EFFECT OF FOGGERS ON MICROCLIMATIC CHANGES AND PHYSIOLOGICAL RESPONSES OF MEHSANA BUFFALOES IN SUMMER SEASON
2017

未知. The trial was conducted during hot dry season when the average maximumtemperature was 38.54°C (36.60 to 40.20°C) and relative humidity was 53.45% (46.00 to60.00%) at Livestock Research Station, S.D.A.U, Sardarkrushinagar. The average dry bulbtemperature decreased by 0.19°C and relative humidity increased by 2 - 2.5 % due tocooling effects of foggers at afternoon hours in experimental shed. The animals were dividedinto two groups of six each. Buffaloes of Group I were kept under loose housing withoutfoggers (control), while buffaloes of group II were kept under loose housing with foggers(experimental). The foggers were operated daily during hot hours from 12:00 to 15:00 p.m. inexperimental shed. The fogger cooling system was automatically controlled by an electronictimer and run for 3 min after an interval of every 2 min (36 min/hour) from 12:00 to 15:00hours. The mean values of physiological responses for rectal temperature, respiration rateand pulse rate of both the groups were not different during morning but varied (P<0.01) inthe afternoon. Water cooling through foggers played important role in body comfort of animalwhich is evident from the lower rectal temperature, respiration rate and pulse rate ofMehsana buffaloes in experimental shed by 0.55°F, 4.56 counts/minute and 5.62 beats/minute, respectively at the peak hot period of afternoon hours.
