Parameters of health, productivity, behaviour and physiology which are used in order to determine the stress shaped by the effects of various factors in poultries can only be detected when the effects of stress emerge; in other words, when the changes are shaped. Therefore; it is important to interfere before the emergence of these indications in order to develop animal welfare by preventing stress. Information programmes, as traditional methods, and vitamin applications as well as anti-stress effects of herbal extracts have recently been studied in order to reduce the effects of stress. Moreover; such applications as crossbreeding native race, which are highly tolerated against temperature stress, with the commercial ones, usage of blue LED light, capturing exercises, enriched environment, adding roosters into the flocks of hen and finally temperature exercises in chick period are also tried as anti-stress preventions. In this paper, new approaches to the reduction of stress or stress sensitivity in poultries have been studied.
