Abstract:
An attempt was made to study the effect of microclimate alterations on physiological parameters of buffalo heifers during summer at buffalo farm of LPM, LUVAS, Hisar (Haryana). Twenty buffalo heifers (8-18 months of age) were divided into four groups (5 heifers in each group) viz. T₁ (control): Corrugated asbestos roof; T₂: Corrugated asbestos roof painted white on upper side; T₃: Corrugated asbestos roof having EPE (Expanded polyethylene) sheet on lower side and T₄: Corrugated asbestos roof painted white on upper side and EPE sheet on lower side. Physiological parameters viz. respiration rate, pulse rate, rectal temperature were recorded fortnightly. The Morning values of physiological parameters viz. respiration rate, pulse rate and rectal temperature didn’t differ significantly whereas the evening values were significantly (P<0.05) higher in T₁. So it can be concluded that microclimate alterations by roof modifications using EPE sheets as well as white paint helped heifers in alleviating the thermal stress in heifers thereby improving physiological parameters during summer.
