摘要：

After storage at 12.degree. C and 90-95% humidity, for periods of 1, 5, 8, 11 and 14 days, Rhode Island Red eggs were incubated at 37.5.degree. C and 60% humidity. Whatever the total duration of incubation within the experimental conditions, maximum serum levels of triiodothyronine (T3) and thyroxine (T4) were obtained the day of pipping. Embryo shaving perforated the air-space membrane the day before pipping showed elevated serum T3, but not T4, levels as compared to embryos without a perforation. The lower serum T3 levels obtained at pipping after longer periods of preincubation storage are discussed in relation to other experiments on perinatal changes in serum iodohormones.
