The present experiment was conducted at ICAR-ARC-CSWRI in a phased manner (Autumn-Winter season and spring-summer season) to observe the effect of improved nutrition and improved shelter either alone or in combination on respiration rate in Magra lambs. In each phase, fifteen days old Magra lambs (n=40) were used in a randomized block design upto the six months of age and divided into four groups of 10 lambs in each group (T1-T4). There was wide variation in temperature and THI during the study period, which indicated that lambs were under thermal stress during various months of trial. The negative effects of thermal stress caused fluctuations in respiration rate, which might be improved by the provision of improved nutrition and improved shelter alone or in combinations.
