In hot arid and semi-arid regions, heat stress is a major constraint in animal production due to prolongedsummers with high temperatures. In dairy husbandry, the desert cooler and evaporative cooling systemare effectively used to reduce heat stress. However, the effectiveness of desert coolers on sheep under thehot semi-arid region during summer is not explored. Therefore, the present study was carried out toassess the effect of the provision of the desert cooler in a shed of ewes during the summer in the hotsemi-arid region. For this purpose, 20 acyclic Malpura adult ewes having bodyweight 30.29 0.5 kg of 2-to 3-year-old were selected from the experimental animalflock. The ewes were equally divided into twogroups, namely G1 (control) and G2 (desert cooler). Ewes of both groups were kept in a roofed shed, withmud-floored and four sides covered with the chain-linked fence. The ewes of G2 were provided with adesert cooler from morning 09:00 h to evening 18:00 h. Ewes of both the groups were provided with anad libitumdiet consisting of 70% roughage (Cenchrus ciliarishay) and 30% concentrate feed. The mete-orological parameters were recorded daily in the morning and afternoon. The body weight and physi-ological response were recorded on a weekly basis. The blood sample was collected at weekly intervals toestimate blood biochemical and endocrine parameters. The data were analyzed using a general linearmodel. The maximum temperature, relative humidity, and temperature-humidity index in the afternoonwere significantly (P
