Abstract
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 buffaloes 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 significantly (P < 0.05) higher in cooled relative to noncooled animals at â15, 0, and +20 days of parturition. Cortisol and prolactin levels were significantly (P < 0.05) higher in noncooled relative to cooled animals at â15 and 0 days of parturition. However, prolactin was significantly (P < 0.05) higher in cooled animals at +20 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 â20, 0, and +20 days of parturition. Tumor necrosis factor α and interleukin 4 levels remained significantly (P < 0.05) higher in cooled animals at â20, 0, and +20 days of parturition. Interleukin 6 was significantly (P < 0.05) lower in cooled animals at â20 and 0 days. Interferon γ levels were significantly higher at â20 and +20 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.
