    Sammanfattning : Horses are used in a variety of disciplines partly as a hobby as well as for competitions at the elite level. Regardless of how the horse is used, the horse owner is obliged to help the horse with its heat balance with a blanket if necessary. However, there is a widespread lack of knowledge on when to use the blanket and if it really is needed. LÄS MER

    Nyckelord :dairy cows; core body temperature; rectal temperature; skin temperature; infrared camera;

    Sammanfattning : Lactating cows have a higher heat production due to the milk synthesis compared to dry cows. In the regulation and general advice regarding animal husbandry (SJVFS 2010:15) it is stated that animals should be kept in thermal comfort. LÄS MER

  4. 3. Thermal comfort in young broiler chickens (Gallus gallus domesticus) inferred from metabolic expenses.

    Nyckelord :Oxygen consumption; Thermoneutral zone; Young broiler chickens; Random ambient temperatures; msVO2.;

    Sammanfattning : The thermoneutral zone (TNZ) curve lies between the ambient temperatures (Ta) where an endothermic animal uses the least amount of energy to maintain a balance between the heat production from the animal’s own metabolism and the heat lost to the environment. If the animal is exposed to Ta’s over the upper critical temperature (UCT), which is the highest temperature that is still in the TNZ, the animals have to use energy to cool down. LÄS MER

    Sammanfattning : Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. LÄS MER
