Modulations in energy metabolism during adverse ambiences were investigated in Marwari breed of sheep belonging to arid tracts. Blood samples were collected to prepare sera from male and female goats of varying age groups during moderate, extreme hot and extreme cold ambiences. Modulations in energy metabolism were assessed by analyzing serum cholesterol, triglycerides and glucose and the mean values (mmol L-1) were 3.2±0.03, 1.25±0.01 and 3.6±0.02, respectively during moderate ambience. The mean value of serum triglycerides was significantly (p<0.05) lower during hot and cold ambiences whereas the mean values of cholesterol and glucose were significantly (p<0.05) lower during hot ambience and significantly (p<0.05) higher during cold ambience as compared to respective moderate mean value. Significant (p<0.05) changes were observed in the value of each parameter according to sex and age. It was concluded that extreme hot and cold ambient temperatures affected the energy metabolism of animals of both sexes and all age groups which was evident in the form of variations in the metabolic responses to combat the ambient stress.
