Description The present investigation was conducted in male buffalo calves to study the effect of electrolyte supplementation during hot-dry and hot-humid climatic conditions on physiological responses. Healthy male buffalo calves (8), 18 to 20 month-old, weighing 255±10 kg body weight were divided into control and treatment groups of 4 animals each. The treatment group was supplemented with electrolytes (NaHCO3, K HCO3 and KCl). The animals were maintained under uniform animal husbandry practices. The experiment was conducted in 2 phases, hot-dry (40°C with 30% RH) and hothumid (35°C with 70% RH). Both control and treatment groups were exposed to heat stress in psychrometric chamber on above described temperatures and relative humidity for 4 h daily for 21 days in each phase. Physiological responses were recorded at every day pre-exposure and post-exposure to heat stress. The physiological responses (rectal temperature, respiration rate/min and pulse rate/min) were increased significantly post exposure compared with pre-exposure in both groups during hot-dry and hot-humid conditions. But the increase was significantly higher in control group compared with treatment group. The increase in respiration rate and rectal temperature was significantly higher during hot-dry compared with hot-humid. Supplementation of electrolytes during heat stress helps in maintaining the physiological responses of male buffalo calves. Therefore electrolyte supplementation tends to reduce the heat stress in buffaloes during summer months.
