The present study was carried out to observe the impact of different roofing materials on certain physiological parameters of Magra lambs at Livestock Research station Bikaner. Eighteen Magra lambs of 3-4 months of age were randomly divided into three groups T₀ (Control group having tree shed), T₁ (Thatch roof shed), and T₂ (Tin roof shed). All three groups of lambs were managed under a similar system of feeding and other management systems. Physiological parameters viz. rectal temperature, respiration rate, heart rate and pulse rate of experimental lambs were measured and recorded data were analyzed. Results indicated significantly (p<0.01) lower rectal temperature and respiration rate in lambs maintained under thatch roof system than T₀ and T₂ groups. Mean values of heart rate and pulse rate in experimental lambs differed non significantly among the treatment groups.
