Abstract :
THE possibilities of artificially increasing the comfort, or, more correctly, the efficiency of use of feed by farm livestock, are great. The range of optimum temperatures for laying hens is 55 to 65 F (degrees Fahrenheit), for dairy cows 50 to 60 F, and for swine 65 to 75 F. Size and age of animal, sex, coat, etc., are all related to its ability to resist high or low temperatures. Adverse effects are apparent sooner from high than from low temperatures; in general, livestock are considered to be depressed by temperatures over 75 F.
