In hot region animal received heat from environment and from feed they eat leading to heat stress. This study aimed to evaluate the effect of different energy sources in the diet on physiological responses of sheep. Sixteen ewes were allocated into completely randomized block design with four treatments and four replicates. The diet treatments were P1 = 100% forages, P2 = forages 40% + concentrate 30% + cassava flour 30%, P3 = forages 40% + concentrate 50.3% + palm oil 9.7%, and P4 = forages 40% + concentrate 50.3% + canola oil 9.7%. The variables measured were rectal temperature, respiration rate, heart rate, haematocrite, water intake and faecal dry matter. The data were analysed using analysis of variance (ANOVA) and were further tested using Duncan’s multiple range test. The results showed that sheep fed cassava flour (P2) had higher (p<0.05) respiration rate than those of other groups. Different energy source had no effect on heart rate, rectal temperature, water intake, faecal dry matter and haematocrite value. It is concluded that cassava flour cause to increase respiration rate of sheep higher than those supplemented with palm oil and canola oil resulting no differences in other physiological responses among the three treatments.
