Abstract
Serum thyroxine level was determined monthly for fifteen Holstein cows by radio stereoassay using polyvinyl alcohol (PVF) sponge throughout a year to investigate the effects of season, pregnancy and lactation on the thyroxine level seasonably, the serum thyroxine level was low in summer, and the average level in July and August was 12.6 ..mu..g/dl, which was a half of the average winter level in January and February of 26.2 ..mu..g/dl. It became low level at the late stage of gestation, showing the lowest value of 13.7 ..mu..g/dl just before delivery, and increased suddenly in the second month of lactation attaining the highest level of 27.0 ..mu..g/dl. It reduced slightly thereafter to be 22.1 ..mu..g/dl at the end of lactation.
