Juvenile partridges, maintained on long (20L:4D) daylengths from hatch, were radiothyroidectomized at 6 1/2 weeks of age, and after 2 weeks were either held on long days or transferred to short (8L:16D) daylengths. Short-day thyroidectomized birds showed no evidence of gonadal growth 18 weeks after thyroidectomy, and neither did euthyroid controls… CONTINUE READING
