Environmental temperatures of approximately 75° F for hogs weighing 70 to 144 pounds and 60° F for hogs between 166 and 260 pounds were the temperatures under which experimental swine at Davis made the largest daily gain and required the least amount of feed to produce 100 pounds of gain when the temperature was kept constant.
