Resting metabolism of Yucatan miniature swine

Oxygen consumption, carbon dioxide production, rectal temperature and skin temperatures were measured in six conscious Yucatan miniature swine. Heat production was calculated from oxygen consumption and carbon dioxide production data. Under ambient conditions (20 degrees C), the parameters studied were similar to what has been reported for conventional domestic swine. During 90 minutes of cold exposure (0 degrees C), oxygen consumption increased by approximately 50%. At 0 degrees C, excessive shivering and grunting were noticeable and were associated with decreases in skin and rectal temperature.
