The protein-bound iodine-131, the concentration of iodine-131 in blood, and the excetion rate of I-131 through urine and feces were observed in nine Korean native goats, 3 months age, following administration of 3 μC of I-131 per ㎏ of body weight.
No signiant differences were found due to sex and castration.
1. The average protein-bound iodine-131 conversion ratio of goats was 16.7% in 24 hours. In castrated group, the lowest proteinbound iodine-131 conversion ratio was observed.
2. The average concentration of iodine-131 in bleed, increased very rapidly by 2 hours(4.75%) and rapidly decreased within 6 hours(0.73%).
3. The average excetion rate of I-131 through urine was highest in 24 hours(19.00%) and decreased rapidly within 48 hours(5.32%).
4. The average excetion ration rate of I-131 though feces was highest in 24 hours(2.55%), and decreased slowly.
