Summary

A single, brief cooling episode during incubation did not significantly affect body weight or hematocrit values in 23-day-old turkey embryos. Based on a differential classification of white blood cell (WBC) in the blood smears of these turkey embryos, there were 82, 10, 8, less than 1, and less than 1% of heterophils, lymphocytes, basophils, eosinophils, and monocytes, respectively. Circulating heterophils, the most numerous WBC in turkey embryos, were significantly reduced in all embryos cooled during the latter half of incubation. This effect was mirrored in the total WBC numbers counted. The effect of cooling on the other classes of turkey embryonic WBC, which represent about 20% of the circulating WBC, were more variable.
