Extract

It is generally recognized that at high temperatures egg production is reduced. Although Hutchinson (1954) reported that hens will lay at 44°C, the highest constant temperature under which laying hens have been kept under research conditions is 38°C for 8 weeks (Smith and Oliver, 1972a). Both feed intake and egg output were greatly depressed and at the end of the experiment the hens were reported to be “approaching death” (Smith, 1970).
