Abstract:
The present study conducted to know the effect of microclimate alteration devices and feed additive on re productive performance of Murrah buffaloes in summer. Total 24 Murrah buffaloes were selected. They were distributed into randomized block design (RBD) as T₁ (foggers) T₂ (fans), T₃ (fans plus feed additive containing Chromisac (Chromium plus yeast) @ 500 g/ton of feed) and control. All the animals in groups were analysed for reproductive performance based on estrous signs, intensity of estrus, estrous response and duration of estrus. The present study revealed estrus response and duration of estrus was 66.66, 33.33, 33.33, 16.66 percent, and 23.8±6.2, 15.33±2.2, 16.3±0.8 and 13 hours in T_1, T₂, T₃ and control groups respectively. The present study concluded that reproductive performance is higher in T₁ and T₃ compare to T_2, and control. Hence foggers as microclimate alteration device was more advantageous compare to other.
