The Effects of Temperature Stress on Subsequent Egg Production of the Fowl

Abstract

THE effects of short term high and low ambient temperature stress during the growing period on subsequent egg production of the fowl has not been investigated. However, Huston et al. (1957) found that White Leghorn hens laid as well when exposed to a constant temperature of 32.5°C. (90°F.) as those in a variable natural environment. Various other workers have reported that a high temperature, above 29.5°C. (85°F.), in the laying house reduced egg production, egg size, and egg quality.Air movement has also been shown to influence the bird’s resistance to both heat and cold. Lee et al. (1945) found that the rise in rectal temperature was somewhat reduced by increased air movement up to 91.4m. (300 ft.) per minute in hot humid atmosphere. Wilson et al. (1957) demonstrated that cold winds at the rate of 91.4 m. (300 ft.) per minute or more reduced the growth rate of White …
