| 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... |
