Supplementing natural air movement with fans during two summers in the Imperial Valley of California (average daily temperatures were near 90° F.) indicated the following: No significant increases in animal productivity could be attributed to increased air velocity when shade was available to animals in wire or cable corrals. Fans significantly lowered rectal temperature, surface temperature,and respiration rate when no shade was available, and did not affect these parameters when the animals had shade. Water intake per pound of dry matter consumed was lowered by shade and by the combination of shade and a fan. Wire corrals provided a more comfortable summer environment than wooden corrals.
