod i form av en litteraturstudie där vi analyserar kvalitativ forskning som bygger på nio vårdvetenskapliga artiklar.

Prehospital omvårdnad av patienter med akuthjärtinfarkt som transporteras direkt till PCI : ? intervjustudie med sjuksköterskor i ambulans

The prehospital management of patients with acute myocardial infarction (AMI)now includes 12-lead electrocardiogram transmission directly from the ambulance to hospital.If the ECG shows ST-elevated myocardial infarction the patient should be transported directlyto a hospital with capability for percutaneous coronary intervention (PCI).                                               Aim: The aim of this study was to describe how ambulance nurses experienced the prehospital management of patients with AMI who are transported by ambulance directly to hospital for PCI.                                                Method: Semi structured interviews were conducted with eight ambulance nurses. Data were analysed using qualitative content analysis. The categories that emerged were: Use ofcompetence, Responsibility and Insufficiency. Result: The result showed that the ambulance nurses felt secure when they cared for patients transported directly to PCI. The nurses assessed the patient and decided how he or she should be cared for.

Livet efter hjärtinfarkten : En litteraturstudie om kvinnors erfarenheter

Hjärtinfarkt är den dominerande dödliga sjukdomen i Sverige, vilket fler kvinnor än män avlider i. Kvinnor insjuknar senare i livet och upplever fler och mer diffusa symptom än män. Stress är en vanlig förekommande riskfaktor, vilket kan skapas från samhällets förväntningar på kvinnor. Det finns förväntningar om omsorgsfulla kvinnor som samtidigt ska prestera bra både på arbetet och i hemmet, vilket genererar stress. Förväntningar från samhället och kroppens biologi skiljer sig mellan män och kvinnor.

When and what determines the death of an animal? A study investigating the heart activity during slaughter of farm animals

Slaughter of animals should consist of two steps in order to be considered humane. The first step of the slaughter process is stunning, with the purpose of inducing unconsciousness and insensibility in the animal. The second step is exsanguination, which causes bleeding and eventually death. What death really means in these situations has been discussed intensively, but still no agreed definition has been accepted. Nonetheless, it is conceded that animals are declared dead when consciousness is irreversibly lost, and absence of respiration and blood circulation are observed.

Wii Sports och Sport : En jämförelse av fysiska och emotionella skillnader och likheter i träningsspel jämfört med riktig träning

AimThe purpose of this study is to compare the level of activity between playing wii Sports Tennis and wii Sports boxing, and the usual sports, and to see how the two variants are perceived.Issues:- How much strain ratio and energy consumption it gives to exercise wii sports compared with the playing of sport for real?- How do the test participants experience the different tests?- How are the two wii sports games against each other in terms of activity and fitness in the school environment?MethodThis is an experimental study in which 10 test participants (5 men and 5 women) have carried out four different physical tests. The tests consisted of either playing an exergame or playing a sport for 25 minutes. Physical activity was measured during the test using a heart rate monitor. All test participants completed all tests in the same order.

Det sviktar - en litteraturstudie om hjärtsvikt

Allt fler personer drabbas av hjärt- och kärlsjukdomar, vilket på sikt kan leda till kronisk hjärtsvikt. För att förbättra omvårdnadsåtgärder för hjärtsviktspatienter har Socialstyrelsen 2004 givit ut nationella riktlinjer för hjärtsjukvård där vikten av en individuell handlingsplan betonas. Syftet med litteraturstudien är att undersöka på vilket sätt sjuksköterskor utför omvårdnadsåtgärder avseende fysisk aktivitet, egenvård, nutrition och rökstopp för patienter med hjärtsvikt och om dessa överrensstämmer med gällande riktlinjer samt om hänsyn måste tas till genusskillnader. Metoden är en litteraturstudie i databaserna PubMed och Elin@Malmö vilket resulterade i 14 artiklar som användes för att söka svaret på syftet. Som teoretisk referensram har Antonovskys KASAM modell använts.

Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet

In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).
