Potential summer heat-stress of sheep at Greek husbandry areas of different landscape CIGR Journal
Panagakis, Panagiotis.
During the last years and due to its economic importance sheep farming expands at flat land areas in Greece exhibiting less favourable climatic conditions especially during summer. It is therefore justifiable to assess the potential summer heat-stress of sheep growing at areas of different landscape. Potential heat-stress of sheep during summer was studied at three Greek husbandry areas of different landscape, namely Larissa - flat land, Ioannina - semi-mountainous and Trikala Korinthias - mountainous. Indices used were the night hours during which ambient temperature was below 21ºC, the Temperature Humidity Index (THI), the time percentage (%) within predefined heat-stress categories and the THI-hrs index. Overall, the area of Larissa exhibited the worst...

Environmental conditions, potential heat-stress state and their relations in a sheep barn under hot climate CIGR Journal
Papanastasiou, Dimitris K.; Panagakis, Panagiotis; Anestis, Vasileios; Bartzanas, Thomas; Skoufos, Ioannis; Tzora, Athina; Kittas, Constantinos.
The aim of this study was to examine climate conditions, air quality, potential heat stress and their relations in a sheep barn under Greek hot weather conditions. Hourly averaged values of temperature, relative humidity, wind speed, and coarse and fine airborne Particulate Matter (PM) concentration recorded inside and outside a naturally ventilated sheep barn during July, August and September of 2015 were used. Indoors potential heat-stress levels were assessed by means of the Temperature Humidity Index (THI). Descriptive statistics were presented and relations between the environmental parameters and the THI values were investigated. The results showed that inside the sheep barn, THI was positively correlated (p < 0.0001) with temperature and wind...
