Abstract

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