Effect of three lifetime ambient temperatures on growth, feed and water consumption and various blood components in male and female Leghorn chickens.
In two trials, SC White Leghorns were subjected to constant ambient temperatures of 21.1, 29.4, and 35.0 C from 2 to 31 or 32 weeks of age. Weekly measurements were made of body weight, feed efficiency, water consumption, red blood cell count, hemoglobin, hematocrit, total plasma protein, Po2, Pco2, pH, and mortality. It was found that the blood picture changes with age, sex, and ambient temperature. Age at which sex differences become significant varies with the blood component studied.
