An attempt was made to assess the effect of improved nutrition and improved shelter on pulse rate in lambs either alone or in combination. An experiment was conducted at ICAR-ARC-CSWRI, Bikaner in two phases. In each phase, forty male Magra lambs of 15 days old age were taken from ARC-CSWRI, Bikaner; ten lambs in each group were used in a randomized block design up to the six months of age, born during season 1 and season 2. Physiological variable viz, pulse rate of lambs was recorded twice a day (morning and afternoon) at fortnightly intervals. The obtained results about meteorological variables collected through datalogger indicated that there was wide variation in temperature and THI and because of this; there were fluctuations in pulse rate of lambs which varied with the changes in the environmental temperature. In treatment groups there were no fluctuations in pulse rate of lambs which indicate that lambs were comfortable. At the end, it appears that incorporation of both improved nutrition and improved shelter is better strategy for mitigation of thermal stress in animals.
