Extract

Open front pole barns have proved to be very economical for the housing of feeder cattle, dry stock and, in certain areas, milking cows in Canada. In California, Heitman and Hughes (1949), Heitman, Kelly and Bond (1958) and Heitman, Kelly and Hughes (1949) investigated the effect of ambient temperatures (40 to 110° F.) and humidity on rate of gain in swine. Optimum temperatures for rate of gain were 73·5° F. and 61° F., for pigs of 100 lb. and 300 lb. live-weight, respectively. Hazen, Currie and Giese (1950), at Iowa State College, showed that growing swine weighing under 100 lb. are less severely affected by cold weather (34 to 40° F.), when protected from wind and wet, than heavier animals are by high temperatures.
