摘要：

Twelve adult Muzaffarnagari rams (mean weight 41.3 +/- 2.09) were used to study fasting heat production (FHP) using open circuit respiration calorimetry. After a maintenance level of feeding for 60, sheep were fasted for three days and later subjected to gaseous exchange studies for 72-96 h. Mean oxygen consumption, carbon dioxide and methane production (1/d) and urinary nitrogen excretion (g/d) values for sheep were 187.9, 130.4, 0.346 and 2.94, respectively. Mean fasting heat production of sheep was 54.1 kcal/kg W-0.75 per day and feeding rations with different roughage to concentrate ratio at maintenance level prior to fasting had no effect on FHP.
