INCREASED UTILIZATION OF SENSIBLE HEAT-LOSS MECHANISMS IN HIGH-TEMPERATURE, HIGH HUMIDITY CONDITIONS

Models of heat loss partition in poultry suggest that, above the zone of thermoneutrality, insensible heat loss increases while sensible hea t loss mechanisms decline in importance. Comparison of evaporative and total heat losses at low and high relative humidities suggest this ma y not be correct at high temperatures and high humidities.
