The objective of the study was to observe the effect of evaporative cooling during late gestation on immunity around the transition period and the probable outcome on reproductive disorders in Murrah buffaloes. Sixteen pregnant dry Murrah buffaloes at 60 days prepartum were selected and divided into two groups of eight animals each. Group 1 buffaloes remained without the provision of cooling, whereas the second group of buf faloes was managed under fans and mist cooling during the dry period. After parturition, all the animals were managed under evaporative cooling. Dry matter intake was signifi- cantly (P < 0.05) higher in cooled relative to noncooled animals at 15, 0, and þ20 days of parturition. Cortisol and prolactin levels were significantly (P < 0.05) higher in noncooled relative to cooled animals at 15 and 0 days of parturition. However, prolactin was significantly (P < 0.05) higher in cooled animals at þ20 days. Messenger RNA expression of prolactin receptor gene (PRL-R) was upregulated and suppressor of cytokine signaling gene 1 (SOCS-1) was downregulated in cooled animals at 20, 0, and þ20 days of parturition. Tumor necrosis factor a and interleukin 4 levels remained significantly (P < 0.05) higher in cooled animals at 20, 0, and þ20 days of parturition. Interleukin 6 was significantly (P < 0.05) lower in cooled animals at 20 and 0 days. Interferon g levels were significantly higher at 20 and þ20 days of parturition in cooled relative to noncooled animals. The reproductive disorders such as retention of placenta, metritis, and endometritis occurred at the rate of 37.25%, 25%, and 12.25% in the noncooled group, whereas only retention of placenta was observed in the cooled (12.5%) group.
