This study aimed to evaluate the impact of
evaporative cooling during late gestation on physiological
responses, blood gas and acid base balance and subse quent milk production of Murrah buffaloes. To investigate
this study sixteen healthy pregnant dry Murrah buffaloes
(second to fourth parity) at sixty days prepartum were
selected in the months of May to June and divided into
two groups of eight animals each. One group of buffaloes
(Cooled/CL) was managed under fan and mist cooling
system during dry period. Group second buffaloes
(Noncooled/NCL) remained as control without provision
of cooling during dry period. The physiological responses
viz. Rectal temperature (RT), Respiratory rate (RR) and
Pulse rate were significantly (P < 0.05) lower in group 2,
with the provision of cooling. Skin surface temperature at
thorax was significantly lower in cooled group relative to
noncooled group. Blood pH and pO2 were significantly
(P < 0.05) higher in heat stressed group as compared to
the cooled group. pCO2, TCO2, HCO3, SBC, base excess
in extracellular fluid (BEecf), base excess in blood (BEb),
PCV and Hb were significantly (P < 0.05) higher in
cooled group as compared to noncooled group. DMI
was significantly (P < 0.05) higher in cooled relative to
noncooled animals. Milk yield, FCM, fat yield, lactose
yield and total solid yield was significantly higher
(P < 0.05) in cooled group of Murrah buffaloes.
