摘要：

Commercial male broilers were used in 5 trials conducted to determine whether lowering the temperature during the cool portion of the 24-h period in summer affected broiler performance. Treatments used were 24-h linear temperature cycles ranging from a high of 35.degree. C to a low of either 26.7.degree. or 21.1.degree. C. Lowering the low portion of the temperature cycle from 26.7.degree.-21.1.degree. C during the 24-h period significantly increased broiler body weight at 48 days of age.
