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.
